>The frequency, intensity and duration of all hurricanes, cyclones and tropical storms has been decreasing for the last several decades and recently hit a historical low.

This is not what I've gathered from the literature. Kerry Emmanuel published this paper:

>Increasing destructiveness of tropical cyclones over the past 30 years

Hmm. Sounds like the complete opposite of what you were saying. Maybe Emmanuel, despite being a dyed-in-the-wool conservative, is really just a communist agitator working for the Soviets. What are the other tropical storm experts saying?

>... models consistently indicate that greenhouse warming will cause the globally averaged intensity of tropical cyclones to shift towards stronger storms, with intensity increases of 2–11% by 2100. Existing modelling studies also consistently project decreases in the globally averaged frequency of tropical cyclones, by 6–34%... modelling studies typically project substantial increases in the frequency of the most intense cyclones, and increases of the order of 20% in the precipitation rate within 100 km of the storm centre.

Huh. That sounds like an <span class="math">increase[/spoiler] in intensity, not a decrease. Ok, well that's fine! Just a fluke!

>We examined the number of tropical cyclones and cyclone days as well as tropical cyclone intensity over the past 35 years, in an environment of increasing sea surface temperature. A large increase was seen in the number and proportion of hurricanes reaching categories 4 and 5.

Mm hmm.

>Svensson et al shows no change in flood magnitude or number in the last several decades.

Yeah, I bet he did. I like that you left out information like the publication year and journal name so that makes it harder to track down your citations. Very sneaky.

I can't believe you'd be willing gamble the safety of your own grandmother on bullshit analogies, so I hope you're a troll. If you aren't, well:
