Global Cooling 13,000 Years Ago Was Caused by Volcanic Eruptions, Not Meteors

Active Volcanoes

Analysis of sediment found in Hall’s Cave shows volcanic eruptions responsible for cooling of Earth around 13,000 years ago.

  1. More ignorance. The sun novas on a cyclical basis and it produces impactors and plasma that pummels the earth and causes earthquakes which cause volcanoes. This is not rocket science it a common sense. If all stars nova then ours does to. We have proof it hit the moon too that s wht we went there to look for impacotrs that were present on earth. We are due for another one very soon they happen every 12000 tears like clock work . what do you think the part cloud is. A blast cloud duh. From the last blast

  2. how is it possible that it has not apparently occurred to this person that perhaps a meteoric impact which caused the extremely rapid decimation of an ice sheet a mile thick & a continent in size with its accompanying weight might have been the catalyst to extreme seismic activity…
    Exacerbating the conditions brought on by the meteor.
    I and my sixth grade education for one think that’s worth considering and therefore mentioning.

    Good research; however, there is evidence of meteorite impact during that period time as well. To dismiss the meteorite impact evidence is an error. I strongly think that both contributed climate to climate Cooling.

  4. if it was volcanic there must be a fingerprint.

    To cool the planet by 3 degrees you are talking about a category 8 volcano. Which there is no evidence of any cat 8 eruptions since Toba.

    Not saying it didn’t happen but none of the ice core samples have indicated this.

  5. The Dryas diamond nano spherule layer covers the entire globe. One little cave in South Biblebeltia with volcanic isotopes is not enough to upend the only plausible explanation for an extinction level event. If an asteroid pierced the mantle with enough force, there would naturally also be some volcanic activity near the epicentre. Its probably just a lava tube caused by exactly that, not some “First Americans University” smoking gun put there to exonerate a tirade of preposterous nonsense the institute has been putting out since its inception.
