This fact has also been explained in <A href="http://motls.blogspot.com/2007/03/great-global-warming-swindle.html">The Great Global Warming Swindle</A>. It follows that the C02 greenhouse effect has not been important in the history and we shouldn't expect that it will become important in the future.</DIV><BR />The direction of the causal relationship can be shown in many ways: for example, it is not just CO2 but other gases such as methane that follow temperature. The hypothesis of CO2 as the primary reason wouldn't explain why these other gases are correlated, too. Also, we understand how oceans react to temperature changes by releasing gases. Finally, the gas concentrations lag behind the temperature by 800 years, see e.g. this 2003 paper in Science by <A rel="nofollow" href="http://icebubbles.ucsd.edu/Publications/CaillonTermIII.pdf">Caillon et al.</A><BR /></P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/F243DDF5-56A8-423D-8AA4-8A654302D3A6/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
