    Although overall global rainfall is expected to increase, climate change is likely to have negative impacts on water resources in many regions, through a combination of shifting rainfall patterns, melting glaciers and more evaporation. A warmer world will also lead to an intensified water cycle, with heavier bursts of rain punctuated by longer dry spells. These effects could increase water stress for many people around the world.
