Water temperature in the Atlantic Ocean has broken a record in thousands of years

The water temperature in the Atlantic Ocean has broken a record for at least the last 2900 years.

This conclusion was made by scientists from the United States and Canada, according to a study by the NAS of the United States.

Experts emphasize that changes in recent decades indicate that the process has moved beyond natural fluctuations.

For example, scientists from the University of Massachusetts and the University of Quebec have tracked temperature fluctuations in the Atlantic for about 2,900 years by studying sediment cores (samples of solid matter in the form of a cylindrical column) in the Canadian Arctic.

Ice deposits were taken from Lake Ellesmere, as temperature changes strongly affect this region. Warmer water increases the pressure, resulting in reduced snow depth. This, in turn, means less sediment runoff. Sediment cores have shown regular increases and decreases in Atlantic temperatures, and that ocean warming rates have increased over the past decade.

They also compared cores from different locations, including cores off Iceland’s southern coastline, which has spanned the past 230 years. The results show that “the recent warming in the Atlantic is unmatched” for at least 2,900 years.

Earlier we wrote that December 2019 was the warmest winter month in the history of mankind.

In addition, it was reported that the coldest continent of the planet — Antarctica, is undergoing climatic changes, as a result of which a new ecosystem may form. Researchers have discovered algae on top of melting snow in Antarctica.
