Good attempt at argument by analogy but it breaks down over one point, which is quite instructive.  The fire marshal has the benefit of past experience.  "Of the last 50 times I flagged this hazard, 49 of their businesses burned down."  In the case of climate whatever, we have no such past experience. In the 1960s, global temps were dropping dramatically.  The message was: "Ice age is coming.  It is unstoppable and it's big oil's fault."  Then when the cycle turned, the message became, "Global warming.  The seas will rise.  The poles will melt and it's big oil's fault."  Then global temps flattened and it was 'climate change', "Oh boy, look for more extreme weather and it's big oil's fault."  We just don't know enough about what we don't know to even begin to say in any sort of engineering or management sense, "what is a reasonable response?"
