Food aid and other humanitarian efforts could be put together sooner and executed better, say UC Santa Barbara geographers Chris Funk, Greg Husak, and Joel Michaelsen. After over a decade of gathering and analyzing climate and vegetation data from East Africa, the researchers, who are part of the U.S. Agency for International Development’s Famine Early Warning System Network (FEWS NET), say there is enough evidence to associate climate conditions in the region with projected rainfall deficits that could lead to food shortages.
We knew there must have been a connection between climate warming and damaging droughts in the world’s largest rainforest, as the two globally hottest years on record (2005 and 2010) coincide with the two record droughts in the Amazon – … Continue reading →
