Widespread bleaching of reefs is devastating delicate ecosystems

A community-based approach to restoration combined with an ingenious device can bring back reefs traumatized by dynamite fishing.

Switzerland kicked the hornet’s nest of geoengineering with an official proposal to find a way to shade the Earth at the UN Environment Assembly’s latest gathering in Nairobi.

Scientists are investigating reports of dying coral along a 1,100-kilometre stretch from Lizard Island in the north to Heron Island in the south.

We no longer need authors or scientists to imagine it; real-world experience does the trick for anyone who’s paying close attention.

After years of nuclear detonations in the Marshall Islands, fallout and forced relocations of communities began a ripple effect: Many Indigenous Marshallese people who had relied on subsistence farming and fishing for 4,000 years suddenly couldn’t trust the safety of their food, becoming reliant on imported and processed foods. And those were the lucky ones.

Wastewater fuels blooms of reef-smothering algae. Better engineering and an army of funny-looking fish can come to the rescue.

Giant clams suffer similar struggles with warming water, though the consequences don’t seem quite as dire.

Almost two-thirds of sharks and rays living on the world’s coral reefs are at risk, with 14 of 134 species deemed critically endangered.

Seven ways in which our destruction of the natural world has led to deadly outcomes.

The rate of warming in the top two kilometres has doubled from levels in the 1960s, a review finds.

Researchers are working to prove that coral-eating fish spread corals’ symbiotic algae in their feces. If they’re right, it could open new opportunities for helping struggling reefs cope.

We can thank microbes for moving carbon to the depths of the ocean, but will our changing world mess with their good work? And should we intervene?

Portfolio selection rules on evaluating risk used to pick 50 reefs as ‘arks’ best able to survive climate crisis and revive coral elsewhere.

Celebrities joined Prince William in London on Sunday, October 17, 2021, for the inaugural awards ceremony of his Earthshot Prize, an ambitious environmental program that aims to find new ideas and technologies around the world to tackle climate change and Earth's most pressing challenges.
