The primary global authority on climate change is the Intergovernmental Panel on Climate Change (IPCC), operating under the United Nations. Scientists within the IPCC gather findings from climate research worldwide, evaluate all collected data together, and draw conclusions from them. The number of monitored publications is truly vast, numbering in the tens of thousands. The reports they regularly publish are thus based on all the information currently available to humanity. Therefore, the conclusions from the IPCC are highly reliable and accurate.
IPCC Assessment Reports
The findings of the IPCC are published at regular intervals in the form of so-called assessment reports. During 2021 and 2022, the 6th assessment report was progressively released. It consists of three parts, each prepared by a different working group (WG). The topic of WG1 is the physical scientific basis of climate change, forming the foundation of information and findings on which the other working groups build. WG2 focuses on the impacts of climate change, adaptation, and vulnerability, examining and forecasting the effects of various climate phenomena on the environment and specific sectors of human activity worldwide. WG3 deals with the mitigation of climate change, which involves reducing the amount of greenhouse gases (GHG) emitted and their potential removal from the atmosphere. Since March 2023, a shorter and more comprehensive synthesis report of the findings from all three working groups has also been available.
