The Canterbury Swarm and the Taurids

John Michael Godier: An exploration of the concept of the Canterbury meteor swarm and its links to the annual Taurid meteor shower and how these sometimes produce very large impacts on the moon and earth.

    Remembering also the excellent discussion we had here on the Talkshop back in 2011 concerning the possibility the Taurids may have caused the Younger Dryas Cooling.
    Well worth revisiting.

    Flitting around on the links this one from yr 2007 looked interesting. Because the dates today are established markers. Link:

    But the YD cooling, and the abrupt change, is no different from previous cycles; see

    A very good read was posted here but the figures are no longer there (but they are here )

    But more fundamental is the saw-tooth shape of the last 400k yrs. That is a sign of a process. What drives that process, and the various forcings that control the somewhat changing period between abrupt major triggers at saw-tooth bottom- which the R Hannon link shows so well-, is still very much unknown.

    R Hannon pin-points the 8k2 event. The first link above shows the dates of other events in the Holocene.

    This study prefers the solar activity explanation.

    4. Conclusion

    The radiocarbon production rate and the heliospheric modulation potential were reconstructed during
    the time interval 12000-8500BC. The reconstruction took into account the climatic variations. The
    periods of extremely high radiocarbon production rate are located. These periods are 11765 (11780),
    11100 (11120), 10700, 10425 (10420), 9245, 9150 BC. The periods of very high solar activity are
    10940, 10200, 9565 BC. It is possible also that the time intervals close to 9700, 9200-9000 BC were
    the periods of grand minima of solar activity.

    The NASA link takes me to YouTube…

    So does the Arvix link…

    Thanks EM, that’ll teach me to check links when copy/pasting from YT.
    Arxiv link should be
    NASA link should be
