About four billion tons end up in the atmosphere and two billion tons dissolve in the ocean. Heres what the science says. The remaining 195 countries and regions below 1%, combined, account for the other half of Earth's land surface. In a study, published in the journalNature, Thomas Crowther and colleagues (2015) mapped tree density across the world.3To do this, they utilised 429,775 ground-sourced measurements of tree density from every continent on Earth to generate a global map of forest trees. 16 million square kilometers show continued land degradation (the size of South America) A persistent, long-term decline in vegetative productivity is observed for 12-14% of agricultural, pasture and grazing land, and natural areas - with sub-Saharan Africa worst affected.

Some of the world's semi-arid regions are turning into desert at an alarming rate. Global deserts occupy approximately one quarter of the Earth's land surface [Ezcurra, 2006].This ratio of deserts to global land area has been projected to increase with global warming [Huang et al., 2015].Desertification in the semiarid regions in the past several decades has contributed a negative forcing by reflecting more solar radiation, equivalent to ~20% of the global . But what percentage of the Earths land surface is desert? The downsizing of the Grand Staircase-Escalante National Monument poses a threat to some of the 660 bee species that live in the area, while the prospect of a border wall between the U.S. and Mexico could disconnect a third of 346 native wildlife species from 50 percent or more of their range that lies south of the border, including the desert bighorn sheep.
