President Obama had to leave the UN conference on global warming early because a major snowfall threatened to close airports on the US east coast. As it turned out he was not able to use his customary helicopter to fly from Andrews Air Field to the White House, but did the trip by car. Is there any wonder that there remains a healthy skepticism about the dangers of “global warming?” Of course the global warming warriors will no doubt attribute the major snow storm to rising temperatures. But then we now know that they are given to reworking the data to achieve the resutls they need.
