Heatwaves Threatening – Greenpeace Warned

Hot weather is starting sooner in Tokyo, Beijing, and Seoul, according to a study, and more frequent heatwaves are anticipated.

According to research by Greenpeace East Asia, scorching temperatures are becoming considerably more common in cities across East Asia, with the environmental organization warns that the early onset of hot weather might have serious consequences for people’s lives as well as agriculture. Researchers looked examined data from 57 locations throughout mainland China, Korea, and Japan and discovered that hot weather was coming earlier in the year in more than 80% of the places.

It has been seen that several Olympic athletes fall due to heatstroke in the last two weeks. Extreme heat in Guangdong, China, prompted industries to close earlier this summer, and heatwaves in Korea killed hundreds of thousands of animals, according to Greenpeace East Asia climate urgency project manager. Greenpeace claimed the severe heat occurrences were “not a fluke” and were consistent with the region’s changing climate in a statement issued on Thursday. Hazardous temperatures will become more frequent unless governments shift away from polluting fossil fuels and toward greener energy sources like wind and solar. 

Forest fires ravaged Turkey, Greece, and other regions of southern Europe,

engulfing residential areas, and the effects of severe heat were observed everywhere in the world in recent days.

 According to a report released last week, there has been an “exceptional rise” in climate-related disasters, including record-breaking heatwaves and wildfires in Australia and the US. Several climate change tipping points, according to the experts, are now approaching. The most recent Greenpeace research looked at 28 Chinese cities, 21 Japanese cities, and eight Korean cities. For the period 2001-2020, the first hot day of the year, measured at 30oC (86F) or above, occurred sooner in 24 of the 28 Chinese cities analyzed than in the preceding 20 years.

The first hot day in Shanghai came 12 days sooner, while the first hot day in Beijing arrived 4.7 days earlier on average. The first hot day of the year occurred on average 11 days sooner in Tokyo and Seoul between 2001 and 2020 than in the preceding 20 years, according to the research. Meanwhile, the Japanese city of Sapporo moved 23 days forward, making it the earliest of all the cities studied. In South Korea, the city of Gwangju experienced the most substantial shift, with its first hot day arriving 12.7 days earlier than the benchmark over the period 2001-2020.

More Serious and Frequent Heatwaves: Changes in Climate

According to the report, cities across East Asia are suffering increasingly severe and frequent heatwaves. Between 2001 and 2020, the frequency of heatwaves in Beijing, China’s capital, was roughly three times higher than it had been in the preceding 40 years. According to the research, the number of days with a temperature of 33oC (91.4F) or greater in Tokyo, which is known for its summer heat and humidity, has more than quadrupled since the 1960s.

Extreme temperatures and the onset of hot weather early have a negative impact on people’s livelihoods, crops, and the entire environment, according to the research. The elderly, individuals who work outside, and people with chronic health issues are all in danger. Heat-related mortality in adults aged 65 and up climbed by 54% globally between 2000 and 2018, with Japan and eastern China bearing disproportionately high costs. 

According to a second Greenpeace research published in July, 73 of the 98 heat waves in the Guangzhou region of China during the previous 60 years happened after 1998. Greenpeace East Asia is asking governments to take steps to decrease greenhouse gas emissions that contribute to climate change. Authorities must intervene quickly to protect people’s health in the face of catastrophic weather. It is critical to tighten climate objectives, including ending all fossil fuel sector financing and transitioning to 100 percent renewable energy as soon as possible.

The subject of climate change and carbon reduction will be revisited during the COP26 conference in Glasgow, Scotland, in November. The meeting seeks to achieve net-zero global emissions by 2050, as recommended by the Paris Agreement. According to scientists, reducing global emissions to net-zero would protect the planet from reaching a potentially disastrous 1.5°C rise. However, the World Meteorological Organization cautioned in May that over the next five years, the average global temperature will continue to rise approaching the crucial 1.5oC threshold.
