[Vision2020] Mutually Insured Destruction

[Ted Moffett]

Insurance companies don't have a political or ideological agenda, for the
most part.  They look at the facts and do the math to objectively calculate
risk probability of events they insure for... Thus if insurance industry
think tanks, as referenced in this article, are already calculating the
costs of climate change, the "global warming is a hoax" or "global warming
won't be destructive" arguments are on rather weak factual and rational
grounds, it would appear...

To quote from this article:

"Denying climate change isn't just foolish---it's bad for business"
--------------------------------------------

"Florida is a case in point. There, where some 2.4 million people live less
than four feet above the high-tide line and where many U.S.-bound
hurricanes are likely to pass, insurers can only use historical models to
calculate risk. Climate scientists estimate that sea levels will rise
anywhere between 8 inches and 6.6 feet by 2100 — enough to inundate whole
neighborhoods in Miami, even on the lower end. The past offers a
comfortable fiction that could limit rate hikes by writing the risk off the
books.

As more groups like the Geneva Association call for risk models that
account for climate change, politicians are going to get a different
message. Denying climate change isn’t just foolish — it’s bad for business."
