1/8. The IPCC authors expect  a worsening trend. No such trend is actually detectable, so far. In fact, here's a paper about the downward  trend in hurricane destructiveness, tho I suspect the decrease might be a fluctuation rather than a durable trend. nature.com/articles/ncomm

2/8. The IPCC authors are sly. They know hurricanes & other tropical cyclones aren't worse, but they dodge & weave to avoid admitting it. Here's a tricky quote from AR6: "It is likely that the global proportion of Category 3–5 tropical cyclone instances has increased over the past four decades." ref: ipcc.ch/report/ar6/wg1
3/8. That's a textbook illustration of Chesterton's point: "Falsehood is never so false as when it is very nearly true." It's "spin." It is calculated deception without QUITE lying. Look at that graph again: (Updated version: climatlas.com/tropical/globa )
4/8. Do you see it? The frequency of MAJOR hurricanes is only down slightly, but the frequency of ALL hurricanes is down significantly. That means "the global PROPORTION of Category 3–5 tropical cyclone instances has increased."
5/8. It sounds like bad news, but it's actually just a dishonest spin of what is actually good news. (So, do you wonder why so many smart people distrust the IPCC?) sealevel.info/resources.html
6/8. Nor have other kinds of storms worsened. Even the IPCC admits that, though they "project" worsening. They say: "There is low confidence in past changes of maximum wind speeds and other measures of dynamical intensity of extratropical cyclones. Future wind speed changes are expected to be small, although poleward shifts in the storm tracks could lead to substantial changes in extreme wind speeds in some regions (medium confidence). There is low confidence in past trends in characteristics of severe convective storms, such as hail and severe winds, beyond an increase in precipitation rates. The frequency of spring severe convective storms is projected to increase in the USA, leading to a lengthening of the severe convective storm season (medium confidence); evidence in other regions is limited."
7/8. In fact, though the IPCC does not admit it, there's a very  clear downward  trend in severe tornadoes. sealevel.info/learnmore.html

Thanks. I remembered that "Energy for Future Presidents" by Muller said there was no worsening trend, so I checked IPCC, and it says there is. It's surprising that there is disagreement on the long-term trend.
8/8. To understand #ClimateChange (or any other politicized topic), you need balanced information. I'm here to help. sealevel.info/learnmore.html This resource list has: • accurate introductory climatology information • in-depth science from BOTH skeptics & alarmists • links to balanced debates between experts on BOTH sides • accurate information about climate impacts • links to the best blogs on BOTH sides
