Climate Cooling Trend Over Past 2,000 Years
Posted on July 09, 2012 at 05:03:50 pm
Researchers from Germany, Finland, Scotland, and Switzerland examined tree-ring density profiles in trees from Finnish Lapland. In this cold environment, trees often collapse into one of the numerous lakes, where they remain well preserved for thousands o
Volcanic Ash Preserved Early Animal 'Nursery'
Posted on July 09, 2012 at 04:58:00 pm
A volcanic eruption around 579 million years ago buried a 'nursery' of the earliest-known animals under a Pompeii-like deluge of ash, preserving them as fossils in rocks in Newfoundland, new research suggests
Record-Breaking Expanse of Drought Across U.S.

More of the United States is in moderate drought or worse than at any other time in the 12-year history of the U.S. Drought Monitor, officials from the National Drought Mitigation Center at the University of Nebraska-Lincoln said July 5.
Space Station Experiments Shed Light On Conditions Deep Inside Earth
Posted on June 25, 2012 at 10:31:27 pm
ESA astronaut André Kuipers is running experiments on the International Space Station that are shedding light on conditions deep inside Earth. Orbiting some 400 km above us, Geoflow is offering insights into the inner workings of our planet
Stars, Jets and Batteries for Renewable Energy
Posted on June 20, 2012 at 01:42:48 pm
Magnetic instabilities play a crucial role in the emergence of black holes, they regulate the rotation rate of collapsing stars and influence the behavior of cosmic jets
Ancient Warming Greened Antarctica
Posted on June 19, 2012 at 09:20:49 am
A new university-led study with NASA participation finds ancient Antarctica was much warmer and wetter than previously suspected. The climate was suitable to support substantial vegetation -- including stunted trees -- along the edges of the frozen contin
Plate Tectonics Cannot Explain Early Earth
Posted on June 02, 2012 at 12:19:03 pm
The current theory of continental drift provides a good model for understanding terrestrial processes through history. However, while plate tectonics is able to successfully shed light on processes up to 3 billion years ago, the theory isn't sufficient in
Super-Eruptions With Super Short Fuses
Posted on May 31, 2012 at 06:25:17 am
Enormous volcanic eruptions with potential to end civilizations may have surprisingly short fuses, researchers have discovered.
Climate Change Led to Collapse of Ancient Indus Civilization
Posted on May 30, 2012 at 08:20:08 am
A new study combining the latest archaeological evidence with state-of-the-art geoscience technologies provides evidence that climate change was a key ingredient in the collapse of the great Indus or Harappan Civilization almost 4000 years ago
