Major rivers, waterways and reservoirs in China's Guangdong province are threatening to unleash dangerous floods, forcing the government on Sunday to enact emergency response plans to protect more than 127 million people, Reuters reported.
Calling the situation "grim", local weather officials said sections of rivers and tributaries at the Xijiang and Beijiang river basins are hitting peak water levels that only happen once in 50 years, according to state broadcaster CCTV news on Sunday.
Massive flooding is expected at the Beijiang basin, CCTV said quoting China's water resource ministry, prompting it to raise an emergency advisory.
Guangdong officials urged departments in all localities and municipalities to begin emergency planning to avert natural disasters and promptly disperse disaster relief funds and materials to ensure affected people have food, clothing, water and a place to live.
The province has seen torrid downpours and strong winds since Saturday evening due to severe convective weather which has affected several parts of China over the past few weeks, Reuters reported.
A 12-hour stretch of heavy rain, starting from 8 p.m. (1200 GMT) Saturday, battered the central and northern parts of the province in Zhaoqing, Shaoguan, Qingyuan and Jiangmen.
Some power facilities in Zhaoqing were damaged, cutting power to some places.
"Please look at Zhaoqing's Huaiji county, which has become a water town. The elderly and children at the countryside don't know what to do with power outages and no signal," said one user on the popular social media site Weibo.
Raging muddy flood waters swept one vehicle down a narrow street in Zhaoqing, showed a video released by Hongxing News.
"It rained like a waterfall for an hour and a half on the highway driving home last night," said another netizen. "I couldn't see the road at all."
Many hydrological stations in the province are exceeding water levels, weather officials warned, and in the provincial capital Guangzhou, a city of 18 million, reservoirs have reached flood limits, city officials announced on Sunday.
Data showed 2,609 hydrological stations with daily rainfall greater than 50 mm (1.97 inches), accounting for about 59% of all observation stations. At 8 a.m. Sunday, 27 hydrological stations in Guangdong were on alert.
Officials have been reducing water levels at the reservoirs through spillways and culvert discharge to ensure downstream flood control.

Pearls may soon be cultivated in European seas for the first time ever, as Italian oyster farmers seek to exploit an unexpected opportunity offered by the rapidly warming Mediterranean.

In late 2023, the first specimens of Pinctada radiata, a pearl oyster native to the Red Sea, were spotted in the Gulf of Poets, a popular tourist area around 100 kilometers (62 miles) from Genoa on Italy's north-western coast.

Less than a year later, they are proliferating in what have always been some of the Mediterranean's coldest waters, more normally associated with other types of oyster used for food rather than jewellery.

"We are looking into the possibility of producing cultivated pearls here," said Paolo Varrella, the head of a cooperative that has been breeding food oysters in the area since 2011.

The group has already made contact with pearl oyster farmers in Mexico to get tips on production techniques, Varrella said.

"The Pinctada radiata has been reported in the Ionian Sea around the island of Sicily since the 1970s, but only in the last decade has it moved north" to the cooler Tyrrhenian and Ligurian seas that lap the western Italian mainland, said Salvatore Giacobbe, professor of ecology at the University of Messina.

It is the latest in a succession of alien warm-water species to enter the Mediterranean as it heats up due to climate change.

Manuela Falautano, a scientist at the Italian environmental research and protection institute ISPRA, said this trend had seen "an exponential increase" in the last decade.

Some of these species are aggressive and disrupt delicate ecosystems. In a few cases, such the spotted puffer fish and the scorpion fish, they are also dangerous to humans.

The 2.5 million square kilometer (970,000 square mile) expanse of water that separates southern Europe from Africa and the Middle East is heating up faster than the average of the world's seas, Falautano said.

BIG MONEY

Pearl production, more readily associated with Polynesian atolls than the northern Mediterranean, has an annual global turnover of 11 billion dollars, and Italian oyster farmers are keen to cash in.

Adriano Genisi, a pearl importer for more than 30 years, said the Radiata may produce gems similar to Japan's renowned "Akoya" pearls which have a diameter of 5-9 millimeters and a white color with shades of grey, pink and green.

If all goes well the first pearls could be harvested in about a year, he said.

The rising temperature of the Mediterranean is also blamed for an increase in violent storms such as the one that sank the luxury yacht of British tech entrepreneur Mike Lynch off Sicily last month, killing six passengers and the boat's cook.

Franco Reseghetti, a researcher at Italy's National Institute for Geophysics and Vulcanology, said measurements taken in the Tyrrhenian in December at depths of between 300 and 800 meters showed the highest temperatures since 2013, and he expected to see a further increase this year.

"The huge amount of energy behind this heating can act as a fuel for devastating atmospheric phenomena" such as the violent storm which appeared to have sunk the yacht off Sicily, Reseghetti said.
