Hurricane Ida strengthened overnight and developed into a Category 4 storm within hours

While researchers cannot say for certain whether anthropogenic climate change would produce longer or more active hurricane seasons in the future, there is widespread agreement on a point: global warming is changing storms.

“Potential intensity is going up,”Kerry Emanuel

“The maximum energy potential is starting to increase,” said Kerry Emanuel, a professor of atmospheric sciences at the Massachusetts Institute of Technology.

In a 2017 paper, which relied on climate and hurricane models, Emanuel found that storms that accelerate rapidly and raise wind speed by 70 km / h or more are rare in the period from 1976 to 2005.

Indeed, each degree of warming of the air allows for approximately 7% more water to absorb.

He estimated that storms that quickly strengthen in the 24 hours before landing as well as increase their wind speed by 70 km / h or more generally occur once per century on average during these times.

Kossin likened the problem to strolling through the backyard, used a hose with water on the floor.

This could mean those storms that come ashore at higher latitudes such as the US or Japan.

Climate change

Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. (wikipedia)
