Increasingly cold winter, affordable paradox?

Europe, North America and many parts of Asia are experiencing a harsh winter, with temperatures dropping to record levels, snow and ice making traffic stagnant. According to scientists, such winters will become more and more popular in the future due to global warming.

How are these two contradictory phenomena explained by scientists?

This year, the people of many states on the east coast of the United States must celebrate Christmas and New Year in the house. In New York, nearly 50cm of snow makes airports closed, more than 2,000 flights canceled. The states of Massachusetts, Maine, Maryland, New Jersey, etc. are placed in an emergency. The two southern states of Georgia and South Carolina have celebrated Christmas with the first snow in the past century.

Previously, cold and snow storms were resolved through Europe and many North Asian countries. French Charles de Gaulle Airport the days before and during Christmas looks like a barracks with hundreds of folding beds and blankets given to those who missed the flight.

Traffic in Belgium, Germany, England, and Italy interrupted locally in many places due to snow. In Russia, more than 400,000 people living around Matcow suffer from long hours of freezing electricity. In China's Inner Mongolia autonomous region, snow has appeared about 40 days earlier than usual and falls the thickest in 30 years, causing the lives of tens of thousands of people to turn upside down. In many places, snow falls more than 1 meter thick.

Conflict with global warming?

No, nothing is contradictory, it's paradox. Although these frozen winters may be more than three times in the near future.

What is happening in Europe, North America and North Asia is described by many media by the word ' unusual '. However, according to scientists at the Potsdam Institute for Climate Impact Research (Germany), severe winters will soon become normal in the future. And the cause is a phenomenon that just sounds very contradictory. That is global warming.

The temperature of the Earth is increasing and by 2100 it will be about 5-6 degrees Celsius higher than today. But that does not mean that year-round weather anywhere in the world will be warmer. On the contrary, it could triple the risk of freezing winter in Europe and North Asian countries.

Explaining this problem, Dr. Stefan Rahmtorf, an expert in Potsdam, said that the temperature rise in the Arctic (at a rate of 2-3 times higher than the global average) has caused the ice Here is 20% thinner in the last 3 decades. If this situation continues, by 2100, ice in many parts of the Arctic may melt completely in the summer.

Melting ice, the Arctic Sea loses its precious cover, so the amount of solar radiation absorbed by the sea will be higher. This heat makes the sea water warm up. In winter, the temperature of seawater may be 0 degrees Celsius, much warmer than the upper air layer. The result of this transformation process is a strong high-pressure system that forms above the sea areas exposed by melting ice, bringing the cold air of the polar, anticlockwise to Europe.

The harsh winters, as happened in 2005-2006 and last year, clearly demonstrated that this claim was in fact. In theory, the computer model simulating the effects of melting ice in the Barents-Kara region and northern Scandinavia also shows the link between global warming and icy winters.

Thus, colder winters are not a sign that global warming is slowing. On the contrary, it is a consequence of global warming, and both are happening with an increasing trend. Even in these days, when in Germany, the temperature is -14 degrees Celsius and the snow is 30 cm thick in Greenland, the weather is unusually warm with temperatures above 0 degrees C.
