US Congressman Lamar Smith has written a piece on climate that should be compulsory reading. But for those without the time even to read his piece, let me summarise the bullet points:
1 For 18 years, while atmospheric CO2 levels have increased, global surface temperatures have been flat, in defiance of the IPCC theory of Anthropogenic Global Warming (AGW).
2 US CO2 emissions have reduced 9% since 2005. This was the result of market forces and new technology – not climate policy
3 In the last 1000 years, natural cyclical variation has seen temperatures both higher and lower than today’s. There is nothing exceptional to explain.
4 In the US, Obama’s environmental plans would cost billions of dollars, yet are projected to reduce global temperatures by only 0.01oC
5 Extreme weather: Even the IPCC admits that there is little or no link between climate change and extreme weather events.
6 Population growth (+ two billion by 2050) will lead to major increases in CO2 emissions, swamping the effect of our very expensive climate policies
7 Atmospheric CO2 amounts to only 0.038% of the atmosphere, and human activity contributes on 3% of that. Man-made emissions are essentially trivial.
