?and it’s our fault – No matter how cold this winter has been, the truth is: The world is getting warmer. Scientists studying climate change have long believed that while most of the rest of the globe has been getting steadily warmer, a large part of Antarctica?the East Antarctic Ice Sheet?has actually been getting colder. But new research shows that’s not true?the whole earth is warming up, and we can’t blame it on sunspots: Alas, it’s our fault.
Researcher Eric Steig says, “Simple explanations don’t capture the complexity of climate. The thing you hear all the time is that Antarctica is cooling and that’s not the case. If anything it’s the reverse, but it’s more complex than that. Antarctica isn’t warming at the same rate everywhere, and while some areas have been cooling for a long time the evidence shows the continent as a whole is getting warmer.”
While the harsh winter pounding many areas of North America and Europe seemingly contradicts the fact that global warming continues unabated, a new survey finds consensus among scientists about the reality of climate change and its likely cause.
When a group of over 3,000 earth scientists around the world was surveyed, they overwhelmingly agreed that in the past 200-plus years, mean global temperatures have been rising, and that human activity is a significant contributing factor in changing mean global temperatures.
There was near-unanimous agreement by climatologists, with petroleum geologists and meteorologists among the biggest doubters. Researcher Peter Doran has an explanation for this: “The petroleum geologist response is not too surprising, but the meteorologists’ [who are the weathermen we see on the TV news] is very interesting. Most members of the public think meteorologists know climate, but most of them actually study very short-term phenomenon.
“[Climatologists are] the ones who study and publish on climate science. So I guess the take-home message is, the more you know about the field of climate science, the more you’re likely to believe in global warming and humankind’s contribution to it.”
