    Ocean temperatures at the grounding line of Thwait's Glacier is measured.

    More details from the article:
    The researchers, working on the Thwaites Glacier, recorded water temperatures at the base of the ice of more than 2 degrees Celsius, or 3.6 degrees Fahrenheit, above the normal freezing point. Critically, the measurements were taken at the glacier’s grounding line, the area where it transitions from resting wholly on bedrock to spreading out on the sea as ice shelves.
    Studies have forecast its total collapse in a century and also in a few decades. The presence of warm water in the grounding line may support estimates at the faster range.
    That is significant because the Thwaites, along with the Pine Island Glacier and a number of smaller glaciers, acts as a brake on part of the much larger West Antarctic Ice Sheet. Together, the two bigger glaciers are currently holding back ice that, if melted, would raise the world’s oceans by more than a meter, or about four feet, over centuries, an amount that would put many coastal cities underwater.

    “Warm waters in this part of the world, as remote as they may seem, should serve as a warning to all of us about the potential dire changes to the planet brought about by climate change,” said David Holland, a lead researcher on the expedition and director of New York University’s Environmental Fluid Dynamics Laboratory.

    Warmest day in Antarctica...... followed by another warmest Antarctic day, today........:

    20.75degC = 69.35degF.
    In conjunction with the warmest global January ever, man-made global warming just keeps warming. Ah, yeah..... January 2020 made it the 421st consecutive month over, the 20th century average temperature. All this heat, despite the Total Solar Irradiation being low for the last 13 or 14 years.

    Further information:

    From the article:
    The planet's four warmest Januaries have occurred since 2016, and the 10 warmest Januaries have all occurred since 2002, NOAA said.
    Warmer temperatures mean melting snow and ice. The extent of Arctic sea ice was 5.3 percent below the average from 1981-2010, and Antarctic sea ice was 9.8 percent below the average.
    .....warmth itself is that it occurred without any assistance from an official El Niño event, Weather Underground meteorologist Robert Henson said. El Niño, a natural warming of Pacific Ocean water temperatures, also tends to produce warmer global temperatures.
    Looking ahead, NOAA scientists said that 2020 is also "very likely to rank among the five warmest years on record."

    Last month to be below the 20th century average was some time in 1985, I think. Its good to know that the Antarctic isn't melting...... NOT!

    An Antarctic iceberg the size of Seattle, just got lopped off the Pine Island Glacier:
    https://www.cbsnews.com/news/satell...an-seattle-break-away-from-antarctic-glacier/

    If we live long enough, we might see other icebergs busting off the Pine Island Glacier, as already has been seen.... & vast glacier Ice Sheet back-ups behind the Thwaites, speeding up.... as predicted.
    Of course, such predictions do NOT come from man-made global warming deniers.
