Over millions of years, most living organisms suffocated in oxygen-deprived oceans. In the aftermath, modern vertebrates conquered the world. (Credit: Rich Carey/Shutterstock) We think of mass extinctions as brief moments of havoc — profoundly devastating but over within a geologic instant. The Devonian, the second of the so-called “Big Five,” […]

Volcanism is one of the main carbon dioxide sources in the long-term carbon cycle balanced by weathering sinks, which, among others, represent important processes included in Komar and Zeebe’s model.

Among the report’s case studies: Africa’s Kariba Dam, the world’s largest man-made reservoir, impounding 181 km³ of water. Almost $300 million was loaned in 2014 to repair the dam, with completion expected by 2023. The report says “Dams like Kariba will likely continue to operate much longer with recurring investments […]

Stanford researcher Ryan Searcy collects water samples from a tide pool at the Fitzgerald Marine Reserve, in Moss Beach, California.

In mid-January 2021, the Pacific Northwest of North America was soaked by several episodes of heavy rainfall, leading to widespread flooding and landslides.

It may not be very well known, but the Arctic Ocean leaks enormous amounts of the potent greenhouse gas methane. These leaks have been ongoing for […]

New study unravels long-standing climate mystery and provides insight into how our planet may change in the future. Scientists claim to have found the “missing link” in the process that leads to an ice age on Earth. Melting icebergs in the Antarctic are the key, say the team from Cardiff […]

Credit: Steve Gschmeissner/Science Photo Library A group of international scientists, including an Australian astrophysicist, has used know-how from gravitational-wave astronomy (used to find black holes in space) to study ancient marine fossils as a predictor of climate change. The research, published in the journal Climate of the Past, […]

New technology from Stanford scientists finds long-hidden quakes, and possible clues about how earthquakes evolve. Tiny movements in Earth’s outermost layer may provide a Rosetta Stone for deciphering the physics and warning signs of big quakes. New algorithms that work a little like human vision are now detecting these long-hidden […]
