Evaluating the seismic risk of mineral carbon sequestration

Geologic carbon sequestration, in which carbon is captured and stored underground, has been proposed as one way to mitigate the climatic effects of carbon dioxide emissions. One method of geologic carbon sequestration is ...

Triton: A subsurface ocean?

Neptune's largest moon Triton is most likely a captured Kuiper Belt Object. The capture of icy Triton and the subsequent taming of its orbit likely led to the formation of a subsurface ocean through tidal heating. New research ...

First plants caused ice ages: research

New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. Led by the Universities of Exeter and Oxford, the study is published today (February 1, 2012) in Nature Geoscience.

Exposed rocks point to water on ancient Mars

A new discovery of hydrothermally altered carbonate-bearing rocks on Mars points toward habitable environments deep in the martian crust, a Planetary Science Institute researcher said.

Plants Save the Earth from an Icy Doom (w/ Podcast)

(PhysOrg.com) -- Fifty million years ago, the North and South Poles were ice-free and crocodiles roamed the Arctic. Since then, a long-term decrease in the amount of CO2 in the atmosphere has cooled the Earth. Researchers ...
