Finding an answer to Darwin's Dilemma
The sudden appearance of large animal fossils more than 500 million years ago - a problem that perplexed even Charles Darwin and is commonly known as "Darwin's Dilemma" - may be due to a huge increase of oxygen in the world's oceans, says Queen's paleontologist Guy Narbonne, an expert in the early evolution of animals and their... view more...

Are the Alps growing or shrinking?
The Alps are growing just as quickly in height, as they are shrinking. This paradoxical result could be proven by a group of German and Swiss geoscientists. view more (2009-11-06)
Researchers plumb mysteries of Antarctic Mountains
The 3,000-kilometer-long Transantarctic Mountains are a dominant feature of the Antarctic continent, yet up to now scientists have been unable to adequately explain how they formed. view more (2007-07-20)
Glaciers Reveal Martian Climate Has Been Recently Active
The prevailing thinking is that Mars is a planet whose active climate has been confined to the distant past. About 3.5 billion years ago, the Red Planet had extensive flowing water and then fell quiet - deadly quiet. It didn't seem the climate had changed much since. view more (2008-04-24)
UK glaciologists warn of global warming threat to South American World Heritage Site
Leading UK scientists fear that one of South America's leading natural tourist destinations, the San Rafael Glacier in Patagonian Chile, which is renowned for the spectacular way in which it releases icebergs into the San Rafael Laguna, may soon retreat to a point where it no longer reaches the sea. This, they warn, might remove one of the main... view more... (2004-04-26)
A rapidly changing Earth
Tropical glaciers in the Andes of Peru and the Mt Kilimanjaro ice fields of East Africa are retreating at such alarming rate that, if current warming trends continue, they could be completely ice free within 10-20 years, says glaciologist, Professor Lonnie Thompson from Ohio State University. According to Professor Thompson, Quelccaya in Peru,... view more... (2001-02-14)
Mars With Ice, Shaken, Not Stirred
Mars, like Earth, is a climate-fickle water planet. The main difference, of course, is that water on the frigid Red Planet is rarely liquid, preferring to spend almost all of its time traveling the world as a gas or churning up the surface as ice. view more (2007-10-26)
Satellites shed light on global warming
As climate change continues to make headlines across the world, participants at the 2007 Envisat Symposium this week are hearing how Earth observation satellites allow scientists to better understand the parameters involved in global warming and how this is impacting the planet. view more (2007-04-30)
Ancient drought and rapid cooling drastically altered climate
Two abrupt and drastic climate events, 700 years apart and more than 45 centuries ago, are teasing scientists who are now trying to use ancient records to predict future world climate. view more (2009-06-19)
Foretelling a major meltdown
By discovering the meaning of a rare mineral that can be used to track ancient climates, Binghamton University geologist Tim Lowenstein is helping climatologists and others better understand what we're probably in for over the next century or two as global warming begins to crank up the heat - and, ultimately, to change life as we know it. view more (2008-12-02)
Egg-shaped legacy of Britain's mobile ice-sheet
The ice sheets that sculpted the landscape of northern Britain moved in unexpected ways and left distinctive egg-shaped features according to new research. view more (2009-09-16)
The high mountain station in the Pamirs was destroyed by bandits
More than thirty years ago V.K.Nosdruhin, the expedition chief of the Central Asia Hydrometeorological Institute, proposed to organize a stationary base to observe glaciers. The base was placed on the Abramov glacier in the Pamirs. This place, in the Alaisky ridge, is a most beautiful one. The observatory with three subdivisions was constructed by... view more...

Alberta's hidden valleys offer both resources and danger
Alberta is crisscrossed with hidden glacial valleys that hold both resource treasures and potential danger. University of Alberta researcher Doug Schmitt discovered a 300 metre deep, valley hidden beneath the surface of the ground near the community of Rainbow Lake in northwestern Alberta. view more (2009-11-13)
Western prairies face impending water crisis
The Canadian prairies are facing an unprecedented water crisis due to a combination of climate warming, increase in human activity and historic drought. view more (2006-04-04)
First British Glacial Map to predict future climate change
An academic from the University of Sheffield has produced the first glacial map of Britain, which could allow us to better predict climate change in the future. The map is published in the latest edition of the journal Boreas. view more (2004-11-23)
NASA provides new perspectives on the earth's changing ice sheets
It's widely documented that climate change is causing the Greenland and Antarctic ice sheets to shrink. Air temperatures in many parts of the polar regions have increased and waters that surround parts of the ice sheets have warmed up. view more (2006-12-12)
Snows of Kilimanjaro disappearing, glacial ice loss increasing
Five years after warning that the famed ice fields on Tanzania 's Mount Kilimanjaro may melt, Ohio State University researchers have sadly found that their prediction is coming true. view more (2006-02-14)
Antarctic research helps shed light on climate change on Mars
Researchers examining images of gullies on the flanks of craters on Mars say they formed as recently as a few hundred thousand years ago and in sites once occupied by glaciers. The features are eerily reminiscent of gullies formed in Antarctica's mars-like McMurdo Dry Valleys. view more (2008-08-29)
Science From Space
Scientists working at the Bristol Glaciology Centre at the University of Bristol will be staying up all night to watch the lift-off of the largest and most powerful Earth observation satellite ever to be launched by the European Space Agency. The satellite, called ENVISAT, is 25 metres high, ten metres wide and weighs over eight tons. Fully... view more... (2002-02-28)
Fossil record supports evidence of impending mass extinction
Global temperatures predicted for the coming centuries may trigger a new 'mass extinction event', where over 50 per cent of animal and plant species would be wiped out, warn scientists at the Universities of York and Leeds. view more (2007-10-24)
