Here is a Nasa revision of hotest years on record over the last 100 or so. You don't need to be a scientist to look at those numbers and do an analysis which even questions whether there is global warming of any consequence at all.
According to the new data published by NASA, 1998 is no longer the hottest year ever. 1934 is.
Four of the top 10 years of US CONUS high temperature deviations are now from the 1930s: 1934, 1931, 1938 and 1939, while only 3 of the top 10 are from the last 10 years (1998, 2006, 1999). Several years (2000, 2002, 2003, 2004) fell well down the leaderboard, behind even 1900. (World rankings of temperature are calculated separately.)

Then here is a listing of scientists with super-impressive credentials who once believed in anthropomorphic global warming, who have changed their mind due to further research.
The most important point to be made of all this has nothing to do with global warming or cooling or whether man has anything to do with it. The other reasons for encouraging science and markets to dramatically increase efficiencies in energy use, and to find alternative energy sources are far more compelling, provable, and immediate.
1. Middle East and Northern Coast of South America use of oil as weapon.
2. Cost of chasing ever more difficult to reach carbon based resources
3. Pollution of air and other natural rescources by current methods of extraction, delivery, and use of carbon based fuel.
4. Just makes good sense to minimize all costs of energy, freeing up capital and income for other uses.
