Hurricanes Are Moving More Slowly, Which Means More Damage (npr.org)
An anonymous reader shares a report: Hurricanes are moving more slowly over both land and water, and that's bad news for communities in their path. In the past 70 years, tropical cyclones around the world have slowed down 10 percent, and in some regions of the world, the change has been even more significant, according to a study published Wednesday in the journal Nature. That means storms are spending more time hanging out, battering buildings with wind and dropping more rain. "The slowdown over land is what's really going to effect people," says James Kossin, the author of the study and a tropical cyclone specialist at the National Oceanic and Atmospheric Administration. He points to Hurricane Harvey's effect on Houston as an example of what slower storms can mean for cities. "Hurricane Harvey last year was a real outlier in terms of the amount of rain it dropped," he explains. "And the amount of rain it dropped was due, almost entirely, to the fact that it moved so slowly."
More damage where they hit, but doesn't that also mean you have more time to evacuate people to get out of the path. In theory a slower moving hurricane may mean more damage but should it not mean less human fatalities? At least in places that have the financial ability to move people out the path.

After 70 years, I expect to be moving slower too.
Man slashdot can't stop carrying this garbage. If the hurricanes were fast moving the liberals would blame it there fantastical religion of global warming.
That's why it changed from "Global Warming" to "Climate Change". Any event meets the model and requires that we stop using any fuels
Turns out "liberals" are a large heterogeneous group of people.
Not every liberal believes the same thing.
Taken as a whole, something said by one liberal will probably contradict something said by another liberal.
Sometimes they call it "For every PhD, there is an equal and opposite Ph.D"
A state like Vermont is a good example. Overally politically liberal, and home of Senator Bernie Sanders, yet also, the NRA's Gold Standard ("Vermont Carry") for what ideal gun laws should look like.
Very slow storms can cause devastation by increased rainfall, as Harvey did, but because hurricane damage increases exponentially with wind speed: ...faster storms get increasingly dangerous more quickly with the extra wind speed that the leading quarter gets from hurricane speed added to ground speed than any "savings" from decreased time to pass by. The great New York hurricane of 1938 was only a Category 2 when it struck Long Island, but was moving unusually fast because of being squeezed between two adjacent weather systems that shot it forward like a watermelon seed. The summed wind velocity at the point of landfall made it as destructive as a Category 5.

We noticed already. But thanks for pointing that out.
Please do not read this sig. Thank you.
Eventually, it will reduce human population levels, possibly by 50%, and that's a good thing, right?

Isn't it funny how conservatives always try to paint liberals in such a negative light that they paint them all with such broad strokes applying the worst of the fringe to the group as a whole. All while ignoring that they are doing the same thing they are accusing the liberals of doing.
Dead people due to global warming is a good thing. It's the only possible cure.
No idea what you wanred to say, I basically stopped reading when you threw in the derogative about "liberals" ... what the fuck has political stance/orientation to do with this?
Cost free eBook I read (by iBook/Kobo/Amazon/ObookO/Gutenberg etc.): "The Green Odyssey" by Philip Jose Farmer.
there was no way to accurately track and measure hurricane velocity 70 years ago. through the 60s there were sporadically weather satellites each of which did not last very long. in the 70s and beyond, yes I'll believe claims of hurricane tracking/velocity
Even when they talk about stuff like black holes or the extinction of the human race they bring up the good it can do but Global warming is 100% evil.
In short, no, global warming does not do anything good. The situation that has permitted humanity to flourish on this planet is extremely precarious, and disrupting it is not positive.
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Its funny how liberals constantly say there is no objective good or bad and everything is shades of gray but global warming is like Satan.
It's funny how conservatives can only win straw man arguments.
You should go first Republican faggots. Walk your talk, bitches.
If a countries food production goes up because frozen tundra becomes more productive, that's bad?
Wake up to yourself.
Yes, it will melt the south pole so we can colonize it.
Datz cuz liberals gotz da brainz fillz width straw.
It is "affect people" not "effect people," unless you are in the movie business talking about people working in special effects.
Takes time for alt.right generated hurricanos to smash alt.left slut-skins. Progg-folks bury so deep in the mud even a virile male twister needs to just gouge and gouge before bones are uncovered.
If a countries food production goes up because frozen tundra becomes more productive, that's bad?
That's not how it works. No study has yet been produced which shows that total farm land will increase. Some have suggested that some lands which are not currently arable will become so, but more lands which are currently useful will become less so and the balance is negative.
Wake up to yourself.
The best part of waking up is drinkypoo in your cup!
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
Maybe we should not have erected millions of gian windmills all over the place to harvest "free" "renewable" energy by slowing down the natural air circulation of the planet.
Nothing's free. A windmill put into a smooth flow of air gets spun by slowing that air down and making it turbulent.
I'm asserting this mostly tounge-in-cheek... but just mostly. (there IS probably an issue there, but not likely enough to DIRECTLY slow hurricaines - though with that whole chaos theory butterfly wing flap argument...)
"In the past 70 years, tropical cyclones around the world have slowed down 10 percent"
"That means storms are spending more time hanging out, battering buildings with wind and dropping more rain."
So... If, in this simplified model, total damage = time spent under a storm, then why are they not mentioning the biggest factor? How many storms/year?
In middle school math terms:
If Bobby got 10 storms last year, and Sally got 9 storms this year that were 10% slower, how many watermelons do they have?
Translating to time spent under storms:
Bobby => 10.0, Sally => 9.9
Conclusion => slower storms * fewer storms = less total damage
Or even more compelling, after the relatively busy storm years around 07-09, the news media would simply not stop talking about how Florida would be completely destroyed within 3 years if this trend continued. There were idiots asking to redefine the scale to create a Cat6 storm that we'd be sure to see several times each year.
In the real world, however, there were relatively very few major storms over the last 10 years. In the above example, that would be like saying Bobby had a bad year with 3 storms, while Sally only got 1 storm that was 10% slower in 3 years.
Bobby => 3.0, Sally => 0.4
Same conclusion, but ooooh look! The biggest factor has nothing to do with the scare tactics they are spreading.
TLDR; This is yet another example of why I stopped paying attention to NPR years ago. They love to leave out key details to try and make your opinion for you, while still pretending to have the integrity the founders may have actually had.
Hurricane Hazel (1954) was a fast moving storm that produced a MASSIVE area of wind damage from NC to New York, followed by tremendous flooding in Toronto. This article is garbage.
I only do that with Progressives. Classical liberals are generally in their right mind and most of the time common ground can be had. With Progressives, it's their way or nothing. If you disagree with them, then your an imbecile that needs to have a bit of eugenics policy applied to your gene pool.
What's funny about that statement is that there's a Progressive faction out there that really wants a human kill off to save mother gaia.
I'm too lazy to RTFA. Can someone who did explain whether this...
"Hurricane Harvey last year was a real outlier in terms of the amount of rain it dropped," he explains. "And the amount of rain it dropped was due, almost entirely, to the fact that it moved so slowly."
...means total rainfall, or just rainfall per area in the affected zone (which I presume is smaller)? i.e. Is there a certain amount of rain that a cyclone or hurricane holds and it's being distributed over a smaller area, or does the slower movement somehow increase the total water volume?
