Great to see it. Those look very nice!

Grass would be more of a hassle. Once the plants have properly rooted down, the tracks shouldn’t need any watering or routine cutting. I’m guessing that the trams themselves prevent most of the plants from growing too long. As can be seen in the first picture there, the plants between the rails are shorter than those between and outside the two tracks.

An extreme value is always only extreme in relation to some baseline. For temperatures it’s usually a value that departs far from the local average. With WBT it could mean values that approach the limit of what the human physiology can handle, a value that is quite universal due to us all being of the same species. The body cannot adapt beyond the limits set by thermodynamics.

Tropical and extreme aren’t mutually exclusive. +30°C in Antarctica would be both tropical and extreme. Both are used where applicable. A temperature can also be extreme without being tropical. No matter what Trump thinks, he doesn’t have the power to redefine words.

*Extreme WBT’s

A wet bulb thermometer measures wet bulb temperature (WBT), which exists always as long as there’s any humidity whatsoever in the air. It only gets bad when the WBT reaches an extreme value, as is the case for basically all environmental metrics. Saying that wet bulb temperature is lethal is like saying that temperature is lethal. Look out for temperature! I’m sorry for the rant so I’ll try to keep this short, but “wet bulb” by itself in this context is an inane shorthand that lacks all the significant words and muddles the meaning of those words that are in it. Scientists talk about Extreme WBT events, because that’s what they are.

Nice! Altocumulus stratiformis undulatus, but with two intersecting systems of undulations. Think of them like cross waves at sea.

Oh, right. I figured that a person using a screen reader can probably see that one by themselves, but I suppose I could throw that one into the post body as well.

Thanks for the reminder!
