Smog checks and CARB going away!

NASA and the NOAA do NOT fuck around. We can measure distance to Earth with a few milimeter accuracy.

We are technologically capable of measuring distortion of space-time 1/10,000 the diameter of a proton to locate black hole collisions. It's called LIGO. This is where we are at as a society.

Yes, the ground sinks for many reasons and many are outlined in the link above.

You did not answer my question! Where did all this water come from?

Who the hell cares about black hole collisions? It doesn't impact my life in any way, shape or form!

Happy Labor Day fellas. 👍

His point was, if the land was sinking, we could measure it. Relative to measuring interactions on an atomic level, this is trivial. I believe those were his points?

Interestingly, the Earth continues to loose "small" amounts of water to space.

But in reference to the water origin question, I've heard the comet theory. Besides being in the "Goldilocks Zone" for temperature, we have the right amount of gravity and an atmosphere that retains it. Mars has neither the gravity or the appropriate atmosphere for retaining it, longer term.

I'll watch this at double-speed. Should be interesting... 😎

Intuit got it. This is trivial stuff. The hard part is predicting at a local level. The link shows that thermal expansion of the water and the addition of fresh water from melting ice. It also talks about subsidence which is a fascinating thing to read about.

Let me throw this out there, so if the land is subsiding they could say that the oceans are rising! Pse explain how some of the ocean(s) are only rising and not others when they are all connected in one way or another. I don't believe the stuff about melting ice raising levels. It doesn't work in a glass full of ice and water! The glass does not overflow!

This is correct, glacier melt in the ocean does not contribute much. It does very little in the same way as ice in a glass as you described above (minus the addition of freshwater and other things).

The vast majority of the melt rise comes from land ice from Antarctica and Greenland; not glaciers that are already in the ocean.

Once again, no-one has answered why some oceans 'rise' and others do not. I would imagine that measurements are only taken when the oceans are virtually flat with no waves, otherwise the height would be fluctuating every time a measurement is taken!

The article prefaces the following by bring up some potential ways how this information can be effectively used to better manage water resources.

<< ............Satellite data drives research of heat in oceans and lakes. Studying river temperatures is more difficult because it’s reliant on stream-gauge sensors that are often in and out of service, leaving data gaps that can be hard to parse.

For the new study, the researchers collected data from 1,471 United States Geological Survey stream monitoring sites from 1980 to 2022.

The data allowed the researchers to assess changes in streams nationwide. They found that riverine heat waves in 2022 were happening more often than in 1980 — with an average of 1.8 additional heat wave events taking place per year. The heat waves were also more intense, with temperatures during heat events about .8 degrees Fahrenheit higher, on average, in 2022 in comparison to 1980. Heat wave events lasted more than three days longer than in the past.

Li said the additional heat is causing about 12 more days of heat stress, on average, for species that need cold water. The study’s authors used 59 degrees F as its threshold for heat stress because some species, like bull trout, struggle to survive at about that marker. ............ >>
