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.

Grassy trams are better than dead asphalt, but monoculture lawns are still not the best. I'm not sure what the best translation of the official name would be, but I guess meadowy tram would fit. Much lower maintenance and increased resilience to heat and dryness are nice bonuses.

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 can also 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 (let alone erase) words.
The wet bulb temp. in a proper sauna should get quite high, I don't have exact numbers but above 70°C or so (dry temp. 90°C, relative humidity 50% would translate to a WBT of 74°C). In most contexts that would be extreme, but not here.
*Extreme WBT's
A wet bulb thermometer measures wet bulb temperature (WBT), which is a metric that always exists and can always be measured. 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. A less of a mouthful would be nice for science communication, but I don't want it to come at the expense of words losing meaning like that.
Heatwave is a nice and descriptive word for one type of an extreme temperature event. Cold snap is another one. I'm glad neither is called "temperature event" because that would be dumb.
They sure don't tend to do that, but there are still mundane explanations for this. An unintentional collision between the satellite and another object being one of them.
"I find it hard to believe they would use such a big satellite as an ASAT target," McDowell said.
Not because of Kessler syndrome, just your run of the mill space debris reentering the atmosphere and increasing the amounts of certain metals up there that contribute to ozone depletion. In other words, that may well happen even if we're lucky and avoid Kessler syndrome.
Cirrus and Cirrostratus progressively invading the sky are a telltale sign of an approaching warm front. In this case it was an occluded front that was rolling in. It snowed that night.
Don't be decieved by the anvil like shape, heavy looking precipitation and icy look of this cloud! This is far from the size and power of an actual Cumulonimbus. But it is interesting in that it fits every criteria of a Cumulonimbus capillatus incus, except the bit about considerable vertical extent for the genus. I'm quite sure that this guy didn't raise its head much above 2 km AGL.
I suppose it could be classified as a Cumulus of some sort, but it really doesn't fit well under any genus. Our systems of classification are just something that we made up. Clouds are under no obligation to conform to them. The same is true for everything else in the universe as well.
Almost forgot to get back to you about that last part: Yes it did, but this wasn't that.
Here's a picture I took when the smoke was making a sunset unusually red:
This was a telephoto at the horizon at around midnight. The sun was only a bit above the horizon, so the lighting was similar to a sunset/sunrise.
Here's another picture of that same midnight, looking towards the sun.
Thanks!
You're welcome!
Picture taken in August 2022. Fluctus, also known as Kelvin-Helmholtz wave clouds, form when wind shear causes instability in the (usually the upper) surface of a cloud. The formation is short lived and relatively rare. It can also only be seen well from the side like here. This video contains a good explanation of the physics involved here.

Thanks for notifying. Should be fixed now.
Thanks! That day was beautiful.
