    I do hope that you are correct.....
    but I suspect that deliberately turning deserts green and diverting water into deserts could play a significant role in
    keeping ocean levels stable.

    Giant crack frees a massive iceberg in Antarctica

    Icebergs formed from sea ice do not affect sea level. They are already displacing water.

    True... but the ice that melts and / or cracks and slides off the land based Greenland Ice Pack is very different. This can also be said for a significant percentage of the West Antarctic Ice Sheet.

    You're talking about glacier ice in Greenland; more than compensated by new snowfall. In Antarctica almost all the West Antarctic sheet is sea ice.

    True.. but the major points are still valid.

    The major point is that a high percentage of the ice on the West Antarctic Ice Sheet is vulnerable to rapid cracking and sliding for a number of reasons.

    In a way... the WAIS is as vulnerable as the ice on the land based Greenland Ice Pack.

    False Alarm: IPCC Models Say A Warming Antarctica REDUCES Sea Levels -0.8 Of A Meter By 3000
    By Kenneth Richard on 15. March 2021

    Share this...
    The IPCC-endorsed anthropogenic global warming (AGW) paradigm finds a warming Antarctica results in more precipitation locked up as ice on the continent. This contributes to reducing sea levels: a -1.2 mm/year−1 mitigation of sea level rise over the next 80 years.
    In the 4th IPCC report, Working Group 1 (the physical science) reported that as global temperatures rise, “GCMs [models] indicate increasingly positive SMB for the Antarctic Ice Sheet as a whole because of greater accumulation.” This means that by 2100 Antarctica “would contribute 0.4 to 2.0 mm yr−1 of sea level fall.” Over the next 980 years, Antarctica’s ice accumulation will reduce sea levels by nearly a full meter (-0.8 m by 3000).

    The position that Antarctica will significantly reduce sea levels over the next century due to rising anthropogenic greenhouse gas emissions has been endorsed elsewhere in the scientific literature (Krinner et al., 2007, Palerme et al., 2017). . . .

    Antarctic ‘Catastrophic Ice Sheet Collapse’ Alarmism Gets Axed In 2 New Scientific Papers
    By Kenneth Richard on 23. July 2018

    Share this...
    Newly published science reveals scientists grossly underestimated the timescales for land uplift in compensating for Western Antarctica ice mass loss, leading them to conclude “the ice sheet may stabilize against catastrophic collapse” (Barletta et al., 2018). Furthermore, even if the most vulnerable ice shelves in the Antarctic Peninsula did collapse completely, the total ice melt contribution to sea level would be negligible – less than 1 centimeter by 2100 (Schannwell et al., 2018).
    In recent decades, Antarctic climate trends have not been favoring alarmist perspectives predicated on the assumption that anthropogenic CO2 emissions are catastrophically melting glaciers and contributing heavily to sea level rise. . . .

    @Jack Hays

    Think of not only Antarctica and the circumAntarctic Current
    but North Polar and :flagcanada: ice melt

    All that fresh water draining into the
    Oceanic Thermal Conveyor Currents,
    simultaneously at polar regions.
    Think, "Day After Tomorrow" science

    Our Earth's thermostat! :worship:
    Too Hot, melt polar regions (above paragraph)
    Too Cold, make polar ice & glaciers too.


    The Medieval Climate Optimum becoming
    The Little Age in so few years.

    AboveAlpha did a rather brilliant job of describing how that could well work out.

    He thought that we were doomed.... but I still have hope for a miraculous shift that will set in motion a truly utopian world as predicted by Isaiah, Jeremiah, Ezekiel and the minor prophets.

    This verifies why more ice is being added to Antarctica than is melting off the ice there.

    This helps to explain why we have not have serious rise in ocean levels so far.

    Why Is Antarctica’s Sea Ice Growing While the Arctic Melts? Scientists Have an Answer
    Global warming is melting the Arctic and glaciers worldwide, but not so much the sea ice in Antarctica. Observational data offers clues climate models did not.

    Lots of melting going on on the land based Greenland ice sheet this summer....
    melting of ice in the Arctic is totally different because it is ice floating in water and does not affect ocean levels.

    Yeppers,
    He smite the wooly mammoth and the glaciers, created the Great Lakes, and brought forth Yoopers and beer!

    The Earth constantly changes. If it didn’t, humans would not have experienced the stress necessary to adapt and overcome diversity.

    And if the Earth tips over, I help I am here to see it!

    Actually.... I do believe in a Supreme Creator but.... I believe that the Most Ancient Intelligence has put us humans largely in control of our own destiny to such an extent that our decisions can actually alter the space time continuum and set in motion different time lines.

    In alternate time line Mr. Gore wins the 2000 election but negates Global Dimming....



    There is a real possibility that the significant decrease in the Global Dimming Effect caused by shutting down the world economy over the past year and a half may have played a significant role in the heat wave experienced in western Canada and the USA over these past months.

    The heat wave in western USA and Canada, Global Warming or negation of Global Dimming Effect?
