Public wants NASA to Monitor Asteroids/objects that Could hit the Earth

Public wants NASA to Monitor Asteroids/objects that Could hit the Earth

NASA’s priorities appear to be out of whack with what the public wants
"The public thinks that we should have a space program that saves Earth."
https://arstechnica.com/science/2018/06/nasas-priorities-appear-to-be-out-of-whack-with-what-the-public-wants/

One of the highest public support for NASA priorities is:
"..."monitor asteroids/objects that could hit the Earth" (62 percent)."
Majority of Americans Believe It Is Essential That the U.S. Remain
a Global Leader in Space Despite the increasing role of private
companies in space exploration, most believe NASA’s role is still
vital for future, Pew Research Center, June 6, 2018

Aliens Are Real, But Humans Will Probably Kill Them All

Yet another paper about extraterrestrial intelligence and
the Fermi paradox. It is interesting to see that the lack of
solid evidence does not inhibit writing about a subject.

Drumlin Formation Not Necessarily Evidence Of Catastrophic Event

Drumlin Formation Not Necessarily Evidence Of Catastrophic Event

People have selectively used the ideas of Dr. John Shaw to claim that they are undisputed indicators of catastrophic subglacial floods associated with extraterrestrial impacts. However, in their arguments, they completely either ignore over overlook any other research that strongly indicate that there is a lack of
any connection between catastrophic subglacial floods and drumlin formation. Some of this recent research is:

Worst Misidentification Ever- FAKE! China's unique natural impact glass

Worst Misidentification Ever- FAKE China's unique natural impact glass

In " worst misidentification ever,"
Alfredo Petrov wrote on Tue, 23 Jan 2018,
This has got to be the worst, and funniest, in a schadenfreude sort of way, hoped-to-be-a-meteorite ever:

I am nominating for second or third worst misidentification of some obviously man-made glass as a Chinese impactite, the "Shui jing glass" featured in the below YouTube videos.

This material reminds me of the tables covered with varicolored glass blocks that I saw out in front of Arkansas rocks shops when I went fossil and rock collecting decades ago.

There is the below abstract:

A crackpot ejection theory about China's unique natural glass
Endocrine Abstracts (2015) 38 SE1.4 DOI:10.1530/endoabs.38.SE1.4
(Society for Endocrinology, British Endocrine Societies)
http://www.endocrine-abstracts.org/ea/0038/ea0038SE1.4.htm

"I shall present evidence from the carvings that points to a unique post-impact lateral ejection of molten glass; and that this was later carved by grinding using impact diamond sand."

Field Work Problem? - Rodents are Chewing up Car Wires

Field Work Problem? - Rodents are Chewing up Car Wires

This might seem off-topic, but it might apply to vehicles used in the field for meteorite hunting.

Why Rodents are Chewing up Car Wires and What You Can Do to Prevent it.
https://www.wheels.ca/news/rodent-damage/

Every farmer knows that vermin nesting in a warm engine bay is yesterday’s news. What is troubling is the growing volume of online stories about rodents chewing up expensive wiring looms that keep Audis, Hondas, Toyotas and Volvos running.

Sea-surface and Air Temperatures Started Cooling Before Start of Younger Dryas

Sea-surface and Air Temperatures Started Cooling Before Start of Younger Dryas

I assume that everyone has heard about the new "Journal of geology" papers as at Burn Paper
A new day at the Cosmic Tusk
https://cosmictusk.com/9483-2/

As far as the start of the Younger Dryas and the uncertainties of science are concerned, there is:

Levac, E., Sandercombe, S. and Chmura, G.L., 2018.
The Younger Dryas in palynological records from the northern Northwest Atlantic: Does the terrestrial record lag the marine and air records?.
Palaeogeography, Palaeoclimatology, Palaeoecology, 490, pp.269-279.
https://www.sciencedirect.com/science/article/pii/S0031018217307514

"Sea-surface and air temperatures started cooling 250 and 110 years before the start of the YD, hence there is a 140 years delay between ocean and atmosphere."

and

"Vegetation reversals in N. America do not represent the start of cool conditions."

How can an impact, no matter how powerful, have started cooling Earth centuries before it happened?

This and a lot of other fine-grained inconsistencies constantly give me heretical doubts about what should be a quite appealing and simple explanation of puzzling Quaternary events.

Other papers with similar details is:

Emery-Wetherell, M.M., McHorse, B.K. and Byrd Davis, E., 2017. Spatially explicit analysis sheds new light on the Pleistocene megafaunal extinction in North America. Paleobiology, 43(4), pp. 642-655.

Widga, C., Lengyel, S.N., Saunders, J., Hodgins, G., Walker, J.D. and Wanamaker, A.D., 2017. Late Pleistocene proboscidean population dynamics in the North American Midcontinent. Boreas, 46(4), pp. 772-782.
