Climate change is undeniable, the earth is heating up

In 2012, the global climate began to become unusual, and "extremely cold weather" became the focus of global attention. According to reports, parts of Europe have recently experienced the lowest temperatures in a century and the largest snowfall in decades, which has caused more than 500 deaths. The Danube River, which flows through Central Europe and the Balkan Peninsula, froze, paralyzing shipping in six countries along the coast: Hungary, Austria, Bulgaria, Croatia, Romania and Serbia. In Asia, Japan and South Korea have also been hit by frequent heavy snowfalls, with snow accumulations reaching three to four meters thick and avalanches occurring in many places. Seoul, the capital of South Korea, has experienced its lowest temperature in 55 years, and snowstorms have killed at least 63 people in Japan. The lowest temperature in some areas of Inner Mongolia and Heilongjiang fell below minus 40°C. On January 30, the daily lowest temperature in Chenbalhu Banner, Inner Mongolia, reached minus 45.5°C. According to US media reports, some authoritative international climate experts pointed out that the recent extreme cold in Europe and Asia is just the beginning of global colder weather, and such cold weather may last for 20 to 30 years. Some media even claimed that this year's cold winter showed that "the Earth's Little Ice Age may have arrived." Isn’t it said that the world is warming? Why does it get colder? Will mankind really continue to face the test of extreme cold? Extreme weather Global warming is the underlying cause of extremely cold weather. The melting of Arctic sea ice has brought Arctic weather to Eurasia. Recently, the Japan Marine Research and Development Agency released the results of a cold weather survey, believing that climate warming has brought Arctic weather to the Arctic Circle. The sea ice in the Lonzi Sea decreased, causing the low pressure to move northward, and the Siberian high pressure expanded, forming strong cold air to hit Japan. The Barents Sea is located north of Norway and Russia and is one of the continental marginal seas of the Arctic Ocean. The sea ice area in this area usually reaches 60% to 70%, but this winter it is only 34% to 35%. At the same time, European scientists expressed similar views on the cold snap experienced in Europe. Ramsdorf of the Potsdam Institute for Climate Impact Research in Germany told the British Independent that due to climate warming, the volume of the Arctic ice sheet has decreased by 20% in the past 30 years. Once the polar ocean lacks ice www.gesep.com energy-saving coverage, the relatively warm air on the sea surface will move to cold high altitudes, affecting the polar atmospheric circulation. The result is that the polar cold air is driven by the high-pressure system and moves toward the continental areas of the northern hemisphere. , causing local temperatures to plummet. "Global warming is the underlying cause of this extreme cold weather. The melting of Arctic sea ice has brought Arctic weather to Eurasia." Du Yaodong, chief expert of the Guangdong Provincial Meteorological Department and researcher at the Guangdong Provincial Climate Center, told the Southern Daily reporter. "The world's climate experts have basically agreed on the cause of this extreme cold weather.

"The relevant person in charge of the Guangdong Provincial Meteorological Bureau said that since the beginning of 2012, there have been obvious abnormalities in the atmospheric circulation. The main manifestations are that the Siberian high pressure is stronger, the height field in the middle troposphere and mid-high latitudes in Eurasia is higher in the west and lower in the east, and the circulation is higher in the west and lower in the east. This atmospheric circulation situation is large in direction and is conducive to the spread of cold air in the Arctic region, which leads to outbursts in Europe and East Asia.
