Global warming changes the ocean flow

The period of Earth's surface temperature heating up from 55 million years ago was the main cause of changes in ocean currents. This is the conclusion of US researchers.

Ocean currents have changed when the temperature of the earth heats up

Scientists at the Scrip Institute of Oceanography at the University of Caliphonia after measuring carbon 13 isotopes in samples taken at 14 points in all four oceans, found that 55 million years ago, the temperature of the Earth's surface increasing from 5 - 8oC in a very short period has upset the ocean's low-flow flows.

The entire system of these flows only "walks" halfway through its journey and back.

Before the rise of the Earth's temperature, low-level currents in the ocean "turned" in the southern hemisphere, but during the next 40,000 years, when the Earth's temperature increased, the currents did not flow to the Southern Hemisphere that flipped back right in the northern hemisphere.

Nearly 100,000 years later they returned to normal.

It is unclear what causes the Earth to heat up during this period. Among the hypotheses, scientists pay attention to traces of volcanic eruptions that release trillions of carbon dioxide (CO2).

This finding is of special importance, although it happened tens of millions of years ago, but its lesson is still new. Scientists have added evidence that humans will continue to suffer from the serious consequences of discharging CO2 into the atmosphere by using fossil fuels.

This study reinforces a previous finding, published in November 2005, that climate warming is slowing down the flow rate of the Gulf Stream in the Atlantic while using this flow first. Now Western Europe has a milder climate.

According to the latest data from the United Nations Climate Price Specialist Group, from now until 2100, the Earth's surface temperature may increase 1.4 - 5.8oC compared to 1990.
