It's #FigureFriday, so let's chat about my favorite subject: color palettes 🎨 for climate science visualization! (1/12)

First, why is it important? Put simply: a beautiful figure can communicate your results more effectively than text. It can make a figure more understandable to a public audience. So it is worth it to put care into your figure design. (2/12)

First, if you're plotting up climate model data, especially anomalies, I highly recommend Cynthia Brewer's palettes on ColorBrewer. BrBG is my go-to for precip anomalies, and RdBu is a natural for temperature. (3/12)

The sequential palettes are also great if you've got data going in one direction. Here's the Brewer "blues" at work for a figure showing LGM T change. (4/12)

But what about line graphs? If you are paleoclimatologist like me, you are probably plotting a bunch of squiggly lines. For this, I suggest designing a palette for your *entire paper* ahead on time, and then plot stuff in this palette in every figure. (5/12)

There's a huge gap between what climate scientists are willing to say privately and what we're willing to say publicly, in terms of how dire a situation we're in. Colleagues, integrity demands we close this gap.

Now, before the stupid conservatives begin sneering and laughing AGAIN about climate change and a massive snowstorm, one more time trying to educate:

A warming climate causes extreme weather events, *including* huge snow and plunging temps. 1 example why: (Note: I realize.../1

...that no matter what is said, anti-science and arrogant conservatives who failed high school science will still sneer and laugh because this is more complicated than "temp goes up, it gets cold. HAHAHA!" Plus, they don't wont read anything longer than 20 words. But this.../2

...will at least help reply to their foolishness.)

Here is what is happening right now: there is a large area of low pressure and cold air at both poles. That cycles around the poles and is contained there by higher pressure surrounding it. However, a warming planet changes.../3

...that. The higher pressure/low pressure contains the cold air, but as that warms, what essentially serves as a fence weakens. Plus, simultaneously, the warmer climate is changing the jet stream. Even before this, sometimes the contained area expanded and hit the jet stream.../4

...which brought the polar cold down, thus plunging temperatures. However, with a warming climate - because of the change in pressures and the moving jet steam - the polar air is coming down more frequently. A few years back, *Texas* was hit by polar air. That's how far down.../5
