Huge 30-kilometre wide meteorite crater found under Greenland glacier


quote:

A giant meteorite crater has been found lurking beneath the Greenland ice sheet – and the impact might explain a puzzling mini ice age about 13,000 years ago called the Younger Dryas.

The crater – a round bowl-shaped depression about 30 kilometres wide – was discovered from old NASA radar data. It would have been made by a meteorite about 1 kilometre in diameter – a tenth the size of the asteroid that killed off the dinosaurs 66 million years ago.

Although the crater is completely covered by a region of ice called the Hiawatha Glacier, a subsurface river draining from underneath is leaving tell-tale sediment on the exposed land between the ice and the sea


quote:

Without access to the crater, the team haven’t yet been able to date the event more precisely than some time in the past three million years. But that leaves open the possibility the meteorite could be connected to the Younger Dryas, says McDonald.

The cause of this short episode of Northern Hemisphere cooling that started abruptly during a longer period of warming has long been unclear. There are several theories, including an impact from space, but there was no suitable crater recent enough.

If the Greenland meteorite had hit ice several hundred metres thick, as it is over Greenland now, it would have melted millions of tonnes of fresh water, which would have entered the sea. This could have disrupted ocean circulatory currents, and cooled the climate, McDonald speculates. “Circumstantially, the fact that we have found a crater hidden under ice opens up this possibility.”


Great Flood anyone???




We were literally reset (by a stone...)

In Greek mythology Sisyphus or Sisyphos (/'s?s?f?s/; Greek: S?s?f??, Sísuphos) was the king of Ephyra (now known as Corinth). He was punished for his self-aggrandizing craftiness and deceitfulness by being forced to roll an immense boulder up a hill only for it to roll down when it nears the top, repeating this action for eternity.

Posting here (from prior thread) to provide background for above:

Keep in mind that the guy below has been accused of being a "climate change denier" by the true believers


That statement / position alone is pretty telling about the motivations of the current political movement (gradualists, uniformitarians...). There is no search for knowledge or truth from these folks. Some folks just want to be "right" to drive policy/funding/agendas...

quote:

While this knowledge is, at present, within the purview of a small but growing number of catastrophist geologists, astronomers, and other scientists, it has fallen completely by the wayside in the public discourse. For the present time politics dominates the discussion of global change, and there is a powerful political incentive to direct the discussion towards anthropogenic forcing to the exclusion of natural forces of change, for human behavior is subject to political control and natural forces of global change are not


Randall proposes cataclysmic cosmic impacts as the source of radical changes to the earth and part of cyclical process that is downplayed by mainstream science

An open letter to a critic on the matter of chevrons, megatsunamis and bolide impacts.
by Randall Carlson



quote:

I am addressing this response to one issue raised regarding remarks about possible mega-tsunami deposits that I brought up during the podcast. It is my impression after investing a fair amount of time researching this phenomenon that it warrants serious consideration, especially in light of what we have witnessed during the past decade, two tsunami induced mega-disasters in Japan and the Indian Ocean. Several comments were particularly dismissive, so I am setting down this small exposition, without malice, to demonstrate that the remarks made on The Joe Rogan Experience were preceded by a substantial amount of background research and thought. While the following remarks pertain to this one issue specifically, they are also relevant to the general attitude evinced in many of the other comments critical of something I said that are obviously being made by individuals whose preconceived opinions were incompatible with the information I presented and their objections were nothing more than a knee jerk emotional response rather than a reasoned critique with some actual thought behind it.





Chevron forms created on a stream sandbar by local spring floods in Georgia, USA. The significant point is that these forms were produced by flowing water, not wind. After the flood subsides and the sand deposits dry out they will become subject to wind erosion and modification until they are stabilized by vegetation.




Chevron forms found on the southern tip of Madagascar. Were these formations created by wind or water? If the chevrons are formed of fine-grained wind transported sediment why is the line of demarcation at the distal end so distinct? What kind of aeolian process would produce features of this form and magnitude? The light colored deposits near the upper end of the chevrons are sand. This sand is undoubtedly being modified by wind, but this does not mean that the whole complex of lancet-like forms composing the chevrons were originally created by wind.

For scale...







The Burckle Crater impact is speculated to be Noah's flood...

Small scale parabolic dune forms and hummocky topography produced by local flooding in Peachtree Creek, GA are clearly visible in this photograph. The open end of the parabola seen in the top center points in the up-current direction which was from right to left. Again, these sedimentary forms are initially produced by flowing water and later modified by wind.



Large scale parabolic dune forms on the Rolling Palouse landscape of SE Washington State. Note the large parabolic shaped dune in the foreground. It opens upcurrent, flow was from right to left (north to south). Compare the general morphology of this landscape with the water shaped forms in the previous photograph. This landscape is the product of wind AND water. A study of mega-scale paleohydrology reveals the scale-invariant, or self-similar nature of fluvial forms across a wide variety of spatial scales and signifies its value as a means of comparison and recognition of mega features whose origins it is not possible to witness directly.









Summary:

-comet impact on North American icecap, images above (cooling was the existing paradigm prior to this)
-massive, cataclysmic flooding (see Washington state photo above)
-sea levels rise, massive amount of water vapor injected into the atmophere leading to a greenhouse effect/ rapid warming

Multiple impacts of varying scale have occurred leading to cyclical change....

Randall does a better job of describing this (in great, well referenced length) than I am above in this overview. His site and vids are definitely worth looking into.

You should. This process is felt to be cyclical...

Greenland ice sheet hides huge 'impact crater'
By Jonathan Amos BBC Science Correspondent 6 hours ago


quote:

What looks to be a large impact crater has been identified beneath the Greenland ice sheet. The 31km-wide depression came to light when scientists examined radar images of the island's bedrock.

Investigations suggest the feature was probably dug out by a 1.5km-wide iron asteroid sometime between about 12,000 and three million years ago.

My main takeaway, the Earth has been hostile to human development for most of time. It is basically a miracle
that we have seen such a calm period on Earth and in the nearby areas of the Milky Way Galaxy. This period probably won't last much longer.

May thine own ani be prepared

What does this mean for us? From what I remember from the podcast he was basically saying these impacts are much more common than we think

NASA finds possible second impact crater under Greenland ice
February 11, 2019 by Maria-José Viñas, NASA's Goddard Space Flight Center


quote:

A NASA glaciologist has discovered a possible second impact crater buried under more than a mile of ice in northwest Greenland.


quote:

If the second crater, which has a width of over 22 miles, is ultimately confirmed as the result of a meteorite impact, it will be the 22nd largest impact crater found on Earth.


FWIW: I have refined my view of this in the grand setting of the Electric Universe cosmological model. Bollides would have been produced during the chaos of this event (likely from Mars)

CRATERS | By Becky Ferreira | Feb 11 2019, 9:26pm
NASA Discovers Second Crater Hidden Under Greenland's Ice Within a matter of months,

NASA has discovered the first subglacial craters known to science. They’re both huge and relatively young.


quote:

NASA has detected a massive, ancient crater buried under two kilometers of ice in northwest Greenland. Even more surprisingly, it’s the second crater discovered under the region’s thick ice in recent months.

Stretching across 36.5 kilometers (22 miles), the crater was likely formed by an asteroid impact within the past 2.6 million years, according to a study published Monday in Geophysical Research Letters. If the feature is confirmed to be the fallout out of an asteroid strike, it will rank as the 22nd biggest impact crater known on Earth.


The other data argues against this, but it is worth noting:

quote:

Given their proximity to each other, MacGregor and his colleagues pondered whether these craters may have been formed by the same impact event. Perhaps a binary asteroid system struck Earth, or one asteroid broke up into two pieces during atmospheric entry.


quote:

The possibility of additional subglacial craters beneath the Greenland and Antarctic ice sheets should be investigated, as our discovery further emphasizes the ability of ice sheets to both bury and preserve evidence of terrestrial impacts,” the team said.


Many mysteries under the ice...

Why isn't this, which is completely devoid of politics, on the OT?
