The Obama administration recently unveiled regulations further limiting carbon dioxide emissions from power plants, and some climate scientists are criticizing the rules for doing virtually nothing to reduce global temperature rises — the whole point of reducing CO2.
“Well the one thing you don’t hear President [Barack] Obama mention is how much his proposed emissions reductions will reduce global warming,” wrote  Dr. Judith Curry, a climatologist at Georgia Tech. “It has been estimated that the U.S. [climate plan] of 28% emissions reduction by 2025 will prevent 0.03 [degrees Celsius] in warming by 2100.”
“And these estimates assume that climate model projections are correct,” Curry wrote, “if the climate models are over-sensitive to CO2, the amount of warming prevented will be even smaller.”
The EPA’s so-called Clean Power Plan aims to reduce emissions 32 percent below 2005 levels by 2030. The EPA has touted billions of dollars in public health and nebulous “climate benefits,” but avoids mention of the rule’s impact on global temperatures.
The EPA, however, argues the Clean Power Plan alone is not meant to address global warming, but instead they say rule will galvanize global support for an international agreement to cut CO2 emissions.
“Trying to sell this plan as economic and public health issue is a ploy to develop political will for President Obama’s preferred energy policies,” Curry wrote. (my emphasis)
