Another Twist in the Tale - Climate Change, my foot, say some!

The papers and the internet is full of talk about Climate Change and Global Warming and Copenhagen Summit... everybody claims to be in the know... this has ceased to be a topic of discussion with the highbrow intellectuals and is now part of kitty parties, page 3 people to college kids to office and college canteens.

Given this overdose on the subject, I read a very interesting article that rubbishes most climate change theories. A group of Scientists from University of Bristol, UK, have a very different story to tell, based on their findings from measurements and statistical data, including historical records extracted from Antarctic ice, and does not rely on computations with complex climate models. Their data shows that the balance between airborne and absorbed Carbon dioxide has stayed approximately constant since 1850, despite emissions of CO2 having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now. This data suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected. They have published these findings in Geophysical Research Letters this month.

Given these new findings, it will be interesting to see how the discussions turn out in Copenhagen, as carbon sink is one of the key points of discussion at the Summit.
