Climate Change
¥The earth has warmed an
average 0.6¡C (1.0¡F) since 1970
¥Rising temperatures fuel
stronger storms and increase crop-withering heat waves
¥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
For every 1¡C rise in temperature above the norm during the growing season, yields of wheat, rice, and corn
drop 10 percent.Photo Credit: iStockPhoto /
