This fluid, seemingly at rest initially, turns out to be convecting as revealed by a movie. cools the fluid at the surface, which makes it a bit heavier than the fluid below, thus ensues, very slowly!

This fluid is , easy to make at home using shaving cream.

Black holes do not die per se, but they are theoretically predicted to eventually slowly evaporate over extremely long time scales.

This is a very interesting proposal; hope there’s good analysis and documentation about rates. It’s clear that Nature has developed some systems for atmospheric modulation and humans do well when we work within . It also makes sense to build infrastructures such as over existing canals and hard scape , walls. mastodon.tucsonsentinel.com/@T

“That means that objects without an event horizon, such as the remnants of dead stars and other large objects in the universe, also have this sort of radiation. And, after a very long period, that would lead to everything in the universe eventually evaporating, just like black holes. This changes not only our understanding of Hawking radiation but also our view of the universe and its future.” ~ Heino Falcke

5/34 Another one doesn't get as much attention as some of those do. It's this: your home's air will feel more at a given temperature and humidity if it's moving.

When , air movement keeps the air from stratifying, leaving a cold layer near the floor that makes your feet feel like they're freezing.

When cooling, it also does that, but in addition, moving air is better at evaporating from your , which increases the cooling effect of that .

After the rain.

The rain water that formed a broad but shallow silty pool in a desert hollow is rapidly evaporating under a hot sun. The surface is breaking into leathery leaves that curl at the edges, exposing a dessicated sandy soil beneath.

Will Japan release Fukushima water into the Pacific?

Officials in Japan have claimed that water exposed to radiation in the Fukushima nuclear disaster is now safe to dump into the Pacific. Environmentalists say the water is too contaminated.

by Julian Ryall , November 20, 2019

" and the government [of ] have long believed that the best way to dispose of the water is to simply release it into the . They claimed until this year that contaminated water had been cleansed by a so-called advanced liquid processing system to the point that virtually all the radionuclides had been reduced to 'non-detect' levels.

"Leaked TEPCO documents, however, show that varying amounts of 62 radionuclides — including , , and — have not been removed from the water.

"The company has also been criticized for refusing to permit independent organizations to test the water that is being stored at the site.

"Nevertheless, environmentalists fear that preparations are under way to release the water into the environment.

"'Even a year ago, when the first report on options for disposing the treated water was presented to the committee, it seemed clear to me even then that the preferred option was to release it into the ocean,' said Azby Brown, the lead researcher for Tokyo-based nuclear monitoring organization Japan. Other options included and burying the water.

"'My take on this is that they have already reached a decision and that all these discussions now on the options are purely theater.'"

Because of physics.🤭
Although your coffee won't cool (very slightly) below room temperature, if the air in the room is saturated with water vapor.

Here’s a wild bit of data:

“In a 100-year period, a water molecule spends 98 years in the ocean, 20 months as ice, about 2 weeks in lakes and rivers, and less than a week in the atmosphere.”

From lenntech.com/water-trivia-fact

When I’m thinking of the , I almost always am focused on those parts that directly effect me, a human. So I’m thinking about , about , about , about . I’m seldom thinking about the . But to think about water is to think about the ocean. To water itself, its forays into land-based activities are a miniscule part of their existence.

I wonder if those two weeks as lakes and rivers are some kind of water vacation, once in a hundred years, where they get to see the world? Or is it that the ocean itself is so vast that moving through it as a water molecule is to be experiencing the wonder of a thousand million different things on an ongoing basis and time on land is some kind of dried up, confined penance?

Water is the ocean. The rest of it is an afterthought.

The African continent is experiencing disastrous problems due to the even though it has contributed only minimally to the greenhouse gas emissions that have caused it.

In the region in particular, erratic rainfall and increased have led to , which causes repeated failures and the disappearance of vegetation for grazing livestock.
