Many damaging effects of climate change are already basically irreversible, researchers declared Monday, warning that even if carbon emissions can somehow be halted, temperatures around the globe will remain high until at least the year 3000.

She defines "irreversible" as change that would remain for 1,000 years even if humans stopped adding carbon to the atmosphere immediately.

Global warming has been slowed by the ocean, Solomon said, because water absorbs a lot of energy to warm up. But that good effect will not only wane over time, the ocean will also help keep the planet warmer by giving off its accumulated heat to the air.

Solomon's paper concludes that if CO2 is allowed to peak at 450-600 parts per million, the results would include persistent decreases in dry-season rainfall that are comparable to the 1930s North American Dust Bowl in zones including southern Europe, northern Africa, southwestern North America, southern Africa and western Australia.
