Document Summary
The global mean surface temperature change for the period 2016 2035 relative to. 1986 2005 is similar for the four rcps, and will likely be in the range 0. 3 c to 0. 7 c (medium confidence). It is virtually certain that there will be more frequent hot and fewer cold temperature extremes. It is very likely that heat waves will occur with a higher frequency and longer duration. Occasional cold winter extremes will continue to occur. Changes in precipitation in a warming world will not be uniform. High latitudes and the equatorial pacific are likely to experience an increase in annual mean precipitation by the end of this century under the rcp8. 5 scenario. Mid-latitude and subtropical dry regions, mean precipitation will likely decrease. Extreme precipitation events over most mid-latitude land masses and over wet tropical regions will very likely become more intense and more frequent as global mean surface temperature increases.
