The Younger Dryas impact hypothesis has received considerable attention since its publication in 2007 in the prestigious peer-reviewed journal PNAS (Proceedings of the National Academy of Sciences). It suggests the Younger Dryas geological period and mini Ice-Age, from around 10,850 to 9600 BC, along with associated megafaunal extinctions and human societal changes, was triggered by a catastrophic cosmic impact, probably with a fragmented comet from the Taurid meteor stream.

As of now, this paper by Richard Firestone, Allen West and Simon Warwick-Smith and colleagues has amassed over 550 citations in Google Scholar - which is a lot! It is on its way to becoming a classic. But it has also received more than its fair share of criticism, mostly sustained from just a handful of vehement opponents. But has any of their criticism stuck? And what is the status of Firestone et al.'s paper today? Has the dust settled on an outcome? Are we there yet?

NASA knows that the celestial impact threat is real and that it is comets, not asteroids. So NASA is launching the DART mission to deflect the comet. NASA is pretending their target is the moon of an asteroid (Didymos), but they are really practicing against a theoretical comet. NASA is really preparing to strike a real comet (one of Vulcan's B Comet Swarm) that will threaten Earth in September-November 2021, 2022 or 2023 (OR 2024). Early October 2022 is the most likely time of first arrival of the real threat. Earth has already been hit by fragments from the leading edge of the B Comet Swarm that struck NH and CA during early October 2017 and caused massive wild fires.

NASA CHIEF WARNS ASTEROID THREAT IS REAL: 'IT’S NOT ABOUT MOVIES - May 1, 2019

Asteroids could very well hit Earth in the near future and cause widespread destruction, according to NASA.

NASA's administrator emphasized the significance of planetary defense in protecting people against possible asteroid and comet impacts during his introductory speech at the 2019 Planetary Defense Conference on April 29.

THE B COMET SWARM CLUSTER CL-1a: 2018 - 2020

"Several diverse sources have suggested that a catastrophic celestial impact events may occur in Earth's near future. :Comet C/2017 K2's perihelion is associated with this event, but it is not the cause. Analysis suggesting that minor cosmic events have already occurred during calendar year 2017. This web page shows cosmic events relating to a possible swarm of incoming comet fragments, some of which have already impacted Earth. Future impact events may well occur that could cause blast, tsunamis', and a major weather change resulting in a new 'Younger Dryas like' Ice Age. Impacts in the Atlantic ocean, Caribbean and Mediterranean sea are anticipated. Major Threat times are Sep. - Nov. of 2021, 2022 & 2023. 2022 and 2023(24?) contains dual peak threat times (Cl-1ai & Cl- 1aii ). Based on the Bible Code, bodies from Swarm B:Cl-1 (Swarm B Cluster 1) are anticipated to impact during Hebrew Year 5781 (starting 9/19/2020) and/or 5785 (starting 10/03/2024). This suggests threat dates of Sep. - Nov. of 2020 and 2024. At least one significant impact event may occur as early as Sep. - Nov. of 2020. Examination of the 2017 fireball activity indicates two dangerous parts of Earth's orbit, Oct 4 - 23 and November 10 -16. Surprisingly, this cosmic impact threat is being reported by Israeli NEWS Live and supported by Pastor Coverstone's dreams (Dreams 3,6 and 7). There is a modest possibility that Pastor Coverstone's Dream 3 is associated with Kato Mivule's vision of 'Wormwood' streaking over Arrowhead stadium on either 4, or more likely, 11 October 2020 heading for an Atlantic impact. The meteorite 'Warmwood' will follow in November 2020 (10 - 16 Nov?) impacting the southwest USA near the Gulf coast. Efrain Rodriguez's giant meteorite could strike in the third week of November, 2021 or the second week of November in 2022 with the latter date favored. Additional impacts are anticipated in the following four years."
