Cyclones slowing and intensifying - new research

The research, published today in the journal Nature, measured cyclones from 1949 to 2016 and found that the speed at which they move has slowed by 10 percent.

The slower a cyclone moves over the ocean, the more moisture and intensity it gathers; the slower it moves over the land, the more time it spends drenching it.

James Kossin's research showed that over the past 68 years, cyclones have slowed by 10 percent globally as the planet warms.

In this region, it's been even more dramatic.
