Eruption yields bad news for iron fertilization-based geoengineering schemes
(03/22/2013) Geoengineering schemes that aim to slow global warming by seeding oceans with iron to boost carbon dioxide-absorbing phytoplankton may not lead to long-term sequestration of the important greenhouse gas, finds a new study published in the journal Geophysical Research Letters.
New species of bioluminescent cockroach possibly already extinct by volcanic eruption
(11/14/2012) While new species are discovered every day, Peter Vršanský and company's discovery of a light-producing cockroach, Lucihormetica luckae, in Ecuador is remarkable for many reasons, not the least that it may already be extinct. The new species represents the only known case of mimicry by bioluminescence in a land animal. Like a venomless king snake beating its tail to copy the unmistakable warning of a rattlesnake, Lucihormetica luckae's bioluminescent patterns are nearly identical to the poisonous click beetle, with which it shares (or shared) its habitat.
Navy discovers 10,000-sq mile patch of floating rock in South Pacific (photos)
(08/11/2012) New Zealand's Royal Navy has found a 10,000-square mile (26,000-square kilometer) patch of pumice floating on the surface of the South Pacific Ocean, reports the agency.
Prominent climate skeptic reverses course, says global warming worse than IPCC forecast
(07/30/2012) After starting his own project to study global warming, a once-prominent climate change skeptic and physicist says he now accepts the reality of anthropogenic climate change. "Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I'm now going a step further: Humans are almost entirely the cause," Richard Muller writes in the New York Times as his team, the Berkeley Earth Project, releases a new paper that finds an even stronger link between greenhouse gas emissions and rising temperatures worldwide than the Intergovernmental Panel on Climate Change (IPCC).
Volcano and cloud forests conserved in Ecuador
(12/05/2011) Conservation organizations and the Ecuadorian government have succeeded in securing over 250,000 acres (106,000 hectares) of cloud forest and grasslands surrounding the Antisana Volcano for protection. The area, long-used for cattle ranching, is home to Andean condors (Vultur gryphus), cougars (Puma concolor), Andean fox (Lycalopex culpaeus), silvery grebes (Podiceps occipitalis), black-faced ibis (Theristicus melanopis), spectacled bear (Tremarctos ornatus), and three species of endangered frogs. The protected area stretches from 3,900 feet (1,188 meters) to 18,700 feet (5,699 meters) above sea level.
Permian mass extinction caused by giant volcanic eruption
(05/28/2009) Two hundred and sixty million years ago the Earth experienced its worst mass extinction: 95 percent of marine life and 70 percent of terrestrial life vanished. Long a subject of dispute, researchers from the University of Leeds believe they have confirmed the reason behind the so-called Permian extinction.

(12/03/2007) Mexico's Popocatepetl volcano erupted several times on Saturday, December 1, ejecting steam and ash, according to Mexico's National Disaster Prevention Center (CENAPRED).
Geoengineering cure for global warming could cause problems
(08/14/2007) Proposed geoengineering schemes to reduce global warming may do more harm than good, warns a new study published in Geophysical Research Letters.
Volcanoes linked to massive global warming event
(04/26/2007) Scientists have linked a sharp spike in ocean temperatures 55 million years ago to massive volcanic eruptions that created the North Atlantic Ocean when Greenland and northwestern Europe separated.
Volcanic eruptions in Iceland shrunk Nile River
(11/21/2006) A series of volcanic eruptions in Iceland in the 18th century dramatically impacted the mighty Nile River according to a new study published in Geophysical Research Letters. The research, partly funded by NASA, shows that volcanic eruptions in high latitudes can greatly alter global climate and distant river flows. The scientists found that Iceland's Laki volcanic event, a series of roughly ten eruptions from June 1783 through February 1784, altered atmospheric circulations across much of the Northern Hemisphere, reducing rainfall over much of the Nile River watershed and producing record low river levels. The researchers said that the Laki event had a significant impact on climate because it released large amounts of aerosol-forming sulfur dioxide into the atmosphere. The aerosols, which cool climate by reflecting incoming sunlight into space, may have reduced the average temperature over Northern Hemisphere land masses by as much as 3 degrees Celsius in the summer of 1783, according to computer models used in the study.
With volcanic eruption looming, group plans animal evacuation
(05/04/2006) The seismic record of Merapi Volcano in Central Java is presently showing increase activities. The Directorate of Volcanology and Geological Hazzard Mitigation has raised the alert level from II to III on 12th April. The authority estimated that the volcano would most likely erupt soon, in the next two weeks.
Java volcano may erupt soon
(04/25/2006) Residents living around Mount Merapi on the island of Java are preparing to flee if the volcano erupts, according to a report from Reuters. The volcano, which has been spewing smoke for almost two weeks, has killed nearly 1,400 people in two eruptions since 1930. According to Reuters, government officials have advised residents to leave the foothills of the volcano, but have not made any official orders. Vulcanologists say that the volcano could erupt by the end of April.
Volcanic eruption cut warming in 20th century
(02/09/2006) Ocean temperatures might have been warmer and sea levels would have risen higher in the 20th century had Krakatoa not erupted in 1883, said a team of scientists. According to the researchers, the release of ashes and aerosols into the upper atmosphere had a significant long-term impact on global climate.
Photos of erupting volcano in Vanuatu
(12/07/2005) The Manaro Volcano of Ambae Island, Vanuatu in the South Pacific erupted in spectacular fashion early Thursday. The volano shot steam, toxic gases and ash up to 1,500 meters (4,500 feet) into the air.
Poisonous volcanic gas probably caused worst mass extinction says new study
(12/02/2005) The mass extinction event at the end of the Permian -- where more than two-thirds of reptile and amphibian families perished and 95% of oceans life forms became extinct -- was probably caused by poisonous volcanic gas, according to research published in the journal Geology. The researchers believe that volcanic gases from the eruption depleted earth's protective ozone layer and acidified the land and sea.
