Huge Cavity Melted Out in Antarctic Glacier: Part 1 of 2 // Feb 4, 2019

A huge cavity–4 km wide by 10 km long by 300 meters high–has melted at the glacier base in only 3-5 years.  Total melt of west Antarctic glaciers:

  • Would raise global sea levels about 5 meters;
  • Greenland glacier melt would add 7 meters;
  • East Antarctic plus mountain glacier melt would add 60 meters (total about 72 meters = 238 feet).

I discuss how melt rates of Antarctica glaciers are rapidly increasing due to warm salty ocean water incursions under the ice; in fact under Thwaites Glacier in west Antarctica an enormous hole— 4 km w x 10 km L x 300 meter H–has appeared in only a few years.

Ref:  Huge cavity in Antarctic glacier signals rapid decayA gigantic cavity – two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall – growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier. The findings highlight the need for detailed observations of Antarctic glaciers’ undersides in calculating how fast global sea levels will rise in response to climate change.

Researchers expected to find some gaps between ice and bedrock at Thwaites’ bottom where ocean water could flow in and melt the glacier from below. The size and explosive growth rate of the newfound hole, however, surprised them. It’s big enough to have contained 14 billion tons of ice, and most of that ice melted over the last three years’.

    To frame the scale of what needs to happen in order to enable Earth to regain stability of heat transfer so mild range of climate habitat remains viable into future; It involves stopping truth melt.
    The world of Big Media and pecuniary fiduciary duty filters out the voices of scientists and laymen alike who try and frame the picture differently. Specifically involving the need to pull rug out from under the Midas Touch Madness that makes for good TV and politics but leaves Earth Isolated.. There is a cavity growing in the Glacial Flow of Time-Stress where Truth touches Bedrock ~Sea.
    The Sea of Life is calving great chunks of long time Open Systems of Nature ~ Lie Level Rising.
    You can see the level of this great trump threatening the ability to create work to stop Extinction.
    You can see if you look references to Science and history of Earth Simply in light of Geologic T…
    Geologic Time relative to Life on Earth since Oxygen Two Exploded upward is about 1/2 Billion,,
    Time man has been around creating over-indulgence of technology ~ End Cambrian Explosion.
    There is a great cavity of eternal regret I believe growing in the flow of energy in the Universe..
    We can choose to close our eyes to Danger Unacceptable or aim high and try and change end.
