Global food crisis will worsen as heatwaves damage crops, research finds.
Harvests will fall dramatically during severe heatwaves, predicted to become many times more likely in coming decades
(two studies Jan 2013)

Global warming induced heat
waves, drought, and
flooding constitute a global food security emergency for us all today, to protect our near and long term future food security- the world's top food producing regions of the temperate Northern hemisphere are now global warming & climate
change vulnerable.

Changes in climate are already
affecting the sustainability of agricultural systems and disrupting
production
Unless the emissions of GHGs are curbed .. changes in temperature, precipitation, and other climate variables will undoubtedly affect agriculture around the world

Climate change: how a
warming world is a threat to our food supplies
Global warming is exacerbating political instability as tensions brought on by food insecurity rise. With research suggesting the issue can only get worse we examine the risks around the world. The Observer 13 April 2013

9. "Agriculture Rising temperatures, extreme heat, drought, wildfire on rangelands, and heavy downpours are expected to increasingly disrupt agricultural productivity in the United States. Expected increases in challenges to livestock health, declines in crop yields and quality, and changes in extreme events in the U S and abroad threaten rural livelihoods, sustainable food security, and price stability."
