Why does Earth have deserts?

Take a look at a physical map of the world. Thirty degrees on either side of the equator, you will see, distributed with suspicious regularity, a brown band of drylands circling the planet, a sere belt warding off greener climes: the deserts of the world. They are

GOCE revealed the height of sea is not the same everywhere on Earth

New precision gravity data from ESA’s GOCE satellite revealed that the sea is lower heading north along the east coast of North America. Winds, currents, tides and different temperatures cause seawater to pile up in some regions and dip in others, so in fact, the

Rising sea level will displace a substantial fraction of the human population

Globally, sea level is now rising at a rate of about a foot a century and the rate appears to be accelerating. Experts say the human emissions of greenhouse gases that may make a huge increase of sea level inevitable, are expected to occur in just the next few
