A few of days ago CBC Radio in Canada, interviewed one of the group of European scientists, who is working on a long term ice core drilling project in Antarctica. Apparently they only have another 300 feet to drill before they completete their 3,000 foot core. It is the most complete record of the earth's climate that has ever been obtained.

According to the fellow interviewed, in the overall scheme of long range climate, we are in the middle of a regular interglacial period, which lasts about 25,000 years. Apparently the current CO2 levels are higher than most recorded in the ice record. Although he was concerned regarding the CO2, even with the most sophisticated computer modeling programs, in his opinion, there still was not enough data to make any predictions of catastrophic climate changes in the near future.
