The Global Warming Debate
RAINFALL patterns over east Africa have changed in a way that makes severe droughts more likely - and this means aid agencies need to rethink the way they operate.

Delay Of Bloom Blamed On Climate Change
Oddball spring flowers that seem unaffected by climate change — or have gotten it backwards — could be taking some cues from unusual autumns the year before. Like their early flowering peers, plants in a new study show that many of these on-time and late bloomers also have had their timing shifted by a warming globe — but the paradoxical effects have just been more difficult to observe.
Throughout the world, climate change is causing age-old ecological partners to miss their cues as seasons shift.

By Zoe Corbyn A common assumption is that rising global temperatures will increase the spread of malaria -- the deadly mosquito-borne disease that affects millions of people worldwide. But a study out today in Biology Letters finds that warmer temperatures seem to slow transmission of malaria-causing parasites, by reducing their infectiousness.

Mowing down seagrass meadows will cut loose carbon - environment - 20 May 2012
They may be trickier than trees for environmental protesters to chain themselves to, but it turns out that seagrass ecosystems hold as much carbon per hectare as the world's forests – and are now among its most threatened ecosystems. In the past century, 29 per cent of seagrass has been destroyed globally ", mostly by water pollution, dredging for new developments, and climate change. With seagrass meadows disappearing at an annual rate of about 1.5 per cent, 299 million tonnes of carbon are also released back into the environment each year, according to research published this week in Nature Geoscience (DOI: 10.1038/ngeo1477).In the struggle against global warming, the Amazon rain forest may be about to switch sides. Its dense vegetation has long helped cool the planet by removing carbon dioxide from the atmosphere.
Amazon May Become Greenhouse Gas Emitter - Science News
Fewer jobs, dwindling savings, piles of public debt -- there's not much reason to be thankful for the global recession. But one small silver lining is that it has slowed the rate at which we're turning the atmosphere into an over-amped electric blanket.
Forest Bump - By Charles Kenny | Foreign Policy
While average global temperature will still fluctuate from year to year, scientists focus on the decadal trend. Nine of the 10 warmest years since 1880 have occurred since the year 2000, as the Earth has experienced sustained higher temperatures than in any decade during the 20th century. As greenhouse gas emissions and atmospheric carbon dioxide levels continue to rise, scientists expect the long-term temperature increase to continue as well.
