Nearly 4 million years ago, the sea level was higher than 16m

The new discovery of sea level in the Upper Body can help scientists more accurately predict future climate change.

An international team of scientists have found ancient quarries inside the Artà cave, located on the Spanish island of Mallorca, showing that the sea level 3.5 to 4 million years ago was more than 16 meters high. Compared to today, UPI August 30 reported. At that time, the temperature on Earth was 2 to 3 degrees warmer.

The study focused on the formation of sedimentary layers by caves. The scientists collected 70 mineral samples and carefully analyzed them in the laboratory. They used radioactive isotope uranium – lead to determine the origin and date of the samples.

The results show that the sedimentary layers have been from the Upper Tan (the second century of the Tan Can, in the Tan Sinh period) and were formed under the influence of salt water and air inside the cave. This shows that the Artà Cave, now more than 100 meters deep inland, was once inundated with sea water, explains Professor Joan J. Fornós from Illes Balears University.

“Sea level changes in Artà caves may be caused by the growth and melting of the ice sheets, or caused by the island’s rising and subsidence process,” said Professor Jacky Austermann from Columbia University, Another member of the team adds. Based on the melting ice models, the team said that the collapse of two large ice sheets in Greenland and West Antarctica was the main cause of sea level rise in recent years.

The study involved scientists from the University of New Mexico, the University of South Florida, Columbia University of the United States and Illes Balears University of Spain.

Surprised by the sight of the only poisonous snake in the UK “crying out”.

Every phenomenal thing in life will be important to this person, but it is unlikely that others have felt that way. On the contrary, there are things we find normal, even frightening, but to a community it is sacred and meaningful.

This is at least true for the moment below. It was a video taken by photographer Dominic Greves, recording the image is said to be super rare: a young snake coming out of the mucous membrane, breathing the fresh air of nature for the first time.

Specifically, Greves said he initially saw the mother snake lying in the nest. The mother snake is moving, crawling away, leaving a pouch of amniotic fluid with the baby inside. The snake after a few attempts, finally chiseled amniotic sac, crawled out.

The sight of snakes coming out of their wraps can scare many people. However, this moment for science and nature lovers is really meaningful. Because it is the snake adder – the only poison snake in the UK.

“We saw a big snake lying in a rock. The snake was moving, crawled away, and soon we found the young snake in the amniotic sac right where the mother had just left.”

“A few minutes later, the serpent squirmed around, went through the amniotic fluid and was officially born.”

Reportedly, the snake adder, scientifically known as Vipera berus, is the only poisonous snake in the UK and has an average life span of about 15 years. Because of its rare nature, the British have made a law to protect this snake. In the UK, it is illegal to intentionally injure or kill a snake.

Visually, this snake does not lay eggs but give birth to children. But in fact, they hatch eggs right in the abdomen, so when giving birth may young snakes still attached to the amniotic sac.

“No one in my conservation group has ever seen this scene. There are no similar scenes online including the captive environment, not in the wild like this time.” – Greves said.

“This is also the first time after 10 years of working in my UK”.
