Climate Change 2021, the latest report from the Intergovernmental Panel on Climate Change (IPCC), provides a more clear, precise, and dire view of the Earth’s warming climate than the IPCC’s most recent previous assessment in 2013. During that time, multiple lines of evidence have led to improved understanding of human influences on the climate, including weather and climate extremes. Beyond the improved scientific understanding, the warming world and increasing number of extreme weather events have become ever more apparent to us all. The effects are already being felt worldwide.
