Warming Will Reduce Wheat Production, Research Shows

The researchers found that wheat production would fall by 6 percent for every 1°C increase in temperatures. The world is now nearly certain to warm by up to 2°C compared with pre-industrial levels, with political efforts concentrated on holding the potential temperature rise to no higher than that limit. But some analyses suggest that if greenhouse gas emissions continue to grow at current rates then warming of as much as 5°C could be in store.

In forecasting the effect on wheat production – one of the world’s most important staple crops – the researchers tested 30 computer models against field experiments to establish the most likely scenario.
