MESSING around with ecosystems is an unpredictable business. That proved true again this week when a group of Indian and German researchers gave their first report from the biggest ever experiment in geo-engineering: an expedition to pour iron into the Southern Ocean, a vast area that encircles Antarctica, to stimulate a giant bloom of phytoplankton.

Report calls for shift in climate research

The US government's climate research needs a radical refocus to make its results more relevant to policymakers and other stakeholders. That will require more interdisciplinary research and better understanding of the effects of climate change on local scales, says a new report.

Farmers face growing climate change dilemma: scientist
March 26, 2009 11:39 AM - David Fogarty, Reuters

The popular myth of 'water wars'
March 26, 2009 10:56 AM - , SciDevNet

Earlier this month the UN warned that climate change could spark conflicts over water. But the idea of future 'water wars' is a myth, says Wendy Barnaby. Neither Egypt, Israel nor Jordon produce enough water for their needs. But while they have fought wars with each other, it has not been over water, says Barnaby. Instead, areas in need of water import food as a 'virtual' boost to water supplies. Tony Allan, a scientist at Kings College London, says more water flows into the Middle East embedded in grain each year than down the Nile to Egyptian farmers.
