NASA - First-of-its-Kind Map Depicts Global Forest Heights
Port Townsend School of WoodworkingI found these maps fascinating and kind of scary at the same time. Using a laser based remote sensing technology NASA has mapped the average height of forests around the globe. The darker the green the taller the trees. The linked article talks about where the carbon released by burning fossil fuels ends up and highlights the value of forestry as a carbon sink.
What I find scary is just how small a part of the globe still has big trees and, to me, emphasizes how important it is to conserve them and to create the next generation or big trees (tree generations are much longer than human generations).
