And if you (and the other climate denialists peddling this idiotic view) actually believed that, then there's a clear route to you becoming very rich. Currently the major reinsurance companies are all pricing in climate change as part of their risk profiles. If climate change isn't real, then the actual risk is much lower than the reinsurers are accounting for. So, why not set up your own reinsurer, undercut the rest of the market, and make billions?
No, seriously. Why are all the right-wing billionaires behind the "climate change is a hoax" think tank not actually fronting up their own cash? Are they so stupid as to leave free money on the table?
