Researchers show in Science Advances that the probability of extremely warm and extremely dry conditions has doubled worldwide.
They warn for the threat this poses to worldwide agricultural production. Before anthropogenic climate change chances of extreme weather in multiple agricultural key regions were slim. At the same time the global marketplace could compensate for a bad harvest in one region. The researchers see erosion of this buffer. They specifically point out that the frequency of these simultaneous extreme hot and dry conditions will increase with 20% in the next three decades.
