Researchers who deal in cold numbers rather than warming climates believe the significant benefits from curbing greenhousegas emissions would justify th outdoor wear canada e costs of action, a new survey finds. Republican senators boycotted a hearing Tuesday over an Environmental Protection Agency analysis about the costs of a cleanenergy bill. In addition, the United States and E outdoor wear canada uropean Union are preparing for a December meeting in Copenhagen to discuss a climate treaty.



An economist tree hugger is an imaginary creature, says Michael Livermore of New York Universitys Institute for Policy Integrity, which conducted the survey. But we found that economists really see climate change poses a lot of risk to the economy.



The survey approached the 289 economists who had published climaterelated studies in the top 25 economics journals in the past 15 years. About half, 144, responded, and 75% agreed or strongly agreed on the value of greenhousegas controls.



In 2006, the British government found that charging industries a fee for greenhousegas emissions would reduce gross domestic product globally about 1% by 2050. economy because of higher health costs, leaving aside climate damage.



Greenhouse gases are transparent to sunlight but retain heat, warming the atmosphere. Industrial greenhousegas emissions have raised global average temperatures about 1.3 degrees Fahrenheit since 1905, according to the Intergovernmental Panel on Climate Change, and will likely increase them from 3 to 7 degrees more by 2100.



Many observers look at economists as skeptics of the need for climate mitigation, says economist Gary Yohe of Wesleyan University in Middletown, Conn. But most accept the unquestionable consensus from the natural scientist that the planet is warming and humans are to blame.



In the survey of economists:



wanted a tax or cap and trade system, where polluters buy and sell emission permits, instead of regulation, to cut greenhouse gases.



agreed the effects of global warming create significant risks to the economy, particularly to agriculture, fishing, insurance and health.



Myron Ebell of the Competitive Enterprise Institute, which opposes limits to greenhouse gases, says the economists polled vastly exaggerate the potential damages and vastly understate the costs of reducing emissions.
