CAMBRIDGE, England, Jan. 9 (UPI) -- Human emissions of greenhouse gases, particularly carbon dioxide, will delay the Earth's next Ice age, European, Canadian and U.S. scientists say.
An international team of researchers says data on historical warm interglacial periods most like the current one suggest the Earth would be due for another Ice Age in 1,500 years, but human emissions have been so high it could be pushed farther into the future.
