Climate change has led to an increase in freshwater in the Arctic Ocean

Scientists from the United States have analyzed the global processes that occur with fresh water in the Arctic Ocean. They found that its volume is increasing due to global warming, this will affect the ecosystem of the entire planet.

Research by the University of Colorado found that climate change is increasing the amount of freshwater in the Arctic Ocean. Over the next decades, this will lead to an increase in the volume of freshwater in the North Atlantic, which could disrupt ocean currents and affect temperatures throughout Europe.

Scientists have published details of their research in the scientific journal Geophysical Research Letters. They looked at the increase in freshwater supplies in the Arctic over the past two decades and drew conclusions about how this will affect the planet in the future.

The researchers noticed that the freshwater level in the Arctic Ocean has increased by 10% since the 1990s. This is 10 thousand cubic km. water.

“We hear a lot about changes in the Arctic in terms of temperature, and how this will affect ecosystems and animals. But our study provides an additional dimension – how the increase in freshwater will affect ocean circulation and climate”.

Such changes have occurred before, for example, in the 1970s and 80s. However, these were temporary phenomena, later the level of fresh and salty water returned to normal. This time, the trend does not change, and if this continues in the future, the circulation of water in the ocean may be disrupted forever. This could have negative consequences for the climate and ecosystems of the North Atlantic and the entire planet.

However, freshwater prevents the rest of the ocean from cooling: it keeps cold water on the surface instead of allowing denser liquid to sink below. Thus, the structure of the water in the Arctic Ocean differs significantly from other oceans. This mechanism can also disrupt ocean currents in the North Atlantic.
