Media invitation - Environmental change in Antarctic lakes and seas: the chances for survival or extinction? BA Festival of Science, Univ of Leicester
The effects of the warming of the Earth`s climate on Antarctic lakes and seas is a matter of life or death for many plants and animals at the frozen continent. Professor Lloyd Peck, biologist with British Antarctic Survey (BAS) discusses the prospects for survival or extinction of Antarctic marine and lake life today (9 Sept) at a special seminar... 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...

Discarded human debris threatens global biodiversity
Discarded human debris is encouraging colonization of exotic marine animals in the world`s oceans and threatening global biodiversity, particularly in the Southern Ocean. The findings, reported in this week`s NATURE, are based on a 10-year study of human litter (mostly plastic) washed ashore on 30 remote islands around the globe, from the Arctic... view more...

The first Envisat check-up on the Earth
A major new health check on the Earth got under way on 1 March, when the European Space Agency's Envisat satellite was launched by an Ariane 5 rocket from Europe's spaceport in French Guiana. It is the largest and most sophisticated Earth observation satellite ever built. Following the launch and deployment of the solar panel and antennas, the... view more... (2002-03-28)
Satellite spies on doomed Antarctic ice shelf
Satellite images have revealed the collapse of Larsen B ice shelf on the Antarctic Peninsula fulfilling predictions made by British Antarctic Survey (BAS) scientists. The collapse of the 3250 km2 ice shelf is the latest drama in a region of Antarctica that has experienced unprecedented warming over the last 50 years. Earlier this month Ted Scambos... view more...

UK Princess sees oldest ice on earth
Princess Anne, currently visiting Antarctica, was today given a gift of ice that is 50000 years old. It came from an ice core - a cylinder of ice drilled from the Antarctic ice sheet - drilled by the European Project for Ice Coring in Antarctica (EPICA). EPICA, a consortium of 10 European nations, is drilling two ice cores in Antarctica, in order... view more... (2002-02-08)
Climate change causes extreme changes to Antarctic Lakes
Results from a 20-year study reveal dramatic ecological changes to lakes in Antarctica caused by a 1°C temperature increase. The findings, reported this week in SCIENCE, are yet more evidence of extreme changes in the Antarctic Peninsula region. This area has experienced some of the most rapid warming of anywhere on Earth in the past 50 years... view more... (2002-01-21)
Antarctic Ice Cores - 2002 metres deep as the year 2002 arrives
In the first week of the New Year a team of European scientists reached successfully the depth of 2002 metres of ice at the site of Dome Concordia high on East Antarctica's plateau - one of the most hostile places on the planet. The team, working on a seven-year Antarctic ice core programme to discover the history of the Earth's climate and... view more... (2002-01-15)
Antarctic Ice Core milestone - 2002 m reached as year 2002 arrives
In the first weeks of the New Year a team of European scientists drilled successfully through 2002 metres of ice at Dome Concordia, high on East Antarctica`s plateau - one of the most hostile places on the planet. A specially created laboratory on the ice enabled scientists to analyse, for the first time, past climate shifts within hours of each 3... view more... (2002-01-15)
Antarctic research shows night shift workers at risk from heart disease
Antarctic research shows night shift workers at risk from heart disease Night-shift workers may be at increased risk of developing cardiovascular disease (CVD) according to the latest research conducted in Antarctica. These findings could be of key importance to the UK economy, as a fifth of the country`s workforce are shift workers. A study by Mr... view more... (2001-12-19)
Antarctic plants repair themselves
Dutch researchers funded by NWO have studied the effects of the hole in the ozone layer on the vegetation in Antarctica. The repair mechanisms of lichens and mosses appear to be effective even at low temperatures. Nevertheless, the ecology of the Antarctic is still under threat. The rise in temperature caused by the greenhouse effect is doing... view more... (2001-11-26)
WHEELS WITHIN WHEELS: RARE ORBITAL ANOMALY MAY HAVE CAUSED GLOBAL COOLING 23 MILLION YEARS AGO
A rare coincidence of orbital cycles may have caused sudden global cooling 23 million years (Ma) ago, according to scientists, who used high resolution records and new techniques that allow astronomical calibration to be extended much further back in time. The late Oligocene to early Miocene Earth (20-26 Ma ago) experienced a complex climate... view more... (2001-06-21)
Scientists Detect Thinning West Antarctic Ice.
A major glacial formation in Antarctica is shrinking, a report in SCIENCE will reveal today. But questions still remain about the speed at which ice sheet thinning is taking place. Scientists at University College London (UCL) and the British Antarctic Survey have used satellite data to show that the interior of the West Antarctic Ice Sheet (WAIS)... view more... (2001-01-29)
Carbon dioxide and climate - the plot thickens
Using a novel technique, the researchers obtained a best estimate for carbon dioxide levels 43 million years ago of 385 parts per million (ppm), slightly higher than today's figure of 360 ppm. This result is far below earlier estimates which suggested that carbon dioxide levels were up to six times present day values. There are two ways to... view more... (1999-06-08)
