Climate Change
¥The Intergovernmental Panel on
Climate Change (IPCC) projects earthÕs average temperature will rise 1.1 - 6.4¡C
(2.0 - 11.5¡F) during this century
¥Current trajectory is already
outpacing projections
¥As temperatures rise, glaciers
and ice sheets melt, causing sea level to rise
¥Extreme weather events, such
as crop-withering heat waves, droughts, and powerful storms become more frequent and more intense
¥For every 1¡C rise in
temperature above the optimum during the growing season, yields of wheat, rice, and corn drop 10 percent.
