Australia will need years of above-average rainfall to end drought
Australia will need several years of above-average rainfall to end a drought that has devastated crops in three of the last six years, according to the Bureau of Meteorology. According the the Bureau, the combination of heat and drought during the past five to 10 years is "without historical precedent and is, at least partly, a result of climate change." This year, wheat growers in the West have received enough rain to plant the next crop, but farmers in the East are still waiting. According to Lisa Ainsworth of the USDA, these global challenges to farming, including temperature and drought, won't be going away any time soon. Demand for grains is on the rise globally, and rising temperatures can cut yields, especially in tropical zones. Ozone pollution is another threat, as ozone can cut plant productivity, and is a growing problem in the Northern Hemisphere.

Maybe now they have come to their senses (by signing the Kyoto Protocol), maybe they can put pressure on their buddies in the White House to do the same.
