Global warming really is NOTHING to worry about.

[subversive science]

There are a number of mechanisms by which weather will intensify as a consequence of climate change.

The relationship between global warming and hurricanes is still under investigation, as cyclo-genesis itself is still a topic of active research. Some of the effects of global warming, e.g., increased wind shear, may suppress the formation of cyclones, but there is some evidence that the storms that do form will be more powerful due to higher temperatures in both the atmosphere and the ocean.

In general, the increase in severe weather can be traced to a number of factors. Both modeling and empirical works show that increased warming will make wet areas wetter and dry areas dryer, leading to worse flooding and drought. As the surface warms, the Earth system will transfer that energy to the atmosphere through convection, intensifying storms.

Winter weather will also increase in a warming climate. Since there is more water in the atmosphere, there will be an increased chance of more and stronger snow storms. Changes in circulation can bring more cold air downward from the poles, also increasing the the possibility of winter weather.

Yes, but that's all guesswork isn't it? People can theorise as much as they like. It's not evidence.
Heat does not inevitably mean storms. On Jupiter, the temperature at the level that has the same pressure as Earth, 1 bar, the average temperature is about minus 100 degrees C.
But the storms and winds are very high, compared to those on Earth. Compare Jupiter to Venus, and it's the colder planet that has the storms. The incredibly hot planet isn't particularly stormy.

Storms generally need heat AND cold, to change that heat energy into kinetic energy of the air.
That's how you get the big thunderstorms in the US that cause tornadoes. Hot air from the south meets cold air from the north.
Global warming would produce more warm air, and less cold air. You need more of both, to predict more severe weather.

Yeah, the stuff from NASA is "just guess-work" but your stuff is water-tight, MM.

We're all guessing. That's the thing about climate science. It has no track record.
Well, it has a short and very poor track record of climate prediction.

My prediction track record is actually much better than the most expensive climate models. But that's just guessing from ignorance, just like them.

When you have numbers and stuff and put them in a graph and find a trend, I guess it's a guess. Did you want it to predict every hurricane 10 years ahead?

These effects are studied with models and corroborated with empirical evidence.
