An important scientific report announced “irrefutable（不能反驳的） proof” that climate change is

An important scientific report announced “irrefutable（不能反驳的） proof” that climate change is happening and it’s all our fault. How long has it been before people are against the global warming idea? But here’s a funny thing. Last year there was a very bad hurricane season in the Caribbean when, among other disasters, New Orleans was all but wiped off the map. We were wisely informed by the experts at the time that this was owing to global warming.
I remember watching a BBC science programme and hearing a learned professor with a beard tell us, “The increased frequency and strength of hurricanes is what we shall have to learn to expect given global warming.”
This year there have been far fewer hurricanes and those there have been were relatively mild. Why？Global warming again of course. Professor Bjorn Lomborg, author of The Skeptical Environmentalist, writes, “In the constant media reports of possible greenhouse related disasters, almost any event is now linked to climate change.” He adds, “We should not spend vast amounts of money to cut a tiny slice of the global temperature increase when this leads to a poor use of resources and when we could probably use these funds far more effectively in the developing world.” For saying this, Lomborg has had death threats.
Other scientists who do not toe the global warming-is-happening-and-it’s-all-our-fault line have received the same. There are plenty of people who count against global warming. A world of senior climatologists and meteorologists wrote to the Times last year to plain that they couldn’t get their research findings published — because they disagreed to it. We have had a warm autumn. The experts,  fanatics（狂热者） all of them, put it down to global warming. If we have an extra cold winter, they will tell us it’s a result of global warming. If my big toe feels cold or hurts badly, it will be owing to global warming.
