Thrawn, I won't deny that there is a recent pattern of increasing temperatures and CO2 concentration. That's been well established.
The link between the two has been less well-established.
Really?
"What Are Greenhouse Gases?
Some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally occuring greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases:
Carbon dioxide is released to the atmosphere when solid waste, fossil fuels (oil, natural gas, and coal), and wood and wood products are burned.
Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from the decomposition of organic wastes in municipal solid waste landfills, and the raising of livestock.
Nitrous oxide is emitted during agricultural and industrial activities, as well as during combustion of solid waste and fossil fuels.
Very powerful greenhouse gases that are not naturally occurring include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which are generated in a variety of industrial processes.
Each greenhouse gas differs in its ability to absorb heat in the atmosphere. HFCs and PFCs are the most heat-absorbent. Methane traps over 21 times more heat per molecule than carbon dioxide, and nitrous oxide absorbs 270 times more heat per molecule than carbon dioxide. Often, estimates of greenhouse gas emissions are presented in units of millions of metric tons of carbon equivalents (MMTCE), which weights each gas by its GWP value, or Global Warming Potential.
For more on greenhouse gases and global warming potential, see:
Greenhouse Gases and Global Warming Potential Values, Excerpt from the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2000 (82k pdf) U.S. Environmental Protection Agency, Office of Atmospheric Programs, April 2002.
This excerpt describes the characteristics of each of the various greenhouse gases and discusses the concept of Global Warming Potential (GWP) values. Both direct and indirect greenhouse gases are addressed. A detailed comparison of GWP values from the IPCC's Second Assessment Report (SAR) and Third Assessment Report (TAR) is also made, including the effect of a change in GWP values on U.S. greenhouse gas emission trends. Overall, revisions to GWP values do not have a significant effect on U.S. emission trends."

The only sure thing is that it will cripple the global economy.
With global warming, anything is better than nothing.
