Global warming could lead to a greener Greenland (embargoed until 18.00 BST)
Research published in Nature suggests that enough greenhouse gases could be in the atmosphere as early as 2050 to melt the massive ice-sheet that covers Greenland. As a result, sea levels could rise by around seven metres over the next 1,000 years. Along with colleagues in Belgium and Germany, Dr Jonathan Gregory, of the Centre for Global... view more...

Antarctic seabirds and climate change
Recent changes in Antarctic seabird populations may be linked to environmental change according to scientists reporting in the journal Science this week. Researchers from the Cambridge-based British Antarctic Survey (BAS) reviewed the best available data from a range of long-term studies to test the view that warming of the Earth`s climate is... view more...

New research provides insight into ice sheet behavior
A new study published this week takes scientists a step further in their quest to understand how Antarctica's vast glaciers will contribute to future sea-level rise. view more (2009-07-21)
Researchers say Arctic sea ice still at risk despite cold winter
Using the latest satellite observations, NASA researchers and others report that the Arctic is still on "thin ice" when it comes to the condition of sea ice cover in the region. A colder-than-average winter in some regions of the Arctic this year has yielded an increase in the area of new sea ice, while the older sea ice that lasts for... view more... (2008-03-19)
Robot submarine reveals secret stash of key Antarctic food source under sea ice
A robot submarine expedition under the Antarctic sea ice has discovered a major food reserve in the Southern Ocean. The findings, reported this week in SCIENCE, show a dense band of the shrimp-like krill under the ice, five times more concentrated than in open water. The importance of sea ice as a nursery for krill - key food for penguins, whales... view more... (2002-03-05)
Global warming may not have ended Ice-Age, says research
Scientists at the University of Sheffield have used fossilised leaves to determine the effect of greenhouse gases on the end of the Ice Age 300m years ago, according to an article published in PNAS. The study, led by Professor David Beerling, examined fossilised leaves to determine how much carbon dioxide was in the air at various periods during... view more... (2002-09-12)
Frozen methane chunks not responsible for abrupt increases in atmospheric methane
Icy chunks of frozen methane and water are not responsible for the periodic increases in atmospheric methane recorded in Greenland ice cores. view more (2006-02-10)
Strengthening case for life on Mars - CMD19CMMP with The Physics Congress 2002
When it was announced last month that the Mars Odyssey satellite had found water ice beneath the planet`s frozen carbon dioxide south polar ice cap, "I felt excited!" says Dr Lidija Siller, a physicist from the University of Newcastle. "I believe that the data I have explains how this water became trapped underneath the surface". Dr Siller will be... view more... (2002-03-26)
Scientists Detect Melting of Antarctic Ice Shelf
A giant ice shelf the size of Scotland is melting rapidly in warm Antarctic waters, a report in SCIENCE will reveal today. Thinning of the Larsen Ice Shelf - vast sections of which collapsed catastrophically during the 1990's - was discovered by scientists at the University of Cambridge, University College London, University of Bristol and the... view more...

Forecasting where and when the rain will fall
Leeds researchers are aiming to unlock the secrets of the British weather, bringing forecasters one step closer to that elusive holy grail: the ability to predict exactly where, when and how much rain is going to fall. Dr Alan Blyth from the school of the environment explains: "There's still a lot we don't know about exactly how rain is... view more... (2003-11-24)
Arctic Sea ice extent is third lowest on record
U.S. satellite measurements show Arctic sea ice extent in 2009 - the area of the Arctic Ocean covered by floating ice - was the third lowest since satellite measurements were first made in 1979. view more (2009-10-07)
New Glacier Outburst Flood in Iceland
On July 9th researchers from Keele and Staffordshire Universities and the Icelandic Meteorological Office identified the source and drainage routes of a glacier outburst flood or 'jokulhlaup' which is currently draining from the western margin of Vatnajokull ice cap. The team are currently part of an Earthwatch funded project based at Skaftafell... view more... (2002-07-09)
Why is Greenland covered in ice?
There have been many reports in the media about the effects of global warming on the Greenland ice-sheet, but there is still great uncertainty as to why there is an ice-sheet there at all. view more (2008-08-28)
Earth's heat adds to climate change to melt Greenland ice
Scientists have discovered what they think may be another reason why Greenland's ice is melting: a thin spot in Earth's crust is enabling underground magma to heat the ice. They have found at least one "hotspot" in the northeast corner of Greenland -- just below a site where an ice stream was recently discovered. view more (2007-12-13)
No Core In Volcanoes
A hot debate in the Earth Sciences is finally resolved in this week's issue of Nature. Researchers from the Department of Earth Sciences at Bristol University show that large volcanoes do not contain material from the Earth's core. This overturns previous theories that conflicted with models of how the Earth's magnetic field is sustained. The... view more... (2004-01-12)
Record warm summers cause extreme ice melt in Greenland
An international team of scientists, led by Dr Edward Hanna at the University of Sheffield, has demonstrated that recent warm summers have caused the most extreme Greenland ice melting in 50 years. view more (2008-01-16)
Water at Martian south pole
Thanks to ESA's Mars Express, we now know that Mars has vast fields of perennial water ice, stretching out from the south pole of the Red Planet. Astronomers have known for years that Mars possessed polar ice caps, but early attempts at chemical analysis suggested only that the northern cap could be composed of water ice, and the southern cap... view more...

Greenland and Antarctic ice sheet melting, rate unknown
The Greenland and Antarctica ice sheets are melting, but the amounts that will melt and the time it will take are still unknown, according to Richard Alley, Evan Pugh professor of geosciences, Penn State. view more (2009-02-17)
