A 2014 report by Ipsos Mori, a marketing firm, found that the United States is the country that is, by a good margin, the country where people are most likely to disagree with the statement, "The climate change we are currently seeing is largely the result of human activity." The countries that are runners-up are the UK and Australia.
Plenty of other world countries have disagreements over the best way to tackle climate change -- there are arguments as to whether the burden should fall mostly on the developed world rather than the developing world, there are arguments over whether we should toy with climate engineering or not, and there are arguments over whether we should focus on renewable energy rather than clean-but-potentially-still-dangerous nuclear energy.
But most countries are no longer entertaining the debate as to whether or not man-made climate change is real. Most countries accepted that fact long ago. But the Republican Party in the United States remains one of the last true bastions in the world of climate denial. matadornetwork.com
