The very first finding in the United Nations Intergovernmental Panel on Climate Change (UNIPCC, or simply, IPCC) August 9 report is this:

“It is unequivocal that human influence has warmed the atmosphere, ocean and land. Widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphere have occurred.”

I strongly suspect that this is the first time the word “unequivocal” has appeared in an IPCC report, given the IPPC’s “calibrated language” and the fact that these reports require both scientific and political consensus. Artist Alisa Singer illustrated one thread of the evidence for human-caused climate change.
