Two-Thirds of the Earth Is Covered by Clouds

Here’s an image of the Earth’s cloud cover, created by 12 years of satellite data.

Some of them look like big pillows or lines across the sky, while others may remind you of Winston Churchill’s profile. But at any given moment, about two-thirds of the Earth’s surface usually is covered by clouds, according to a NASA study based upon satellite observations.

For a long time, scientists have been trying to figure out exactly how that cloud cover might affect the climate change process — or how it might be altered by global warming.

It’s truly weird that you can see Hawaii, Galapagos, Canaries one other small island groups on this.

Why is that weird?
