A study of fossils from the Permian-Triassic extinction event 252 million years ago shows that forests in many parts of the ...

A mass extinction event wiped out around 90% of life. What followed has long puzzled scientists: The planet became lethally ...

The addition of carbon into the ocean could have driven a hotter, more acidic ocean environment. Based on the new timeline, this carbon spike happened just 20,000 years before species started dying.

Now, geologists found the missing key, the amount and type of carbon leading up to these mass extinction events, as measured in the same rock that shows these extinction events, is anomalously high.

River transport of carbon to the ocean is not on a scale that will solve our carbon dioxide problem, but we haven't known how much carbon the world's rivers routinely flush into the ocean, until now.

One theory, the “Strangelove Ocean” theory, argued that for a time after K-Pg, the ocean was essentially dead and the normal carbon cycle just stopped. The problem with the “Strangelove Ocean,” ...

A particular volcanic rock is best for sequestering huge amounts of CO2 deep in the Earth in a way that is stable for geologic time. It reacts with injected CO2 to precipitate new limestone-like rock.

Upon reaching the ocean, ... but new technology—namely the Accelerator Mass Spectrometer—allowed researchers to identify which carbon comes from plants and which carbon comes from rocks. ...

Even so, the ocean is a dynamic, challenging landscape to work in. Scientists are still uncovering new details about how it absorbs and recycles carbon, and any materials they add to seawater are ...

Enhanced rock weathering is a way to accelerate one of the Earth’s natural processes for removing carbon dioxide from the atmosphere. It works like this: Carbon dioxide in the air dissolves into ...
