Rising atmospheric carbon dioxide levels are bolstering plant life throughout the world, environmental scientists report in a newly published peer-reviewed study. The findings, published in Geophysical Research Letters, are gleaned from satellite measurements of global plant life, and contradict assertions by activists that global warming is causing deserts to expand, along with devastating droughts.
A team of scientists led by environmental physicist Randall Donohue, a research scientist at the Commonwealth Scientific and Industrial Research Organization in Australia, analyzed satellite data from 1982 through 2010. The scientists documented a carbon dioxide “fertilization effect” that has caused a gradual greening of the Earth, and particularly the Earth’s arid regions, since 1982. The satellite data showed rising carbon dioxide levels caused a remarkable 11 percent increase in foliage in arid regions since 1982, versus what would be the case if atmospheric carbon dioxide levels had remained at 1982 levels .... http://www.climatechangedispatch.com
