As Clouds Head for the Poles, Time to Prepare for Food and Water Shocks 

A changing climate means less rain and lower water supplies in regions where many people live and much of the planet’s food is produced: the mid-latitudes of the Northern and Southern hemispheres, including the U.S. Southwest, southern Europe and parts of the Middle East, southern Africa, Australia and Chile. As WRI-Aqueduct’s future scenarios for water supply show, diminished water supplies will be apparent in these areas by 2020 – less than four years away -- and are expected to grow worse by 2030 and 2040. 

Now a new study in the journal Nature provides some of the first evidence that this widely-predicted phenomenon – the movement of clouds and rainfall from the mid-latitudes towards the North and South poles -- is already taking place. Just like the retreat of glaciers and polar sea ice, now clouds and rain are retreating poleward.

This will have huge implications for agricultural production, industrial and energy output, and municipal water provisioning. Many irrigated agricultural areas are already facing water stress. The climate-driven shift of clouds and rain – known asHadley Cell expansion – will put those areas under even greater stress in the future. Rain-fed agriculture, which many poor people depend upon, will also suffer as a result of reduced rainfall in the mid-latitude regions.
