14 DAY TRIAL // It's pretty cold in the United States, and climate change deniers are having a field day. Thus, they keep going on and on about how, given the stunningly low temperatures recorded in the country, global warming cannot possibly be anything but a carefully constructed hoax.
This past Wednesday, the Obama administration decided to set the record straight and released a new video explaining what the deal with the polar vortex was, and why its hitting the United States so hard did not in any way prove that global warming was not real.
The video, made available to you at the end of this article, features Dr. John Holdren, the current director of the Office of Science and Technology Policy, Huffington Post tells us.
The specialist begins by pointing out the fact that, contrary to what some people might think, a single weather event cannot be used to draw conclusions concerning either climate change or global warming.
“If you’ve been hearing that extreme cold spells, like the one that we’re having in the United States now, disprove global warming, don’t believe it,” Dr. John Holdren says.
“The fact is that no single weather episode can either prove or disprove global climate change,” President Obama's science advisor goes on to explain.
According to Holdren, global warming is causing the Arctic to heat up about twice as fast as mid-latitudes. Due to the fact that the temperature difference between the Arctic and the mid-latitudes is shrinking, the polar vortex changes.
More precisely, it weakens. Hence, masses of cold air get to travel all the way to the mid-latitudes.
Otherwise put, the historic cold snap currently affecting the United States not only does not disprove global warming. On the contrary, it confirms it.
“A growing body of evidence suggests that the kind of extreme cold being experienced by much of the United States as we speak is a pattern we can expect to see with increasing frequency, as global warming continues,” Dr. John Holdren says.
