Ny studie av orkanexperter visar att de atlantiska orkanerna har blivit mer intensiva och att de dessutom ökar i intensitet snabbare än förut. Studien omfattar inte de senaste årens rekordorkaner.
Scientists: Climate change makes Atlantic hurricanes stronger
The findings come in the wake of two of the most damaging years for hurricanes and other extreme events
A group of top hurricane experts, including several federal researchers at the National Oceanic and Atmospheric Administration, published striking new research Thursday, suggesting that hurricanes in the Atlantic Ocean have grown considerably worse and that climate change is part of the reason why.
The study focused on rapid intensification, in which hurricanes may grow from a weak tropical storm or Category 1 status to Category 4 or 5 in a brief period. They found that the trend has been seen repeatedly in the Atlantic in recent years. It happened before Hurricane Harvey struck Texas and before Hurricane Michael pummeled the Gulf Coast with little warning last fall. Hurricane Michael, for example, transformed from a Category 1 into a raging Category 4 in the span of 24 hours.

The increase in prevalence of rapidly intensifying storms, Kossin said, means both that there are more strong storms overall and that there are more risky situations near land.
“Rapid intensification is exceedingly dangerous because people, they’re not warned adequately, they’re not prepared, many of them don’t evacuate,” he said.
