Global tree canopy cover increased by 2.24 million square kilometers (865,000 square miles)
between 1982 and 2016, reports a new studyin Nature.
Researchers using satellite data tracked the changes in various land covers to find that gains in forest area in the temperate, subtropical, and boreal climatic zones are offsetting declines in the tropics. In addition, forest area is expanding even as areas of bare ground and short vegetation are shrinking. Furthermore, forests in montane regions are expanding as climate warming enables trees to grow higher up on mountains.
