A new academic paper suggests introducing a higher number to categorize ocean-born storms, as global warming makes them gustier. Yet often times it’s not wind that kills.
Category 5 has become part of the world’s lexicon to describe a disaster of monumental proportion.
Now, thanks to climate change, a pair of scientists don’t think that is a dire enough level to describe hurricanes. They raise the possibility, on a “hypothetical” basis, for a Category 6.
Global warming has increased the energy available for storms to grow stronger, according to a paper by Michael Wehner, senior scientist at the Lawrence Berkeley National Lab, and James Kossin, climate and atmospheric professor at the University of Wisconsin. Their work was published in Proceedings of the National Academy of Sciences of the US.
The scientists make a case for adjusting the five-step, Saffir-Simpson Hurricane Wind Scale, which is used to describe hurricane power. A Category 5 is assigned when storm winds reach 157 miles per hour, and today that goes up to the limit of physics. Wehner and Kossin suggest considering anything over 192 mph a Category 6.
