Deep-sea mining could have a “catastrophic” impact in the Pacific, Palauan President Surangel Whipps Jr said, as companies forge ahead with plans to suck up millions of tonnes of seabed in the hunt for valuable metals.
Mining companies want to scrape vast sections of the Pacific Ocean for metals such as nickel and cobalt — used in electric car batteries — and are planning to ramp up full scale operations from 2024.
Conservation groups and scientists fear this could devastate poorly understood marine systems that play a crucial role in regulating the climate.

Whipps Jr said deep-sea mining should not go ahead until more was known about its consequences.
“Please put a moratorium on it,” he said. “We are your partners in the Pacific, and we share this ocean, and we must make sure that what we do doesn’t contribute to our islands sinking.”
Palau is an archipelago of about 340 islands east of the Philippines, and is extremely vulnerable to rising seas.
The country joined forces with Fiji and Samoa earlier this year to push for a 10-year ban on deep-sea mining until the environmental consequences were better understood.
“Can we slow down, take a stocktake of where we are, and really do our part to do the proper research before we do something that could be catastrophic to our oceans,” Whipps Jr said.
Marine biologists from the University of California, Santa Barbara summarized the risks in a paper published by the World Economic Forum this year.
“The sheer importance of the ocean to our planet and people, and the risk of large-scale and permanent loss of biodiversity ... necessitate a pause of all efforts to begin mining of the deep sea,” it said.
On the other side of the debate sit low-lying Pacific nations Nauru, Tonga, Kiribati and the Cook Islands, which see deep-sea mining as a potentially lucrative income stream as climate change disrupts other industries.
Canadian mining start-up The Metals Company is leading the push to mine in the Pacific Ocean’s Clarion Clipperton Zone, a sweeping expanse of seafloor more than twice the size of Alaska.
Last month it announced the completion of “historic deep-sea trials” by its subsidiary in Nauru.
Joey Tau, who works with conservation group Pacific Blue Line, said the region should not be used as a testing ground.
“For the Pacific, it’s come from a history that we’ve seen this part of the world go through waves of tests — it reminds us of nuclear testing back then,” Tau said.
Nearly half of China’s major cities are suffering “moderate to severe” levels of subsidence, putting millions of people at risk of flooding, especially as sea levels rise, according to a study of nationwide satellite data released yesterday. The authors of the paper, published by the journal Science, found that 45 percent of China’s urban land was sinking faster than 3mm per year, with 16 percent at more than 10mm per year, driven not only by declining water tables, but also the sheer weight of the built environment. With China’s urban population already in excess of 900 million people, “even a small portion
UNSETTLING IMAGES: The scene took place in front of TV crews covering the Trump trial, with a CNN anchor calling it an ‘emotional and unbelievably disturbing moment’ A man who doused himself in an accelerant and set himself on fire outside the courthouse where former US president Donald Trump is on trial has died, police said yesterday. The New York City Police Department (NYPD) said the man was declared dead by staff at an area hospital. The man was in Collect Pond Park at about 1:30pm on Friday when he took out pamphlets espousing conspiracy theories, tossed them around, then doused himself in an accelerant and set himself on fire, officials and witnesses said. A large number of police officers were nearby when it happened. Some officers and bystanders rushed
HYPOCRISY? The Chinese Ministry of Foreign Affairs yesterday asked whether Biden was talking about China or the US when he used the word ‘xenophobic’ US President Joe Biden on Wednesday called for a hike in steel tariffs on China, accusing Beijing of cheating as he spoke at a campaign event in Pennsylvania. Biden accused China of xenophobia, too, in a speech to union members in Pittsburgh. “They’re not competing, they’re cheating. They’re cheating and we’ve seen the damage here in America,” Biden said. Chinese steel companies “don’t need to worry about making a profit because the Chinese government is subsidizing them so heavily,” he said. Biden said he had called for the US Trade Representative to triple the tariff rates for Chinese steel and aluminum if Beijing was
Beijing is continuing to commit genocide and crimes against humanity against Uyghurs and other Muslim minorities in its western Xinjiang province, U.S. Secretary of State Antony Blinken said in a report published on Monday, ahead of his planned visit to China this week. The State Department’s annual human rights report, which documents abuses recorded all over the world during the previous calendar year, repeated language from previous years on the treatment of Muslims in Xinjiang, but the publication raises the issue ahead of delicate talks, including on the war in Ukraine and global trade, between the top U.S. diplomat and Chinese
