GLOBAL CHANGE:   IPCC Reports

      Every several years, the Intergovernmental Panel on Climate Change (IPCC) conducts a scientific review of global climate change.  The most recent was the Assessment Report #6 which was started prior to the COP26 Climate Summit Meeting in 2021.  This set of reports will soon be finalized.  The reports from AR6 are grouped into three working groups (WG), where WG-I deals with the physical science basis, while WG-II deals with impacts, adaptation, and vulnerability, and WG-III focuses on mitigation of climate change.   We have copies of these reports. Here, on this webpage, they are available for visitors to download, or the visitor can attend the IPCC website directly.  More detail about the oceans is included in a set of reports from 2019, but here, only the ocean report (Special Report on the Ocean and Cryosphere in a Changing Climate) is included.  Finally, the IPCC began developing these periodic assessments in the late 1980’s and the first reports are dated 1990.  These early reports have been included here primarily as a historical record of the thoughts about climate change at that time.
