Sea Level Crisis Update

If sea level keeps falling, we will have to walk further to get to the beach.

    If indeed over 4000 years old, these stumps should be very helpful for climate research.
    The tree ring data should give some indication of climate conditions then.
    Iirc, there are tree ring chronologies back through the pre christian era, but not aware of them going back into the 2000-3000BC period.

      The scientists exhumed organic material and carried out radiocarbon dating on wood remains from buried dead trees at the upper tree limit, and from rock glaciers on trough slopes from six glacial valleys in the North Chuya Range, SE Altai. They compiled an extensive dataset, which form the basis for understanding the relative magnitudes and timing of the most important glacial and climatic events of SE Altai.

      Their conclusion:

      New data refute the traditional concept of the Russian Altai Holocene glaciations as a consecutive retreat of the late Würm glaciers and argue their complete degradation at the head of trough valleys at least 7000 cal. years BP.”

      Moreover, they identified three periods of glacial advances: from 4900 to 4200 cal. years BP (Akkem stage), from 2300 to 1700 cal. years BP (Historical stage) and in the 13th–19th centuries (Little Ice Age (LIA) or Aktru stage). The coincident extremes of lowering temperature and increasing precipitation during the Akkem stage led to abrupt glacier advances and forming of the most remote moraine complexes downstream in the valleys.

    I spend a couple of weeks each summer up by the coast in North Denmark. Widening beaches, and newly appeared beaches have become a feature of the last 10 years. No sign of sea levels rising there.

    Are we getting colder or warmer. I wish I could have some of that old wood. Jeff

    Those stumps have been regularly exposed in winter for quite some time, it was dry land ~9,000 years ago, research shows that it transitioned from forest to salt marsh between 6,500 and 3,000 years ago. It is believed to extend about 20 miles from the present shoreline. The area is neutral regarding isostatic rebound, to the north the land is rising and to the south it’s sinking.
    Welsh legend refers to the area as Cantre’r Gwaelod which had a capital called Caer Wyddno, said to have been flooded because the sluice keeper was drunk! Vestiges of ‘Caer Wyddno’ have been found about 7 miles off shore. It’s also mentioned in the Mabinogion that the waters between Wales and Ireland were once a narrow strait.
