Comment Re:CO2 levels correlated with sea level rise? (Score 1) 126

You can see the slow rise better with the larger graph from that page. https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2F...

No, you can't. That graph shows the rise over the last 24,000 years, but your claim was about last 2000 years, and on that curve the last 2000 years are flat. The curve I linked from the same Wikipedia page is a blow-up of the same data over just the last 2000 years, and shows more clearly that it there is no increase visible over the last 2000 years.

My point is that we are in a post glacial period with slow sea level rise.

And my point is that the data you linked shows that we are in a post-glacial period after the glacial-melt sea level rise.

Now compare the linear sea level rise in the tide gauge data to the exponential CO2 level rise

There's your problem right there. First, CO2 rise is not exponential, and second, you seem to be assuming a model saying in which sea level should be linear in instantaneous CO2 concentration.

Dealing with the first point CO2 concentration in the air is an exponential plus a constant . Look again at the CO2 graph and look at the y axis. That constant is critical, because delta temperature is not linear in CO2 concentration; it is proportional to the logarithm of greenhouse gas concentration (this is why climate sensitivity is always quoted in degrees per doubling.) So the constant is a critical factor. This has been known since Arrhenius. Basically, since we haven't even hit doubling yet, we're still on the linear part of the curve.

and from predictions we should see a curve upward in sea level and we don't. CO2 levels really took off during WWII and here 75 years later we are not seeing the exponential rise predicted.

Yes, as for the second factor, what model of glacial melting are you using to ground your hypothesis that glacial melt rate and subsequent sea level change should be proportional to CO2?

Found a tide gauge in San Francisco with a longer history for further reference: https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2F...

Overall, I'd say that the data is not over a long enough time scale and is too noisy to accurately measure the second derivative of the curve. And, overall, you want global sea level, not one or two selected spots. There's good satellite data on that now, but the time scale is too short to measure second derivative.

If the ocean rises then it rises. You can't cherry-pick a beach and say that the height of the ocean is an outlier in that area.

Actually, you can. Sea level is not uniform, and sea level rise is even more not uniform. Yes, the sea level can rise a lot in one place, a little in another place, and not at all in others. So, yes, some places will be outliers high, and some outliers low. On the average, however, sea level is rising.

And it's all complicated by the fact that in places the land is subsiding, in others it's rising, and in some places parts of it are rising and others sinking.

Take a look at real sea level rise at https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Ftidesandcurrents.noaa.... Now take a look at the historical sea level rise at https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2F... and note the Post Glacial sea level rise, sea levels are rising but slowly and consistently over the last 2000 years.

OK, I did what you asked. Click on the Post Glacial sea level rise graph in that wikipedia article and you see it in more detail: https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fen.wikipedia.org%2Fwiki%2F...
Contradicting what you stated, the graph shows no sea level rise over the past 2000 years (although it doesn't have enough detail to show the most recent 30 years discussed in the article.)

How does one explain those timelapses of satellite imagery of beaches that show the exact same sea level over 20 years?

Citation needed as to exactly what image. An overall discussion is here: https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.usatoday.com%2Fstory...

Comment Not news (Score 0) 126

Not really news; we've known for a long time that the sea level is rising, and that global warming is contributing to this. The interesting thing about this article is that it does acknowledge the uncertainty in estimates, something that's often missing from science popularizations.

This is a long-term effect. Don't expect New York to be underwater in the next decade, or the one after.

You really think that buying one cup of coffee means you ought to get a table at the coffee shop as your personal remote office all day?

Maybe if you're there at a slack time, when plenty of tables are free, but if you're hogging a table for hours and hours when other people can't sit down, you're a moocher.

That changes nothing.

It "changes" nothing, but it does point out that your comment is irrelevant to the post you were responding to.

But if the top, say, ten CEOs are paid $101.5 million, and the next 90 are paid nothing at all, the average pay of a CEO is over a million dollars, even though most of the CEOs are unpaid.

Congrats, you pointed out the basic issue with using averages.

You were the one who gave an average. I was just pointing out the flaw in that.

I know of a lot of University programs that are only open to US Citizens, but don't know of any US university programs that are available only to foreign students.

...Where the whole thing gets skeezy is how the college is get paid. It's loans from the federal government but if the students get out of college and the businesses decide they've had enough for used them up The students go back to their country and never pay the loans leaving the American taxpayer on the hook for it.

Federal student loans are not available to international students.

Comment Deep water [Re:My 2 cents on this one.] (Score 1) 29

I see the model inverted. The water is deep in the centre from the outset. It takes a long time for the water to escape to the surface. Just like it takes a long time for heat to also escape.

Not at all unreasonable; several geophysicists have suggested that the Earth has a lot of deep water bonded to the mantle rocks; and possibly more water deep than there is on the surface.

Do keep in mind that the Earth is quite well differentiated, so unless the water is dissolved in the mineral at equilibrium concentration for the pressure and temperature, it will have differentiated out (which, because it's so low density, means to the surface).

Comment H2S [Re:My 2 cents on this one.] (Score 3, Informative) 29

When viewing simulation of planetary formation, many times, there is a vast accretion disk around the planet for some time. Especially in massive body collision simulations. The one that Created the moon for example, would have left the crust molten for 50,000-200,000 years. That water would have had to have been in gas form, (an Entire Global set of Oceans worth.) for all of that time. I cannot see that much water floating around as clouds.

The suggestion here was the hydrogen was not in the form of water, H2O, but in the form of hydrogen sulfide, H2S. Which is also a gas, but the hypothesis here is that the H2S is dissolved in the molten silicate of the accretion disk. https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fdoi.org%2F10.1016%2Fj.icar...

Not mentioned in the abstract is how this leads to water (*), but presumably after the Earth cools a bit, the H2S outgasses from the silicate rock (possibly as volcanic or thermal vent emissions) and reacts H2S + O2 --> H2O + SO
(and the SO then goes on to oxidize further into sulfate).
