WE ARE ADDING CO2 14000 TIMES FASTER
Research on bubbles of ancient atmospheres in Antarctic ice shows that we are adding carbon-dioxide to the atmosphere 14,000 times faster than natural processes, throwing the global system so far out of equilibrium that it will not recover for hundreds of thousands of years.

The BBC's report has a simpler presentation of the same information with a slightly different emphasis.

19 BILLION TONS MORE CO2 ADDED IN 2007
Last year saw the third biggest increase in global carbon-dioxide since record-keeping began. Annother 19 billion tons poured into the air. There was also a surge in the amount of methane. 27 million tons were added after nearly a decade with little or no increase.
The concentration of carbon-dioxide reached 385 parts per million at the end of the year.

GREENLAND MELTWATER CAN CRACK ICECAP
Scientists from Woods Hole Oceanographic Institute and the University of Washington have for the first time documented the sudden and complete drainage of meltwater from the surface of the Greenland icecap, and found that it can crack the cap all the way to the bottom. The consequent lubricating effect can increase the horizontal flow 50 to 100 percent.

JET-STREAM CHANGES MAY BOOST HURRICANES
The jet-streams are changing in ways that fit global-overheating models. They have risen, and shifted toward the poles. One consequence may be an increase in the frequency and intensity of hurricanes, because jet-streams tend to inhibit their development, so the storms may become more powerful and more frequent as the jet-streams move away from the sub-tropical zones where they are born.

ANOTHER STUDY PREDICTS BIG SEA RISE
A new study presented at a major scientific conference in Vienna predicts that sea-levels could be a metre and a half higher by 2100 says a BBC News report.
That is much more than what the Intergovernmental Panel on Climate Change (IPCC) forecast in its assessment of climate science last year.
