2ºC Warming Can Seriously Threaten Crops, Food Security More Than Thought

2ºC Warming Is Enough To Seriously Threaten Crops, Food Security More Than Thought says a new study, reports Ari Phillips in Climate Progress. Published in Nature Climate Change, it found that assuming a 2 C (4 F) degree rise by 2050, all crops worldwide will be experiencing great declines sooner due to extreme heat waves, and that basic cereal crops such as wheat and corn could experience dramatic declines, especially beyond 2050. Soybeans and spring wheat could show yield increases, however, although likely decline in tropical and subtropical areas. Previous research indicates that while some plants grow better under higher CO2 levels, this does not increase the overall nutritional resource (such as protein) in the plants / , so still threatening food security. Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: . This is an ongoing campaign (the next Congressional election is this year!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
