Vermont Senator and Presidential candidate Bernie Sandersresponded to a GOP debate question about the candidate’sgreatest weaknesses by Tweeting:

Sanders advocated fighting global warming through PresidentObama’s Clean Power Plan, but according to analysis by thelibertarian Cato Institute, using models created by theEnvironmental Protection Agency, the plan would only advert only0.019° Celsius of warming by the year 2100, an amount so small that it couldn’t bedetected.

The Clean Power Plan is expected to cost a staggering $41 billion annually.

Sen. Sanders and other Democrats have longclaimed that the United States must “lead by example” on globalwarming as, mathematically, American CO2 reduction schemes arefutile, if China and India keep increasing their carbondioxide emissions.

The world’s largest emitter ofcarbon dioxide has been China since 2006, with Indiaaccounting for the largest share of global emissionsgrowth. According to a 2014 study by the European Union, China emits29 percent of the world’s carbon dioxide, whilethe US is only responsible for 15 percent of theworld’s emissions (the European Union itselfonly accounts for 10 percent and India accounts for another 6percent).

India has expressed disappointment in the draft text ofthe U.N. Climate Change Conference in Paris.Their climate change minister said he was“not at all happy†with the draft forreasons of “equity.†An estimated 400 millionIndians — 31 percent of thepopulation — lack access to electricity, so the country isreluctant to adopt any policy which could slow down growth.
