Weird how some massive impacts like Manicouagan can create relatively little disturbance whist only mid sized impacts like Eltanin can trigger such drastic changes. I guess it mostly depends on the positioning of the continents, we're in a rather interesting time in that regard. But I also wonder if the strength of the crust affects it at all, Eltanin struck relatively fresh oceanic crust whist Manicouagan is on the hard, cold, and ancient Canadian Shield. I'd imagine it would be a tad harder to pulverize that crust than the stuff Eltanin hit.

Interesting and informative. I, however, would be reluctant to assign the recent cycling of ice ages to this one event and feedback loops. There doesn't seem to be much evidence for glaciation after the impact 65 million years ago right after the CT boundary, while there is significant data showing consequential desertification. To me, the answer is up in the air: whether this meteor, or plate tectonics closing the Pacific/Atlantic Panama gap, or the rise of the Himalayas, scrubbing CO2 out of the atmosphere, or the change in deep ocean water formation at the Greenland/Iceland gap, or ??? Climate is tricky. Are we still in an ice age, or fully recovered? Has sea level risen an average of 24" a century for the last 12,000 years? What was the glacier population worldwide at 1000 AD when Greenland was colonized? More questions than answers. Thank you for the new data set.

The salt water would have killed off many ground grasses, trees, and land animals before the darkness and cold came wiping away most species existing then. Then there is the Earth 's Precession every 25,700 years. If it hit at the wrong time during it's Milankovitch cycle it would have been a much longer ice age in the southern hemisphere. I wonder if that ice age would have effected the southern hemisphere that much as only Antartica, Australia ,southern tips of Africa and South America would have froze over?

There is a good explanation on the site Real Climate started by Gavin Schmitt who is a former NASA climate scientist. The basic idea is that it is the Milanovitch cycles which trigger a new cycle of cooling that leads to an ice age. As the climate cools CO2 is taken in by the ocean. This causes a drop in atmospheric CO2 down to as low as 170 ppm. The reverse from the deep ice age is triggered again by Milanovitch cycles. Then as the earth begins warm the ocean temperature begins to rise and it releases CO2 back into the atmosphere as it warms. The CO2 level eventually reaches a stable point of 280 ppm. In this way CO2 amplifies the warming started by the M cycles. There many good KZitem videos that explain the Milanovitch cycles.

the milankovitch cycles didn't suddenly start 2.5mya. neither did the isthmus of panama close right then. There is a mechanism for asteroids to cause ice ages or impact winters- by injecting sun-blocking aerosols into the atmosphere. it's why the K-T extinction was so severe- after the global firestorm, a severe impact winter lasting years. seawater has a lot of sulfate in it, and sulfate is a major sun-blocker. The Chicxulub impact liberated a lot of gypsum (sulfate salt) and sulfide due to where it hit so this was a major contributor to its severity. likewise this impactor would have vaporized a lot of seawater.

An interesting story. But why would the story be that the impact blocked sunlight which led to the growth of glaciers rather than that the impact sent large volumes of ash into the atmosphere which settled on the ice causing the ice to melt due to the decreased albedo caused by dark dust on ice? I ask this even though the time period correlates to a glaciation. Also a lot of water vapor would have saturated the atmosphere from the impact. Water has a huge heat capacity. Any vaporized water would carry that heat into the atmosphere. The water would then cool down, releasing the heat back into the atmosphere so the total heat gain/loss by the impact vaporizing the water should mean that the total heat would not increase or decrease when you take the system of Earth as a whole. Is the story merely based on a correlation or did someone actually do the thermodynamic math?

In Henderson Nevada 15 miles from Las Vegas Nevada there's a Fisher call Black Mountain that originated from the Sierra Nevada mountain range fault line. when I was a young boy 7 years old I used to have dreams of it opening up and spitting lava. now I know this is not possible but it's lava made it this far from the fault line and did it once maybe it's possible we could do it again it was just wondering if you could break down the geology and timeline of when and how it was created

also there's some petroglyphs from old Indian civilizations throughout the area around the Western Southern base of the mountain

there are many ice ages, not one (referring to title, not description). In fact, the earth spends more time in Ice ages than in inter-glacial periods. Look up Milinkovic cycles.

@@ghoffmann821 A scientific theory needs a lot of supporting evidence and independent verification by other scientists to be valid. Until that occurs, it is a hypothesis (an idea). "been researched" is insufficient to be considered a theory. All hypothesis undergo research. Only a few become scientific theories.

3.7 to 3.0 million years ago, North and South America connected to block ocean currents that flowed through the gap. This blockage caused severe cooling in the Arctic Ocean.

actually, in some sense it warmed it, which may have been the problem, since it sent a lot of water vapor to high latitudes to fall over Eurasia as an incipient glacier. also the very salty tropical Atlantic water could release a lot of heat before an insulating layer of ice formed freezing, which enhanced cooling of the global climate by creating a more efficient conveyor as the dense salty water sank and also creating colder water that sank and then upwelled again at the equator, where it took even more heat to warm it up again

Nice to hear the term 'ice age' used to mean the couple of million most recent years within which there have been numerous glacial and interglacial periods. These glacial periods are often reported in the common press as ice ages and it leads to confusion over the demise of a whole rich fauna of animals in, for instance, the Americas starting about 12 thousand years ago. Many commentators surmise that the extinction was caused by the end of the so called ice age (the most recent glacial period), and completely ignore how these animals survived quite will, thank you very much, over numerous previous cycles of glacial-interglacial fluctuation. If the theory is correct there is a possible coming result. If we manage to melt the ice of Greenland and Antarctica so that the albedo of the planet decreases, perhaps we could bring a complete end to the most recent 2.75million year ice age with it's fluctuations between glacial and interglacial periods and shift the world into a more or less permanent warm period.

Zero chance that anyone could know of a future impact, let alone 14 years away, even if they know of a impact event happening..they couldn't pinpoint the exact area on earth like that. Even NASA always says of falling space debris "around the indian ocean". lol

The german borderscience author Hans Zillmer wrote something similar 15 years ago in his book "Kolumbus war der Letzte" (Columbus was the last): After the Younger Dryas impacts of a huge comet named Encke, that cause the biblical flood, about 12800 years ago, the huge amount of water blown into the atmosphere, came down as massive rain, mud, and snow in the far north and south regions. Therefore he named this centuries "Schneezeit" (snow age). This kms of thick snow then converted to ice, so that we today know it as ice age.
