A new study published in Nature magazine shows that clouds and rainfall are migrating from the mid-latitudes towards the North and South Poles.
According to the World Resources Institute (WRI), a US sustainability think tank, this has big and worrying implications for food production. For centuries, these clouds have supported agriculture in these mid-latitude regions, which include the US Southwest, southern Europe and parts of the Middle East, southern Africa, Australia and Chile.
WRI's own models suggest diminished water supplies in these important food-growing areas will be apparent by 2020, and are expected to grow worse by 2030 and 2040.
