Contribution to IPCC

The ETCCDI has provided direct contribution to the Assessment Reports (ARs) of the Intergovernmental Panel on Climate Change (IPCC). For the Fifth AR (AR5), several members of ETCCDI contributed as Coordinating Lead Authors, Lead Authors and Review Editors for various chapters. The ETCCDI Climate Change Indices are widely used to define and describe climate extremes based on broadly available data over both space and time.
