Food production. Atmospheric carbon makes it easier for plants to grow. Cold climate is more difficult for humans to thrive than warm. The last mini-ice age was devastating for humans and we would be wise to avoid cooling the planet. What is the perfect temperature for earth? We don't actually know. The alarmist have been predicting run away inflation and by their calculations we have passed the point of no return. Either the alarmists are wrong, or we are all dead. In any case, we don't need the laws based on crony capitalism that will be pushed with the excuse of stopping global warming. The kyoto protocol was passed in other countries and it failed spectacularly. Waste of time. How do I know the alarmist are liars? There is technology available to reduce carbon... for example LFTR, and it is NOT being pursued because their goal is not saving the planet or resources, their goal is control.
