Climate change will reduce crop yields sooner than we thought
16 March 2014 (PhysOrg)
– A study led by the University of Leeds has shown that global warming of only 2°C will be detrimental to crops in temperate and tropical regions, with reduced yields from the 2030s onwards.
Professor Andy Challinor, from the School of Earth and Environment at the University of Leeds and lead author of the study, said: "Our research shows that crop yields will be negatively affected by climate change much earlier than expected."
"Furthermore, the impact of climate change on crops will vary both from year-to-year and from place-to-place – with the variability becoming greater as the weather becomes increasingly erratic."
The study, published today by the journal Nature Climate Change, feeds directly into the Working Group II report of the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report, which is due to be published at the end of March 2014. (Read More)
