The Working Group I contribution to the IPCC’s Fifth Assessment Report (AR5) considers new

evidence of climate change based on many independent scientific analyses from observations of

the climate system, paleoclimate archives, theoretical studies of climate processes and simulations

using climate models. It builds upon the Working Group I contribution to the IPCC’s Fourth

Assessment Report (AR4), and incorporates subsequent new findings of research. As a

component of the fifth assessment cycle, the IPCC Special Report on Managing the Risks of

Extreme Events to Advance Climate Change Adaptation (SREX) is an important basis for

information on changing weather and climate extremes.
