New IPCC Report Strengthens Certainty of Climate Change. The new climate report largely reaffirms scientists’ claims. - The latest report from the U.N.’s Intergovernmental Panel on Climate Change says that scientists are more certain than ever that humans are causing global warming, and that climate change will get worse if greenhouse gas levels continue to rise. The report is influential with policymakers because it represents the consensus of hundreds of scientists who have worked for years to draw conclusions from the scientific research on climate change.
