Ny studie bekräftar vad som tidigare har sagts: Uppvärmningen leder till att blöta områden blir blötare och torra områden blir torrare. Det blir alltså svårare att säkra tillgången på vatten i vissa områden.
Och ju högre temperaturen blir desto större blir problemet.
Climate change will cause more extreme wet and dry seasons, researchers find
The world can expect more rainfall as the climate changes, but it can also expect more water to evaporate, complicating efforts to manage reservoirs and irrigate crops in a growing world, according to a Clemson University researcher whose latest work has been published in the journal Nature Communications.

The best case scenario for relatively stable water availability during wet and dry seasons is that the global temperature will stabilize at 2 degrees Celsius over pre-industrial levels, according to the study.
But researchers also looked at what would happen if the temperature were to rise to 3.5 degrees Celsius or 5 degrees Celsius over pre-industrial levels by the end of the century.
The higher the temperature, the more variation in water availability, researchers found.
