LOOK MA! FUEL-CELLS WITHOUT PLATINUM?
If the researchers are right who have managed to 'wire up' using carbon nanotubes the bacterial enzymes called hydrogenases, they will be able to build fuel-cells without platinum, because the hydrogenases will do the catalysis. That would cut the cost of making and maintaining fuel-cells. Click here for the report in ScienceDaily.

OCEANS COULD BE USED TO SLURP UP CO2?
American researchers have proposed a method, reported in Science Daily, of using and enhancing the ocean's absorption of carbon-dioxide by building many hundreds of water-treatment plants round the world. They would extract hydrochloric acid from seawater, which would be neutralised with rock. That would make the oceans more alkaline, enhancing their ability to soak up more CO2. They say 700 plants would offset all our carbon-dioxide emissions.

IPCC SAYS WE ARE KILLING THE PLANET
The fourth IPCC assessment this year says global 'warming' is unequivocal and could cause irreversible damage to the planet.
Click here for Science Daily's report, the New Zealand Herald's, and the BBC's. The BBC site has a link to the full 9.3MB report.
A sea-level rise of up to 1.4 metres is predicted. The IPCC says some of what it formerly predicted for 2020-2030 is happening now.
It is about time we called the situation, officially, what it really is: global over-heating. And admitted that it is far worse than the politicised IPCC reports would have us believe. They are bad enough. The reality is dire.
But don't worry. There's a spare planet in the cupboard.

HOW TO REMOVE CO2 FROM THE ATMOSPHERE?
American researchers say they have found a way of accelerating a natural weathering process that can remove the surplus carbon-dioxide from the atmosphere in only decades. The full report is in

PLANTS' EXTINCTION COULD HALVE PRODUCTIVITY
Science Daily reports on a study showing that the steady extinction of plant species could halve the productivity of natural habitats, affecting all humanity.

MICROSCOPIC PLASTIC THREATENS SEA-LIFE
Science Daily reports a British study showing that the microscropic particles of plastic that litter marine environments may pose a previously unrecognised threat to marine animals by attracting, holding and transporting pollutants such as PCBs. They have been found at the bottom of the foodchain, so their effect would be magnified further up.

ARCTIC MELTDOWN DECADES AHEAD OF MODELS
Science Daily reports that the 'reduction in the sea ice extent has been much faster than global climate models predict. According to Douglas Bancroft, Director of the Canadian Ice Service, the record reduction in 2007 stunned the international operational ice charting community: "The overall extent was similar to what some of the models envisioned but decades in advance of when they expected that would occur. In fact, the summer of 2007 looked very similar to some climate-model forecasts for 2030 to 2050." '
