With the sun scorching many cities early this year, experts said on Tuesday that such a changing climate trend will become more pronounced in the long run. However, this will not become a major problem in ensuring power supply for people’s livelihood.

In the next three days, the temperature in northern China will rapidly exceed 35 degrees Celsius, according to data released by the China Meteorological Administration. High temperatures are expected to peak on Thursday, with Beijing, Tianjin and Hebei seeing consecutive high readings.

Conversely, along the Yangtze River and more southerly areas will experience intermittent rain in the coming days, accompanied by heavy downpours.

As of Monday, more than half of China’s provincial capital cities had experienced their first high temperatures of the year, with most of them arriving earlier than in previous years.

Hangzhou in East China’s Zhejiang Province, Chongqing in Southwest China and Guangzhou in South China’s Guangdong Province saw the first day of high temperatures arrive a month earlier than normal. Analysis of Meteorological Big Data by Weather China found that the arrival of high temperatures in most regions of China is getting earlier and the number of days is increasing.

In China, heat waves and high temperatures usually start in June, Beijing-based meteorologist Zhang Mingying told the Global Times on Tuesday.

According to Zhang, there are two types of heat – dry or muggy. The scorching heat that appears in July and August can have a major impact on people’s lives and health, whether people are indoors or outdoors.

Comparing the average first high temperature day for each decade from 1971 to 2020, Chongqing, Nanjing, Fuzhou and Hangzhou saw significant progress, with Chongqing ahead by more than a month.

According to the National Climate Center, the national temperature in spring 2023 was above average, ranking seventh for the same period in history, but with significant fluctuations.

Precipitation was generally below average, the lowest since 2012 for the same period, with large spatial variations. Precipitation was higher than average in the eastern parts of North and Northwest China, while it was lower in the Southwest, South, and Northeast. A total of 184 National Weather Service stations reached extreme event levels of maximum daily temperature.

The World Meteorological Organization (WMO) reports that as temperatures rise, there is a 98 percent chance that at least one of the next five years will be the hottest on record. The next five years will be the hottest on record. As global warming progresses, the world may see more intense extreme high temperature events, and extreme weather events such as heat waves may become the norm.

With the onset of high temperatures, Guangdong began providing high temperature subsidies to workers in related occupations to be distributed continuously for five months.

Yuanyang County in Xinjiang, central China’s Henan Province, issued a high temperature warning on Tuesday, stating that those working in high temperatures should reduce their continuous work hours.

In eastern China’s Jiangsu province, daily electricity load has already exceeded 100 million kilowatts, earlier than in previous years. In response to the surge in residential electricity consumption, State Grid Jiangsu Electric Co. launched the “Electricity Calendar” function, so that users can intuitively understand the electricity consumption situation and save electricity during peak periods.

Lin Boqiang, research director of the China Center for Energy Economics at Xiamen University, told the Global Times that if the energy usage structure does not change to green energy, such climate change trend will become more and more obvious in the long run.

Although it is uncertain whether this summer’s maximum temperature will be higher than last year’s or whether the days with high temperatures will be longer than in 2023, ensuring the supply of electricity for people’s livelihood will not be a big problem, Lin noted.

In 2023, the first days with high temperatures in India, Vietnam, Singapore and other countries arrived earlier than in previous years, with temperatures in some places even breaking historical records for the same period.

Despite the cooling effect of La Ni events in the past three years, the period from 2015 to 2022 was still the eight warmest years on record, the Global Climate Status Report 2022 released by the WMO points out. Melting glaciers and rising sea levels hit record highs in 2022.
