Recent Discussion of Younger Dryas impact Hypothesis 20NOV2024

 Recent Discussion of Younger Dryas impact Hypothesis

Hi,

Unsurprisingly, Sweatman, Powell, and West have replied to Holliday et
al. (2023)’s refutation of the YDIH with Sweatman et al. (2024). In response,
Holliday and associates replied with Holliday et al. (2024) and an open access
supplementary material, YDIH Skeptics (2024).

The publications are:

Holliday, V.T., Daulton, T.L., Bartlein, P.J., Boslough, M.B., Breslawski, R.P.,
Fisher, A.E., Jorgeson, I.A., Scott, A.C., Koeberl, C., Marlon, J.R. and
Severinghaus, J., 2023. Comprehensive refutation of the Younger Dryas

Kamil Crater, Egypt, "Strip-mined" and Destroyed by Meteorite Criminals 13OCT2024

Kamil Crater, Egypt, "Strip-mined" and Destroyed by Meteorite Criminals 13OCT2024
by Paul V. Heinrich

Kamil Impact Crater 2023 showing destruction and in 2020.
Imagery © 2024 Google Earth / CNES/ Airbus
Click on image to enlarge.

I was looking at Wikipedia at the write up about the Kamil Crater at 22° 1'5.89"N latitude and 26° 5'15.69"E longitude. A recent addition to the Wikipedia article by Enrique Díaz-Martínez, Spain at https://en.wikipedia.org/wiki/Kamil_Crater
states:
"According to evidence provided by Google Earth images, Kamil crater morphology and its prototypical rayed structure (well-preserved radiating features) have been destroyed between 2020 and 2023, most probably due to exhaustive plundering of meteorite fragments. The last image of the well preserved crater is of February 2020, whereas it is fully destroyed in the next image dated May 2023, so it was destroyed between those two dates. The size of the wheel tracks visible on trails to/from the former crater indicate that heavy machinery was used for the collection of meteoritic material.”

The Wikipedia update note was added on October 10, 2024 by Enrique Díaz-Martínez, Spain.
https://en.wikipedia.org/w/index.php?title=Kamil_Crater&diff=prev&oldid=1250464561

https://en.wikipedia.org/wiki/Special:Contributions/Ediazmartinez

I looked at the Google Earth images and essentially agree with what is written. Although the exact timeline is open to interpretation, the aerial images do show that this crater, which is a protected site, has been destroyed by people illegally mining it presumably for iron meteorite fragments and spherules. Heavy machinery, presumably electromagnets, and other methods were used to vandalize, desecrate, and otherwise destroy this irreplaceable part of the Egypt's geological heritage for personal gain.

Undoubtedly, these stolen Egyptian meteorites are already in the marketplace for sale somewhere.

Fireball Movie Question- Korea Expedition for Antarctic Meteorites, KOREAMET 08OCT2024

Fireball Movie Question- Korea Expedition for Antarctic Meteorites, KOREAMET  08OCT2024

In [meteorite-list] Fireball Movie Question on Tue, 01 Oct. 2024, Rhett Bourland asked:

>My question is, does anyone know what meteorite they found?

I was not able to determine an answer to this question. A more detailed examination of the below papers might help.

>If you don't know, can someone point me towards some information about the material found by the South Korean team over the years?

Customs and Border Protection Crackdowns on some De Minimis Shipments into the US 02JUN2024

Customs and Border Protection Crackdowns on some De Minimis Shipments into the US

Currently, US Customs and Border Protection is cracking
down on de minimis Shipments from China into the US.
It is now currently limited to air shipments from China.
However, this crackdown could extend eventually to other
countries and ultimately to some degree to marine shipments.
  Because de minimis shipping consists of any goods that
is less than 800 dollars, this crackdown, might eventually
greatly delay the shipping of any package of goods and
lengthen the time it would to ship anything into the
United States. Also, any package of de minimis goods
shipped into the United States will be more closely scrutinized
by the CPB in terms of whether it is properly declared in
description and price by the sender.

  Although it is nothing to worry about now, the situation
could change in the future.


Below are some new articles-
