During the Democratic  debate last night, both candidates said we need laws to prevent climate change.  They seem to think that the government can write laws that will alter keep the climate. the same as today.   They assume that carbon (in reality, carbon dioxide) is altering the temperature of the planet.  They propose laws to restrict carbon from being burned in power plants.  However none of the current climate models are accurate enough to predict how much the earth cooled as a result of the laws.  It will just be a guess.

When I was studying ozone concentrations in  Connecticut, I proposed a law that the government eliminate all temperatures above 90 degrees in Connecticut.   Then all the high ozone days would be eliminated in the state.  At least, if this could have been enforced, the results would be obvious.
