Well said, but your premise is wrong. Climate change, if it means a warmer planet, will have an overwhelmingly net positive impact on the planet, as evidenced by actual historical evidence. Which state's weather is more conducive to biodiversity and human life, Hawaii's or Alaska's? In last Sunday's Star-Advertiser, an article on page 14 noted that there are now 10 more frost-free days in the northern tier of the US. That translates into longer growing seasons, more abundant crops, and fewer deaths from cold weather (20 times more people die from exposure to cold than heat).
