Not mysterious. This is perfectly in line with expected science.

Climate is a huge chaotic system, akin to how Jupiter's Great Red Spot persists as a chaotic phenomenon. It's impossible to predict in detail, but follows some general principles we can depend on, and the generalization 'wind speeds are increasing' is one of those principles.

As we increase the energy of the overall system (by heating it), the range of weather behavior grows more extreme and more chaotic. Pretty sure this has at least as good a claim on observed wind speeds increasing, as any ocean pattern.

So the range of behavior will expand (higher peak speeds) and the rapidity with which the weather can change will also expand (is expanding). That poses dangers but if you can capture and store the energy it also gives opportunities: the danger is simply that expanded storms will smash our civilization, but the opportunity is that sufficiently sturdy generating equipment can harvest a LOT of power in a big hurry. Our ability to expend energy (even in so catastrophic a way as thermonuclear war) is NOTHING to the power of heating climate. We only think it is a certain way because we're used to seeing it that way.

There effectively is no such thing as the 'thousand year' storm anymore. It becomes commonplace, and design has to take on challenges like the million or billion year storm… as calculated under last century's conditions. Because that's how chaos works: small increases in total energy can give rise to increasingly spectacular chaotic flows.

One thing about it, it's fairly likely that any particular extreme will blow over more quickly. It all becomes a challenge of 'survive what climate threw at you during this 48 or 72 hours' and it'll likely change very aggressively again, perhaps to something a lot more survivable. You prepare for weather events like they are 'shock and awe' military assaults, no matter where you are in the world, because that's how it increasingly is. Wind speed is only one part of it, but it's certainly a significant part for unprotected humans and human structures.

Although there may be more total energy in the atmosphere, the polar regions are warming faster than the tropics. This would seem to decrease the temperature gradient as a function of latitude and slow convection. It must be that average wind speeds are mainly determined by the vertical temperature gradient as a function of altitude?

Wild guess: Maybe large-scale wind speeds will decrease, but short-term wind speeds, associated with storm systems, will increase.

That might not be such a good thing for wind power.

As I understand it, atmospheric water content is a huge factor. Greenhouse forcing from CO2/CH4 increases water content. And increased water content leads to increased greenhouse forcing.

Plus lots more heat energy available when some of that water condenses. Sort of like a steam engine.
