DROUGHT DROUGHT

Climate scientists suspect that Global Warming prompted disruption of atmospheric circulation patterns could have devastating effects:

As the descending of dry air, or "downwelling", from the upper atmosphere moves toward the poles, the droughts already experienced in the Mediterranean and south-western Australia could get worse.

The changes observed so far match those predicted by computer models for greenhouse warming of 0.5°C, Reichler told New Scientist. He suspects global warming is behind the changes, but cautions that the mechanisms pushing the expansion of the tropics are not yet understood.

Might want to check those models; there is no drought in south-western Australia.
