Climate Change and Food Security
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

19 Dec 2014 Climate change cut to world food output 18% by 2050 ​​
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

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
