Document Summary
Ipcc ar5 2013: global surface temperature change for the end of the 21st century is likely to exceed 1. 5 c relative to 1850 to 1900 for all rcp scenarios except rcp2. 6. The contrast in precipitation between wet and dry regions and between wet and dry seasons will increase, although there may be regional exceptions: the global ocean will continue to warm during the 21st century. Heat will penetrate from the surface to the deep ocean and affect ocean circulation. It is very likely that the arctic sea ice cover will continue to shrink and thin and that northern. Hemisphere spring snow cover will decrease during the 21st century as global mean surface temperature rises. Global mean sea level will continue to rise during the 21st century. Further uptake of carbon by the ocean will increase ocean acidification: cumulative emissions of co2 largely determine global mean surface warming by the late 21st century and beyond.
