Mr. Nerd

Have you ever traveled in the North Pole? How does it feel to be cold outside? But maybe if you lived at a time 56 million years ago, you might have a different feeling.That's because tens of millions of years ago, the Earth fell into a global warming period and is also known as the Paleo-Eocene Thermal Maximum. During this period, the Earth's temperature was so hot that both poles reached temperatures near the tropical zone. In other words both today's Arctic and Antarctica also have hot temperatures and tropical landscapes.The Earth has experienced extremely hot periods many times. Especially the poles also froze and thawed countless. Now the Earth is heating up but very different from the old days. It is also a hot form like old times. But now there is more impact of climate change. This leads to a record high temperature every month.The Earth's climate has fluctuated naturally over the past tens of thousands of years, the planet's rings around the Sun gradually changing. It leads to a change from season to light. Part of the result of these fluctuations is that the Earth experienced ice ages and warmer periods.But to create a Paleo-Eocene breed would need more than a change in the tilt of the Earth axis or its movement around the Sun. But besides, another invisible culprit could create a typical climate of the Paleo-Eocene period, which is CO2.Greenhouse gases, including CO2, are responsible for causing high temperatures throughout the planet's surfaces during the Paleo-Eocene period. But how to increase CO2 concentration without human appearance? Scientists seem not quite sure.Sébastien Castelltort, a geologist at the University of Geneva, said: "The cause may be due to the active volcanoes, the release of CO2 into the atmosphere." The CO2 then covered the Earth and caused sunlight to escape. Thereby causing the Earth to warm up, freeing the ice mountains at the two poles. When the polar ice sheets dissipate, methane gas, a greenhouse gas that is much more toxic than CO2, accidentally escapes.For example, the extinction event in the Permian-Triassic period, occurred several million years before the dinosaurs rose and mastered the planet. It is really a major climate disaster for Earth. This warming event took place 252 million years ago and was extremely serious. This event is caused by volcanic activity that causes climate chaos and destruction of many species.Paleontologist Stuart Sutherland of the University of British Columbia told Live Science that a serious drought occurred at that time. All plants die and the Saharah desert spreads throughout the continent. The temperature at that time was almost beyond the tolerance of all species.It is unclear how Permian-Triassic greenhouse gas concentrations are but they are much higher than today. Some climate models predict that the greenhouse gas concentration may then have reached 3,500 parts per million ppm. Meanwhile, there are now only 400ppm.But to lead to the Permian-Triassic extinction event, the Earth has spent thousands of years in order to reach such a terrible temperature. Specifically, according to some studies, time can last up to 150 thousand years. In the Paleo-Eocene period, the temperature can increase extremely fast when it takes only 10-20 thousand years to achieve such a terrible temperature.Warming on Earth today seems to take only 150 years.That is the big difference between climate change and the situation of global warming today compared to the phenomenon of global warming in the past. Extremely fast and extreme developments make the consequences of climate change now extremely difficult to predict.Castelltort said that his concern at this time is not only that the planet is heating up but also that we don't know that everything is turning so fast that people cannot adapt.There is no climate expert who dares to assert that the current warming speed of the Earth does not have any serious consequences, he said. Only we don't know how the future climate scenario will happen.
