The NORINDIA project sheds light on how climate change could affect monsoons, droughts, and glaciers in northern India.
The American Geophysical Union held a public lecture to introduce a new book about how microbes changed the world.

In the last few days another belt of exceptional rainfall has swept across northern Pakistan, including Kohistan, triggering large numbers of landslides as well as avalanches and floods. The most destructive incident appears to have occurred at Othar Nala village in Kandia, Kohistan district, where a large landslide destroyed a number of houses.
The Greenland ice sheet is the second largest ice body in the world. New research shows that erosion by summertime melt-driven streams on the ice sheet shapes landscapes similarly to, but much faster, than do rivers on land.
Earth's climate, mantle, and core interact over geologic timescales. Climate influences whether plate tectonics can take place on a planet, with cool climates being favorable for plate tectonics because they enhance stresses in the lithosphere, suppress plate boundary annealing, and promote hydration and weakening of the lithosphere. Plate tectonics plays a vital role in the long-term carbon cycle, which helps to maintain a temperate climate. Plate tectonics provides long-term cooling of the core, which is vital for generating a magnetic field, and the magnetic field is capable of shielding atmospheric volatiles from the solar wind. Coupling between climate, mantle, and core can potentially explain the divergent evolution of Earth and Venus.
The Himalayan orogen represents a 'Composite Orogenic System' in which channel flow, wedge extrusion and thrust stacking operate in separate 'Orogenic Domains' with distinct rheologies and crustal positions. We analyze 104 samples from the metamorphic core (Greater Himalayan Sequence, GHS) and bounding units of the Annapurna-Dhaulagiri Himalaya, central Nepal.
WASHINGTON, DC — New research has found that wind carved massive mounds of more than a mile high on Mars over billions of years. Their location helps pin down when water on the Red Planet dried up during a global climate change event.
