   These extinctions may have been caused, at least in part, by the direct effects of a cosmic impact, including both the shock wave and the heat, and subsequent major and cascading ecological changes, such as regional wildfires, climate change, vegetation disturbance and shifts. The apparent suddenness of the event that occurred at the onset of the YD requires investigation of very high chronological resolution to test the hypothesis. Sedimentary records from the Northern Channel Islands and the Santa Barbara Basin, and I'll pull up a map in a second, um that were extracted uh that are um studie…

   So, in other words, you've got these pine, juniper, and cypress forests growing on the California mainland and on the the island, which which during at this point is a single island, right? It's In In when I pull up the map here in a second, you'll see. Um Right? Um the onset of the Younger Dryas closely correlates with a major abrupt decline in the abundance of juniper cypress pollen, suggesting that these trees were abundant regionally before, but not after 13 to 12.9 ka. The major reduction in the mountain forest vegetation corresponded with a distinct increase in grass and herbs, mainly fr…

   Fire is a recurring ecological disturbance in tropical grassy biomes, exerting strong selective pressure. Although adult species have a high capacity for resprouting, little is known about the age at which young plants acquire resilience to fire. This knowledge has practical implications when considering fire management frequency and the introduction of prescribed burns in areas under restoration to ensure the survival of vegetation. Thus, our objective was to evaluate the time required for native Cerrado grasses to become resilient to fire, analyzing their survival and recovery capacities at …

   And again, that is going to be consistent with uh habitat loss because the larger the animal, the more food that's required, uh the more gestation time that's required, the more time to nurture the young uh to viability before they can survive on our own, uh and so on. So, when you destroy habitat, every one of those factors gets affected. Um so let's go on with this because he makes some interesting uh conjectures here. Most of the plausible cases or causes for late place to scene extinctions were under discussion in the first half of the 19th century. Currently there are only two serious con…

   This influx of fresh water, less dense than the salty ocean water beneath it, may have disrupted the Atlantic meridional overturning circulation, the deep ocean conveyor belt that carries warm tropical water northward and moderates the climate of Europe and eastern North America. Shut that system down and the north freezes. The model is well supported by Oenographic data and climate simulations and many scientists consider it sufficient to explain the younger dryers without invoking anything more dramatic. But in 2007, a multid-disciplinary team of researchers proposed an additional or alterna…

   In this paper, we provide evidence for an extraterrestrial or ET impact event at 12.9Ka, which we hypothesized caused abrupt environmental changes that contributed to YD cooling, major ecological reorganization, broadscale extinctions, and rapid human behavioral shifts at the end of the Clovis period. So, this is the paper that launched the I think one of the more preeminent scientific controversies of our time um and of course it was immediately savaged by the critics u before I think long before they had a chance to even fairly evaluate the merits of the hypothesis. So we have another paper …

    Both of which are key um uh um key sites that provide insight into understanding the Younger Dryas. Um So, obviously, both of those sites are going to be worth uh further discussion because the lessons gleaned from either of those two sites has such direct relevance to understanding the Younger Dryas. Although much remains to be learned about this boundary layer, the co-occurrence of these exotic materials forms the basis of the Younger Dryas boundary cosmic impact hypothesis. Large cosmic impacts can have major effects on Earth systems and are known to trigger abrupt climate shifts, widesprea…
