Alaska’s 2025 mega tsunami

[John Nissen]

Dear Peter,

This highlights one of the major risks from Arctic warming: megatsunamis to hit coastal communities around the North Atlantic coast, especially in estuaries that would funnel the pressure wave, such as the Bristol Channel.

Curiously the Bahamian are.at particularly high risk because any collapse of megaton or gigaton slabs of ice into the sea to the west of Greenland would produce a pressure wave half reflected by the North Atlantic Ridge, which runs north/south for 400km or so. There is evidence of this happening at the end of the Eemian and beginning of the Holocene, when huge boulders were thrown high up onto the northeast facing side of the island of Eleuthera.

Add to this the danger from tipping point catastrophes for climate and sea level rise.

We must put together an international call for extremely urgent action to refreeze the Arctic and start the process of nudging the planet back towards Holocene norms.

Best wishes, John

Dear Restorers,

The paper points out that this catastrophe happened at the edge of a retreating glacier.  I find that to be a key takeaway.  

A previous film showed an ice sheet shaking itself apart in a span of one hour.  Short-term, each tiny quake contributed to the instability of the entire front of the ice sheet.  This instability continued for an hour.    This mountain collapse was preceded by thousands of tiny earthquakes. 

Long-term, the melting edge of any ice sheet removes how many thousands or millions of tons of ice overburden from that one place on earth.  The earth's crust responds by rebounding upward at that one spot.  The stress on that one spot of the earth's crust builds until it lets loose in small earthquakes, then the big quake.  

We have been warned that what we now call the Antarctic continent is often kilometers of ice sitting on the sea floor.  If Pluto isn't a planet then is Antarctica really a continent?  

A group of researchers theorized that if Antarctic ice disappears, the West Antarctic bay, known as the WAIS by a previous generation, can become largely ice-free.  This has happened several times before in geologic history, the researchers point out.  

The disaster movie will be about that big Antarctic quake.  What would New York City suddenly resemble?

This sounds hopeless but I have cheap solutions for restoring the front of an ice sheet.  We need to grow new ice all the way down to the bottom of Pine Island Bay.    It uses drones, pipes and tiny wind turbines.  See:  https://klinkmansolar.com/kfrozen.htm#R4 for a sketch.

Yours in Hope,
