A survey showed that 91 percent of the reef experienced bleaching despite this year’s cooler, wetter conditions associated with the La Niña weather pattern.

Researchers use proxy indicators to confirm long-term changes to the Atlantic Meridional Overturning Circulation, which have profound implications for future climate in North America and Europe.

This year’s most captivating illustrations tell stories from the micro scale—such as newborn neurons in the adult brain and bacteria in the infant gut—to the scale of entire ecosystems, including reintroduced predators and rising seas.

Knock-on effects of melting sea ice in the Arctic may be to blame for a spate of gray whale deaths along their migration route from Mexico to Alaska.

For the past two years, the charismatic marine mammals have washed up on Pacific shores in record numbers. Scientists investigating the strandings suspect warming waters and melting sea ice are partly to blame.

Marine ecologist Jeroen Ingels discusses what is known about ice shelf loss at the southern pole and how those changes are affecting local ecosystems.

The movements of water within the ocean basins has been increasing in speed over the last 20 years, a new study shows, conflicting with prior models of climate change.

Some corals can adjust to a range of temperatures, but this ability may be limited in a consistently warmer environment.

Microbes that dwell in nutrient-poor waters use a photopigment called retinal to harvest energy from sunshine at levels at least equal to those stored by chlorophyll-based systems.

Bleaching killed 34 percent of the island’s reefs between 2013 and 2017, a study finds.

The marine scientist was renowned for his passion for exploring waves, marine life, and the way Earth’s largest bodies of water affect the planet’s climate.

As sea temperatures rise, mammals and birds may lose their edge over the cold-blooded species they eat, as well as the sharks that hunt them.

Simulations of Earth’s climate 252 million years ago reveal that the same symptoms of modern climate change likely account for the time period’s extensive loss of marine life.

Gates was director of the Hawaii Institute of Marine Biology and a strong advocate for coral conservation.

The reef has bounced back from “death events” in the past, but that doesn’t mean it will be resilient over the next few decades.

A study of 686 fish and invertebrates predicts that some animals will have to shift more than 1,000 kilometers to stay within tolerable temperatures.

Climate change is bleaching sea anemones, and it’s stressing out the clownfish that live in them.

Aerial survey results reveal severe coral bleaching across much of the massive reef system.

Once again, climate change is killing off masses of coral in Australia’s expansive reef system.
