RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:3000 rich people and GretaGreat debate. I agree that let the true scientist fight it out as the science is still not clear. For example, IMO a significant contributor to global warming has been increase desrtification. This has occurred over centuries as goat and sheep who are complete grazers (eat whole plant including the root) have been proven to be the major cause. Herders did not always do a good job in allowing plant restoration. Recent experience on a number of sites have been successfull in achieving significant recapture of desert by tightly restricting their range and introducing cows etc. The regreening of deserts and the global effort to plant one trillion trees will behave a major positive impact on climate.
