Coal-mining outbursts resemble explosive volcanic eruptionsOctober 2nd, 2009 WASHINGTON - A new research by scientists has suggested that coal outbursts in underground mines occur through a process very similar to what happens during explosive volcanic eruptions. Worldwide, thousands of workers die every year from mining accidents, and instantaneous coal outbursts in underground mines are among the major killers.
Global warming might lead to tsunami hit Britain soon!September 15th, 2009 LONDON - Some of the world's top geologists have warned that if global temperatures continue to rise, Britain might see deadly tsunamis like those that have hit Asia, head towards it in the future. According to a report by Sky News, geologists have warned of tsunamis in Britain to huge avalanches in the Alps and volcanic eruptions in Germany, if global warming continues to rise.
5 last-ditch schemes to prevent global warming disaster (Re-Issue)September 6th, 2009 WASHINGTON - A new study by the United Kingdom's Royal Society has outlined five last-ditch schemes needed to prevent a global warming disaster. According to National Geographic News, United Kingdom's Royal Society's report is the first from a major scientific body devoted to ranking the various proposals for "geoengineering."
"It is an unpalatable truth that unless we can succeed in greatly reducing (greenhouse gas) emissions, we are headed for a very uncomfortable and challenging climate future," said study leader John Shepherd, an earth scientist at the University of Southampton in England, in a statement.

Man-made volcanoes may cool Earth by reflecting sunlight back into spaceAugust 30th, 2009 LONDON - The Royal Society in London seems to be convinced that man-made volcanoes can help stave off climate change, as it is backing research into simulated volcanic eruptions that will spray millions of tons of dust into the air to cool the Earth. This week, the society will call for a global programme of studies into geo-engineering, which can help devise new ways to manipulate the planet's climate to counteract global warming.
Slowing global warming by geo-engineering may increase risk of droughtsAugust 8th, 2009 LONDON - In a new research, scientists have determined that the use of geo-engineering to slow global warming may increase the risk of droughts. Methods put forward include reflecting solar radiation back into space using giant mirrors or aerosol particles.
Volcano explosion didn't cause Earth to go into 'deep freeze' 74,000 years agoJuly 9th, 2009 WASHINGTON - A new study has discounted a theory which suggested that when a giant volcano on Sumatra blew its top 74,000 years ago, the Earth went into deep freeze, cooling the climate by at least 10 degrees Celsius. The volcano, named Toba, may have ejected 1000 times more rock and other material than Mount St.
Glaciers cause quakes in IcelandJuly 4th, 2009 WASHINGTON - A new study has determined that glaciers are the reason behind seismic activity and earthquakes in Iceland. The study was carried out by Kristin Jonsdottir, Roland Roberts, Veijo Pohjola, Bjorn Lund, Zaher Hossein Shomali, Ari Tryggvason, and Reynir Boovarsson from the Department of Earth Science, Uppsala University, Uppsala, Sweden.
Volcano experts say eruptions at Alaska's Mount Redoubt have ceased, lower threat levelJune 30th, 2009 Scientists lower Alaska volcano threat levelANCHORAGE, Alaska — Alaskans can put away their dust masks and spare air filters, for now, because Mount Redoubt seems to have cooled off since its last major eruption nearly three months ago. The Alaska Volcano Observatory said Tuesday that seismic activity has slowed under the volcano and it's possible that eruptions have stopped.
Volcanic blasts kicked off modern ice ages 34 million years agoJune 23rd, 2009 WASHINGTON - Scientists have come up with a new theory that says volcanic blasts gave the Earth its polar ice caps about 34 million years ago, and kicked off a freeze-thaw cycle of ice ages that persists to this day. Until around 34 million years ago the planet was much warmer than it is today, the Arctic was a vast swamp, and Antarctica's mountains were speckled with just a few tiny glaciers.
Global warming may increase dispersal of flora in Northern forestsJune 12th, 2009 WASHINGTON - A new research has indicated that an increase in temperature of only a couple of degrees may increase the dispersal of plants in Northern forests and the spread of plant species into forest clearings after felling or forest fires. The research, in the impact of global warming on seed and pollen dispersal, was led by University of Helsinki researcher Anna Kuparinen.
Scientists find direct relationship between CO2 emissions and global warmingJune 11th, 2009 WASHINGTON - In a new study, a team of scientists has found a direct relationship between carbon dioxide (CO2) emissions and global warming. The study was done by Damon Matthews, a professor in Concordia University's Department of Geography, Planning and the Environment, along with colleagues from Victoria and the UK.
Volcanic eruptions triggered mass extinctions, climate changeJune 5th, 2009 SYDNEY - Massive volcanic eruptions in ancient times triggered rapid climate change and mass extinctions, by ejecting colossal volumes of greenhouse gases into the atmosphere. We have carefully dated minerals contained in the volcanic rocks and shown that only the fastest sequences of eruptions caused significant species extinctions, said Fred Jourdan of Curtin University, Australia.
Giant volcanic eruption 260 mln yrs ago may have caused global mass extinctionMay 29th, 2009 WASHINGTON - Scientists at the University of Leeds in the UK have uncovered a previously unknown giant volcanic eruption that led to global mass extinction 260 million years ago. The eruption in the Emeishan province of south-west China unleashed around half a million cubic kilometers of lava, covering an area 5 times the size of Wales, and wiping out marine life around the world.
CO2 spewing rocks can influence destructive potential of mass extinction eventsApril 22nd, 2009 LONDON - In a new research, scientists have determined that big volcanic eruptions don't always fuel mass extinctions because the destructive potential of the blasts seems to depend upon carbon dioxide (CO2) spewing non-volcanic rocks in the region. Earlier, geologists have found evidence of many huge ancient volcanic eruptions that seem to not be connected to mass extinctions at all.
