Climate change is already affecting food supplies
A leaked draft of an IPCC report due in 2014 shows how climate change is already affecting food security around the world.
The report, which a spokesperson for the IPCC described as a "work in progress", is likely to change before it is fully released in March 2014. However it lays out in concerning detail the conclusions of recent research on how climate change is affecting the world's food supplies today, and how it is likely to in the future.
The report concludes that climate is already having an effect on food security, and that while rising temperatures may have beneficial effects on agricultural production in limited areas, globally productivity is expected to be decrease two percent per decade for the rest of the century from what it would be without mankind's influence on the climate.
