Climate Change and Food Security
Home​​
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
