Scientists have warned of slowing ocean currents. The world has to take into account the extreme weather conditions

There is no need to worry about the rapid emergence of an ice age, as in the famous Hollywood movie, because the events there are exaggerated, but the slowing of ocean currents will slightly affect the weather in Europe and America. Winter will be colder, and we will see bigger heat waves and extreme weather fluctuations. “For decades, ocean currents have been expected to slow in the wake of global warming. We’ve now got the most convincing evidence that this is really happening,” said Stephan Ramstorff, CNN co-author of the Potsdam Institute for Climate Impact Research.

Scientists in recent years have even defined what it will mean for the planet’s inhabitants and slowed its speed. “The circulation of the marine current system has slowed 15% in recent years. In the next 20 or 30 years, it is likely to be more, which will inevitably affect our weather. In Europe, we will be able to see an increase in the number of storms and heat waves, and they will go up. Sea levels on the east coast of the United States. ” In their research, the experts analyzed data on the planet’s climate and the impacts of ocean currents over a period of about 1,600 years.

A critical situation could occur by the end of the century

Additionally, prediction models estimate that by the year 2100, ocean currents will slow by thirty-four to forty-five percent compared to normal. The answer to the question when will it stop completely, or how much slowdown will mean a global catastrophe, but according to Ramstorff, it is not clear. “Despite the rich research over the past decade, it is very difficult to determine the extent of the breaking point. Based on various models, I assume that if the circulation slows to half normal, then we reach a critical state. Something similar could happen by the end of this century,” he says. Rumstorff estimate for CNN.

Although many factors contribute to the slowdown of the large ocean currents, which are connected throughout the planet, one of the most important factors, according to the scientists, is global warming. For example, the Gulf Stream, also known as Arctic ice melt, is affected.

“The slowdown is not the result of natural change, but rather a result of a human influence. Evidence of a continuous slowdown in the current rotation is an important component of future predictions of regional and global climate,” said Andrew Myers, a polar explorer, to CNN. The researchers’ data also showed that temperatures in Europe and North America have been above average in recent years.

Marine currents are found in oceans around the world. Some are called hot, others are cold. Together, they form an inclusive system that has a major impact on the Earth’s climate and moves water between the oceans. Any changes in their operations would affect virtually all continents. And according to different dates, it is not possible to speak only in the future tense. “All the seven warmest years can be dated to 2014. We’ve had the ten warmest years on Earth since 2005,” CNN officials told the National Oceanic and Atmospheric Administration.

What are ocean currents and why are they important to us

Sea currents move water masses between oceans.

• It is a global circulation of water.

• Warm ocean currents flow from the equator to one of the poles.

Cold sea currents flow from the poles to the equator

• The operation of the marine current system affects the global climate and weather.

• Slowing down the entire marine current system can mean extreme weather fluctuations.
