Why is the temperature getting hotter and hotter in recent two years? Will it get hotter every year in the future?

Why is the temperature getting higher and higher in recent two years? Many friends are curious about why the temperature has become hotter and hotter in the past two years. According to previous data, the concentration of greenhouse gases has been increasing, and the sea level is also rising. Then the change of global climate will naturally affect our country, so from the current situation, the future summer is likely to get hotter year by year.

Will it get hotter every year in the future? If we only look at this year, the high temperature this summer is due to the summer high pressure on the east and west sides of our country. It has amazing performance in explosive power and endurance. The Iranian high pressure in the west is extremely strong, spreading eastward to the northwest of China and merging with the continental high pressure, making the northern region under strong and stable warm high pressure and continuous high temperature.

At 8: 500hPa on July 26th, Beijing time, three high pressures have been turned on/Central Meteorological Observatory In addition, the westerly airflow sinks and heats up at the foot of Taihang Mountain, which has become the driving force of extreme high temperatures in Henan and Hebei. According to the statistics of China Meteorological Bureau, in June 2022, the national temperature was 0.9℃ higher than the same period of last year, the highest since 196 1 year.

But have you noticed that we seem to say "this summer is hotter than before" every year?

The unusually high temperature you think is actually a foreshadowing. ? From 195 1 to 2020, the average annual increase rate of surface temperature in China will reach 0.26℃/ 10 year, which is significantly higher than the global level in the same period. Especially in the last 20 years, it is the warmest period since the beginning of the 20th century. The hottest 10 year in China since 190 1 9 years occurred in the 20th century.

China became a "warm-up" because China is vast. The heating rate of land is higher than that of ocean, and the land area is large, which provides important conditions for the significant increase of regional temperature. Among the top three countries with the largest land area, the latitude of China is generally lower than that of Russian and Canadian, which means that China has the opportunity to get more heat.

Thanks to the double blessing of the two, China's warming rate far exceeds the global average. In addition, as the largest developing country in the world, China is in the heyday of urbanization, and the massive emission of greenhouse gases such as carbon dioxide and the urban heat island effect have also become the driving force of climate warming. However, it is undeniable that the general trend of global warming is behind the rising temperature in China.

Although scientists have attributed the high temperature process to specific "abnormal atmospheric conditions" again and again, it is certain that the global climate change makes the regional atmosphere suddenly change and adjust, which leads to extreme high temperature. In 2020, the global average temperature will be 1.2℃ higher than the pre-industrial level. From 20 1 1 to 2020, this is the hottest decade since 1850.

If global warming rises by 2℃ in the next 20 years or so, the heat wave that should be once in a thousand years may appear every 5 to 10 years.
