Quote from University of Bristol research (<a href="http://www.bris.ac.uk/news/2009/6649.html" rel="nofollow">http://www.bris.ac.uk/news/2009/6649.html</a>):<p><i>New data show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now.</i><p><i>This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected.</i><p>No-one is denying that concentrations are rising, the Modelling of these processes is being questioned. Also I don't doubt the need for <i>well thought action</i>. In the 70's-80's similar lobbies killed nuclear energy which is one of the cleanest means of generating energy. Since hydrocarbons will one day run out, we should be spending more money towards this. Granted a portion can be generated with solar and wind, but solar or wind on its own cannot provide the current or projected needs.
