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
...it is coming now. This time, the jet stream - again, which has been changing because of a warmer climate - is moving toward the east coast. So, temperature plunges, snow. So, warming at poles is causing cold air cycling around the poles to move through the United States..../6
...now, there is also the fact that weather is not climate. Is this one episode a direct consequence of warming? That will require research. No single weather event shows climate. But this does show why saying "haha! Snow! Global warming!" is stupid. It is why the term.../7
...global warming had to be changed to climate change, because arrogant, anti-science conservatives were too stupid to understand that a warming earth leads to extreme weather events, not just "the weather in the whole world is hot at all times." But even changing the term.../8
...to reflect more of a layman's understanding didnt work. The conservatives just said, "HAHAHA! They changed it to climate change from global warming because it snows sometimes!"

Can't reason with stupid and arrogant.

THREAD: 12 Things Everyone Should Know About IQ

1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE


2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less.
https://t.co/UqtS1lpw3n


3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)

(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)


4. IQ predicts many important real world outcomes.

For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3


5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)
A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.

Legacy site *downloads* ~630 KB CSS per theme and writing direction.

6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors
46 unique font sizes
39 unique z-indices

https://t.co/qyl4Bt1i5x


PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.

735 rules
740 selectors
757 declarations
730 unique declarations
0 media queries
11 unique colors
32 unique background colors
15 unique font sizes
7 unique z-indices

https://t.co/w7oNG5KUkJ


The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.

The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
