Oh, Tulsi, get a grip.  The agreement is non-binding.  There are no teeth in it, no way to make China quit blowing foul stuff out of its smokestacks, no way to ensure any of the countries follow-through.  It's all about Global Redistribution of Wealth from the developed world, including the U.S., to the not-so-wealthy world.  It's all a big show signifying nothing.  Nothing will change for Hawaii except our social problems, which are unrelated to climate change/global warming/redistribution of wealth, will get worse and worse.  Our long rule by Tulsi's party teaches us that.
