Abstract

In October 2018, the Intergovernmental Panel on Climate Change released the Special Report on Global Warming of 1.5°C, describing the expected impacts of 1.5°C and 2°C of warming and outlining global greenhouse gas emission reduction pathways that could limit warming to those levels.

This brief summarizes the Special Report (SR15) and related consequences for Washington state. It addresses these questions:

  • How much warming has already occurred, compared to the 1.5°C threshold?
  • What are the anticipated global consequences of additional warming?
  • What are the implications for Washington state?
  • How much more warming is likely to occur, given current emissions patterns and policies?
  • What are the options for limiting warming to 1.5°C or 2°C?
