Intergovernmental Panel on Climate Change

Established in 1988, the Intergovernmental Panel on Climate Change (IPCC) is the leading authority on climate change knowledge, and is dedicated to providing objective, scientific information relevant to understanding the scientific basis and risks of climate change. If you are looking for reliable summaries of published, peer-reviewed literature on climate change to inform your strategy and decision-making, this is an excellent place to start. The IPCC's newly released Synthesis Report is the fourth and final instalment of the Sixth Assessment Report (6AR). It summarises the first three sections of the 6AR, which explained the physical science of the climate crisis, including observations and projections of global heating; the impacts of the climate crisis and how to adapt to them; and ways of reducing greenhouse gas emissions. The Synthesis Report makes it clear that time has run out for incremental action - humanity must respond with swift and significant action to avoid the worst impacts of increasingly extreme heatwaves, droughts, flooding, and other crisis conditions.

The IPCC also produces Special Reports, which assess specific issues, and Methodology Reports, which provide practical guidelines for the preparation of greenhouse gas (GHG) inventories.
