South Korean investigators arrest President Yoon in insurrection probe

SYDNEY: Alarming levels of coral bleaching have been recorded off Australia’s western coast, scientists said Wednesday, turning huge chunks of a celebrated reef system a sickly dull white.

A months-long marine heatwave had “cooked” the sprawling Ningaloo Reef, ocean scientist Kate Quigley said, part of a world heritage-listed marine park renowned for vibrant corals and migrating whale sharks.

Although environment officials were still verifying the scale of damage, Quigley said it was on track to be the region’s worst mass-bleaching event in years.

“Warm oceans have just cooked the corals this year,” Quigley said.

“It wouldn’t be amiss to throw in the word ‘unprecedented.’

“It has gone deep, it’s not just the top of the reef that is bleaching. Many different species of coral are bleaching.”

Branching through shallow waters along Australia’s western coast, the 300-km Ningaloo Reef is one of the largest “fringing reefs” in the world.

The unfolding mass bleaching looked to be the worst since 2011, Quigley said.

Ocean waters lapping Western Australia have been as much as 3 degrees warmer than average over recent summer months, according to the government weather bureau.

Rising temperatures shot past the “bleaching threshold” sometime in mid-January, according to monitoring by the US National Oceanic and Atmospheric Administration.

Bleaching occurs when warm waters trigger a biological response forcing coral to expel the colorful algae embedded in their tissues.

“Bleaching is a sickness, but it does not mean outright death,” said Quigley, a research scientist with environmental charity the Minderoo Foundation.

“But if it is bad enough, the corals will die.”

Government data showed smaller patches of coral bleaching had also been spotted at the northern tip of the more famous Great Barrier Reef on Australia’s east coast.

Quigley said the Ningaloo Reef and the Great Barrier Reef were shaped by different weather patterns — and it was rare to see bleaching on both at the same time.

“What we’re seeing is the level of ocean warming is so great, it’s overriding the local conditions in some places. “It’s just shocking. When we take a national snapshot it’s extremely concerning.”

The Great Barrier Reef, a popular tourist drawcard, has suffered five mass bleachings over the past eight years.

Quigley said the extent of damage on the Great Barrier Reef was not currently widespread enough to be considered “mass bleaching.”

Global average temperatures were the hottest on record in 2024, with prolonged heat waves in many of the planet’s oceans causing particular alarm.

Australia sits on bulging deposits of coal, gas, metals and minerals, with mining and fossil fuels stoking decades of near-unbroken economic growth.

But it is increasingly suffering from more intense heat waves, bushfires and drought, which scientists have linked to climate change.

KINGSTON, Jamaica: Secretary of State Marco Rubio said Wednesday the United States will examine Russia’s requested conditions for agreements with Ukraine, but cautioned that a peace deal would take time.
“It won’t be simple. It’ll take some time, but at least we’re on that road and we’re talking about these things,” Rubio told a news conference in Jamaica.
Russia and Ukraine agreed in parallel separate talks with US envoys in Saudi Arabia to halt strikes in the Black Sea, as President Donald Trump pushes for an end to the war.
The Kremlin said Wednesday that a revival of a deal on Black Sea shipping was subject to “a number of conditions” and that Russia was discussing sanctions relief from the United States.
“We’re going to evaluate that. Some of those conditions include sanctions that are not ours. They belong to the European Union,” Rubio said.
He said that the US negotiators would meet and “then we’ll present that to the president, who will ultimately make a decision about what the next step” is.
“I think it’s a good thing that we have both the Ukrainians and the Russians talking about ceasefires, be they energy or be they potentially in the Black Sea,” Rubio said.
Rubio had earlier called on Russia to accept without preconditions a proposed 30-day general ceasefire agreed by Ukraine.
French President Emmanuel Macron, meanwhile, renewed the call on Russia to accept without conditions and said it was “much too early” to consider lifting sanctions.
