Document Summary
Many observed changes are unprecedented on timescales of millennia. Climate will continue to change in the future. Limiting future climate change will require substantial and sustained emissions reduction. Most aspects of climate change will persist for many centuries even if emissions of.

Contrast between wet and dry regions will increase. Extent of wet and dry seasons will increase overall. Drought projections are inconsistent across the globe. Heat will penetrate from the surface to the deep ocean. Sea level will continue to rise due to water expansion from warming and added volume from glaciers and ice sheets. Arctic sea ice is very likely to continue to shrink and thin. Virtually certain that there will be more frequent hot extremes and less frequent cold extremes.
