So in the last month we've had three instances of temperature shifts between low-40s and single digits in a span of less than 36 hours. And if I hear one more person say "hurr hurr I guess that shows those climate scientists a thing or two", I will KILL. Because seriously, you shouldn't speak about things you don't understand. This weather is evidence of global warming - it makes every kind of weather more extreme and variable. Summers are hotter, winters are colder, droughts are drier, monsoon rains are wetter, hurricanes, tornadoes, and thunderstorms are stronger and more dangerous.
So, science. Get some.
