Tim Bartholomaus and Suzanne and Bob Anderson hauled 25 kilograms of equipment over 25 kilometres in 25 hours to get a handle on glacier flow — without breaking the bank.
Using sophisticated multibeam imaging equipment aboard a French Navy vessel, Marc Fournier and colleagues mapped the structure of the enigmatic Owen fracture zone underneath the Arabian Sea.
Crumpling of the crust above a sinking dense mantle layer, which is underneath central Europe, triggered the formation of the eastern Alps and the Carpathian mountains, and its surroundings were stretched to form the Pannonian Basin.
In each of the three main ocean basins, dense water from around Antarctica circulates in the bottom layers, and in the Atlantic ocean, an upper circulation cell that is driven from the north caps the bottom loop.
The Intergovernmental Panel for Climate Change has convinced the public that climate change is real. To tackle it, the panel needs complementary climate services that provide continuous climate information for all regions and the globe.
Thanks to global carbon-cycle feedbacks, the Earth may have escaped global glaciation during the Neoproterozoic era, enabling photosynthesis to continue.
The shift of autumnal colouring of leaves to later in the year is due to high ambient atmospheric carbon dioxide concentrations and is independent of temperature.
Although the climate on Venus is very different from that on Earth, many features of the two planets' atmospheric circulations and their lightning regimes are more similar than we thought.
Both the continued bulldozing by India and the collapse of the thicker parts of the Eurasian plate towards the circum-Asiatic oceanic plates contribute to the ongoing deformation of the Asian continental interior.
By slowing down the rate of river incision, large landslides govern a river's response to climatic or tectonic changes and significantly influence landscape evolution.
Amazonian fires and the associated emissions of smoke particles to the atmosphere have been much lower in 2006 than was expected from previous years, thanks to a successful international agreement.
