The crisis is also spreading to warmer areas around the globe. In Australia, the conflict between humans and camels has risen.

Docker River is a small town in Australia's dry center. About a month ago, drought brought 6 thousand thirsty camels here to ransack every possible water source.

Jude Prichard, Resident from Central Land Council, said, "Two weeks ago there was no water in the community because camels worked out to push fire hydrants to get water, 42-degrees, no air-conditioning, you know the school had to shut down."

Australian authorities use helicopters to scare the camels away from the town into the open desert, where they would be killed by sharp shooters.

In facing the effects of climate change, scientists hope the Copenhagen conference can guide people to tackle these serious climate problems.
