Next time you hear someone make this dumbass comment in the real world, please show them this video.
Other than the regrettable joke at 0:40, this is some solid climate info disguised as sketch comedy. Listen. Learn. Laugh.
Planet Victory Climate Change
If you're unsure whether this comedy sketch got its facts straight, allow me to quote NASA: "The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere 'behaves' over relatively long periods of time."
And you can't argue with NASA 'cause, you know ... they're NASA.
