Heat may spark world food crisis

Definitely a no-brainer…
“Half the world’s population could face climate-induced food crisis by 2100, a new report by US scientists warns. Rapid warming is likely to reduce crop yields in the tropics and subtropics, according to Prof David Battisti of the University of Washington. The most extreme summers of the last century will become the norm, he calculates, using 23 climate models. We must urgently create crops tolerant to heat and drought if we are to adapt in time, he writes in Science journal. The study is based on combined direct observations with projections from 23 global climate models that contributed to the Intergovernmental Panel on Climate Change’s (IPCC) 2007 global assessment. They calculate there is greater than 90% probability that by 2100, the average growing-season temperatures in the tropics and subtropics will be higher than any temperatures recorded there to date.” – Source
