The Working Group I contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report provides a reality check on climate change. We now have a much clearer picture of the past, present and possible future climates, and this information is essential for understanding where we are headed, what can be done, and the multiple facets of a changing climate to prepare for, in every region. Unless deep reductions in greenhouse gas emissions occur in the coming decades, global warming of 1.5°C and 2°C above pre-industrial levels will be exceeded during the 21st century.

The new Working Group I Report structure integrates multiple lines
of scientific evidence within each chapter and provides robust knowledge relevant for policymaking through the end-to-end assessment of key topics. This more holistic approach has resulted in a report that provides a better understanding of the climate system, for both past and future changes, with a new emphasis on climate information for regions, which is critical for informing adaptation and risk management strategies. Today, many decisions remain grounded in the experience of past climate variability.

This report provides a solid basis for taking into account future changes that need to be considered in today’s decisions, with increased relevance for climate services, to enhance adaptation and resilience to climate change and curb greenhouse gas emissions.
