The polar vortex has become a trending topic among SLA’s youth, staff and faculty. However the majority of us were at a loss as to how we could explain this natural phenomenon. So in this predicament we call on one of SLA’s very knowledgable and nerdy teacher Matthew Vankowenberg to explain the logic and science behind this mystery.
“ The usual reaction of those who don’t understand global warming is “WOW IT’S REALLY COLD GLOBAL WARMING MUST NOT BE HAPPENING!” and those people are stupid. What is the first word in global warming?” The class does not fail to answer in unison with “GLOBAL” “Exactly! Meaning that in most parts of the globe it is getting warmer, Not just AMERICA! This cold weather actually shows a variation. A few days ago in Australia the temperatures reached about roughly 130 degrees fahrenheit! and what happens to things when they heat up? They expand, and when as things get cooler they contract meaning they are more dense. As the earth revolves the poles do not move at all in terms of miles. The top and bottom a sphere you find barley move from position at all! However the different seeds of rotations with the densities creates what we call the jet stream. So the warm air is separating from the cold air because of the differences in density. Then you have the components of direct sunlight energy and direct heat energy, and we also know that there has to be some heat trapped between the two. The equator gets more direct sunlight so the poles rely more on the trapped sunlight and heat energy. So the poles are warming up. So if the poles started lower and increased more in terms of temperature how is there a temperature difference? No there is not as much of a temperature difference meaning there os not as much of a density difference so there is a huge weakness between the poles. So in addition to being weak, it’s all over the place. So the air is traveling. So now there’s too much air up above and therefore it forced cold air down.
