How did we know the Ice Age cycle? (Milankovitch cycle)
#iceage #climatechange #milankovitch
Scientists have analyzed the ice sheets of Greenland and Antarctica. Furthermore, an analysis was conducted on the oxygen isotope ratio of seabed cores extracted from different seas. Based on the research conducted, it has been confirmed that significant glaciers exist in both Antarctica and the Northern Hemisphere. It has been discovered that there has been a regular recurrence of glacial and interglacial periods over the last 800,000 years. In this episode, I delve into the factors contributing to the cycle.

How did deep water flows of the oceans cool the Earth in the Ice Age?
Переглядів 10 тис.Рік тому
Throughout the history of planet Earth, there have been five distinct ice ages. Scientists have identified the key factors contributing to the planet's cooling during these periods. The first factor is Earth's orbit and Solar radiation. The second is the reduction of greenhouse gases such as carbon and methane. The third is the thermohaline circulation. Volcanic eruptions can also have short-te...

Переглядів 2,9 тис.Рік тому
After dinosaurs became extinct due to environmental changes caused by meteorite impacts at the end of the Cretaceous Period of the Mesozoic Era, the climate eased into the Tertiary Period. However, from the late Miocene onwards, the temperature gradually decreased, and glaciers began to appear. After the Pliocene, the temperature dropped even more as the Quaternary started to. As a result, Eart...

At the end of the last ice age, there was a time when glaciers reached their maximum. This period is called the Last Glacial Maximum, or LGM. After the LGM, glaciers melt over thousands of years. As a result, many changes have taken place in Fennoscandia. This episode introduces the Fennoscandia ice sheet's thawing and the first Scandinavians' migration.

    The conflict and war between close and related peoples and haplogroups R1a and R1b in Western Europe ended with the flight, the departure from Western Europe of representatives of the R1a peoples to Eastern Europe to the Russian Plain about 5,000 years ago.

    Trying to determine who is Jewish and who is not, by DNA etc, is probably impossible, because the Jews, after their expulsion from Palestine by Romans, 2000 years ago, lived in many European countries, and over the ages, tens of thousands of them, married and had children with women from various countries.

    A cycle of seven natural disasters create a cycle of five civilizations. Only one of them can develop 10,800 years and then it is wiped out by the next disaster. This cycle occurs worldwide following a fixed time schedule. The disasters change our world. Island appear and mountains disappear. So it is difficult to explain where humanity started. Planet 9 is the culprit. It encircles our sun in an eccentric orbit and when it crosses the ecliptic plane at a very high speed it causes a huge flood and other havoc. We explain much more about planet 9, the recurring flood cycle and its timeline, the rebirth of civilizations and ancient advanced technology in the e-book: "Planet 9 = Nibiru". It shows abundant and convincing evidence both in text and many depictions. It can be read on any computer, tablet or smartphone. Search: planet 9 roest

    You briefly mentioned the Neanderthals who were in Europe already by the time modern humans arrived there from Africa . The remote ancestors of the Neanderthals also came from Africa and migrated to other parts long before modern humans were born . Some 2.5 million years ago , these proto humans arrived in Europe and would evolve into the Neanderthal people , and THAT is why they say that the Neanderthals were in Europe for some 400, 000 years by the time homo sapiens arrived from Africa .

    Einstein is a fraud, his achievement is that he stole a patent from the office where he worked, based on which the atomic bomb was developed. The Zionist mafia that controls the media in the USA promoted him as a genius, no one, no one saw him solve the simplest equation. During spontaneous public speeches his main stance was to promote creating state of Israel and refused to answer scientific questions, which made the crowd in NY booed him out of stage. I watched this revealing documentary on Google Video in 2004, before Google took over YT and became part of the previously mentioned media mafia, where the truth is already difficult to find out.

    I don't believe it. I believe if man came from Africa then it's because we walked into it first from further north. Also, if man came from Africa then how come we only have a few bones, and to prove it, how come we have almost NO bones of the apes that lived in Europe, so in the past I believe a civilization in the north hunted apes and the apes left would keep heading south until they were stuck at the bottleneck that was Africa. I have a sculpture of an ape found in north east England but who made it.

    It is curious that in any presentation of the extent of the Ice age, two things appear to have been overlooked. First, it is clear that the 'icefication' of Europe was a result of the absence of the Gulf Stream and second, assuming that point why wouldn't the Atlantic completely freeze between Greenland, Iceland and England.
