Oh, sweet Thomas, you don't understand what science is. Here is Chris Landsea, the foremost expert on hurricanes in the world.
Chris Landsea wrote:There’s no statistical change over a 130-year period. Since 1970, the number of hurricanes globally is flat. I haven’t seen anything that suggests that the hurricane intensity is going to change dramatically. It looks like a pretty tiny change to how strong hurricanes will be. It’s not zero, but it’s in the noise level. It’s very small.
https://www.nbcdfw.com/news/national-in ... 64611.htmlYou probably don't recognize the name, but Landsea famously quit the IPCC over this very thing.
Citing a politicized agenda and misrepresentations of climate science, prominent climate scientist Chris Landsea on January 17 resigned his post as a participant in the Intergovernmental Panel on Climate Change (IPCC)
....
Landsea is one of the world's leading hurricane researchers, specializing in seasonal and climatic relationships of Atlantic tropical cyclones. He served as chair of the American Meteorological Society's (AMS) Committee on Tropical Meteorology and Tropical Cyclones for the years 2000-2002. He was recipient of a National Oceanic and Atmospheric Administration (NOAA) Post-Doctoral Fellowship in Climate and Global Change for the period 1995-1996.
In his resignation letter, Landsea documented how the IPCC had sanctioned a "misrepresentation" of hurricane research and issued "unfounded pronouncements" to the media that "subverted and compromised" the scientific assessment of the IPCC's hurricane researchers. According to Landsea, statements made by the IPCC to the media demonstrated "preconceived agendas" that are "scientifically unsound."
https://www.heartland.org/news-opinion/ ... =policybotThis paper that you cite, from Nature, is, at best, conjecture. It's a theory, which has not in any way been substantiated through empirical observation. Thomas, you do not understand how this academia stuff works. Getting a paper in a journal isn't hard. These journals are not scripture. They carry no "authoritay" whatsoever. Over time a certain publication may be considered as relevant by the community, but this particular paper you cite certainly has not reached that point. We can review in say 20 years and see how it's doing.
Hurricane Harvey is cited as a potential example, however there are reasons for it stalling over Houston that have nothing to do with supposed man-made climate change. Plus, why are you bringing this up? Kossin supports the point I was making earlier re hurricanes, that an increase in average temperatures, or a decrease in differential temperatures, would result in a slowdown and decrease in frequency.
It is such a funny thing. You have hurricanes, which are a random weather anomaly, and which can be affected by thousands of variables, but people think they can boil it down to just one. And they can't even decide whether they are good or bad. Increase in frequency = bad. No, wait, decrease in frequency is bad. Because that means they will stall out and drop more rain. Or something. Flooding in one area is worse than the hurricane having a larger geographic damage path. Seriously can't make this stuff up.
So how did this theory work out for hurricane Michael which just happened? Answer, it didn't. The hurricane did not stall, it proceeded quickly inland clipping Georgia and Alabama. But hey, it's only one hurricane. Just like Harvey, the one hurricane doesn't make or break a theory. Let's see how it looks after a few hundred hurricanes.
