In 2013, the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report concluded:
“It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century.”
United States National Research Council, while supporting the Science of Climate Change:
“… there is a strong, credible body of evidence, based on multiple lines of research, documenting that climate is changing and that these changes are in large part caused by human activities. While much remains to be learned, the core phenomenon, scientific questions, and hypotheses have been examined thoroughly and have stood firm in the face of serious scientific debate and careful evaluation of alternative explanations.”
