...years. Before that, however, it gets murkier. That's largely because ice and air that old haven't yet been found. So scientists rely instead on indirect measurements - and these have led to a climate mystery: some episodes of past warming, including a planetary heat wave about 15 million years ago and another about 3.5 million years ago, seem to have happened without a rise in CO2. No one quite understands why. Maybe other greenhouse gases were the cause - methane, for example. Or maybe it had to do with changes in ocean circulation. (See pictures of the world's most...
...they're right, it could be pretty bad news, even for those who already worry about rising CO2. It's generally agreed that during the earlier warm period, known as the Miocene Climatic Optimum, which occurred 15 million years ago, the global temperature was high enough to make sea levels between 80 ft. and 130 ft. higher than they are today. According to the new study, CO2 levels in the atmosphere at that time hovered at from 390 to 430 parts per million (p.p.m.). Today's CO2 level: 387 p.p.m. and rising...

...wealthy city is making a surprising bid to become one of the world's most important markets for fine wines. Last weekend marked another milestone: In the second of its two major wine auctions held this year in Hong Kong, Sotheby's on Oct. 3 and 4 sold $7.9 million worth of vintage wines, taking the house's total wines sales in Hong Kong to $14.3 million in 2009 - eclipsing its sales totals of $10.5 million in New York and $8 million in London. Although New York is expected to remain overall the largest market for vintage vino...
