Thermometer Americans Lose Interest in Global WarmingEven though recently 18 scientific organizations wrote Congress to reaffirm the consensus behind global warming and a federal government report found that global warming is upsetting the Arctic’s thermostat, a new poll says that just 57 percent of Americans think there is solid evidence the world is getting warmer, down 20 points in just three years.

A new Pew Research Center for the People & the Press  poll shows the number of people saying there is strong scientific evidence that the Earth has gotten warmer over the past few decades is down from 71 percent in April of last year and from 77 percent when Pew started asking the question in 2006. The number of people who see the situation as a serious problem also has declined.

Also, the share of people in the U.S. who believe that pollution caused by humans is causing temperatures to rise has also gotten lower, even as the world gears up for possible action against climate change.

The steepest drop has occurred this year, as Congress and the Obama administration have taken steps to control heat-trapping emissions for the first time and international negotiations for a new treaty to slow global warming have gotten under way. All this in view of mounting scientific evidence of climate change – from melting ice caps to the world’s oceans hitting the highest monthly recorded temperatures this summer.

The opinions appear to be strongly related to political, rather than scientific views, which doesn’t surprise us one bit. According to the poll, three-quarters of Democrats believe the evidence of a warming planet is solid, and nearly half believe that the problem is serious, far fewer conservative and moderate Democrats see the problem as severe. At the same time, 57 percent of Republicans say there is no solid evidence of global warming, up from 31 percent in early 2007. It appears that the climate deniers are just as staunchly sticking to their guns as in the case of health-care reform.

In general it seems that priority that people give to pollution and environmental concerns and a whole host of other issues is down because of the state of the economy and because of the focus on other things. The relentless lobbying efforts by the industry appear to have convinced quite a few gullible citizens, even though with some exceptions the vast majority of scientists agree that global warming is occurring and that the primary cause is a buildup of greenhouse gases in the atmosphere from the burning of fossil fuels, such as oil and coal.

That said: despite misgivings about the science, half the respondents still say that they support limits on greenhouse gases, even if they could lead to higher energy prices. And 56 percent of Americans feel the United States should join other countries in setting standards to address global climate change.
