Shanghai says water supplies ‘normal’ after shortage scare sparks hoarding

A wave of panic buying has swept Shanghai in recent days, as rumours swirled of drinking water shortages despite assurances from local authorities that supplies remained normal. Record-breaking droughts in China dried up parts of the Yangtze River, and prompted saltwater intrusions into the estuary and depleted reservoirs feeding Shanghai, which sits at the mouth of the crucial river. Caixin media reported on Tuesday that Shanghai authorities had taken emergency measures to secure water supply after the intrusions contaminated two of Shanghai’s four primary reservoirs and forced their temporary closure.…

China reports ‘most severe’ heatwave and third driest summer on record

China recorded its highest temperatures and one of its lowest levels of rainfall in 61 years during a two-month summer heatwave that caused forest fires, damaged crops and hit power supplies, the national meteorological agency said. The average national temperature in August, 22.4C, was 1.2C higher than the seasonal norm, while average rainfall fell 23% to 82mm, the third lowest since records began in 1961, according to Xiao Chan, the vice-director of China’s national meteorological administration. He told reporters that 267 weather stations across China recorded their highest temperatures in…

‘It’s getting extremely hard’: climate crisis forces China to ration electricity

There were still some streetlights on the Bund, one of the main roads in central Shanghai. But the decorative lights which light up the city skyline – blue, pink, and red – were turned off for two days to cope with the peaking power demand. The power restriction imposed by the city authorities, was the first in Shanghai, the financial hub of China. But across the rest of the country similar restrictions have been put in place, as cities, notably in the south-western region, grapple with ongoing power shortages caused…

China’s Record Drought is Drying Rivers and Feeding Its Coal Habit

HONG KONG — Car assembly plants and electronics factories in southwestern China have closed for lack of power. Owners of electric cars are waiting overnight at charging stations to recharge their vehicles. Rivers are so low there that ships can no longer carry supplies. A record-setting drought and an 11-week heat wave are causing broad disruption in a region that depends on dams for more than three-quarters of its electricity generation. The factory shutdowns and logistical delays are hindering China’s efforts to revive its economy as the country’s leader, Xi…

China issues alert as drought and heatwave put crops at risk

A drought in China is threatening food production, prompting the government to order local authorities to take all available measures to ensure crops survive the hottest summer on record. On Tuesday, four government departments issued an urgent joint emergency notice, warning that the autumn harvest was under “severe threat”. It urged local authorities to ensure “every unit of water … be used carefully”, and called for methods included staggered irrigation, the diversion of new water sources, and cloud seeding. A record-breaking heatwave combined with a months-long drought during the usual…

China drought causes Yangtze to dry up, sparking shortage of hydropower

A record-breaking drought has caused some rivers in China – including parts of the Yangtze – to dry up, affecting hydropower, halting shipping, and forcing major companies to suspend operations. A nationwide drought alert was issued on Friday as a long-running and severe heatwave in China’s heavily populated south-west was forecast to continue well into September. The loss of water flow to China’s extensive hydropower system has sparked a “grave situation” in Sichuan, which gets more than 80% of its energy from hydropower. On Sunday the provincial government declared it…

Weather tracker: deadly floods in South Korea and drought in China

Extreme flooding in South Korea this week submerged streets, cars and buildings, as torrential downpours brought more than a month’s worth of rainfall in the space of a few days. Between Monday and Wednesday a cumulative total of 525mm – a little over 20 inches – was recorded in Seoul. At least nine people are confirmed to have died from the floods and many more are reported injured or missing. High rainfall rates and flooding during the monsoon season in South Korea is common, with average rainfall of up to…

Turning Cities Into Sponges to Save Lives and Property

Imagine a sponge. Swipe it over a wet surface and it will draw up water; squeeze it and the water will trickle out. Now imagine a city made of sponges, or spongelike surfaces, able to soak up rainwater, overflowing rivers or ocean storm surges and release stored water during droughts. Engineers, architects, urban planners and officials around the world are seeking ways to retrofit or reconstruct cities to better deal with water — basically, to act more like sponges. While water management has always been an essential service in cities,…
