1. IPCC released the report "Climate Change 2021: The Physical Science Basis," pointing out unprecedented changes in the climate
Last August, the Intergovernmental Panel on Climate Change (IPCC) released its Working Group I report, titled "Climate Change 2021: The Physical Science Basis."
According to the report, many of the changes observed in the climate are unprecedented in thousands, if not hundreds of thousands of years, and some of the changes already set in motion — such as continued sea level rise — are irreversible over hundreds to thousands of years.
