Climate Change Is Devastating Coral Reefs Worldwide, Major Report Says

The New York Times

October 4, 2021
The world lost about 14 percent of its coral reefs in the decade after 2009, mainly because of climate change, according to a sweeping international report on the state of the world’s corals.

The report, issued late Monday, underscores the catastrophic consequences of global warming while also offering some hope that some coral reefs can be saved if humans move quickly to rein in greenhouse gases.

“Coral reefs are the canary in the coal mine telling us how quickly it can go wrong,” said David Obura, one of the report’s editors and chairman of the coral specialist group for the International Union for Conservation of Nature.

The 14 percent decline, he said, was cause for deep concern. “In finance, we worry about half-percent declines and half-percent changes in employment and interest rates.”

Great Barrier Reef suffers third mass bleaching event in five years

Australia's Great Barrier Reef has experienced its most widespread bleaching event on record, with the south of the reef bleaching extensively for the first time, a new survey has found.

This marks the third mass bleaching event on the reef in just the last five years and scientists say that the rapid warming of the planet due to human emissions of heat-trapping gases are to blame.

Aerial analysis conducted by Terry Hughes, director of the ARC Center of Excellence for Coral Reef Studies at James Cook University, and others from the Great Barrier Reef Marine Park Authority, found that coastal reefs along the entire length of the iconic reef -- a stretch of about 1,500 miles (2,300 kilometers) from the Torres Strait in the north, right down to the reef's southern boundary -- have been severely bleached.

Reef-building coral exhibiting 'disaster traits' akin to the last major extinction event

A study published Tuesday in Scientific Reports shows that stony corals, which provide food and shelter for almost a quarter of all ocean species, are preparing for a major extinction event.

The research team—which includes scientists from The Graduate Center, CUNY; Baruch College; Scripps Institution of Oceanography; University of Haifa; University of Leeds; and GEOMAR Helmholtz Centre for Ocean Research—found that corals are currently exhibiting a suite of dynamic survival responses that correspond with their last major extinction 66 million years ago.

Earth's coral reefs could be gone by 2100, research finds

NBC News

February 18, 2020
Climate change could wipe out almost all coral reef habitats around the world by 2100, according to research released Monday.

The bleak outlook forecasts that warming oceans and rising seas could have a devastating impact on ocean ecosystems, suggesting that efforts to restore dying corals will likely encounter difficulties as global warming continues to wipe out habitats that could once support healthy reef systems.
