Moreover, nearly half of Americans (47%) and somewhat fewer Chinese (37%) express little or no concern about the problem." Robert Watson found this "very disappointing" and said "We need the public to understand that climate change is serious so they will change their habits and help us move towards a low carbon economy." A 2012 Canadian poll, found that 32% of Canadians said they believe climate change is happening because of human activity, while 54% said they believe it's because of human activity and partially due to natural climate variation.Tags: Writing The Tok EssayImpact Of The Renaissance EssayGeography Dissertation ExamplesEssay About Effective TeacherQuotes Included Word Count DissertationEffect Of Media On Society EssayEssay On Crucible John ProctorNonprofit Business Plan Template WordInsurance Law Essay
All countries of the European Union ratified the 1997 Kyoto Protocol. The United States Energy Information Administration reports that, in the United States, "The 2012 downturn means that emissions are at their lowest level since 1994 and over 12% below the recent 2007 peak." The theory that increases in greenhouse gases would lead to an increase in temperature was first proposed by the Swedish chemist Svante Arrhenius in 1896, but climate change did not arise as a political issue until the 1990s.
It took many years for this particular issue to attract any type of attention.
At the same time environmental organizations and the political opposition were demanding "solutions that contrasted with the government's".
In May 2013 Charles, Prince of Wales took a strong stance criticising both climate change deniers and corporate lobbyists by likening the Earth to a dying patient.
Disputes over the key scientific facts of global warming are more prevalent in the media than in the scientific literature, where such issues are treated as resolved, and such disputes are more prevalent in the United States than globally.
Political and popular debate concerning the existence and cause of global warming includes the reasons for the increase seen in the instrumental temperature record, whether the warming trend exceeds normal climatic variations, and whether human activities have contributed significantly to it.
A 15-nation poll conducted in 2006, by Pew Global found that there "is a substantial gap in concern over global warming—roughly two-thirds of Japanese (66%) and Indians (65%) say they personally worry a great deal about global warming.
Roughly half of the populations of Spain (51%) and France (46%) also express great concern over global warming, based on those who have heard about the issue.
Scientists have resolved these questions decisively in favour of the view that the current warming trend exists and is ongoing, that human activity is the cause, and that it is without precedent in at least 2000 years.
Public disputes that also reflect scientific debate include estimates of how responsive the climate system might be to any given level of greenhouse gases (climate sensitivity), how the climate will change at local and regional scales, and what the consequences of global warming will be.
