This third recent analysis confirms what our site reported here, and what the MasterResource blog reported based on their analysis last week. The conclusions: Fundamentally, that if the U.S. could reduce CO2 emissions to zero, the impact on global temperatures of that reduction will be negligible (barely measurable) by years 2050 and 2100. Literally, we can throw trillions of dollars down the CO2-reduction rat hole and gain absolutely nothing in return. This is especially true considering China's incredible growth of CO2 emissions.
Below is this most recent analysis, by U.S. state, even. (For a better view of the below table, download this PDF and find this table on page 22.)
