Projected Precipitation
q Based on global model simulations and for a wide range of
scenarios, global average water vapor concentration and
precipitation are projected to increase during the 21st
century.
q By the second half of the 21st century, it is likely that
precipitation will have increased over northern mid- to
high latitudes and Antarctica in winter.
q At low latitudes there are both regional increases and
decreases over land areas.
q Larger year to year variations in precipitation are very
likely over most areas where an increase in mean
precipitation is projected.
