There’s a rule of thumb that rainfall intensity increases by about 7% per degree Celsius as temperatures rise. But the increase is much higher in the mountains, scientists found.
As the atmosphere warms, it can hold more moisture. This brings more intense downpours but also accelerates warming – because water vapour is a powerful greenhouse gas.
The Earth should be safe (and habitable) for a few billions of years, but we still need to worry about the impact now of just a few degrees of global warming.
Climate change has boosted the likelihood of heavy rainfall, hailstorms, flooding and drought seen in some parts of the world. What does the future hold?
If we had not altered the composition of the atmosphere at all through emitting greenhouse gases, particulate matter and ozone-destroying chemicals, the average temperature would have remained stable.
