¥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
