Hurricanes become stronger and wetter

berkeley - Hurricanes become more powerful due to climate change. In addition, they provide more rain. This is shown by calculations by the American Berkeley Lab. The study is in the important science paper Nature.

The lab studied fifteen real hurricanes and typhoons, including Irma and Maria (2017), Katrina (2005) and Andrew (1992). Researchers had a supercomputer calculate what would have happened to the same hurricanes in other circumstances. For example, the computer took into account other temperatures of seawater and air, with a different humidity and with other levels of greenhouse gases.
