That's the part I feel worst about. The cast is giving 110%, the people doing the stunts, effects and production design are doing the best work of their lives. The music and directing is better than anything else on tv. But all of their insane work is being wasted on bad scripts.

We don't know the real word for bear. The word "bear" literally means "the brown one". It was used in ancient times because people believed that using the bear's true name would summon it. The taboo was so effective that the original name was lost and we were left with "bear".

Significant growth in wind but primarily natural gas. Not perfect but around half the CO2 per kWh compared to coal so certainly a massive improvement.

I love how hypnotic this animation of atmospheric humidity turned out! This was also a fun chance to try a new visualization trick: While humidity drives the color ramp, the brightness is modulated based on windspeed, which seems to give the whole thing more structure.

I get that way about places. Like the city I used to live in kind of exists in two ways for me now. There’s the real, changing place that I don’t think about, and the place in my mind that’s frozen in the state it was in when I left.

My idea is that they should have qualifications as usual, and then reassign all the sports at random at the opening ceremonies. You placed first in qualifications for weightlifting? Now you're a rhythmic gymnast.

The reason they don't take more frequent images is because the things they're measuring (global weather patterns) aren't (usually) subject to extremely rapid change. So they spend their data budget on resolution rather than frequency.

And it's weird that it gets reasonably close with the spelling too. You'd think that if it doesn't understand text at all it would spit out total gibberish, but it seems to get like 90% of the way there before it loses the plot.
