A rare high temperature occurs in the Arctic Circle: 32 degrees Celsius, the global temperature enters "fever" mode?
Did you know? Sustained extreme high temperature weather has hit the entire northern hemisphere. The temperature in the Arctic Circle in northern Sweden once reached 30°C. More than 10 forest fires caused by high temperatures burned into the Arctic Circle. The temperature in northern Siberia has also reached 32°C. You need to know During the same period in previous years, the average temperature in this area was only 10°C. Obviously, the earth was "burning" during this process, and the Arctic was also heating up. When the monitoring department detected a high temperature of over 30°C in the territory of the Swedish Arctic Circle, This shows that rare high-temperature weather has occurred in the Arctic Circle. The highest temperature once reached 32°C, which also caused the glaciers to melt rapidly. NASA data has shown that in the past 40 years, the Arctic summer sea ice area has reduced by nearly half. Only about 3.5 million square kilometers remain, equivalent to 36.5% of my country's land area.
Astonishingly, a huge iceberg calved due to global warming and drifted to the edge of Inasut Island in northwest Greenland. On July 31, 2018, researchers at Stockholm University in Sweden After a geography professor made measurements on Kebneberg, scientists issued a statement saying that due to the record-breaking high temperatures in the Arctic, the glaciers on the south peak of Kebneberg, Sweden's highest peak, are melting. This mountain is no longer Sweden's highest. Later, Jennifer, a scholar who studies Arctic meteorology, made the following prediction: Some summer before 2040, the ice in the Arctic Ocean may completely disappear, which is 60 years earlier than the countdown predicted more than 10 years ago, and pointed out The consequences of an ice-free Arctic may be unbearable for humans. At that time, the tundra in high latitudes will turn green in advance, insect eggs will mature prematurely, migrating birds will miss the time to forage, and polar animals will face the end of drowning. , a heat wave will sweep through Northern Europe, and the Rhone glacier in Switzerland will be covered with insulating foam to prevent it from melting.
In recent years, frequent extreme weather seems to be warning people again and again: global warming has become a huge challenge that all mankind must face together, and the increase in greenhouse gases is The direct cause of this problem, and human industrial activities and the use of fossil fuels are the root causes of this problem. Therefore, most people say that reducing pollutants and greenhouse gas emissions and vigorously developing clean energy are the only way to deal with climate change. .
It seems that many people have immediately attributed this wave of enthusiasm to global warming. In fact, Mitchell from the University of Bristol once said that there is no doubt that the current trend is related to global warming. In terms of disasters, it is hard to believe that climate change did not play a role. Furthermore, one should be careful not to exaggerate the impact of climate change, because we are also aware that there are other factors at play, one of which is extreme winds. This is a fast-moving air flow at an altitude of 7-12 kilometers above the ground. It can blow the warm and moist air from the Atlantic Ocean from west to east to Russia. When the jet is weak, it will be blown by Russia's counter-rotating air flow. Blocking, when the jet is strong.
For example, in 2010, it brought a stream of hot air from Africa directly into Russia, causing widespread drought and nearly 800 wildfires. Other factors included huge sea surface temperatures in the North Atlantic. The change, Professor Scaife of the Met Office has said, is part of a multi-decade oscillation in the Atlantic Ocean.
Generally speaking, the two poles of the earth refer to the polar circle. Since this area does not have the opportunity for direct sunlight, the temperature at the two poles is relatively low, and because the direct sunlight will Reciprocating between the Tropic of Cancer and the Tropic of Cancer, the equator has become the place that receives the most solar radiation throughout the year. Therefore, the average temperature is relatively high. According to monitoring data from the National Snow and Ice Data Center of the United States, abnormal High temperatures are accelerating the melting of Arctic sea ice, which may in turn lead to further intensification of abnormal weather.
People can’t help but think of the intact eggs under the overturned nest. When the high temperature of 32 degrees continues, the Arctic ice also begins to gradually melt, which makes people worry about polar bears that completely rely on ice to survive. Where to go from here? Because polar bears have no ice to rely on, starvation and drowning have become the norm. Relevant media have also reported that a small town located at 67.5 degrees north latitude reached a high temperature of 38 degrees Celsius. You must know that this latitude is already within the Arctic Circle. No one can I never thought that such high temperatures would occur in the polar regions of ice and snow that humans have in mind, and the rare high temperatures have brought about forest fires. It is worth noting that although the Antarctic and the North Pole are ice and snow in most people's impressions, they also exist for a year. four seasons.
From this perspective, high temperatures in the Arctic are normal. The high temperature of 38 degrees Celsius has become the highest in the history of the region. In fact, in this small town, there have been high temperatures of 37.2 degrees Celsius or below zero. With a low temperature of 68 degrees Celsius, the maximum temperature difference is about 105 degrees Celsius. However, this time the distance has been broken again, reminding us once again that global temperatures are rising due to the greenhouse effect. At the beginning of this year, scientists measured a high temperature of 20.75 degrees Celsius in Antarctica. , the highest temperature ever recorded in that area.
At the same time, in February, scientists also monitored more than 2 million methane hotspots in the Arctic, which shows that it is releasing methane into the atmosphere, because methane is a greenhouse gas more powerful than carbon dioxide. , thus forming a vicious cycle. Presumably, the last thing people at this stage want to see is the high temperature on the earth, because it reminds us all the time that the damage to the environment has begun to appear. Since the industrialization of society, , the global average temperature has risen above 1.25 degrees Celsius, and this trend has not stopped and will continue to rise in the future. At this time, how can humans save our earth?
