President Barack Obama’s Energy Secretary, Steven Chu, recently declared that legally limiting carbon dioxide emissions would greatly reduce global warming.  But would it really?  Well not according to Lord Christopher Monckton, a former adviser to British Prime Minister Margaret Thatcher, who has recently been  touring the U.S. taking issue with many of the claims of global warming advocates.  Comments Monckton : “Warming caused by carbon dioxide emissions is miniscule at best.  In order to forestall just one degree Fahrenheit of warming the entire world would need to forego all carbon emissions for more than 200 years. Reduction of emission will cause practically no change. Man isn’t to blame.”
