Recently, the World Meteorological Organization confirmed that 2023 will be the hottest year in the 174-year observation record. The head of the organization's climate monitoring said at a press conference that 2024 is "extremely likely" to set a new record. High temperature record.
In recent years, news about "the hottest" has been constantly appearing. Is it really getting hotter every year?
The national average temperature in 2023 is the highest in history
13 provinces (autonomous regions and municipalities) simultaneously set "new highs"
Let's first take a look at the national situation.
Previously, the National Climate Center of the China Meteorological Administration completed and released the 2023 China Climate Bulletin. It is mentioned that in 2023, the national average temperature will be 10.7°C, the highest in history since 1951.
In 2023, the temperatures in 31 provinces (autonomous regions and municipalities) across the country were all relatively high. Among them, Shandong, Liaoning, Xinjiang, Guizhou, Yunnan, Tianjin, Hunan, Hebei, Sichuan, Beijing, Henan, Inner Mongolia, and Guangxi were the highest in history since 1961. Zhejiang, Ningxia, Jiangxi, and Hubei have the second highest historical rates.
Not only is the average temperature high, but there are also many high temperatures. In 2023, the national average number of high temperature days was 13.5 days, 4.4 days more than normal, the second most since 1961, and only less than 2022.
The rise in temperature has caused spring and summer to start earlier and autumn and winter to start later in most parts of the country.
In the past 63 years
Sichuan’s average temperature has increased by 0.19℃ every 10 years
Let’s take a look around us.
In 2023, the average temperature in Sichuan Province was 16.1°C, 0.9°C higher than normal, breaking the record of 15.9°C set in 2022 and setting a record high since 1961.
According to data from the Sichuan Provincial Climate Center, between 1961 and 2023, the annual average temperature, annual average maximum temperature, and annual average minimum temperature in Sichuan Province all showed a clear upward trend, with the warming rates of 0.19℃/10a, 0.26℃/10a, and 0.24℃/10a. In other words, Sichuan's annual average temperature will increase by 0.19°C every 10 years. The maximum temperature rise is more obvious, with the annual average maximum temperature increasing by 0.26°C every 10 years.
Specifically, the average maximum temperature in spring rises fastest. At the same time, the average minimum temperature in winter in the western Sichuan Plateau also rises rapidly, increasing by 0.43°C every 10 years. The average surface temperature across the province has increased significantly, with consistent warming in all regions. In addition, high temperature events increased and low temperature events decreased.
This El Niño will end in April
Most of the spring temperatures in my country are close to normal or higher than normal
When the World Meteorological Organization issued a red alert, warning that 2024 may be hotter, "El Niño" was also mentioned.
The El Niño event that started in May 2023 reached its peak in December 2023. This was a moderately intense El Niño event.
According to monitoring, since January 2024, this El Niño event has begun to weaken. The National Climate Center predicts that the El Niño event will end around April 2024.
El Niño is a naturally occurring ocean phenomenon associated with the "warm water phenomenon" of warming ocean surface temperatures in the central and eastern tropical Pacific.
An El Niño event of moderate or above intensity can usually increase the annual average global surface temperature by about 0.1 to 0.22°C. In recent decades, more than 95% of the world's warmest records occurred in El Niño years or the year following El Niño.
According to the National Climate Center's predictions, this spring, except for the northern Northeast, northeastern Inner Mongolia, and northern Xinjiang, the temperatures will be close to normal to relatively high in most other areas of my country. Among them, southwestern Shaanxi, southern Gansu, and Qinghai The temperature in the south, Yunnan, most of Guizhou, Sichuan, most of Chongqing, central and eastern Tibet, etc. is 1-2℃ higher.
