Researchers at the California Institute of Technology (Caltech) and their colleagues have found evidence of ancient climate change on Mars caused by regular variation in the planet's tilt, or obliquity. On Earth, similar "astronomical forcing" of climate drives ice-age cycles.

It won't help the Titanic, but a newly derived, simple law may help scientists improve their climate models and glaciologists predict where icebergs will calve off from their parent ice sheets, according to a team of Penn State researchers.

New "petascale" computer models depicting detailed climate dynamics, and building the foundation for the next generation of complex climate models, are in the offing.

The development of powerful supercomputers capable of analyzing decades of data in the blink of an eye mark a technological milestone capable of bringing comprehensive changes to science, medicine, engineering, and business worldwide.

Using a remotely operated submersible vehicle the international research team captured images of life found on deep-sea pinnacles and valleys up to three kilometres beneath the Ocean’s surface.

Wind isn't acting alone in the geological process behind erosion, sand dunes and airborne dust particles called aerosols. The other culprit is electricity.

The International Ice Charting Working Group predicts more marine transportation in the Arctic as sea ice continues to diminish and warns of "significant hazards to navigation," according to a statement released yesterday.

IBM (NYSE: IBM) and the Climate Systems Analysis Group at the University of Cape Town are launching a global computing effort to improve regional climate models in order to make better projections about what effects a changing climate will have in Africa.

Not all areas of the Tibetan Plateau rose at the same time, according to researchers who are determining the past elevation of plateau locations by studying the remains of terrestrial plants that once grew there.

Ancient Greenland was green. New Danish research has shown that it was covered in conifer forest and, like southern Sweden today, had a relatively mild climate. Eske Willerslev, a professor at Copenhagen University, has analysed the world’s oldest DNA, preserved under the kilometre-thick icecap.

Climate models are reliable tools that help researchers better understand the observed record of ocean warming and variability.

Using an ocean of data, sophisticated mathematical models and supercomputing resources, researchers at the Department of Energy's Oak Ridge National Laboratory are putting climate models to the test with particular focus on weather extremes.
