Climate scientists are puzzled over the possible significance of rising levels of atmospheric carbon dioxide (CO2).
Some think a recent acceleration in CO2 increases could be a sign of imminent, rapid global warming.
But others say the evidence of just two years is inconclusive, and suspect that natural causes are likelier culprits.
The UK government's chief scientific adviser, Sir David King, says the rise appears on the evidence so far to be an aberration, not the start of a trend. Carbon dioxide is the main gas given off by human activities (including the burning of fossil fuels, and deforestation) which scientists believe is exacerbating natural climate change.......http://news.bbc.co.uk/2/hi/science/nature/3732274.stm
