The Center for Global Food Issues sing the praises of higher CO2 levels and say, ". . . a warmer planet has beneficial effects on food production. It results in longer growing seasons-more sunshine and rainfall-while summertime high temperatures change little. And a warmer planet means milder winters and fewer crop-killing frosts. . . . "Infrared satellite readings show that the Earth has been getting greener since 1982, thanks apparently to increased rainfall and CO2. Worldwide, vegetative activity generally increased by 6.17 percent between 1982 and 1999-despite extended cloudiness due to the 1991 eruption of Mount Pinatubo and other well-publicized environmental stresses. . . . "When dinosaurs walked the earth, there was from five to ten times more CO2 in the atmosphere than today. The resulting abundant plant life allowed the huge creatures to thrive. . . . Based on nearly 800 scientific observations around the world, a doubling of CO2 from present levels would improve plant productivity on average by 32 percent across species." The National Center for Policy Analysis echoes these sentiments and makes the bold claim that a desire for greater plant yield is why botanists pump CO2 into greenhouses. Even more astoundingly, this organization states that until just recently plants might have been suffering from CO2 deprivation. Get out and rev up those 4 X4s!
