Inconvenient Study: CO2 fertilization greening the earth
International team reports CO2 fertilization prompted plants and trees to sprout extra green leaves equivalent in area to two times the continental USA.
Canadian farmers are thankful for the longer growing season and the greater abundance of atmospheric carbon dioxide that better feeds plants. So should the rest of us.After all, Earth is nearing the end of its current interglacial period and the resurrection of mile-thick glaciers in coming millennia, according to the pattern of geological history.
CO2 has a proven track record of helping our closest relatives thrive. If all the failed doomsday predictions wasn’t proof enough that we have nothing to fear from more CO2, the final proof that CO2 is good for us is that our monkey ancestors thrived in a much hotter world. The Palaeocene-Eocene Thermal Maximum, 5-8C hotter than today, was the age of monkeys. Our monkey ancestors feasted on the abundance of the hothouse PETM, and colonised much of the world, only retreating when the cold returned.
So I hope you will all join me in raising a glass of your favourite beverage to celebrate this milestone in human well being and industrial progress, and drink to humanity achieving a milestone I hope to be alive to see – 500ppm of CO2 by the middle of this century.
And:
Predicted surges in sea level have failed to manifest. This prediction dates back to 1989 – you would think after 35 years of getting it wrong, scientists would stop banging on about the same failed theories.
