Insurance compynies are really freaked out about climate change. (Yes, including those in the US, because its their money :D ) They calculate that at the end of the century they will have to pay a multiple because of natural desasters then today. Which they dont like, because they have to increase premium and that means that 1) less profit because the one who goes up first loses customers and 2) less profit because there will be people who cancel all those insurances.
This is absolutely true. I work in insurance.
Y'know the old Upton Sinclair quote "It is difficult to get a man to understand something, when his salary depends upon his not understanding it"? Well, there are more industries who depend on maintaining the illusion that climate change NOT happening (oil, automotive, plastics manufacturing, construction, real estate, etc. etc.) than industries that benefit if climate change is recognized and addressed (insurance, clean energy/technology).
Which is kinda weird, when you think about it, because there's not much else those two industries have in common, and frankly the general culture of insurance hasn't done well at addressing climate change, but we're doing better than most, precisely because we need to be able to predict the future in order to make money. We set the rates we charge for flood and wind insurance based on predictions from past events, but we recognize that the past events can't fully predict the future anymore.
TL;DR: Climate change is happening; you can tell because people who stand to lose money if we ignore it are saying so.
