Deserts

A small desert beetle is the inspiration behind a remarkable new sponge.

The world's deserts are under threat as never before, with global warming making lack of water an even bigger problem for the parched regions.

When densities grow, swarms of insects and herds of animals start to coordinate activities.

Droughts over the past five centuries have been as bad or worse as the most recent one. Bottom line: There simply is not enough water to go around.

The jet streams are on the move, and scientists say it could change rainfall long-term patterns around the globe.

This desert city is lush, creating a unique oasis for people and animals. In the new thinking, pollution is part of the ecosystem.
