Freeware against mosquitos
A Thai programmer have invented software that can keep mosquitos away from your pc (or so it appears)! The software works by transmitting sound in frequencies not available to the human ear. Mosquitos on the other hand are strongly bothered by the sounds - that can be transmitted in frequencies between 16 kHz and 20 kHz. The software is free to download. (December 20, 2001)

Radioactive waste in the Arctic Ocean
A Norwegian scientist found traces of a radioactive waste product called technitium in the Arctic Ocean. The technitium, that originates from the British nuclear power plant Sellafield, has increased the radio activity in an area off the northern Norway and moved from Britain past Svalbard in to the Arctic Ocean north east of Greenland.

Mud reveals evidence of climate change
Records show that average winter temperatures in Antarctica are more than 5°C higher in parts of Antarctica today than they were 50 years ago. Now geologic evidence in the shape of Antarctic mud reveals evidence of the climate changes. The new evidence suggests that Antarctica experienced periods of extreme warming and cooling long before the invention of the automobile. (December 20, 2001)

Envisat improves sea-ice mapping
In March 2002 the European space agency ESA will launch the environmental satellite Envisat. The Danish Meteorological Institute (DMI) will use data from Envisat to improve the mapping of sea-ice around Greenland. An improvement of the sea-ice mapping will benefit both shipping and climate research. (December 19, 2001)

NGRIP recieves funding
The Carlsberg Foundation has granted Danish ice-core science with a large amount of money for research. Glaciologists are completing the third drill through Greenland's inland ice at NGRIP (75N, 44W). In 2003 they are expecting to reach the bottom more than 3000 meters below the surface. The Glaciology Department is situated at the Niels Bohr Institute for Astronomy, Physics and Geophysics at the University of Copenhagen. (December 19, 2001)

Penguins could abandon Antarctic
New research suggests that Adelie penguins may abandon the Antarctic Peninsula if temperatures continue to increase. Scientists studying fossilised penguin remains near BAS' (British Antarctic Survey) base at Rothera say there were far fewer Adelie penguins here during warmer periods in the past.

+2°C in 100 years
Global mean temperatures have risen almost 2°C over the past 100 years, with more than half of the increase occurring in the last 25 years. In the world of climate change, trends are most readily observed in the Earth's cold regions, where the sensitivity of ice and snow serves as an early indicator of temperature changes. Arctic sea ice extent is decreasing by about three percent per decade. (December 18, 2001)

UK to rebuild Bonner Laboratory
The British Antarctic Survey (BAS) is to rebuild their laboratory in Antarctica after the main research facility was destroyed by a fire in September. All that remains of the original Bonner Laboratory at Rothera is a pile of twisted metal buried in snow. The blaze was probably caused by an electrical fault in the roof of the laboratory.

Antarctic penguin mystery
A mystery disease has killed more than 100 Adelie penguins in Antarctica. It is very unusual to find this kind of large-scale mortality in a colony. Scientists fear that an unknown disease is responsible and are concerned that it could spread. (December 17, 2001)

The past says climate changes in the future
Past climates changed abruptly. Now the past tell the tale of abrupt climate changes in the future, according to an American geoscientist. The abrupt changes are especially notable in temperature near the North and South Poles and in precipitation away from the poles. (December 17, 2001)

Several populations of walrus
Scientists have proven that walruses living in Canada, Greenland and Russia are divided in to at least four seperate sub-populations. The walruses in Greenland consists of three sub-populations - one in North West Greenland, one in the central part of West Greenland and one in East Greenland. (December 12, 2001)

Alaskan glaciers are thinning
Of Alaska's several thousand valley glaciers, including nearly 700 that are named, fewer than 20 are advancing, according to a major study. During the 20th century, most Alaskan glaciers receded and, in some areas, disappeared. The data used in the study does not show wheather or not any of these changes are human induced. (December 12, 2001)

Melting glaciers are raising oceans
Using radar data scientists say they have found that about 1,486 km3 of ice have melted from glaciers in West Antarctica over the past decade. That is enough to raise sea levels worldwide by about 0,4 mm. The findings counter results of an earlier study, drawing on ground-based observations, that concluded that Antarctica was gaining in mass. (December 11, 2001)

Greenlandic volcanoes in cellphones
Tantal is a very rare element used in the batteries of mobile units. Now a Scottish scientist have discovered that tantal can be found in 1.200 million year old volcanoes in Greenland. The Scottish scientist is certain that the key to the future of the mobile industri lies in the mountains surrounding Motzfeldt Lake in Southern Greenland.

Antarctic plants repair themselves
Researchers discovered that the annual ozone hole above Antarctica does not have any visible negative effects on the vegetation. Lichens and mosses have large quantities of protective pigments - or a sort of built in repair mechanism - that protects them from the sun's otherwise harmful UV-radiation. The researchers discovered that this mechanism is also functional even at low temperatures. (December 10, 2001)

Factor leap year in climate research
Don't forget to factor leap year into your calculations when predicting climate change! The good advice comes from researcher Raphael Sagarin. During studies of phenology, which uses historical records of annual bird migrations, ice melts and other natural events to establish trends in global warming, he realized that a lot of phenoligical surveys are based on the calender date rather than on their timing relative to the vernal equinoxz. (December 10, 2001).

Life in Lake Vostok...
Scientists have discovered that the pressure exerted by the continent-wide Antarctic ice-sheet combined with heat generated by the Earth from below may mean that liquid water exists in many - if not all - of the Antarctic sub-glacial lakes including Lake Vostok. According to the scientists behind the new discoveries that may mean that the lakes harbor life. (December 10, 2001)

Cold weather from a warm distance
Meteorologist Matthew Lazzara tries on a daily basis to forecast one of the planet's nastiest climates - Antarctica. From a lab in the US he analyzes climate data from several weather stations scattered all over Antarctica. He then shares his information with other researchers, so they can avoid frost bites and hypothermia. Read an exiting article on how to predict the (almost) unpredictible. (December 5, 2001)

Polar vortex influences the troposphere
Recent observations have suggested that the strength of the polar vortex (strong western winds spinning the stratosphere) influences circulation in the troposphere. Other researchers have noted a statistical correlation between periods when the polar vortex is weak and outbreaks of severe cold in many Northern Hemisphere cities. (December 4, 2001)

Clues to climate change
A new way of using data from satellite-based radar is providing scientists with a unique insight into the effects of climate change on e.g. ice caps, plant life and land surface. The new technique uses data gathered by a radar instrument called a wind scatterometer. The data helps scientists monitor long-term trends over the entire land surface of the Earth.

Scientists investigates penguin deaths
Scientists from Australia's Antarctic Division are to investigate the cause of 99 penguin deaths on two Antarctic islands. There is no outward indication of why the birds died, although it is likely that the deaths are the result of naturally occurring disease. Evidence from from long term monitoring of Adelie penguins suggests that the occurence of dead adult penguins in such numbers is rare and warrents investigation. (December 3, 2001)
