Cold winter day as an example of what a cold snap can look like; cold snaps (cold spells or extreme cold) can happen during global warming

Cold snaps during global warming are not actually a paradox, here’s why

Why do cold snaps happen if the Earth is warming? Cold snaps are part of Earth’s natural climate variability. However, global warming is causing winters to get warmer, and making cold snaps less frequent or less intense over most land areas globally since 1950.

PragerU post by Happer uses flawed reasoning to claim that climate models always fail

"climate models that attempt to predict the future temperature of the planet...don’t work. They haven’t worked in the past. They don’t work now."; "the number of factors that influence climate—the sun, the earth’s orbital properties, oceans, clouds, and, yes, industrial man—is huge and enormously variable"; "CO2 is a minor contributor to the warming of the earth"
