The severe cold that hit the United States has fueled climate change. Theories have been voiced: "Given the incredibly low temperatures recorded in the country, global warming could possibly be nothing more than a carefully crafted prank."
On Wednesday, the Obama administration decided to put things in place and released a new video explaining the phenomenon of the polar vortex, and why the hit in the United States in no way demonstrates that global warming was not real .
In the video, which you can see at the beginning of this article, Dr. John Holden, ο σημερινός διευθυντής του Γραφείου της Επιστημονικής και Τεχνολογικής Πολιτικής του Λευκού Οίκου των ΗΠΑ, μας αναφέρει ότι σε αντίθεση με ό, τι μερικοί άνθρωποι μπορεί να πιστεύουν, ένα μεμονωμένο καιρικό φαινόμενο δεν μπορεί να χρησιμοποιηθεί για την εξtreatment conclusions regarding climate change and global warming.
Specifically, the Dr. John Holdren says: "If you've heard that extreme cold waves, like the one we have in the United States today, disprove global warming, do not believe it. The fact is that there is no single weather episode that can either prove or disprove global climate change. "
And President Obama's scientific advisor goes on to explain that global warming is causing the Arctic to warm up about twice as fast as the average latitudes. Due to the fact that the temperature difference between the Arctic and the average latitudes is shrinking, the polar vortex changes. More precisely, it is weakened. Therefore, the masses of cold air can travel all the way up to the middle latitudes.
In other words, the record cold that is hitting the United States today, not only does not negate global warming but on the contrary, it confirms it.
"More and more evidence is showing that the extreme cold weather facing much of the United States as we speak is a pattern we can expect to see with increasing frequency, as global warming continues," says Dr. John Holdren.
