Reports from the are the most reviewed and widely accepted information we have on climate change.

The IPCC is an agency of the United Nations.  It was established in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), and has the endorsement of the UN General Assembly.  The IPCC provides leaders across the world with scientific assessments about climate change -- what has taken place and what trends are projected for the future.  

A major report was issued by the IPCC in October, 2018,  which warned that urgent actions are needed to keep global average temperatures from heating up more than 1½ degrees Celcius.  (The Celsius temperature scale is named after Swedish astronomer Anders Celsius [1701–1744].  It has 0°as the freezing point of water and 100° as the boiling point of water.)

The IPCC warns that if average global temperatures rise more than 1.5° C, there will be dangerously higher risks of drought, floods, and other extreme weather that will cause severe problems for people and the planet.
