    Source: Study finds record-breaking rates of sea-level rise along the U.S. Southeast and Gulf coasts

    . . .
    In the study, published in Nature Communications, researchers said they had detected rates of sea-level rise of about a half an inch per year since 2010. They attribute the acceleration to the compounding effects of man-made climate change and natural climate variability.

    "These rapid rates are unprecedented over at least the 20th century and they have been three times higher than the global average over the same period," says Sönke Dangendorf, lead author and the David and Jane Flowerree Assistant Professor in the Department of River-Coastal Science and Engineering at Tulane.

    The authors studied a combination of field and satellite measurements since 1900, pinpointing the individual contributors to the acceleration.

    "The scientists suggest that the recent acceleration was an unfortunate superposition of man-made climate change signals and a peak in weather-related variability that lasted over several years. They conclude that the rates will likely return to the more moderate values as predicted by climate models in the coming decades."

    Outside certain areas of rapid land subsistence, such as coastal TX and Louisiana, very few of our old fogey generation will need to move. But the children and grandchildren may decide that numerous properties we may be intending to bequeath to them, won't be worth attempting to save or maintain.

    the thing is, coastal properties will go down in value, and inland (especially at higher elevations) will go up.
    best to sell the coastal now at high prices, and buy the inland at low prices. bequeath the difference to your aires.
    sell low and buy high :cool:

    or just wait for elon to settle us on mars, no oceans to worry about :)

    Pretty sure I'm not in the billionaire frat boy demographic that'll end up settled off Earth.

    Do it very soon, while there is still a good supply of buyers who don't believe that sea level will meaningfully rise.

    Prices of inland properties will continue rising regardless of sea level rise. They were rising before sea level rise was noticed or thought about.

    A much longer and more detailed article appeared here today:

    Seas have drastically risen along southern U.S. coast in past decade | The Seattle Times
    (republished from Sea level rise along southern U.S. happening faster than previously thought - The Washington Post)

    The Gulf of Mexico has been warming much faster than the global ocean. Not just near the surface, but down deep too. As water warms, it expands, causing more sea level rise. This warmer gulf water flowing out and up along the East Coast also has impacts there.

    WE will be lucky to see humans revisit the Moon in a more meaningful manner than just leaving some litter behind.
    Researchers believe that Mars once had a global magnetic field, like Earth's, but there are no Priuses on Mars.
    That means that there was and IS nothing to mitigate that planet's climate change, and thus it's a little more challenging for humans to settle there, but fear not!
    The Moon ALSO lacks Priuses AND a magnetosphere, despite the fact that 100% of the cars there are BEVs....so if we ever get to the point of using it as a 'jumping-off' point then we might get some practice in mitigating some of the challenges of "life out there."

    As far as terrestrial land values?
    I once visited the Falls of the Ohio in my beloved home state of Indiana.
    They have some pretty interesting fossil evidence there that the Earth's climate might be a little more dynamic than we wee humans might appreciate.
    They used to have some coastal property THERE too! ;)

    I'm pretty sure you meant to say:
    • moon - airless without modern civilization, observatories on the far side of the moon will be free from all but solar winds/storms and solar EMI noise. Manufacturing rocket fuels on the moon is unlikely. But shorter distances makes human visits possible.
    • mars - thin atmosphere and no magnetic field means little protection from solar wind and storms diluted by distance. The CO{2} and water makes manufacturing rocket fuels possible. But longer distances makes human visits more challenging.
    • BEVs will be the surface travel vehicles of choice. However, a hopping vehicle may be more practical than wheels on the moon. Regardless, one Tesla has been sent towards Mars.

    ... back when we, and much of the flora and fauna we currently depend upon, didn't exist.

    I'm not sure that we could tolerate the atmospheric conditions of that era either.

    Isn't it only going towards Mars for part of its year?

    That’s mild.
    We have had periods of time in which ice almost completely covered the earth.
    At other times we had tropical Flora growing in the arctic circle.

    Most people with even cursory exposure to what we know of prehistoric earth are not surprised by these changes.
    It is fascinating. However these changes in the past happened over centuries, or even millennia.
    Having it happen over a few decades is rather concerning.

    The last rapid atmospheric CO2 increase lead to the largest extinction event in the planet's history, and it might have been at a slower rate than today.

    I haven't been under the ice in the last two decades, but my understanding is that there aren't very many palm trees there even today.
    I HAVE been to my beloved home state of Indiana in the last week and I noted the usual absence of glaciers or an inland sea.
    As far as the anthropogenic component of the CO2 and ocean acidification is concerned, even if it's as bad as the "experts" opine that it is......one only has to be older than three years to remember a very recent and VERY poignant example of how humans react to a global, human caused crisis.
    Frankly, at this point, doing nothing is looking more and more attractive..... ;)
