Several sources make varying claims that 70% of the global economy is sensitive/dependant on the weather:

Is there evidence to support this claim?

    What is that supposed to mean exactly? If you are talking about an area that gets weather such as a blizzard or hurricane that would impact everything and isn’t really a good measure.

    @JoeW: The definitions are unclear and contradictory between sources, but there seems to be a common meme between them and others. Maybe we can find the source and clarify.

    What would the remaining 30% be? The only human activity not affected by the weather are autonomous systems already in space, which are very very few. I would take any claim it's less than 100% with a big grain of salt unless "weather sensitive" is more accurately defined. With bad enough weather, all human activity ceases.

    @Oddthinking The oldest reference in the second paper that claims 70% is Hanley, H., 1999. Hedging the Force of Nature. Risk Professional, pp. 21–25. Since they all claim 70%, I suspect that that paper is the source. Jan 11, 2023 at 14:11

    @DavidHammen I haven't found the paper by Hanley, but another reference to it says "It is estimated that nearly 30% of the US economy and 70% of the US companies are affected by weather" which isn't quite what the Q title says. Jan 11, 2023 at 15:18
