WHY SEAS ARE RISING FASTER THAN FORECAST

Estimates of the rate at which the sea will rise may be too low, because it is rising faster than expected from global warming. The last official IPCC report in 2007 projected a global sea level rise between 0.2 and 0.5 metres by 2100, but current measurements meet or exceed the high end of that range and suggest a rise of one metre or more by the end of the century.

'What's missing from the models used to forecast sea-level rise are critical feedbacks that speed everything up,' says Bill Hay, a geologist at the University of Colorado.

This blog has said all along that the seas will be at least a metre and half higher in 2100. Now science is beginning to agree.

CLIMATE-CHANGE OZONE AND SKIN-CANCER

For decades, scientists have known that the effects of global climate change could have a potentially devastating impact across the globe, but Harvard researchers say there is now evidence that it may also have a dramatic impact on public health, reports ScienceDaily.

In a paper published in the July 27 issue of <i>Science,</i> a team of researchers led by James G. Anderson, the Philip S. Weld Professor of Atmospheric Chemistry, warn that a newly-discovered connection between climate change and depletion of the ozone layer over the U.S. could allow more damaging ultraviolet (UV) radiation to reach the Earth's surface, leading to increased incidence of skin cancer, because of the effects of the lightning generated by powerful storms on the chlorine and bromine high in the atmosphere, which in turn reduces the level of ozone.

PROOF THAT CLIMATE AND CO2 CLOSELY LINKED

New research from the Niels Bohr Institute at the University of Copenhagen indicates that, contrary to previous opinion, the rise in temperature and the rise in the atmospheric CO2 follow each other closely in terms of time. The results have been published in the scientific journal, Climate of the Past, reports ScienceDaily.

'What we are observing in the present day is the mankind has caused the CO2 content in the atmosphere to rise as much in just 150 years as it rose over 8,000 years during the transition from the last ice age to the current interglacial period and that can bring the Earth's climate out of balance,'says Sune Olander Rasmussen, Associate Professor and centre coordinator at the Centre for Ice and Climate at the Niels Bohr Institute.

The research, which was carried out in collaboration with researchers from the University of Tasmania in Australia, is based on measurements of ice cores from five boreholes through the ice sheet in Antarctica. The ice-sheet is formed by snow that doesn't melt, but remains year after year and is gradually compressed into kilometers thick ice. During the compression, air is trapped between the snowflakes and as a result the ice contains tiny samples of ancient atmospheres. The composition of the ice also shows what the temperature was when the snow fell, so it is an archive of past climate and atmospheric composition.

NOAA'S GLOBAL REPORT FOR 2011

Worldwide, 2011 was the coolest year on record since 2008, yet temperatures remained above the 30-year average, according to the 2011 State of the Climate report released online on July 10, 2012 by NOAA. The peer-reviewed report, issued in coordination with the American Meteorological Society (AMS), was compiled by 378 scientists from 48 countries around the world. It was reported on ScienceDaily.

The Arctic continued to show more rapid changes than the rest of the planet. Sea-ice shrank to its second smallest 'summer minimum' extent on record during 2011, as older ice (four to five years old) reached a new record minimum at more than 80% below average. Overall, glaciers around the world continued to lose mass. Loss from Canadian Arctic glaciers and ice caps were the greatest since measurements began in 2002.

The report used forty-three climate-indicators to track and identify changes and overall trends to the global climate system, including greenhouse gas concentrations, temperature of the lower and upper atmosphere, cloud cover, sea-surface temperature, sea-level rise, ocean salinity, sea-ice extent and snow cover. Each indicator includes thousands of measurements from multiple independent datasets.

Four independent datasets show 2011 among the 15 warmest since records began in the late 19th century, with annually-averaged temperatures above the 1981-2010 average. The Arctic continued to warm at about twice the rate compared with lower latitudes. On the opposite pole, the South Pole station recorded its all-time highest temperature of -22.1°C (9.9°F) on December 25, breaking the previous record by over 1 degree Celsius (over 2 degrees Fahrenheit).

Major greenhouse gas concentrations, including carbon dioxide, methane, and nitrous oxide, continued to rise. Carbon dioxide steadily increased in 2011 and the yearly global average exceeded 390 parts per million (ppm) for the first time since instrumental records began.

The extent of Arctic sea-ice was below average for all of 2011 and has been since June 2001, a span of 127 consecutive months.

The ozone-level over the Arctic was the lowest since records began in 1979.

Even with La Niña conditions occurring during most of the year, the 2011 global sea-surface temperature was among the twelve highest years on record. Ocean heat content, measured from the surface to 700 metres deep (2,300 feet), continued to rise since records began in 1993 and was a record high.

La Niña-related heat waves, like that experienced in Texas in 2011, are now twenty times more likely to occur during La Niña years today than La Niña years fifty years ago.

The UK experienced a very warm November 2011 and a very cold December 2010. In analyzing these two very different events, UK scientists uncovered interesting changes in the odds. Cold Decembers are now half as likely to occur now versus fifty years ago, whereas warm Novembers are now sixty-two times more likely.

NASA VIDEO SHOWS THE WORLD WARMING

This brilliant video from NASA  shows the change in temperature across the globe from 1880 to 2011. The colours show the amount of deviation from the 1951-1980 average. The animation clearly shows the warming trend, particularly since the mid-1970s, and the differences in different parts of the world so you can see how your part of the world has changed. 2011 was the ninth warmest year since 1880.

EXPECT THE SEA TO RISE 1.5 TO 4M

Sea-levels round the world can be expected to rise by several metres in coming centuries, if global warming carries on. Even if it is limited to 2 degrees Celsius, the global mean could continue to rise to 1.5-4m above present levels by 2300, with the best estimate being 2.7m, says a study just published in <i>Nature Climate Change.</i>

Reductions in emissions that allow warming to drop below 1.5 degrees Celsius could limit the rise strongly.

400PPM, TIPPING-POINT NEAR, ARCTIC EFFECT

The world recently passed the point where carbon-dioxide emissions have raised the level of that gas in the atmosphere to 400 parts per million.

By no coincidence a group of scientists around the world is warning that population growth, widespread destruction of natural ecosystems, and climate-change may be driving Earth toward an irreversible change in the biosphere, a global tipping-point that would have destructive consequences unless we do something.

'It really will be a new world, biologically, at that point,' warns Anthony Barnosky, professor of integrative biology at the University of California, Berkeley, and lead author of a review paper appearing in the June 7 issue of the journal <i>Nature.</i> 'The data suggests that there will be a reduction in biodiversity and severe impacts on much of what we depend on to sustain our quality of life, including, for example, fisheries, agriculture, forest products and clean water. This could happen within just a few generations.'

CO2 TO WARMING LINK IDENTIFIED

Many scientists have long suspected that rising levels of carbon-dioxide and the global warming that ended the last Ice Age were somehow linked, but establishing a clear cause-and-effect relationship between CO2 and global warming from the geologic record has remained difficult.

A new study, funded by the National Science Foundation and published in the journal Nature, identifies that relationship and provides compelling evidence that rising CO2 caused much of the global warming.

'CO2 was a big part of bringing the world out of the last Ice Age," says the lead author, Jeremy Shakun, 'and it took about 10,000 years to do it. Now CO2 levels are rising again, but this time an equivalent increase in CO2 has occurred in only about 200 years, and there are clear signs that the planet is already beginning to respond.'

The question now, say the researchers, is how carbon-dioxide generated by humans will affect the planet when there is no ice-age.

RISE IN SEA-LEVEL MORE ACCURATELY

A new study shows that the collapse of an ice sheet in Antarctica up to 14,650 years ago may have caused sea levels to rise between 14 and 18 metres, data which could help make more accurate climate-change predictions.

The melting of polar ice could contribute to long-term sea level rise, threatening the lives of millions, scientists say. Sea levels have increased on average about 18 centimetres since 1900 and rapid global warming will accelerate the increase, putting coastlines at risk and forcing low-lying cities to build costly sea defences.

A rise of 2 metres by 2100 is predicted.

By 2050, global average temperature could be between 1.4°C and 3°C warmer than it was just a couple of decades ago, according to a new British study that seeks to address the largest sources of uncertainty in current climate models. That's substantially higher than estimates produced by other climate analyses, suggesting that Earth's climate could warm much more quickly than previously thought.

OCEANS TO BE 20 METRES HIGHER

Even if humankind manages to limit global warming to 2 degrees C (3.6 degrees F), as the Intergovernmental Panel on Climate Change recommends, future generations will have to deal with sea levels 12 to 22 meters (40 to 70 feet) higher than at present, according to research published in the journal Geology and reported in ScienceDaily

ACIDIFICATION OF OCEANS UNPRECEDENTED?

The world's oceans may be turning acidic faster today from human carbon emissions than they did during four major extinctions in the last 300 million years, when natural pulses of carbon sent global temperatures soaring, says a new study in Science. The study is the first of its kind to survey the geologic record for evidence of ocean acidification over this vast time period.

MORE EXTREME SUMMERS IN THE US NOW

Extreme summer temperatures are already occurring more frequently in the United States, and will become normal by mid-century if the world continues on a business as usual schedule of emitting greenhouse gases, says a study led by Phil Duffy of the Lawrence Livermore National Laboratory. It showed that previously rare high summertime (June, July and August) temperatures are already occurring more frequently in some regions of the 48 contiguous United States.

'The observed increase in the frequency of previously rare summertime-average temperatures is more consistent with the consequences of increasing greenhouse gas concentrations than with the effects of natural climate variability, said Duffy. 'It is extremely unlikely that the observed increase has happened through chance alone.'

The team also modelled the period 2035-2064.

'What was historically a one in 20-year occurrence will occur with at least a 70 percent chance every year,' said Duffy 'This work shows an example of how climate change can affect weather extremes, as well as averages.'

CLIMATE-CHANGE MAKES 100-YEAR FLOODS EVERY 3-20 YEARS?

When Hurricane Irene spun through the Caribbean and parts of the eastern United States in August 2011 it generated storm-surges that swept over seawalls and flooded seaside and inland communities. Many hurricane analysts suggested that Irene was a '100-year event', a storm that only comes only once a century.
 
But researchers from MIT and Princeton University have found that with climate-change, such storms could make landfall far more frequently, causing powerful, devastating storm surges every 3 to 20 years.

The group simulated tens of thousands of storms under different climate conditions, and also found that today’s '500-year floods' could, with climate change, occur once every 25 to 240 years.

They published their results in the current issue of Nature Climate Change.

ARCTIC ALREADY AT DANGEROUS CLIMATE-CHANGE

Two decades after the United Nations established the Framework Convention on Climate Change to 'prevent dangerous anthropogenic interference with the climate system,' the Arctic shows the first signs of a dangerous climate-change, says a team of researchers in an article published recently in iNature Climate Change.

They say the Arctic is already suffering some of the effects that, according to the Intergovernmental Panel on Climate Change (IPCC), correspond with a 'dangerous climate change.' The rate of climatic warming now exceeds the rate of natural adaptation in arctic ecosystems.

NASA PROVES MAN NOT SUN IS WARMING EARTH

A study by NASA reported in ScienceDaily, shows that even during the unusually low period of solar activity between 2005 and 2010 the planet still absorbed more energy than it sent back into space--by 0.58 watts per square metre.

The imbalance of 0.58 watts per square metre is more than twice the reduction in energy from the sun during periods of reduced activity, which is 0.25 watts per square metre.

NASA says that is unequivocal evidence that human activity, not solar variance, is the dominant driver of global warming.

HUGE ARCTIC POOL COULD COOL EUROPE

A huge pool of fresh water in the Arctic Ocean is expanding and could lower the temperature of Europe by causing an ocean current to slow down, say scientists from University College London and Britain's National Oceanography Centre.

Using satellites to measure sea surface height from 1995 to 2010, they found that the western Arctic's sea surface has risen by about 15 cms since 2002. The volume of fresh water has increased by at least 8,000 cubic km, or about 10 percent of all the fresh water in the Arctic Ocean. The fresh water comes from melting ice and river run-off.

If the wind changes direction, which happened between the mid-1980s to mid-1990s, the pool of fresh water could spill out into the rest of the Arctic Ocean and even into the north Atlantic Ocean, which could cool Europe by slowing down an ocean current coming from the Gulf Stream, which keeps Europe relatively mild compared with countries at similar latitudes.

EARTHQUAKES LINKED TO TROPICAL CYCLONES

A groundbreaking study led by University of Miami (UM) scientist Shimon Wdowinski shows that earthquakes, including the recent 2010 ones in Haiti and Taiwan, may be triggered by tropical cyclones (hurricanes and typhoons).

'Very wet rain events are the trigger,' says Wdowinski, associate research professor of marine geology and geophysics at the UM Rosenstiel School of Marine and Atmospheric Science. 'The heavy rain induces thousands of landslides and severe erosion, which removes ground material from the Earth's surface, releasing the stress load and encouraging movement along faults.'

Wdowinski and a colleague from Florida International University analyzed data from quakes magnitude-6 and above in Taiwan and Haiti and found a strong temporal relationship between the two natural hazards, where large earthquakes occurred within four years after a very wet tropical cyclone season.

Which means that because global overheating will increase the number of tropical cyclones, bringing more heavy rain, we can also expect an increase in the number of significant earthquakes.

GREENLAND'S BEDROCK RISING

ScienceDaily reports that an unusually hot melting-season in 2010 accelerated ice loss in southern Greenland by 100 billion tons. Fifty GPS stations planted along the coast to measure the bedrock's natural response to the ever-diminishing weight of ice above it, showed that large portions of the island's bedrock responded by rising another 6mm (0.25 of an inch).

The bedrock rises 15mm a year, but the temperature spike in 2010 lifted it more in only five months--as much as 20mm in some places (0.79 of an inch).

WMO RANKS 2011 ONE OF THE WARMEST

<a href="http://in.reuters.com/article/2011/11/29/idINIndia-60792420111129">Reuters says</a> a report by the UN's World Meteorological Organisation ranks 2011 as one of the warmest years on record.

The WMO says global temperatures in 2011 are at the moment the tenth highest on record--higher than any previous year with a La Nina event, despite the fact that it has a relative cooling influence.

It says that this year the global climate was influenced heavily by the strong La Nina, a natural phenomenon usually linked to extreme weather in Asia-Pacific, South America and Africa, which developed in the tropical Pacific in the second half of 2010 and continued till May 2011. One of the strongest such events in 60 years, it was closely associated with the drought in east Africa, islands in the central equatorial Pacific and the United States, as well as severe flooding in other parts of the world.

The WMO says the warmest 13 years of average global temperatures have occurred in the 15 years since 1997. That has contributed to extreme weather conditions that increase the intensity of droughts and heavy precipitation across the world. The extent of Arctic sea ice in 2011 was the second lowest on record, and its volume was the lowest.

It says the build-up of greenhouse gases puts the world at a tipping-point of irreversible changes in ecosystems.

CLIMATE THREAT FROM HFCs

<a href="http://www.bbc.co.uk/news/science-environment-15818659">The BBC reports</a> on growing concerns that ozone-friendly HFCs are not friendly to climate-change, because the average global warming potential of the present mix of HFCs is about 1600--so a kilogram of HFC has about 1600 times the effect on global warming as a kilogram of carbon dioxide.

The HFCs: A Critical Link in Protecting Climate and the Ozone Layer, a report produced by the UN Environment Programme (UNEP), projected that the global warming potential of HFCs in 2050 could be comparable with present emissions from the global transport sector.

HOTTEST OCTOBER FOR NORTHERN HEMISPHERE LAND

The monthly figures prepared by the American government show that October 2011 was much warmer than normal compared with previous Octobers.

On average, land areas across the Northern Hemisphere—where the majority of the Earth's land mass is located—were the warmest on record for the month, at 1.29°C (2.32°F) above the 20th century average. The warmth was especially pronounced across Alaska, Canada, Mongolia, and most of Russia and Europe.

According to the UK Met Office, the United Kingdom marked its warmest October since 2006 and eighth warmest in the last 100 years, at 2.0°C (3.6°F) above the 1971–2000 average.

Norway also reported its eighth warmest October, at 1.8°C (2.6°F) above normal, with records dating back to 1900

The dot map from page linked to above shows much of central and northern Russia with average temperatures more than 5°C (9°F) above average.

We are told we must keep the global increase within 2°C if life on Earth is not to become rather nasty. Our chances of doing that are zilch.

AIR-POLLUTION WORSENS DROUGHT AND FLOODING

ScienceDaily reports research showing that increases in air pollution and other particulate matter in the atmosphere can strongly affect cloud development in ways that reduce precipitation in dry regions or seasons, while increasing rain, snowfall and the intensity of severe storms in wet regions or seasons.

The study by a University of Maryland-led team of researchers provides the first clear evidence of how aerosols--soot, dust and other small particles in the atmosphere--can affect weather and climate; and the findings have important implications for the availability, management and use of water resources in regions across the United States and around the world, say the researchers and other scientists.

The study found that under very dirty conditions, the mean cloud height of deep convective clouds is more than twice the mean height under crystal-clean air.

'The probability of heavy rain is virtually doubled from clean to dirty conditions, while the chance of light rain is reduced by 50 percent,' says Maryland's Li, who is also affiliated with Beijing Normal University.

AMERICA USED MORE ENERGY IN 2010

ScienceDaily reports that American energy use went back up in 2010 compared to 2009, when consumption was at a 12-year low. The United States used more fossil fuels in 2010 than in 2009, while renewable electricity remained approximately constant, with an increase in wind power offset by a modest decline in hydroelectricity. There also was a significant increase in biomass consumption, according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory.

Though carbon emissions in 2010 were higher than they were in 2009, Americans' carbon footprint has decreased over the past few years. The U.S. emitted 5,632 million metric tons of carbon dioxide in 2010, up from 5,428 in 2009, but down from the all time high of 6,022 in 2007. The decrease is due primarily to reduced energy consumption, aided by a shift from coal to natural gas in the electric sector and adoption of renewable energy resources

ANNUAL GREENHOUSE-GAS INDEX RISING

NOAA's updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many greenhouse gases such as carbon dioxide and methane, shows a continued steady upward trend, reports ScienceDaily.


The AGGI reached 1.29 in 2010, which means that the combined heating effect of long-lived greenhouse gases added to the atmosphere by human activities has increased 29 percent since 1990. That is up from 1.27% in 2009.

He says his research shows the earth's surface temperature has risen by 0.9 degrees Celsius since the 1950s.

EXTREME MELTING OF GREENLAND CAN SELF-AMPLIFY

The Greenland icesheet can experience extreme melting even when temperatures do not hit record highs, according to a new analysis by Dr. Marco Tedesco, assistant professor in the Department of Earth and Atmospheric Sciences at The City College of New York. His findings suggest that glaciers can undergo a self-amplifying cycle of melting and warming that would be hard to stop.

'We are finding that even if you don't have record-breaking highs, as long as warm temperatures persist you can get record-breaking melting because of positive feedback mechanisms,' said Professor Tedesco, who directs CCNY's Cryospheric Processes Laboratory and also serves on CUNY Graduate Centre doctoral faculty.

SEA WILL RISE FOR 500 YEARS?

Researchers from the Niels Bohr Institute are part of a team that has calculated the long-term outlook for rising sea-levels in relation to the emission of greenhouse gases and pollution of the atmosphere using climate models, reports ScienceDaily.

In the pessimistic scenario, emissions keep increasing, and the sea rises 1.1 metres by the year 2100 and 5.5 metres by 2500.

Even in the most optimistic scenario, which requires extremely dramatic climate-change goals, major technological advances and strong international co-operation to stop emitting greenhouse gases and polluting the atmosphere, the sea would rise 60cm by 2100 and 1.8 metres by 2500.

The two more realistic scenarios, based on stablising emissions and pollution, show a sea-level rise of about 75cm by the year 2100 and 2 metres by 2500.

MANMADE AEROSOLS MESSING UP THE MONSOON

This research reported in Science blames human activity for the negative change in the South Asian summer monsoon.

Abstract: 'Observations show that South Asia underwent a widespread summertime drying during the second half of the 20th century, but it is unclear whether this trend was due to natural variations or human activities. We used a series of climate-model experiments to investigate the South Asian monsoon response to natural and anthropogenic forcings. We find that the observed precipitation decrease can be attributed mainly to human-influenced aerosol emissions. The drying is a robust outcome of a slowdown of the tropical meridional overturning circulation, which compensates for the aerosol-induced energy imbalance between the northern and southern hemispheres. These results provide compelling evidence of the prominent role of aerosols in shaping regional climate change over South Asia.'

If current trends continue, a largely ice-free Arctic in the summer months is likely within 30 years. That is up to 40 years earlier than anticipated in the last assessment report by the Intergovernmental Panel on Climate Change (IPCC).

CLIMATE-CHANGE THREATENS AGRICULTURAL PRODUCTION

Science magazine (published by the American Association for the Advancement of Science) has published a study of the global production of the four largest agricultural commodities over the last 30 years: maize, wheat, soybean and rice. Together they account for about 75% of the calories consumed by humans, directly or indirectly.

The study found that maize and wheat have been negatively affected by the rise in global temperatures; rice and soybean have not been affected. Maize production declined 3.8%, wheat 5.5%. The authors conclude that 'climate-changes are already exerting a considerable drag on yield growth', which translates into substantial rises in prices.

CUT THE SOOT TO SLOW WARMING

ScienceDaily reports that a new study of dust-like particles of soot in the air--now emerging as the second most important, but previously overlooked, factor in global warming--provides fresh evidence that reducing soot emissions from diesel engines and other sources could slow melting of sea ice in the Arctic faster and more economically than any other quick fix, a scientist reported in Denver, Colorado on August 31, 2011.

In a presentation at the 242nd National Meeting & Exposition of the American Chemical Society (ACS), Mark Z. Jacobson, Ph.D., cited concerns that continued melting of sea ice above the Arctic Circle will be a tipping-point for Earth's climate, a point of no return. That's because the ice, which reflects sunlight and heat back into space, would give way to darker water that absorbs heat and exacerbates warming. And there is no known way to make the sea refreeze in the short term.

Jacobson's calculations indicate that controlling soot could reduce warming above parts of the Arctic Circle by almost 3 degrees Fahrenheit within 15 years. That would virtually erase all of the warming that has occurred in the Arctic during the last 100 years.

'No other measure could have such an immediate effect,' said Jacobson, who is with Stanford University. 'Soot emissions are second only to carbon-dioxide in promoting global warming, but its effects have been underestimated in previous climate models. Consequently, soot's effect on climate change has not been adequately addressed in national and international global warming legislation. Soot emissions account for about 17 percent of global warming, more than greenhouse gases like methane. Soot's contribution, however, could be reduced by 90 percent in 5-10 years with aggressive national and international policies.'

CLIMATE-CHANGE MAY WIPE OUT A THIRD OF SPECIES

If global warming continues as expected, it is estimated that almost a third of all flora and fauna species worldwide could become extinct. Scientists from the Biodiversity and Climate Research Centre (Biodiversität und Klima Forschungszentrum, BiK-F) and the SENCKENBERG Gesellschaft für Naturkunde discovered that the proportion of actual biodiversity loss should be revised upwards: by 2080, more than 80% of genetic diversity within species may disappear in certain groups of organisms. The study is the first world-wide to quantify the loss of biological diversity on the basis of genetic diversity.

KEY GREENLAND GLACIER MELTING FASTER

A key glacier in Greenland is melting faster than previously expected, according to findings by a team of academics that included Dr Edward Hanna from University of Sheffield's Deaprtment of Geography, Dr Sebastian Mernild from the Los Alamos Laboratory, USA, and Professor Niels Tvis Knudsen from the University of Aarhus, Denmark. The team´s new findings present crucial insight into the effects of climate change.

The researchers found that Greenland's longest-observed glacier, Mittivakkat Glacier, made two consecutive record losses in mass observations for 2010 and 2011.

IRON TO REPLACE PLATINUM IN FUEL-CELLS

A research-team at INRS have now built on their pioneering achievement--the first high-performance iron-based catalyst for fuel-cells. They have developed a new and improved iron-based catalyst that generates even more electric power. Previously, only platinum-based catalysts could produce similar performance.

The team, led by Professor Jean-Pol Dodelet, bolsters the prospect of iron-based catalysts replacing platinum ones. Platinum is rare and very costly; iron is the second most abundant metal on earth and is inexpensive.

'Thanks to this breakthrough we are nearing the day when we will be able to drive electric-electric hybrid vehicles--i.e. battery and fuel-cell powered--which can potentially free us from our current dependence on oil to power our cars,' said Professor Dodelet.

Full story on ScienceDaily.

In the EStarCar the need for the so-called 'electric-electric hybrid' was recognised many years ago--right from the start. That is why it has multiple sources of power, centred on a power-train made up of a fuel-cell, a lithium-polymer battery array and an ultracapacitor array. It also has solar cells in the roof. Its sources of power, both primary (such as the fuel-cell), and secondary, such as the ultracapacitors and regenerative braking, at present total more than a dozen.

'Electric-electric hybrid'! What a silly term! Why not keep things simple and call it an electric car? Otherwise every time another source of power is added we will need to add another '-electric' to the string. Under that silly regime the EStarCar would have to be called 'an electric-electric-electric-electric-electric-electric-electric-electric-electric-electric-electric-electric-electric-electric hybrid'. NO. It is an electric car. An advanced electric car, yes, but an electric car.

SMALL AMOUNT OF WARMING COLLAPSES ICE-SHELVES

An analysis of prehistoric 'Heinrich events' that happened many thousands of years ago, creating mass discharges of icebergs into the North Atlantic Ocean, make it clear that very small amounts of subsurface warming of water can trigger a rapid collapse of ice-shelves. The findings provide historical evidence that warming of water by 3-4 degrees was enough to trigger these huge, episodic discharges of ice from the Laurentide Ice Sheet in what is now Canada, and raise serious concerns about Antarctic ice sheets.

OCEANS SET TO RISE MANY METRES

An analysis of records left by the Last Interglacial led by the University of Arizona has found that most of the 8-metre rise in sea-levels was due to the melting of ice-sheets, not thermal expansion, and that average ocean temperatures then were only 0.7 degrees Celsius above what they are now.

'This means that even small amounts of warming may have committed us to more ice sheet melting than we previously thought. The temperature during that time of high sea levels wasn't that much warmer than it is today,' said Nicholas McKay, a doctoral student at the UA's department of geosciences and the paper's lead author.

McKay pointed out that even if ocean levels rose to similar heights as during the Last Interglacial, they would do so at a rate of up to a metre per century.

'Even though the oceans are absorbing a good deal of the total global warming, the atmosphere is warming faster than the oceans. Moreover, ocean warming is lagging behind the warming of the atmosphere. The melting of large polar ice sheets lags even farther behind. As a result, even if we stopped greenhouse gas emissions right now, the Earth would keep warming, the oceans would keep warming, the ice sheets would keep shrinking, and sea levels would keep rising for a long time.'

Jonathan Overpeck, co-director of the UA's Institute of the Environment and a professor with joint appointments in the department of geosciences and atmospheric sciences, said: 'This study marks the strongest case yet made that humans--by warming the atmosphere and oceans--are pushing the Earth's climate toward the threshold where we will likely be committed to four to six or even more metres of sea level rise in coming centuries.'

Overpeck, who is McKay's doctoral advisor and a co-author of the study, said: 'Unless we dramatically curb global warming, we are in for centuries of sea level rise at a rate of up to three feet per century, with the bulk of the water coming from the melting of the great polar ice sheets--both the Greenland and Antarctic Ice Sheets.'

DRAMATIC CLIMATE SWINGS LIKELY AS WORLD WARMS

Using research into the ancients behaviour of El Niño, scientists at Oxford and Leeds Universities predict that the dramatic climate swings behind both last year's Pakistan flooding and this year's Queensland floods in Australia are likely to continue as the world gets warmer.

They have discovered that the El Niño Southern Oscillation (ENSO), the sloshing of the warmest waters on the planet from the West Pacific towards the East Pacific every 2-7 years, continued during Earth's last great warm period, the Pliocene

The Pliocene (which lasted from 5 to 3 million years ago) had carbon dioxide levels similar to the present day, with global mean temperatures about 2-3ºC higher, so it is a useful test-ground for climate research. Ancient temperatures are derived from analysis of the chemical composition of the shells of small organisms, known as foraminifera, in ocean-floor sediments.

GREEN-ENERGY INVESTMENT UP $211 BILLION IN 2010

World-wide spending in 2010 on renewable energy was up 32% on 2009, with wind-farms in China and small-scale solar panels on rooftops in Europe largely responsible for the increase, according to the latest annual report on renewable energy investment trends issued by the UN Environment Programme (UNEP).

Last year, investors pumped a record $211 billion into renewables, 32% more than the $160 billion invested in 2009, and a 540% rise since 2004.

For the first time, developing economies overtook developed ones in 'financial new investment'--i.e., spending on utility-scale renewable energy projects and provision of equity capital for renewable energy companies. $72 billion was invested in developing countries versus $70 billion in developed economies. That is huge contrast with 2004, when financial new investments in developing countries were about one quarter of those in developed countries.

2010 ONE OF TWO WARMEST YEARS ON RECORD

Globally, 2010 was one of the two warmest years on record, according to the 2010 State of the Climate report, which NOAA has just released. The peer-reviewed report, issued in coordination with the American Meteorological Society, was compiled by 368 scientists from 45 countries. It provides a detailed, yearly update on global climate indicators, notable climate events and other climate information from every continent.

'We're continuing to closely track these indicators because it is quite clear that the climate of the past cannot be assumed to represent the climate of the future. These indicators are vital for understanding and making reliable projections of future climate,' said Thomas R. Karl, L.H.D, director of NOAA's National Climatic Data Center in Asheville, N.C.

FASTEST C02 RELEASE AND HOT SUMMERS

The rate of release of carbon into the atmosphere today is nearly 10 times as fast as during the Paleocene-Eocene Thermal Maximum (PETM), 55.9 million years ago, the best analog we have for current global warming, according to an international team of geologists. Rate matters, and this current rapid change may not allow sufficient time for the biological environment to adjust. Full story at ScienceDaily. Second story on the same subject also at ScienceDaily.

The tropics and much of the Northern Hemisphere are likely to experience an irreversible rise in summer temperatures within the next 20 to 60 years if atmospheric greenhouse gas concentrations continue to increase, according to a new climate study by Stanford University scientists. The Stanford team concluded that many tropical regions in Africa, Asia and South America could see 'the permanent emergence of unprecedented summer heat' in the next two decades. Middle latitudes of Europe, China and North America--including the United States--are likely to undergo extreme summer temperature shifts within 60 years, the researchers found.

REMOVAL OF C02 FROM AIR NOT VIABLE

Technologies for removing carbon dioxide from the atmosphere are unlikely to offer an economically feasible way to slow human-driven climate change for several decades, according to a new report. The American Physical Society has released a new assessment -- Direct Air Capture (DAC) of CO2 with Chemicals -- to better inform the scientific community on the technical aspects of removing carbon dioxide from the atmosphere.

Robert Socolow, a professor of mechanical and aerospace engineering at Princeton University, who served as a co-chair of the DAC study, said, "We humans should not kid ourselves that we can pour all the carbon dioxide we wish into the atmosphere right now and pull it out later at little cost."

ARCTIC MELTING AND RAISING SEA FASTER
A much reduced covering of snow, shorter winter season and thawing tundra: the effects of climate change in the Arctic are already here, and are taking place significantly faster than previously thought--the conclusions of new research report on the Arctic, presented in Copenhagen this week. 'The changes are dramatic, not coincidental; the trends are unequivocal and deviate from the norm.' See ScienceDaily.

On top of that, a new study is projected a rise of up to 1.6 meters in global sea-levels by 2100, due to accelerating climate-change in the Arctic and the melting of Greenland's icecap.

RUSSIAN BOREAL FOREST CHANGING RAPIDLY

A rapid, large-scale change in the type of trees is accelerating in Russia's boreal forest, which spans its cold northern regions, and is the largest continuous expanse of forest in the world.

CO2 RAPIDLY AFFECTS ATMOSPHERIC STRUCTURE

New research reported in ScienceDaily work shows that carbon-dioxide rapidly affects the structure of the atmosphere, causing quick changes precipitation, as well as many other aspects of Earth's climate, well before the greenhouse gas noticeably affects temperature.

‘The direct effects of carbon-dioxide on precipitation take place quickly,’ said a lead researcher. ‘If we could cut carbon-dioxide concentrations now, we would see precipitation increase within the year, but it would take many decades for the climate to cool.’

HYDROGEN FUEL-CELL VEHICLES NOW CLOSER

ScienceDaily outlines a paper published in
Science magazine that reveals a breakthrough in using ammonia borane to store hydrogen that will make it a far more attractive fuel for vehiclesby researchers at the Los Alamos National Laboratory describes a simple scheme that regenerates ammonia borane from a hydrogen-depleted 'spent fuel' form (called polyborazylene) back into a usable fuel via reactions in a single container. That 'one pot' method represents a significant step toward the practical use of hydrogen in vehicles by potentially reducing the expense and complexity of the recycling stage. Regeneration takes place in a sealed pressure-vessel in off-vehicle sites using hydrazine and liquid ammonia at 40 degrees Celsius. The researchers envision vehicles with interchangeable hydrogen storage tanks containing ammonia borane that are used then sent back to a factory for recharging.

ARCTIC OZONE-LEVEL PLUMMETS

Unusually low temperatures in the Arctic's ozone layer have initiated a massive depletion of ozone there recently, and the Arctic seems to be heading for a record loss. At the relevant altitudes about half the ozone that above the Arctic has been destroyed in recent weeks, which may also affect regions further south. Scientists expect further depletion, because the conditions that caused the unusally rapid depletion are continuing. Full report on ScienceDaily.

MELTING ICE-SHEETS DOMINATE RISING SEA

The Greenland and Antarctic ice sheets are losing mass at an accelerating rate, according to a new NASA-funded satellite study, the longest study of changes in polar ice sheet mass. It suggests that they are overtaking the loss from mountain glaciers and ice-caps to become the dominant contributor to global sea-level rise, much sooner than model forecasts have predicted.

In 2006, a year in which comparable results for the loss from mountain glaciers and ice caps are available from a separate study, the Greenland and Antarctic ice-sheets lost a total average of 475 gigatonnes a year, enough to raise global sea-level an average of 1.3 millimeters a year

The pace at which the polar ice sheets are losing mass was found to be accelerating rapidly. Each year over the course of the study, the two ice-sheets lost a combined average of 36.3 gigatonnes more than they had the year before. In comparison, the 2006 study of mountain glaciers and ice caps estimated their loss at 402 gigatonnes a year on average, with an acceleration rate a third that of the ice-sheets.

'That ice-sheets will dominate future sea-level rise is not surprising -- they hold a lot more ice than mountain glaciers,' said lead author Eric Rignot, of NASA's Jet Propulsion Laboratory, Pasadena, California, and the University of California, Irvine. 'What is surprising is this increased contribution by the ice-sheets is already happening. If present trends continue, sea-level is likely to be significantly higher than levels projected by the United Nations Intergovernmental Panel on Climate Change in 2007.'

The authors conclude that if the rate at which the ice-sheets are now melting continues, the world's oceans would be 15 centimetres higher by 2050. When that is added to the predicted contribution of 8cms from glacial ice caps and 9cms from thermal-expansion, the total could reach 32cms.

EXTREME WEATHER LINKED TO CLIMATE-CHANGE

WARMER EARTH EVEN WITH ZERO EMISSIONS

New research by the University of Washington (UW), reported on ScienceDaily, shows that the world is committed to a warmer climate because of emissions that have occurred up to now, regardless of what we do to mitigate the effects.

There would continue to be warming even if the most stringent policy proposals were adopted, because there still would be some emission of heat-trapping greenhouse gases such as carbon dioxide and methane. The new research shows that even if all emissions were stopped now, temperatures would remain higher than levels before the Industrial Revolution in the nineteenth century because the greenhouse gases already emitted will probably persist in the atmosphere for thousands of years.

In fact, temperatures may continue to escalate even if all cars, heating and cooling systems and other sources of greenhouse gases were suddenly eliminated, said Kyle Armour, a UW doctoral student in physics, because tiny atmospheric particles called aerosols, which tend to counteract the effect of greenhouse warming by reflecting sunlight back into space, would last only a matter of weeks once emissions stopped, but the greenhouse gases would continue.

'The aerosols would wash out quickly and then we would see an abrupt rise in temperatures over several decades,' he said.

RISING SEA THREATENS 180 US CITIES

Research led by scientists at the University of Arizona, reported in ScienceDaily, says rising sea-levels caused by climate-change could threaten an average of 9 percent of the land in 180 U.S. coastal cities by 2100. The Gulf and southern Atlantic coasts will be particularly hard-hit. Miami, New Orleans, Tampa, Fla., and Virginia Beach, Va. could lose more than 10 percent. The research is the first analysis of vulnerability to sea-level rise that includes every U.S. coastal city in the lower 48 with a population of 50,000 or more. The latest scientific projections indicate that by 2100 the sea level will rise about 1 metre, or more.

AMAZONIAN DROUGHTS RING ALARM BELLS

The 2010 drought in the Amazon may have been even more devastating for its rainforests than the unusual 2005 drought, which had been billed as a 1-in-100-year event, report ScienceDaily and NewsDaily.

Analyses of rainfall across 5.3 million square kilometres of Amazonia during the 2010 dry season, recently published in Science, shows that the drought was more widespread and severe than the one in 2005. The UK-Brazilian team also calculated that the carbon impact of the 2010 drought may exceed the 5 billion tonnes of CO2 released after the 2005 event, because severe droughts kill trees (to put that in perspective the United States emitted 5.4 billion tonnes of CO2 from fossil fuel use in 2009).

2010 SETS MELT RECORD FOR GREENLAND

2010 set new records for the melting of the Greenland ice-sheet, expected to be a major contributor to projected sea level rises in coming decades, reports ScienceDaily.

'This melt season was exceptional, with melting in some areas up to 50 days longer than average,' said Dr. Marco Tedesco, director of the Cryospheric Processes Laboratory at The City College of New York (CCNY -- CUNY), who is leading a project studying variables that affect the melting of the ice-sheet.

'Melting in 2010 started exceptionally early at the end of April and ended quite late in mid- September.'

The study, with different aspects sponsored by World Wildlife Fund (WWF), the National Science Foundation and NASA, examined surface temperature anomalies over the surface of the ice-sheet, as well as estimates of surface melting from satellite data, ground observations and models.

In 2010, summer temperatures up to 3C above the average were combined with reduced snowfall.

COMPOST BOMB COULD SPEED GLOBAL OVERHEATING

The rate at which the global climate heats could lead to a rapid release of carbon from peatlands that would further accelerate the heating, reports ScienceDaily. Two recent studies published by the Mathematics Research Institute at the University of Exeter highlight the risk that this 'compost bomb' instability could pose, and show that there is a dangerous rate of warming beyond which the instability occurs, which then accelerates climate-change. It is the speed of change that tips the bomb. That contrasts with the general belief that tipping-points correspond to dangerous levels of warming. The researchers are exploring the link with the peat fires round Moscow earlier this year.

NASA FINDS EARTH'S LAKES ARE WARMING

In the first comprehensive global survey of temperature trends in major lakes ( reported on ScienceDaily )NASA researchers have found that Earth's largest lakes have warmed during the past 25 years in response to climate-change. Satellite data was used to measure the surface temperatures of 167 large lakes, which showed an average warming-rate of 0.45 degrees Celsius per decade, with some lakes warming as much as 1 degree Celsius per decade. The trend was global; the greatest increases were in the mid- to high-latitudes of the Northern Hemisphere.

The results have implications for lake ecosystems, which can be adversely affected by even small water temperature changes.

HUMAN EFFECT ON NITROGEN RISKS GLOBAL DAMAGE

An authoritative study published in the October 8 issue of Science magazine (the publication of the American Association for the Advancement of Science) sounds the alarm over what humans are doing to the Earth's nitrogen cycle.

Micro-organisms have been controlling the cycle since life began on the planet. With life evolving around it, nitrogen became both an essential nutrient and a major regulator of climate.

The study in Science (pages 192-196, Vol 330, Oct 8 2010) reviews the major changes there have been to the nitrogen cycle throughout the Earth's history. Most of the time they coincided with the arrival of new organisms that provided new metabolic pathways.

But the last century has seen humans push the biological nitrogen cycle into a very different stage. Adding large amounts of fixed nitrogen in the form of fertiliser chokes out aquatic life that relies on run-off, and significantly increases the amount of NO2 in the atmosphere ( a greenhouse gas 300 times more potent than CO2).

Micro-organisms may one day restore balance in the nitrogen cycle that they helped shape for billions of years, but humans must change their behaviour, or risk causing irreversible changes to life on Earth.

SEVERE DROUGHT MAY BECOME GLOBAL PROBLEM

The United States and many other heavily populated countries face a growing threat of severe and prolonged drought in coming decades, according to a new study by National Center for Atmospheric Research (NCAR) scientist Aiguo Dai, and reported on ScienceDaily.

CARBON-DIOXIDE DRIVES OF GLOBAL TEMPERATURE

Water vapoUr and clouds are the major contributors to Earth's greenhouse effect, but a new atmosphere-ocean climate modeling study by Andrew Lacis and colleagues at NASA's Goddard Institute for Space Studies in New York shows that the planet's temperature ultimately depends on the atmospheric level of carbon dioxide.

The notable feature of the team's study of the nature of Earth's greenhouse effect was to identify the importance of non-condensing greenhouse gases--such as carbon dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons. Without them, water vapour and clouds could not provide the feedback mechanisms that amplify the greenhouse effect. The study's results were published on the 15th of October in Science. The consequence is that carbon-dioxide is responsible for 80% of the greenhouse effect.

BLEAK FUTURE FOR OCEAN LIFE
A unique natural laboratory in the Mediterranean is revealing the effects of rising carbon-dioxide levels on ocean life, and shows a bleak future as ocean acidity rises.

Scientists from the University of Plymouth in England and the University of Santa Catarina in Brazil studied single-celled organisms called Foraminifera round volcanic carbon-dioxide vents off Naples in Italy. The study, published in the September issue of the Journal of the Geological Society, found that increasing CO2 levels caused foram diversity to fall from 24 species to only 4. A tipping-point occurs at mean pH 7.8, the pH level predicted for the end of the century.

NEW TECHNOLOGY BRINGS ELECTRICITY-GENERATION HOME

Reported in ScienceDaily is a new technology aimed at making every household and place of business a generator of electricity. Every point of consumption will also be a point of generation. The energy-base of society will be sunlight and water, not oil and coal. And huge transmission-lines will vanish.

The technology to do all that has been with us for years (the International Space Station runs on it). The new technology makes it much more efficient.

HIGHEST GLOBAL TEMPERATURES CONTINUE.

Data published by America's NOAA Satellite and Information Service, shows that the alarming temperatures continue:

The combined global land and ocean average surface temperature for June 2010 was the warmest on record at 16.2°C (61.1°F), which is 0.68°C (1.22°F) above the 20th century average of 15.5°C (59.9°F). The previous record for June was set in 2005.

June 2010 was the fourth consecutive warmest month on record (March, April, and May 2010 were also the warmest on record). This was the 304th consecutive month with a global temperature above the 20th century average. The last month with below-average temperature was February 1985.

The June worldwide averaged land surface temperature was 1.07°C (1.93°F) above the 20th century average of 13.3°C (55.9°F)—the warmest on record.

It was the warmest April–June (three-month period) on record for the global land and ocean temperature and the land-only temperature. The three-month period was the second warmest for the world's oceans, behind 1998.

It was the warmest June and April–June on record for the Northern Hemisphere as a whole and all land areas of the Northern Hemisphere.

It was the warmest January–June on record for the global land and ocean temperature. The worldwide land on average had its second warmest January–June, behind 2007. The worldwide averaged ocean temperature was the second warmest January–June, behind 1998.

ABOUT 500 BILLION SHOULD DO IT

Scientists at the Carnegie Institution have found that if we removed 100 billion tons of carbon-dioxide from the atmosphere the average global temperature would drop only 0.16 degrees Celsius.

Which means that to reverse the damage we have done to the planet we would have to remove about 500 billion tons.

Even if we knew how to do that it would take many lifetimes.

DIRE IMPACT FROM CHANGES IN OCEANS

The first comprehensive synthesis on the effects of climate change on the world's oceans has found they are now changing at a rate not seen for several million years, reports ScienceDaily.

Professor Ove Hoegh-Guldberg, lead author of the report and Director of The University of Queensland's Global Change Institute, says the findings have enormous implications for mankind, particularly if the trend continues.

He said that the Earth's ocean, which produces half of the oxygen we breathe and absorbs 30% of human-generated CO2, is equivalent to its heart and lungs. "Quite plainly, the Earth cannot do without its ocean. This study, however, shows worrying signs of ill health.

"It's as if the Earth has been smoking two packs of cigarettes a day!"

He warned that we may soon see "sudden, unexpected changes that have serious ramifications for the overall well-being of humans," including the capacity of the planet to support people. "This is further evidence that we are well on the way to the next great extinction event."
