Over the past century and a half, the concentration of hydrogen in the air has increased by more than 70%. This conclusion was reached by a group of scientists led by professor at the University of California at Irvine, Eric Zalzman, who studied ice samples in Antarctica that formed in the middle of the 19th century. According to climatologists, the increase in the proportion of hydrogen in the atmosphere has accelerated global warming.
“Our reconstruction shows that the proportion of hydrogen in the atmosphere remained almost unchanged until the end of the 19th century, after which it began to grow smoothly and grew by 70% by the beginning of this century,” says the article by the authors of this scientific work, published by the journal PNAS.
In addition, as the researchers note, they “recorded a sharp surge in hydrogen concentration at the end of the last century, whose existence casts doubt on the relationship between anthropogenic emissions of carbon monoxide and hydrogen.”
We will remind, as the website kp.ru wrote, earlier American scientists analyzed ice samples that were taken back in 2015 on the Guliya glacier in western China. In the ice, which formed 15 thousand years ago at an altitude of more than 6,700 meters above sea level, 33 viruses were detected, 28 of which were previously unknown.
It should be noted that scientists around the world are very concerned about the problem of climate warming. For example, the Pizol glacier in Switzerland has melted by almost 80% over the past 15 years. At the end of September 2019, environmentalists, tourists and local residents arranged a symbolic “funeral” for him, and before that, in August, a similar funeral ceremony for the 700-year-old glacier was held in Iceland.
