So for Halloween, I dressed as the ghost of Scienceblogs.</div>

I am still working on getting all the old posts copied over here, but it shouldn't take much longer.</div>

Though I think I<br/>should add a rule to the effect that if a numerical claim is wrong by<br/>more than an order of magnitude you get a free square on the bingo<br/>board. Look at what Carter claims:<br/><br/>>Carbon dioxide was a minor greenhouse gas, responsible for 3.6 per<br/>>cent of the total greenhouse effect, [Carter] said. Of this, only 0.12 per<br/>>cent, or 0.036 degrees Celsius, could be attributed to human activity.<br/><br/>Actually, [calculations<br/>show](http://www.realclimate.org/index.php?p=142) that without<br/>CO<sub>2</sub> the Greenhouse effect would be about 91% as strong.<br/>Further, he implies that only 0.12/3.6=3% of the CO<sub>2</sub> in the<br/>atmosphere is due to human activity. But the concentration of<br/>CO<sub>2</sub> in the atmosphere has increased [from 280 ppm to 380<br/>ppm](http://www.grida.no/climate/ipcc_tar/wg1/fig3-2.htm) and this<br/>increase is [all due to human<br/>activity](http://www.realclimate.org/index.php?p=160). So, correcting<br/>Carter's numbers we have that 100/380=25% of the CO<sub>2</sub> in the<br/>atmosphere is anthropogenic, so 25% of 9%=2.4% of the greenhouse<br/>effect or 0.7 degrees Celsius is man-made. Carter is wrong by a<br/>factor of 20. Actually he's wrong by more than a factor of 20 since<br/>his calculation assumes that the quantity of water vapour in the<br/>atmosphere is fixed and this isn't true. As the globe warms there is<br/>more water vapour in the atmosphere and this further strengthens the<br/>greenhouse effect.<br/><br/>So how did something this inaccurate get into the <cite>Age</cite>?<br/>Well, Carter gave a speech to the Victorian Farmers Federation so the<br/>reporter who wrote the story was their agricultural reporter rather<br/>than their science reporter who might have noticed that Carter was<br/>spouting a load of rubbish.<br/><br/>Hat tip: [euan](http://deltoidblog.blogspot.com/2005/06/pearson-claims-that-undersea-volcanoes-cause-global-warming.php#comment-7135)Tim Lamberthttp://www.blogger.com/profile/03619533938771249394noreply@blogger.com15
