Arctic extreme weather

Do you know that?/You know what? Do you know that?/You know what? The persistent extreme high temperature weather hit the whole northern hemisphere. The temperature in the Arctic Circle in northern Sweden once reached 30℃, and more than 10 forest fires caused by high temperature entered the Arctic Circle. The temperature in northern Siberia also reached 32℃. You know, in the same period last year, the average temperature in this area was only 10℃. Obviously, in this process, the earth is? Burning? The north pole is getting hot, too. When the monitoring department monitors the high temperature above 30℃ in the Arctic Circle of Sweden, it shows that there is rare high temperature weather in the Arctic Circle. The highest time reached 32℃, which also led to the rapid melting of glaciers. According to NASA data, in the past 40 years, the Arctic sea ice area in summer has been reduced by nearly half, leaving only about 3.5 million square kilometers, equivalent to 36.5% of China's land area.

Surprisingly, a huge iceberg cracked due to global warming and drifted to the edge of Inasut Island in the northwest of Greenland. On July 3rd1,2065438, a geography professor at Stockholm University in Sweden made a survey on Mount Kebner. Some scientists issued a statement saying that the glaciers on the south peak of Mount Kebner, Sweden's highest peak, were melting due to the record high temperature in the Arctic. This mountain is no longer the highest peak in Sweden. Later, Jennifer, a scholar studying Arctic meteorology, made the following prediction: In the summer before 2040, the ice on the Arctic Ocean may disappear completely, which is 60 years earlier than the countdown predicted by 10 years ago, and pointed out that the consequences brought by an ice-free Arctic may be unbearable for human beings. At that time, the tundra at high latitudes will turn green in advance, and the eggs will mature and migrate.

In recent years, frequent extreme weather seems to warn people again and again: global warming has become a huge challenge that all mankind must face at present, and the increase of greenhouse gases is the direct cause of this problem, while 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.

From this perspective, many people blame global warming for the first time. In fact, Mitchell of Bristol University once said that there is no doubt that it is hard to believe that climate change has not played a role in the current disaster. In addition, people should be careful not to exaggerate the impact of climate change, because we also realize that there are other factors at work, one of which is extreme wind jet. This is a fast moving air flow at a height of 7- 12km above the ground. It can blow warm and humid air from the Atlantic Ocean to Russia from west to east. When the jet is weak, it will be blocked by the counter-rotating airflow from Russia. When the airflow is strong.

For example, 20 10, which pulled a hot air stream from Africa, directly rushed into Russia, causing a large area of drought and nearly 800 wildfires. Other factors include dramatic changes in sea surface temperature in the North Atlantic. Professor Skye of the British Meteorological Office once said that this is part of the oscillation phenomenon in the Atlantic Ocean for decades.

Generally speaking, the two polar regions of the earth are in the polar circle. Because there is no direct sunlight in this area, the temperature in the polar regions is relatively low. Because direct sunlight will move back and forth between the Tropic of Cancer, the equator has become the place that receives the most solar radiation energy all year round, so the average temperature is relatively high. According to the monitoring data of the National Snow and Ice Data Center, the unusually high temperature accelerated the melting of the Arctic sea ice.

People can't help thinking that there are eggs under the nest. The high temperature of 32 degrees continues, and the Arctic ice begins to melt gradually, which is worrying. What will happen to polar bears who live entirely on ice? Hunger and drowning have become the norm for polar bears without ice. Relevant media have also reported that this town located at 67.5 degrees north latitude has reached a high temperature of 38 degrees Celsius. You know, this latitude is already in the Arctic Circle. No one expected that there would be such a high temperature in the polar regions of ice and snow in human impression, and the rare high temperature brought about forest fires. It is worth noting that although the Antarctic and the Arctic are snowy in the impression of most people, they also exist all year round.

From this point of view, the high temperature in the Arctic is normal, and the high temperature of 38 degrees Celsius has become the highest record in the history of the region. In fact, in this small town, there was a high temperature of 37.2 degrees Celsius or a low temperature of MINUS 68 degrees Celsius, and the maximum temperature difference was about 105 degrees Celsius. However, this time the distance has been broken, reminding us again that the global temperature is rising because of the greenhouse effect. At the beginning of this year, some scientists measured 20.

At the same time, in February, scientists also monitored more than 2 million methane hotspots in the Arctic, indicating that it is releasing methane into the atmosphere. Because methane is a stronger greenhouse gas than carbon dioxide, it forms a vicious circle. Presumably the last thing people want to see at this stage 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 industrialized society, the global average temperature has risen more than 65438 0.25 degrees Celsius, and this trend has not stopped and will continue to rise in the future. At this time, how can humans save our planet?
