RE “ENVIRONMENTAL differences: US Senate candidates heating up on the state’s climate change issues’’ (Metro, Dec. 17): Is it really possible that Republican US Senate candidate Scott Brown doesn’t believe climate change is a problem? The Globe reports that when a constituent asked Brown if he thought global warming was a “big fraud,’’ Brown did not object. Rather, Brown responded that “the globe is always heating and cooling. It’s a natural way of ebb and flow.’’ Really? If this is the natural ebb and flow, why were almost 200 nations represented in Copenhagen?
We have long moved past a debate on the science of climate change. We can disagree about the remedy and cost, but not the science. As Energy Secretary Stephen Chu, a Nobel laureate in physics, famously remarked, everyone is entitled to their own opinion, no one is entitled to their own facts.
If Brown really doubts the science of global warming, then his position is radical, transcending conservative, partisan politics and descending to the level of Sarah Palin and those who can see Russia because, of course, the world is flat. We need greater vision and solutions.
