He is also a man who formerly believed that carbon dioxide emissions were about to cause an ecological calamity via anthropogenic (man-caused) global warming, but he has looked at the evidence and has rethought his former fears. He concludes an article at The Financial Post with this observation:
Even if we stopped emitting all carbon dioxide tomorrow, completely shut up shop and went back to the Stone Age, according to the official government climate models it would be cooler in 2050 by about 0.015 degrees. But their models exaggerate 10-fold — in fact our sacrifices would make the planet in 2050 a mere 0.0015 degrees cooler!He explains the reasons for his conversion from alarmist to skeptic in the rest of the article. According to Evans there's no reliable evidence that global warming is occurring and the belief that it is is based on a false assumption about how the atmosphere handles water vapor and sloppy temperature measurements.
It's an informative piece. If you're interested in the issue and/or concerned about President Obama's plans to curtail greenhouse gas emissions through green energy and cap and trade, you should certainly read it.
