Three critical factors in the end-Permian mass extinction

Two-hundred fifty-two million years ago, volcanic eruptions led to massive climate changes. Around the globe, roughly 75 percent of all land-based organisms and roughly 90 percent of all marine organisms died out as a result. ...

Sediment cores from ocean floor could contain 23-million-year-old climate change clues

Sediment cores taken from the Southern Ocean dating back 23 million years are providing insight into how ancient methane escaping from the seafloor could have led to regional or global climate and environmental changes, according ...

Oceans are better at storing carbon than trees. In a warmer future, ocean carbon sinks could help stabilise our planet

We think of trees and soil as carbon sinks, but the world's oceans hold far larger carbon stocks and are more effective at storing carbon permanently.

Fishing, pollution and rising temperatures: How marine science can help us save the oceans

A healthy sea determines the planet's balance and, in turn, the health and well-being of its people. That is why ocean science has never played a more vital role, helping us to grasp today's deterioration of the world's biggest ...

Sharp decline in reported severity of ocean acidification impacts on fish behaviour

As humans fill the atmosphere with excess carbon dioxide, much of it gets absorbed by the oceans, acidifying them—a potential concern for marine life. According to a new study publishing February 3rd in PLOS Biology, however, ...

Fossil snail shells offer new tool for analyzing ancient ocean chemistry

A collection of fossil shells from marine snails and clams is challenging a theory that says the world's deadliest mass extinction was accompanied by severe ocean acidification.

Accumulated heat in the upper ocean is at record levels again

The world's oceans are hotter than ever before, continuing their record-breaking temperature streak for the sixth straight year. The finding based on the latest data through 2021 comes at the end of the first year of the ...

Study examines the effects of ocean acidification on phytoplankton's energy stores

Ocean acidification—which is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean—is a significant threat to the structure and function of marine life. In a study published in the New Phytologist, ...
