For more than 50 years, the National Hurricane Center has used the Saffir-Simpson Windscale to communicate the risk of property damage; it labels a hurricane on a scale from Category 1 (wind speeds between 74 - 95 mph) to Category 5 (wind speeds of 158 mph or greater). But as increasing ocean temperatures contribute to ever more intense and destructive hurricanes, climate scientists Michael Wehner of Lawrence Berkeley National Laboratory (Berkeley Lab) and James Kossin of the First Street Foundation wondered whether the open-ended Category 5 is sufficient to communicate the risk of hurricane damage in a warming climate. So they investigated and detailed their extensive research in a new article published in the Proceedings of the National Academy of Sciences (PNAS), where they also introduce a hypothetical Category 6 to the Saffir-Simpson Wind Scale, which would encompass storms with wind speeds greater than 192 mph. ... According to Wehner, anthropogenic global warming has significantly increased surface ocean and tropospheric air temperatures in regions where hurricanes, tropical cyclones, and typhoons form and propagate, providing additional heat energy for storm intensification. When the team performed a historical data analysis of hurricanes from 1980 to 2021, they found five storms that would have been classified as Category 6, and all of them occurred in the last nine years of record. They determined a hypothetical upper bound for Category 5 hurricanes by looking at the expanding range of wind speeds between the lower-category storms. https://www.preventionweb.n...hurricanes
In summary, they looked at hurricanes from 1980 to 2021 and found that, since 2012, we had 5 hurricanes with winds greater than 192mph. These levels had never shown up since we started logging them until 2012.
And right now it looks like Milton will reach that level, too.

I just saw the video from a cell phone from the storm that hit 500 years ago, it was in black and white.

You go ahead and talk to yourself, fart boy... I've got work to do.

Have you disparaged any more hurricane victims, honey?

DB is excited. He can make fun of more hurricane victims.
I notice DB isn't too keen on giving weather reports anymore.

The Great Florida Migration Is Coming Undone
A surplus of housing inventory and dwindling buyer interest are slowing sales. Hurricanes and extreme weather are making it worse.

Some Floridians will be wiped out twice this hurricane season. Some have second homes in western NC that Helene wrecked and now a big storm is bearing down on Tampa.
But hurricanes are not new... what do you think it was that sank all those Spanish treasure ships 300 years ago?

There are three Global Warming Storms in the Hotlantic right now. There is room for three more. Florida will be destroyed this week. If only Al Gore had won in 2000.
