Cap-and-Cry: California's Global Warming Program (avoided warming of 0.005°C by 2050 under CARB regulations)

By Chip Knappenberger -- November 3, 2011

“… the total is 0.00476°C (0.0086°F) of global warming avoided by the California cap-and-trade program for reducing greenhouse gas emissions out to the year 2050. Such numbers strain the limits of detectability within our current observing systems, not to mention environmental significance.”

With the California Air Resource Board’s (CARB) recent announcement that they have finalized their greenhouse gas cap and trade regulations, California becomes the first state to have, according to the CARB’s chairperson Mary Nichols, “done something important” on the issue of climate change.

Ms. Nichols couldn’t be further from the truth. While CARB may have done “something important” for many things in California (not all of which may prove positive), climate change isn’t one of them.

If the emissions targets under the CARB cap and trade program as it is scheduled to the year 2020 are met, the total amount of global temperature rise that would be avoided amounts to 0.00015°C (or for those who prefer English units, 0.00027°F).
