Before the start of the Eocene Epoch about 56 million years ago--Antarctica was still joined to both Australia and South America. And it turns out that a lot of what we recognize about the southern hemisphere can be traced back to that time when Antarctica was green.

A holdover from when their spaces where full of green savanna before the desertification of large portions of Africa. Antarctica would have looked similar, except in this instance the desert ends up winning.

Norway should get exclusive control over the south pole, and about a circular 50 miles surrounding it on the Polar Plateau, since Amundsen effectively was the man to first conquer the North Pole.

Like the classic case of believing that Greenland is the size of Africa because of the Mercator projection.

Johannes Sigurdsson during the PETM, places near the equator we’re very hot, remember, 56 million years ago, Earth was about 5-9°C hotter than today. But with modern global warming, we could see a preview by 2100. Lol
@hanselsihotang 3 жыл бұрын
Probably very hot and humid, just like today's tropical forest, but on steroids since the temperature was several degrees Celcius higher. For a modern human living in it must've felt like hell.
@AlexAnder-rv1gu 3 жыл бұрын
It would've been hotter to an extent, yes. But remember that those temperature differentials are averages for the whole planet - much like they are today. So while one place may vary greatly in temperature, others may not. They explained that the major reason for the cooling of Antarctica was the breaking away of other continents, leaving it to develop a sea that surrounds it. Therefore today as the world begins to warm, Antarctica will never become the warm temperate place it once was because there are other geological factors at play affecting it's temperature. In that same sense, a long time ago when Antarctica was more temperate, that doesn't necessarily mean that the equatorial regions were furnaces - they would've had other factors such as wind and sea currents which would mediate their temperature levels. And the global temperature change would've been most represented in certain areas, not all equally. Think of it like a Neanderthal in ice-age Europe saying "man, when this ice-age is over, I wouldn't wanna live in Equatorial Brazil! It'd be hella hot!" But not all regions gain/lose an equal amount of temperature, so humans managed to live there regardless.

What was the Earth's tilt during this time and how did it effect the climate of the continent?
@VictorbrineSC 4 жыл бұрын
Likely 23 degrees as it has always been since the formation of the Moon. The Moon stabilized our axis to 23 degrees. It makes a procession every 100 thousand years I think (don't remember the exact number, could be more or less) so the seasons shift along the orbit as time passes, which could have caused some changes in climate over millions of years. But during that time the axial tilt was likely 23 degrees, like today.
@connordrake5713 4 жыл бұрын
Earth's tilt is always changing because of earthquakes. The last earthquake in Indonesia change the Earth tilt a little bit. So it's hard to predict the Earth's tilt before since it is dynamic overtime.
@jonathanh222 4 жыл бұрын
The changes in tilt from earthquakes are way way too small to have any impact on climate. The tilt is basically static, even though technically it isn't

The Chandler wobble or variation of latitude is a small deviation in the Earth's axis of rotation relative to the solid earth, which was discovered by American astronomer Seth Carlo Chandler in 1891
@PremierCCGuyMMXVI 4 жыл бұрын
Raoul Simon it varied a lot in the PETM, it’s peak hearing lasted only 700,000 years but the warm period witch was 6-9°C hotter than today. Lasted tens of millions of years. So you probably did have cooling and warming from the orbital cycles. But what kept Earth was CO2 around 900-1,000 ppm (today it’s only 415 ppm but with human caused global warming, it could be as high as that by end century) most of the time a major climate change event will occur because of the composition of Earths atmosphere. What lead to the PETM cooling after was because CO2 was being sank to the ocean thanks to microbes, Antarctica and arctic isolating itself causing glaciers to form causing cooling and the formation of the Himalayas due to India colliding with Asia, exposing Rock, drawing carbon from the air cooling the planet.

It is incredible to think that the ancestors of the Kangaroo had once set out from South America. Absolutely fascinating. Keep up the great work! Oh and also could you do a video on the Sahara and the last time that it was green....and what role it might have played in Human evolution and migrations.
