Taking out an insurance policy
The government impact in beginning to cope with climate change is quite low: additional investment in R&D, which, to quote from the article, is “a rounding error”, income (that could be selectively ploughed into compensation, research, temporary subsidies) from carbon taxes and different policies. The impact on the players in the private sector would be huge. The oil sector would be negatively impacted, for one.
