The problem is scientists don’t know exactly how much. At the moment, forest cover is mapped from space using satellites that can tell the difference between surfaces such as forest, grasslands and desert, for example. But they don’t show whether a tree in a forest is ten metres tall or 100 metres tall, and that is a critical piece of climate information. ÍèÒ¹µèÍä´é·Õè âçàÃÕ¹ºéÒ¹·Ñº·é͹¹Ò¹ÒÊÒÃÐ ¼ÙéÊÙ§ÍÒÂØ | |
