There are still many unexplored places on planet Earth that keep many secrets. The solution to the latter will allow humanity look into the past and learn about how the world was in the deep antiquities. One of these places, of course, is Antarctica.
For many years, scientists from all over the world have sent to this continent is a research expedition. Some of they manage to get valuable information that instantly becomes a sensation in the scientific world. But most expeditions, to Unfortunately, they return home with nothing. Well, “Terra Incognita”, that is, “Unknown Land”, does not reveal its secrets to everyone. However, the few discoveries that were made on its territory can tell a lot.
Recently, Antarctica presented scientists, perhaps, one of the most significant gifts lately. During the next expedition a team of researchers found a bubble in an ice block in which contains very ancient air. According to scientists, he is about 1 million years
Air from the distant past, mothballed in the form of a bubble, provided researchers of Antarctic ice a unique opportunity. Namely, to find out what climate reigned on the Earth. about 1 million years ago.
An unusual bubble was discovered in the Antarctic region. Allan Hills, next to which is a research McMurdo station. After analyzing the composition of the ancient air, scientists found that it contains not only carbon dioxide, but also methane. The data obtained allowed scientists to come to the following conclusion – it turns out, 800 thousand years ago, in the so-called interglacial period, on Earth there were no significant changes in the level of greenhouse gases.
The data obtained indicate that over the last while the level of carbon dioxide in the atmosphere increased by 100 ppm. Then is, in our time it is 400 ppm. And 1 million years ago this the rate did not exceed 300 ppm. All this suggests that on Earth the environmental situation has deteriorated very much. Scientists warn that if humanity does not take any measures, the level of carbon dioxide in the atmosphere will increase more at a fast pace.
