Tracks from the past

It is very difficult to predict the future climate of the world, but it is much easier to look back. As a result of research from the deserts to the poles around the globe, scientists have discovered that the climate has never remained the same for a long time. Some of these changes have taken place in thousands or millions of years, and some have been much faster. Rapid changes are very important because it is very difficult for people to survive in such periods.

Prehistoric paintings

Prehistoric rock paintings were found in Tassili N’Ajjer in the Sahara Desert. In these paintings, made about 6,000 years ago, the Sahara is shown as a fertile area covered with wildlife.

WARMING AND FREEZING

These ruins in Greenland-Brattahlid belong to a Viking settlement that discovered the site about 1000 years ago. When the Vikings discovered Greenland, the Earth’s climate was going through a period of warming. The Vikings started farming on the icy southern coast of Greenland and lived in stone-built houses. Initially, the settlements were successful, but slowly their luck began to spin. In the next 300 years, the cold came back slowly, and the Vikings could not grow enough crops. As a result of the long battle against hunger, Greenland’s last Viking died.

POLE CROPS

The fern fossil was found in Antarctica, the coldest continent in the world. It was found that the fossil was millions of years old when Antarctica was closer to the north than today. The climate was warm enough for the plants to grow and they even had their own dinosaurs. Antarctica lost to the south, and these plants and animals died slowly when they began to be covered with ice. (Astropical: Close to tropical regions, but at a higher latitude)

THE SECRET SECRET IN

The layers of ice on earth are formed by the accumulation and hardening of the snow falling over millions of years. Scientists take samples of ice and examine the recordings of ice on Earth’s history dating back millions of years. Some samples are taken from areas close to the surface, while others are taken at a depth of 2 km or more with power drills. Ice samples taken from the deep have prehistoric air bubbles. The substances in these bubbles provide scientists with very important data on the greenhouse effect.

All Natural Disasters

Many people like the excitement of fear. That's why Natural disaster movies are so popular. But in real life, Natural disasters are very different from those in movies. and it is unlikely that heroes will be boldly celebrated in the most difficult situations. Even with today's advanced technologies, it is not easy to predict disasters. Therefore, natural disasters often cause loss of life and the effects of destruction last for years.
