IPCC Working Group I

The IPCC Working Group I is one of the three groups of the Intergovernmental Panel on Climate Change (IPCC), which is a global body that assesses climate science. Working Group I focuses specifically on the physical science basis of climate change, examining the latest research on climate systems, greenhouse gas emissions, and observed changes in climate. Its reports provide detailed scientific evidence about how human activities are driving climate change and its impacts on the environment. Policymakers and the public use these findings to understand climate risks and develop strategies for mitigation and adaptation.
