In case you haven't noticed, the weather has been--shall we say--unusual.
The average high temperature for International Falls, MN, in January is 15 degrees Fahrenheit.
Last Wednesday it was -36.4 with a windchill of -58.
This week, temperatures are predicted to spike 80 degrees.
"In the beautiful Midwest, windchill temperatures are reaching minus 60 degrees, the coldest ever recorded. In coming days, expected to get even colder. People can't last outside even for minutes. What the hell is going on with Global Waming [sic]? Please come back fast, we need you!"
What the hell is going on with global "waming?"
What the president doesn't care to know (despite having access to every top climate scientist in the world) is that all these dangerous meteorological aberrations are because of global warming, aka climate change.
That's why places where it's hot are hotter than normal; places where it's cold are even colder, in some places, than at any other time in recorded history.
According to the National Oceanic and Atmospheric Administration (NOAA), 2018 was the fourth warmest year for the planet.
This doesn't mean, despite what our president says, everywhere is going to be stifling hot all the time.
According to a study released in Geophysical Research Letters, a publication of the American Geophysical Union, the shifting jet stream is responsible for dramatic temperature swings, causing glaciers in western North America to melt four times faster than in the last decade, creating what we now know as a "polar vortex"--a term familiar today but virtually unknown to most only a few years ago.
The polar vortex is a frigid air mass concentrated in the Arctic that traps cold air.
