Record May heat scorches north, central China
China has endured spates of extreme weather events, from searing heat and drought to downpours and floods, for several summers running.
The country is the world's largest greenhouse gas emitter, but also a renewable energy powerhouse seeking to cut carbon dioxide emissions to net zero by 2060.
State broadcaster CCTV said Tuesday that multiple cities logged all-time May highs this week.
They included Zhengzhou, a metropolis of 13 million people in central Henan province, which saw a high of 41C on Monday, CCTV said.
In nearby Linzhou, temperatures rose to 43.2C, while the small city of Shahe in northern Hebei province logged 42.9C, the national weather office said in a social media post on Monday.
As of 4:00 pm on Monday, 99 weather stations nationwide had matched or exceeded previous temperature records for May, the weather office said.
"(It's so hot) in Zhengzhou that I'm covered in sweat just from cycling for 10 minutes in a skirt and sun-protective top," one user wrote on the Weibo social media platform.
"Any chance you could send a few degrees up to the northeast? It's still freezing here," quipped another.
The weather office said the extreme heat was set to dissipate by Friday, adding that some areas would see rapid drops of up to 15C.
It urged people to "add extra layers of clothing in a timely way as the weather changes, (to avoid) catching a cold".
Last year, dozens of people were killed and thousands evacuated during storms across China that caused severe flooding.
China is the biggest global producer of the greenhouse gases scientists say drive climate change and make extreme weather more frequent and intense.
Beijing aims to bring carbon emissions to a peak this decade ahead of sharp cuts through to 2060, and has dramatically ramped up wind and solar energy installations in recent years as it seeks to wean its huge economy off highly polluting coal.
Emissions peaking?
China's emissions fell in the first quarter of 2025 despite rapidly growing power demand, analysis published last week showed, seen as a key milestone in the country's decarbonisation push.
New wind, solar and nuclear capacity meant CO2 emissions fell by 1.6 percent year-on-year in the first quarter, and one percent in the 12 months to March, said analyst Lauri Myllyvirta at the Finland-based Centre for Research on Energy and Clean Air (CREA).
Last month, China's national energy body said wind and solar energy capacity had surpassed that of mostly coal-powered thermal for the first time.
It added that wind and solar additions had "far exceeded" the total increase in electricity consumption, a trend that experts said may mean carbon emissions from the power sector are on the verge of peaking.
Despite the renewable energy boom, China also began construction on 94.5 gigawatts of coal power projects in 2024, 93 percent of the global total, according to a February report from CREA and the US-based Global Energy Monitor (GEM).

Swiss glacier collapse underscores urgency of efficient warning systems elsewhere, experts say
The collapse of the Swiss Birch glacier serves as a chilling warning of the escalating dangers faced by communities worldwide living under the shadow of fragile ice, particularly in Asia, experts say. Footage of the May 28 collapse showed a huge cloud of ice and rubble hurtling down the mountainside, into the hamlet of Blatten. Ali Neumann, disaster risk reduction advisor to the Swiss Development Cooperation, noted that while the role of climate change in the specific case of Blatten 'still needs to be investigated', the wider impacts were clear on the cryosphere – the part of the world covered by frozen water. 'Climate change and its impact on the cryosphere will have growing repercussions on human societies that live near glaciers, near the cryosphere, and depend on glaciers somehow and live with them,' he said. The barrage largely destroyed Blatten, but the evacuation of its 300 residents last week averted mass casualties, although one person remains missing. 'It also showed that with the right skills and observation and management of an emergency, you can significantly reduce the magnitude of this type of disaster,' Neumann said at an international UN-backed glacier conference in Tajikistan. Stefan Uhlenbrook, Director for Hydrology, Water and Cryosphere at the World Meteorological Organisation (WMO), said it showed the need for vulnerable regions like the Himalayas and other parts of Asia to prepare. 'From monitoring, to data sharing, to numerical simulation models, to hazard assessment and to communicating that, the whole chain needs to be strengthened,' Uhlenbrook said. 'But in many Asian countries, this is weak, the data is not sufficiently connected.' Need better warning systems Swiss geologists use various methods, including sensors and satellite images, to monitor their glaciers. Asia was the world's most disaster-hit region from climate and weather hazards in 2023, the United Nations said last year, with floods and storms the chief cause of casualties and economic losses. But many Asian nations, particularly in the Himalayas, lack the resources to monitor their vast glaciers to the same degree as the Swiss. According to a 2024 UN Office for Disaster Risk Reduction report, two-thirds of countries in the Asia and Pacific region have early warning systems. But the least developed countries, many of whom are in the frontlines of climate change, have the worst coverage. 'Monitoring is not absent, but it is not enough,' said geologist Sudan Bikash Maharjan of the Nepal-based International Centre for Integrated Mountain Development (ICIMOD). 'Our terrains and climatic conditions are challenging, but also we lack that level of resources for intensive data generation.' That gap is reflected in the number of disaster-related fatalities for each event. While the average number of fatalities per disaster was 189 globally, in Asia and the Pacific it was much higher at 338, according to the Belgium-based Centre for Research on the Epidemiology of Disasters' Emergency Events Database. Heightened risk of landslides Himalayan glaciers, providing critical water to nearly two billion people, are melting faster than ever before due to climate change, exposing communities to unpredictable and costly disasters, scientists warn. Hundreds of lakes formed from glacial meltwater have appeared in recent decades. They can be deadly when they burst and rush down the valley. The softening of permafrost increases the chances of landslides. Declan Magee, from the Asian Development Bank's Climate Change and Sustainable Development Department, said that monitoring and early warnings alone are not enough. 'We have to think ... about where we build, where people build infrastructure and homes, and how we can decrease their vulnerability if it is exposed,' he said. Nepali climate activist and filmmaker Tashi Lhazom described how the village of Til, near to her home, was devastated by a landslide earlier in May. The 21 families escaped – but only just.

"These are complex disasters, working together with the communities is actually just as, if not much more, important," he said.
