Greenland loses about 6 billion tons of ice every day due to the unusually high temperature.

Greenland loses about 6 billion tons of ice every day due to the unusually high temperature. Greenland ice sheet is the second largest ice sheet in the world, with an area of nearly 6.5438+0.8 million square kilometers, second only to the Antarctic ice sheet. Greenland loses about 6 billion tons of ice every day due to the unusually high temperature.

The daily ice loss caused by rare high temperature in Greenland has reached about 6 billion tons 1. This summer, many countries in the northern hemisphere suffered from high temperature "baking", and many places set new high temperature extremes. In Greenland, most areas are located in the Arctic Circle, and glaciers are melting at an unprecedented rate.

According to CNN's report on the 20th, the recent unusually warm weather in northern Greenland caused glaciers to melt rapidly, and meltwater rivers could be seen flowing into the ocean. Scientists say that the local temperature has been around 60 degrees Fahrenheit (about 15.56 degrees Celsius) recently, which is much higher than the normal temperature in the same period.

According to the National Snow and Ice Data Center, during the period from July 15 to July 17, Greenland melted enough ice (6 billion tons per day) to fill 7.2 million Olympic standard swimming pools. In other words, this water is enough to cover one foot (30.48 cm) in West Virginia, USA.

Ted Scambos, a senior research scientist at the National Snow and Ice Data Center of the University of Colorado, said that from the average climate level of the past 30 to 40 years, the melting in the past week was abnormal, "but the melting has been increasing".

According to the report, every summer, scientists worry that a record melting like 20 19 will happen again-at that time, 532 billion tons of ice melted and flowed into the sea. The warm spring of that year and the heat wave in July caused almost the whole ice sheet surface to melt, and the global sea level rose permanently1.5 mm. On the other hand, Greenland has enough ice-if all the ice melts, it can raise the global sea level by 7.5 meters.

Greenland loses about 6 billion tons of ice every day due to the unusually high temperature. Recently, there has been a large area of extreme high temperature all over the world, which is also the most worrying problem of ice sheet melting.

According to @ CCTV News, CNN reported that the ice sheet covering Greenland, the world's largest island, is melting in a large area due to the recent rare high temperature weather in many European countries.

From July 15 to July 17, the daily ice loss has reached about 6 billion tons, enough to fill 7.2 million Olympic swimming pools.

It is reported that the Greenland ice sheet is the second largest ice sheet in the world, with an area of nearly 6,543.8+0.8 million square kilometers, second only to the Antarctic ice sheet, accounting for 654.38+0.9% of the world's total glaciers.

Generally speaking, June to early September is the season when the Greenland ice sheet melts. However, the temperature has been "unusually warm" recently, reaching above 15℃, and even journalists can wear short sleeves to go out, which has obviously accelerated the ice melting speed in Greenland.

Glacier melting is considered as a measure of global warming. Climate change experts have long warned that global warming will lead to melting glaciers and rising sea levels, which may destroy coastal countries and island countries.

According to the calculation data, if all the snow-capped mountains in Greenland melt, the global sea level will rise by 7.5 meters, and the delta and some islands will be submerged.

Greenland loses about 6 billion tons of ice every day due to the unusually high temperature. According to CCTV's financial report, CNN recently reported that the ice sheet covering Greenland, the world's largest island, is melting in a large area due to the rare high temperature weather in many European countries recently. From July 15 to July 17, the daily ice loss reached about 6 billion tons, enough to fill 7.2 million Olympic swimming pools.

Is Greenland hot enough to wear short-sleeved shorts?

It is reported that the Greenland ice sheet is the second largest ice sheet in the world, with an area of nearly 6.5438+0.8 million square kilometers, second only to the Antarctic ice sheet, and the annual average temperature is below 0 degrees Celsius. Generally speaking, June to early September is the season when the Greenland ice sheet melts. However, the unusually warm weather in recent days has accelerated the melting of ice in Greenland.

CNN reporter René Marsh said that the temperature in Greenland was very high on 19, close to 60 degrees Fahrenheit (about 15.5 degrees Celsius), which allowed me to wear short-sleeved shirts to go out. The unusually warm temperature accelerated the melting.

Kutalmis Saylam, a researcher at the University of Texas in Greenland, said: This worries me. Yesterday we even walked around in our shirts, which we never thought of.

Due to the abnormal temperature and soft ice, the plane could not take off and land normally, and some local researchers even played volleyball in shorts.

According to the data of the National Snow Data Research Center of the United States, from June 15 to June 17, the Greenland ice sheet lost about 6 billion tons of ice every day, enough to fill 7.2 million Olympic swimming pools. Researchers from the University of Texas in Greenland said that due to the rising temperature, the total melting amount of Greenland ice sheet is amazing, and even the sound of melting ice can be heard.

If all the snow-capped mountains in Greenland melt

The global sea level will rise by 7.5 meters

According to Zhongxin. Com, in 20 19, an unprecedented snow melting event occurred in Greenland, and 532 billion tons of water flowed into the sea, resulting in a permanent rise of global sea level 1.5 mm.

Research published in February 2022 showed that the bottom of the Greenland ice sheet melted at an "unprecedented" speed. If all the snow-capped mountains in Greenland melt, the global sea level will rise by 7.5 meters.

Since1980s, Greenland has been warming about 0.8 degrees Celsius every decade, which is four times faster than global warming.

Last year, Danish researchers said that the melting rate of Greenland ice sheet accelerated after 2000. It is understood that most of Greenland is located in the Arctic Circle, and about 80% of the land on the island is covered by ice sheets.

On June 5438+09, the World Meteorological Organization (WMO) pointed out that the rare high-temperature weather that swept through Europe recently may become the "standard" in European summer, and the negative effects of climate change such as high temperature will last at least until the 1960s, and the global glacier melting trend will last for hundreds of years or even longer.

Extreme high temperatures often occur in many parts of the world.

According to the Beijing News, June 5438+1October-March is the summer in Argentina, Uruguay, Paraguay and Brazil. These countries witnessed the historic heat wave in June 5438+1October this year. In June 5438+10, the temperature in Western Australia was as high as 50.7 degrees Celsius, which was the same as the highest temperature reliably recorded in the southern hemisphere. In Asia, India and Pakistan have experienced five consecutive heat waves this year.

This year's high temperature is not only high in summer around the world, but also a feature driven by the Arctic ice sheet, that is, the appearance of hot cover phenomenon.

Hot cover refers to blocking high pressure over a certain area, resulting in a large amount of hot air, which can't get out and is compressed downward by high pressure, causing the temperature of the whole continent to soar for days to weeks. In July, 20021year, this situation has already appeared in the United States and Canada in North America.

According to the theory of meteorological research, the Arctic is one of the freezers or ice towers in the world. The high temperature in the Arctic slows down the high-speed airflow and increases the possibility of hot cover phenomenon. Of course, Arctic and global warming are attributed to global climate change.

Although there are many reasons for global climate change, including the natural cycle of the earth, sunspot activity and so on. We can't rule out the causes of human activities, such as greenhouse gas emissions caused by the use of fuels such as coal, oil and natural gas, which trap hot air in the atmosphere.

The United Nations Intergovernmental Panel on Climate Change (IPCC) pointed out that greenhouse gases pushed the concentration of carbon dioxide in the atmosphere to the highest point in 2 million years. Both the IPCC assessment report and the World Meteorological Organization's global climate report 202 1 show that the past seven years have been the hottest on record.

Data show that in 20021year, the concentration of greenhouse gases in the atmosphere is still rising, and human consumption of fossil fuels is undoubtedly the chief culprit of global warming.
