UN’s IPCC Report Finds Climate Change Intensifying

The Intergovernmental Panel on Climate Change (IPCC) recently released the document “Climate Change 2021: The Physical Science Basis“, the Working Group I contribution to the Sixth Assessment Report (AR6.) The report finds that climate change is widespread, rapid, and intensifying.

Founded in 1988, the IPCC is the United Nations body for assessing the science related to climate change. The IPCC prepares comprehensive Assessment Reports about the state of scientific, technical and socio-economic knowledge on climate change, its impacts and future risks, and options for reducing the rate at which climate change is taking place. The IPCC also produces Special Reports on specific topics agreed by its member governments, as well as Methodology Reports that provide practical guidelines for the preparation of greenhouse gas inventories.

This latest report, produced by 234 authors from 65 countries, provides an alarming view on the current “state of the climate, including how it is changing and the role of human influence, the state of knowledge about possible climate futures, climate information relevant to regions and sectors, and limiting human-induced climate change.”

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.

In response to the release of this report, the White House convened the fifth National Climate Task Force meeting to discuss IPCC report findings and President Biden’s entire Build Back Better agenda. White House officials acknowledged that “Americans are already feeling the effects of climate change – from devastating wildfires to extreme heat to a historic drought – and the IPCC report reminds us that we must act swiftly and decisively to reduce greenhouse gas emissions.”
