Antarctica 2.0 - 8

Fig. 1 2000 yrs of temperatures (red=hotter)
The graphic at Fig. 1 depicts the temperature trends since the birth of Jesus Christ.

The red colors at the end of the rainbow depict warming of the past few decades.

This warming is not due to changes in or on the Sun (The Conversation), no, the truth about it, according to Oil-Qaeda, is that their fossil fuel products are the source of the warming and the melting of the ice sheets (Humble Oil-Qaeda).

Those melting glaciers that Humble Oil-Qaeda bragged about are now positioned to destroy civilization as we know it.

A few examples in Dredd Blog posts focused on that approaching event (Why Sea Level Rise May Be The Greatest Threat To Civilization - 6Hot, Warm, & Cold Thermal Facts: Tidewater-Glaciers - 3, Antarctica 2.0 - 4, Antarctica's Glaciers by Ocean Area and WOD Zone, Mysterious Zones of Antarctica - 4 (ocean current circling Antarctica has more flowing water in it than all the land based rivers on Earth combined).

One of the "stars" of that series was Thwaites Glacier (a.k.a. "The Doomsday Glacier") located in the Amundsen/Bellingshausen Sea area of Antarctica.

The study of the nature of the seawater impacting that area was graphically depicted many times years ago on Dredd Blog.

A very recent study this year has confirmed the facts set forth in those Dredd Blog posts:
"A team of scientists has observed, for the first time, the presence of warm water at a vital point underneath a glacier in Antarctica--an alarming discovery that points to the cause behind the gradual melting of this ice shelf while also raising concerns about sea-level rise around the globe.

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," explains David Holland, director of New York University's Environmental Fluid Dynamics Laboratory and NYU Abu Dhabi's Center for Global Sea Level Change, which conducted the research. "If these waters are causing glacier melt in Antarctica, resulting changes in sea level would be felt in more inhabited parts of the world.

The recorded warm waters--more than two degrees above freezing--flow beneath the Thwaites Glacier, which is part of the Western Antarctic Ice Sheet. The discovery was made at the glacier's grounding zone--the place at which the ice transitions between resting fully on bedrock and floating on the ocean as an ice shelf and which is key to the overall rate of retreat of a glacier."
(Antarctica Thwaites, emphasis added). (cf. ITGC Thwaites).

In the next few weeks and months I will revisit all of that and more using data thru 2019.

This data will show the trend, not the politics of this matter, in terms of the seawater temperatures at Thwaites Glacier and other locations around Antarctica.

Specifically, I will focus on seawater temperatures that will cause tidewater glacier ice to melt (hint ... it is colder than the temperature they measured by a degree or so).

The current republican led senate denies and is allergic to facts (US Senate officially votes to ban witnesses from Trump’s impeachment trial).

They will eventually do the same (ban facts) with testimony as to the reality of global warming induced climate change (if their fascist tendencies continue).

The trend of what is happening under the sea around Antarctica is utterly immune from the political trances of the U.S. and Australian governments:
"This is not a political game where pols flip flop and change their minds about as much as they lie through their teeth to our faces.

They can go from worse to better, or from better to worse on a daily basis.

On the other hand, the climate change predicament is real and it will not get better in our life times, or in the lifetimes of our immediate descendants."
(Antarctica 2.0). Stay tuned.
