First evidence of under-ice volcanic eruption in Antarctica
The first evidence of a volcanic eruption from beneath Antarctica's most rapidly changing ice sheet is reported this week in the journal Nature Geosciences. The volcano on the West Antarctic Ice Sheet erupted 2000 years ago (325BC) and remains active. view more (2008-01-21)
MESSENGER discovers an unusual impact basin on Mercury
A previously unknown, large impact basin has been discovered by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft during its second flyby of Mercury in October 2008. view more (2009-05-01)
New theory for mass extinctions
A new theory on just what causes Earth's worst mass extinctions may help settle the endless scientific dust-up on the matter. view more (2006-10-25)
El Ni'ħo was more intense 4000 years ago
Examination of fossil corals on Vanuatu have enabled scientists from IRD (Institut de recherche pour le développement, ex-Orstom) based at Noumea to reconstruct the sequence of variations in sea surface temperature (SST) in the southwest Pacific Ocean that occurred over a period of 50 years, 4200 years B. P. (in the Holocene). Although... view more... (2000-11-07)
British oceanographers find 'smoking' submarine volcano in the Indian Ocean
At over three thousand metres down in the north-west Indian Ocean, the Carlsberg Ridge is "probably the best ridge in the world". So say excited scientists from Southampton Oceanography Centre who have just found the first evidence of hydrothermal activity in this previously unexplored area of a volcanic mid-ocean ridge. The team aboard... view more... (2003-07-29)
Volcanoes played pivotal role in ancient ice age, mass extinction
Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago. Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began. view more (2009-10-27)
Three ESA satellites reveal Etna's complexity
As detected by ESA satellite sensors, the recent eruptions of the Mount Etna volcano in Sicily are throwing huge amounts of ash and trace gases into the atmosphere. Working with data from the Global Ozone Monitoring Experiment (GOME) sensor onboard ESA's ERS-2 spacecraft, scientists at the German aerospace centre (DLR) report that levels of... view more...

New report presents strongest evidence yet of human link to global warming, Duke expert says
Evidence presented in the first phase of the Intergovernmental Panel on Climate Change's 4th Assessment Report, released today in Paris, paints the clearest picture yet that human-derived greenhouse gases are playing a significant role in observed global warming. view more (2007-02-02)
Up, Up and Away: Studying Volcanoes With Balloon
People do all kinds of crazy things in Hawaii, but flying balloons over a volcano usually isn't one of them. Unless you're Adam Durant, that is. view more (2008-08-15)
Obsidian 'trail' provides clues to how humans settled, interacted in Kuril Islands
Archaeologists have used stone tools to answer many questions about human ancestors in both the distant and near past and now they are analyzing the origin of obsidian flakes to better understand how people settled and interacted in the inhospitable Kuril Islands. view more (2009-06-23)
Sierra Nevada rose to current height earlier than thought, geologists say; implications for modeling global climate
Geologists studying deposits of volcanic glass in the western United States have found that the central Sierra Nevada largely attained its present elevation 12 million years ago, roughly 8 or 9 million years earlier than commonly thought. view more (2008-04-24)
In new study, ancient and modern evidence suggests limits to future global warming
Instrumental readings made during the past century offer ample evidence that carbon dioxide and other "greenhouse gases" in the atmosphere are warming Earth's climate, a team led by Duke University scientists has reported. view more (2006-04-20)
ESA's Envisat captures breath of volcano
Indonesia's Mount Gamkonora volcano is spewing hot ash and smoke into the air, as seen in this image taken by the MERIS instrument aboard ESA's satellite Envisat, causing more than 8000 people to be evacuated amid fears of an imminent eruption, according to officials. view more (2007-07-12)
New window into ancient ozone holes
British researchers have hit on a clever way to search for ancient ozone holes and their relationship to mass extinctions: measure the remains of ultraviolet-B absorbing pigments ancient plants left in their fossilized spores and pollen. view more (2005-08-10)
Ancient Turtle Migrated from Asia to America Over a Tropical Arctic
In Arctic Canada, a team of geologists from the University of Rochester has discovered a surprise fossil: a tropical, freshwater, Asian turtle. view more (2009-02-02)
Cosmic bogs @ the London Catastrophes conference
You may think that peat bogs are among the least interesting places on Earth and you could be right. But according to speakers at Brunel University`s `Environmental Catastrophes` conference, that doesn`t stop them being excellent recorders of catastrophic environmental events like volcanic eruptions and cosmic influx. According to Dr Lars... view more... (2002-08-17)
Great Indian Ocean earthquake of 2004 set off tremors in San Andreas fault
In the last few years there has been a growing number of documented cases in which large earthquakes set off unfelt tremors in earthquake faults hundreds, sometimes even thousands, of miles away. view more (2008-12-11)
Aurorae and Volcanic Eruptions
Impressive thermal-infrared images have been obtained of the giant planet Jupiter during tests of a new detector in the ISAAC instrument on the ESO Very Large Telescope (VLT) at the Paranal Observatory (Chile). They show in particular the full extent of the northern auroral ring and part of the southern aurora. A volcanic eruption was also imaged... view more... (2001-06-07)
Models play important role in understanding extreme weather
Weather is a hot topic here in Interior Alaska and a quick way to get anyone talking. Not a day goes by in winter months without some observations of temperatures, air inversions, or even a mention that the sun budged another degree above the horizon. view more (2007-03-29)
European Satellites Probe a New Magnetar
On Aug. 22, 2008, NASA's Swift satellite reported multiple blasts of radiation from a rare object known as a soft gamma repeater, or SGR. view more (2009-06-17)
