RE: rising sea levels




Funny it says "altering habitat now suited for crabs, shrimp and fish" but doesn't mention the almighty plovers




RE: rising sea levels




Yes, interesting and sobering.


RE: rising sea levels




see, the speculative prospecting for $$$ was happening even way back when.


RE: rising sea levels




Do you have a good link to the article? The one in the Op doesn't work. It's hard to comment about it when I can't read it. 11 years isn't very long when talking about sea level though.

Yes, John, it is. We were told back then we would have a foot rise by 2030, you yourself have said it is now being measured in millimeters.
As for the link, that would be up to the Charlotte Observer archives. I was only reading and responding back then. As I recall it was a federally funded UNC study with a prescribed outcome.
Please go back in time 90-100 pages on this message board forum. It is very revealing. There was discussion, confrontation, conflict, but a lot of civility as well. A lot of interesting reads and history from a lot of well-informed legacy members who are either here occasionally, or have left or passed. Oh, the names and faces I could put with some of those posters on both sides of the debates.

How does a 30-year timeframe grab you?

Theory:

[i][b]Global mean temperature will likely rise at about 0.6 degrees Fahrenheit per decade and sea level at about 2.5 inches per decade over the next century. These rates are 3 to 6 times recent historical rates. (emphasis mine)

- Dr. Robert Oppenheimer, June 23rd, 1988, part of Congressional Testimony[/I][/b]


Reality (In graph below, source: NOAA):

[I][b]Notice that the rate of sea level rise is 2.8 millimeters per year (1.1 inches per decade), less than half of what Dr. Oppenheimer predicted. More importantly, notice that the rate of increase has been pretty constant, despite the fact that the carbon dioxide concentration in the atmosphere rose significantly during that same time period.[/I][/b]

Dr. O’s testimony was given at the same hearing where NASA’s Dr. James Hansen gave testimony that is historically considered to be the start of the Anthropogenic Global Warming er, ummm, “movement”.

Dr. H’s dire predictions failed just as spectacularly. We can delve into his body of work also if you so desire.

I'm not sure who told you that, but I haven't read any of those reports. They would of course be wrong for global measurements. I guess it would really help if that article link worked.

It's standard to use the metric system in scientific reporting, so I'm not sure what your millimeters comment was about. It's not now being measured that way, it always has.

RE: rising sea levels




Sea level rises faster in some locations than others due to "land subsidence", the sinking of land. This occurs more in coastal areas than bedrock areas. Why? It is caused by the compaction of sediments caused by natural effects and groundwater withdrawal.

This is absolutely true. It happens in reverse as well. For example, Juneau Alaska's sea level is actually dropping because the land is rising at a faster rate than the sea level. That's why they use averaging and look at it globally instead of locally.

Agree and think since the natural forces of land subsidence is the primary cause we should cease referring to this natural, non-man made effect as "sea level rise" and call it what it is - subsidence. It would take the political drama out of the di$cu$$ion.

Please note that hatteras island water association water is provided by reverse osmosis of seawater, not deepwell sources, and that "groundwater" is not drawn anywhere I am aware of as a potable water source.

You are correct, sir! Well, mostly. Sea levels aren't rising faster in some locations, as the sea rise metric is global and stable, where subsidence is local and variable.

Land subsidence aside, NOAA's data shows that sea levels are rising at 2.8 millimeters per year, or 1.1 inches per decade, which is less than half of what Dr. Oppenheimer breathlessly predicted back in 1988.

No reason to panic, we're still in the same Holocene Interglacial Epoch that we have been for the past ~12K years.

We have a huge aquifer in Buxton Woods and South which is why there are zoning mods within that special water district. Pretty sure the ability to pump that still exists but agree we use mostly reverse osmosis.

Exactly. See graphic below, 2.8mm/annum, which has been stable at that rate for the entirety of modern record keeping, all despite the prophet$ claiming gloom and doom are upon us.
