List of scientists opposing the mainstream scientific assessment of global warmingFrom Wikipedia, the free encyclopedia This is an incomplete list, which may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries. A majority of earth and climate scientists are convinced by the evidence that humans are significantly contributing to global warming.[1][2] This is a list of notable scientists who have made statements that conflict with the mainstream scientific understanding of global warming as summarized by the Intergovernmental Panel on Climate Change and endorsed by other scientific bodies. Establishing the mainstream scientific assessment, climate scientists agree that the global average surface temperature has risen over the last century. The scientific consensus and scientific opinion on climate change were summarized in the 2001Third Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). The main conclusions on global warming were as follows:
Listing criteria: The notable scientists listed in this article have made statements since the publication of the Third Assessment Report which disagree with one or more of these 3 main conclusions. Each scientist included in this list has published at least one peer-reviewed article in the broad field of natural sciences, although not necessarily in a field relevant to climatology. To be included on this list it is not enough for a scientist to be merely included on a petition, survey, or list. Instead, the scientist must make their own statement. Contents [hide]
Peer reviewAs of August 2012, fewer than 10 of the statements in the references for this list are part of the peer-reviewed scientific literature. The rest are statements from other sources such as interviews, opinion pieces, online essays and presentations. Academic papers almost never reject the view that human impacts have contributed to climate change. In 2004, a review of published abstracts from 928 peer-reviewed papers addressing "global climate change" found that none of them disputed the IPCC's conclusion that "Earth's climate is being affected by human activities" and that "most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations"[8] A 2013 survey of 3984 abstracts from peer-reviewed papers published between 1991 and 2011 that expressed an opinion on anthropogenic global warmingfound that 97.1% agreed that climate change is caused by human activity.[9] (see also Scientific opinion on climate change and Surveys of scientists' views on climate change). Scientists questioning the accuracy of IPCC climate projectionsScientists in this section have made comments that it is not possible to project global climate accurately enough to justify the ranges projected for temperature and sea-level rise over the next century. They may not conclude specifically that the current IPCC projections are either too high or too low, but that the projections are likely to be inaccurate due to inadequacies of current global climate modeling.
Graph showing the ability with which aglobal climate model is able to reconstruct the historical temperature record, and the degree to which those temperature changes can be decomposed into various forcing factors. It shows the effects of five forcing factors: greenhouse gases, man-madesulfate emissions, solar variability, ozonechanges, and volcanic emissions.[21] Scientists in this section have made comments that the observed warming is more likely attributable to natural causes than to human activities. Their views on climate change are usually described in more detail in their biographical articles.
