Heatwave In China: Current Situation And Effects On Farming

Situation created by HEATWAVES:

  • The heatwave threatens China's electricity grid, agricultural output, and livestock.
  • Despite cooler temperatures in some parts of China, specialists across the Yangtze waterway bowl were rushing on Wednesday to limit the damage from the environmental change on power, agribusiness, and dairy cattle.
  • Last Friday marked the beginning of the most prolonged and widespread heatwave in China's history, with about 30 per cent of the 600 meteorological stations along the Yangtze recording their highest notable temperatures ever.

Residents like Zhang Ronghai in Chongqing's southwest reported:

Water and electricity outages due to the mountain fire that raged for four days in the Jiangjin region.

The only logical explanation, as articulated by Zhang, is that

 "They need to go to a power station north of 10 kilometres (6 miles) away" to charge their phones.”

Photos uploaded to Weibo, China's version of Twitter, on Wednesday showed people in Chongqing and Sichuan suffering through and, surprise, calming down during mandated COVID-19 testing.

According to state media, over 5,000 large-scale pig farms in Chongqing have had "difficult challenges" due to the recent weather.

In response, the city's agricultural bureau has developed crisis plans to ensure the animals' safety.

According to research by a professor at Hong Kong's City University,

“Environmental change in China could have dire consequences for farming. The professor predicts that production losses and water shortages "may expand to other food-related sectors, causing a severe cost escalation or food emergency in the worst case."

China's National Meteorological Center lifted its "high alerts" on the country's intensity wave on Wednesday after 12 days.

However, temperatures are still expected to rise beyond 40 degrees Celsius (104 degrees Fahrenheit) in Chongqing, Sichuan, and other Yangtze Valley regions. Temperatures as high as 43.9 degrees Celsius were reportedly recorded by a weather station in Sichuan on Wednesday, as reported by government forecasters on their official Weibo channel.

  • The Chinese government has issued a heat advisory because the country's temperatures are rising at twice the global average rate.
  • China's average ground temperature has risen noticeably faster than the worldwide average over recent years, and it's expected to remain "considerably higher" in the future as environmental change risks increase.
  • China is "a delicate district in worldwide environmental change," according to the most recent yearly environment evaluation released by the Chinese government this week.

 Since 1951, average annual temperature increases in China have averaged 0.26 degrees Celsius (0.47 degrees Fahrenheit), whereas the global average is 0.15 degrees.

 Chinese National Climate Center (NCC), Yuan JiaShuang predicted:

"Later on, the expansion in normal provincial temperatures in China would be a lot higher than the world" at a conference on Wednesday.He warned that China's rapidly shifting environment threatens water supply reliability, environmental adaptability, and agricultural output.

Global Dry Seasons and Forest Fires:

  • Over the past few decades, global dry seasons and forest fires have been triggered by persistent heatwaves, unleashing widespread destruction.
  • Record rainfall has contributed to devastating floods in a few countries.

 U.N. Secretary-General Antonio Guterres warned last month that environmental change leaves "no country safe" and that the globe must choose between "a collective activity or aggregate self-destruction."

  • Temperatures in certain parts of China have recently soared above 44 degrees Celsius (111 degrees Fahrenheit), including Yunnan in the southwest and Hebei in the north.
  •  Based on information from the NCC, 131 weather stations in China have reported temperatures at or above record levels, compared to just 62 for all of 2017.
  • Writing on China's environment in 2021, scientists found that sea levels had reached an all-time high in 2018.

Moreover, the rate of icy retreat accelerated, the amount of dynamic permafrost along the Qinghai-Tibet Highway reached an all-time high, and the amount of ocean ice continued to recede.
