A view from NASA

NASA's got some pretty cool and informative images in their locker (having loads of satellites and technology helps). Their prespective on climate change is one from above. Like the things that can be seen from space, such as aquatic dead zones and forest canopy heights.

Aside from knowing where the tallest trees are in the world, NASA explains,

'Scientific interest in the new map goes far beyond curiosities about tree height. The map has implications for an ongoing effort to estimate the amount of carbon tied up in Earth’s forests and for explaining what sops up 2 billion tons of “missing” carbon each year'.

Another interesting NASA image is of aquatic dead zones. Without pointing out the obvious, one can see the dead zones happen to exist where the highest density of people live.

While all can maps have distortions, NASA's use of satelitte imaging and laser technology produce widely accepted and very real data- most of which is collected over several years.

NASA's Eye's on the Earth contains images of change which demonstrate how areas have evolved over time.

The same way you'd compare baby photos of a person to their present self, images of change show an ever changing and evolving planet.
