Ice core reveals a worrying truth about Earth's climate
Scientists drilling in the Antarctic have found evidence that man-made greenhouse gases are causing the planet's climate to destabilise - and could bring on a new ice age in 15,000 years
10 June 2004
The deepest and oldest ice core yet drilled in the Antarctic suggests that the world's climate is headed for an unprecedented period of turmoil brought about by man-made greenhouse gases.
Chemical analysis of the ice within the core - nearly 2 miles long - has revealed details of the eight previous ice ages that have affected the Earth durin the past 740,000 years. Scientists said yesterday that the present climate most closely resembled the warm "interglacial" period about 470,000 years ago, but with the difference that this time temperatures were set to spiral upwards as a result of global warming.
In a study published today in the journal Nature, the international team of scientists from 10 European countries warns that the Earth's climate would now be in a highly stable period if it were not for the extra carbon dioxide being pumped into the atmosphere from human activities. "Given the similarities between this earlier warm period and today, our results may imply that without human intervention, a climate similar to the present one would extend well into the future," the scientists say.
