Two new studies of gases trapped in Antarctic ice cores have extended the record of Earths past climate almost 50 percent further, adding another 210,000 years of definitive data about the makeup of the Earths atmosphere and providing more evidence of current atmospheric change.
The research is being published in the journal Science by participants in the European Project for Ice Coring in Antarctica. Its “an amazing accomplishment we would not have thought pos
Todays atmospheric carbon dioxide levels are highest in 650,000 years, Science studies say
With the first in-depth analysis of the air bubbles trapped in the “EPICA Dome C” ice core from East Antarctica, European researchers have extended the greenhouse gas record back to 650,000 years before the present.
This 210,000-year extension of atmospheric carbon dioxide and methane records — encompassing two full glacial cycles — should help scientists better underst
What caused the end of a warm climate phase and an expansion of the Antarctic ice sheet 14 million years ago? This is the question addressed by Kiel and Bremen palaeoclimatologists in an article for the latest issue of Nature (24/11/05). Their research uncovered a temporal link between a reduction in carbon dioxide (CO²) levels on earth, ice sheet formation and global cooling. The “global cooling” that took place 14 million years ago is attributed by Dr. Ann Holbourn, Professor Wolfgang Kuhnt, Pr
The successful launch of Ariane 5 Flight 167 leaves the launch campaign of Europes newest meteorological satellite on track to meet its new target date of 21 December.
After 117 days of storage in French Guiana, work began on de-storing and preparing the second Meteosat Second Generation (MSG-2) spacecraft for flight on 31 October. MSG-2 launch campaign activities were officially re-started on 10 November.
MSG-2 had been shipped to Europes spaceport on 21 Jun

The plans for construction of the Eastern Siberia – Pacific Ocean oil-pipe line not only threaten the existence of the last population of the Far Eastern leopard but also Lake Baikal. According to the latest project, the oil-pipe line will go along the route of the Baikal-Amur trank line, less than a kilometer from the northern extremity of the Lake –the town of Severobaikalsk.
“According to the designers’ estimates, in case of an emergency in the pipe line, up to four thousand
