Trump, the scientist's nightmare, displays his abysmal ignorance of what a polar vortex is.

Start by reading about what the polar vortices are.

The vortices weaken and strengthen from year to year. When the vortex of the arctic is strong, it is well defined, there is a single vortex, and the arctic air is well contained; when weaker, which it generally is, it will break into two or more vortices; when very weak, the flow of arctic air becomes more disorganized and masses of cold arctic air can push equatorward, bringing with it a rapid and sharp temperature drop.

Scientists are always cautious in their conclusions, but...

The general assumption is that reduced snow cover and sea ice reflect less sunlight and therefore evaporation and transpiration increases, which in turn alters the pressure and temperature gradient of the polar vortex, causing it to weaken or collapse. This becomes apparent when the jet stream amplitude increases (meanders) over the northern hemisphere, causing Rossby waves to propagate farther to the south or north, which in turn transports warmer air to the north pole and polar air into lower latitudes.

And now this:

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? Please come back fast, we need you!


Today's depressing reality actually makes this XKCD cartoon about science denying politicians seem tame in comparison.

and climate change can be explained in a fucking animated cartoon format!

Why haven’t scientists and believers done this!?

They explained WWII as it was happening in animated film and showed it in the movie theaters as news shorts. It’s not like the medium is a hard concept to grasp.

Fuck!
