The American Geophysical Union, (AGU) is a world-wide scientific community for the advancement and research of Earth and Space as applied to human beings. AGU is a technical society with approximately 50,000 members comprised of scientists, teachers and students. AGU conducts conferences, meetings, publishes journals, books and weekly newsletters on geophysics and related subject matter. AGU sponsors education programs and provides on-line public access to a great deal of its work. AGU sponsors public outreach to the media for the purposes of improving science-related writing to the general public.
Mercury's movements give scientists peek inside the planet
The first measurements of Mercury's movements from a spacecraft orbiting the planet reveal new insights about the makeup of the solar system's innermost world and its interactions with other planetary bodies.
'Carbon sink' detected underneath world's deserts
The world's deserts may be storing some of the climate-changing carbon dioxide emitted by human activities, a new study suggests. Massive aquifers underneath deserts could hold more carbon than all the plants on land, according ...
Melting glaciers feed Antarctic food chain
Nutrient-rich water from melting Antarctic glaciers nourishes the ocean food chain, creating feeding "hot spots" in large gaps in the sea ice, according to a new study.
New study favors cold, icy early Mars
The high seas of Mars may never have existed, according to a new study that looks at two opposite climate scenarios of early Mars and suggests that a cold and icy planet billions of years ago better explains water drainage ...
Alaska glaciers make large contributions to global sea level rise
Alaska's melting glaciers are adding enough water to the Earth's oceans to cover the state of Alaska with a 1-foot thick layer of water every seven years, a new study shows.
Little-known quake, tsunami hazards lurk offshore of Southern California
While their attention may be inland on the San Andreas Fault, residents of coastal Southern California could be surprised by very large earthquakes - and even tsunamis - from several major faults that lie offshore, a new ...
Sun's activity controls Greenland temperatures
The sun's activity could be affecting a key ocean circulation mechanism that plays an important role in regulating Greenland's climate, according to a new study. The phenomenon could be partially responsible for cool temperatures ...
The ebb and flow of Greenland's glaciers
In northwestern Greenland, glaciers flow from the main ice sheet to the ocean in see-sawing seasonal patterns. The ice generally flows faster in the summer than in winter, and the ends of glaciers, jutting out into the ocean, ...
Southern Ocean removing carbon dioxide from atmosphere more efficiently
Since 2002, the Southern Ocean has been removing more of the greenhouse gas carbon dioxide from the atmosphere, according to two new studies.
Ethanol refining may release more of some pollutants than previously thought
Ethanol fuel refineries could be releasing much larger amounts of some ozone-forming compounds into the atmosphere than current assessments suggest, according to a new study that found emissions of these chemicals at a major ...
