warming oceans

The decline of one of the rarest whales in the world appears to be slowing, but scientists warn the giant mammals still face existential threats from warming oceans, ship collisions and entanglement in fishing gear.

Giant waves are becoming more common off California’s coast as the planet warms, according to innovative new research that tracked the surf's increasing height from historical data gathered over the past 90 years.

Earth’s average temperature remained at a record high on Wednesday, July 5, 2023, after two days in which the planet reached unofficial records. It’s the latest marker in a series of climate-change-driven extremes.

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

Higher ocean and river temperatures are stressing Atlantic salmon, depriving these iconic fish of oxygen and forcing them to swim farther to find food. These climate change pressures are also impacting salmon in ocean farms, which have seen an increase in mass die-offs.

The loss will contribute a minimum rise of 27 centimetres regardless of what climate action is taken, scientists say.

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.

Weaker sharks are less effective hunters, which can upset the balance of the ecosystem, say the authors of a study into the impacts of hotter oceans.

World leaders met in France on Monday, August 26, 2019, to discuss some of the most pressing issues of our time: climate change, biodiversity, and warming oceans. The members of the G-7 — the world’s richest nations — walked away from that meeting with a plan to release $20 million in aid to the countries battling historic blazes in the Amazon. But one leader was notably absent: Donald Trump.
