Crater under Greenland points to climate-altering impact in the time of humans

Looks like the maverick geologist Randall Carlson was right. The evidence was pretty damn good, but many in the mainstream geology had a hard time accepting it for some dumb reason. Just goes to show that real scientists should never bow to consensus opinions. The outliers always advance the fields.<p>Go listen to Randall&#x27;s Joe Rogan appearances, they will blow your mind:<p><a href="https:&#x2F;&#x2F;youtu.be&#x2F;R31SXuFeX0A" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;R31SXuFeX0A</a><p><a href="https:&#x2F;&#x2F;youtu.be&#x2F;G0Cp7DrvNLQ" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;G0Cp7DrvNLQ</a><p><a href="https:&#x2F;&#x2F;youtu.be&#x2F;0H5LCLljJho" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;0H5LCLljJho</a><p><a href="https:&#x2F;&#x2F;youtu.be&#x2F;tFlAFo78xoQ" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;tFlAFo78xoQ</a><p>The Younger Dryas Impact Hypothesis:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Younger_Dryas_impact_hypothesis" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Younger_Dryas_impact_hypothesi...</a><p>The controversy:<p><a href="https:&#x2F;&#x2F;www.sciencenews.org&#x2F;article&#x2F;younger-dryas-comet-impact-cold-snap" rel="nofollow">https:&#x2F;&#x2F;www.sciencenews.org&#x2F;article&#x2F;younger-dryas-comet-impa...</a>

Pablo Rodas-Martini on the significance of those findings:<p>&quot;Wow! This scientific finding is huge. It rewrites the Younger Dryas: it explains the melting of ice sheets, the pouring of meltwater into the Atlantic, the disruption of the ocean conveyor belt, and the colder temperatures in the Northern Hemisphere.&quot;<p>[1] <a href="https:&#x2F;&#x2F;twitter.com&#x2F;pablorodas&#x2F;status&#x2F;1062795179139194880" rel="nofollow">https:&#x2F;&#x2F;twitter.com&#x2F;pablorodas&#x2F;status&#x2F;1062795179139194880</a>

If you are interested in facts, it is always better to read the scientific article (&quot;A large impact crater beneath Hiawatha Glacier in northwest Greenland&quot;), if you can[1][2].<p>I stopped reading this summary at &quot;and the released steam, a greenhouse gas, could have locally warmed Greenland, melting even more ice.&quot; Yes, steam is a greenhouse gas. No, that is not why Greenland may have been warmed by the steam. The steam itself is hot and would melt more ice. I can&#x27;t find the word &quot;steam&quot; mentioned in the science paper. Gell-Mann amnesia effect I suppose.<p>[1]<a href="http:&#x2F;&#x2F;advances.sciencemag.org&#x2F;content&#x2F;4&#x2F;11&#x2F;eaar8173" rel="nofollow">http:&#x2F;&#x2F;advances.sciencemag.org&#x2F;content&#x2F;4&#x2F;11&#x2F;eaar8173</a><p>[2]<a href="http:&#x2F;&#x2F;advances.sciencemag.org&#x2F;content&#x2F;advances&#x2F;4&#x2F;11&#x2F;eaar8173.full.pdf" rel="nofollow">http:&#x2F;&#x2F;advances.sciencemag.org&#x2F;content&#x2F;advances&#x2F;4&#x2F;11&#x2F;eaar817...</a>

&gt; The resulting explosion packed the energy of 700 1-megaton nuclear bombs<p>While not strictly on-topic, this wording is just weird, what&#x27;s wrong with simply &quot;700-megaton&quot;?

&gt; &quot;Though not as cataclysmic as the dinosaur-killing Chicxulub impact, which carved out a 200-kilometer-wide crater in Mexico about 66 million years ago&quot;<p>To clarify, this theory is has been called into question. I believe there have been previous HN discussions.

&gt; I can&#x27;t imagine how something like this impact in this location could have caused massive fires in North America<p>I&#x27;m no scientist but my initial thought would be that the asteroid prior to impact could have broken up during entry and scattered debris across North America.

I know this is going into conspiracy realm but do you think this could have caused mass wipe out of both humans and wildlife and that it could have possibly killed earlier advanced (agricultural and can build rather than hunter gatherer) civilisations.

&quot;Massive crater under Greenlands ice points to climate-altering impact of humans&quot; is the current title which is blatantly misleading.

Weird, I posted this yesterday, same article, same url, but it doesn&#x27;t show up under the past link.

Why was this renamed from the original title, erasing &quot;in the time of&quot;? This is highly misleading.<p>This is the actual title of the article: &quot;Massive crater under Greenland’s ice points to climate-altering impact <i>in the time of</i> humans&quot;
