The team had to drill some 2 miles deep to get enough ice to study a 50,000 year time span. After conducting an extensive ...

For millions of years, these orbital oscillations – known as Milankovitch cycles – brought the planet in and out of glacial ...

The question is again being discussed whether recent and long-continued observations do not point to the advent of a second glacial period, when the countries now basking in the fostering warmth ...

The team compared the changes in orbital parameters to the glacial periods over the last 900,000 years. Eccentricity varies over 100,000-year cycles (and a second one over 400,000 years).

Climate changes usually happens over long periods of time, but during the last glacial period, extreme fluctuations in temperature occurred within just a few years. Researchers have now been able ...

JUST one line in reply to Frank E. Nipher. I have read Tyndall's Lectures on Heat, and that some time before I addressed you on the subject of the Glacial Period. Plainly, it is against common ...

The research raises questions about Earth's other glacial periods, particularly its second, the Cryogenian Period, which lasted from 720 million to 635 million years ago when the Earth is believed ...

IN the many kind and favourable reviews of my book, “The Naturalist in Nicaragua,” exception has been generally taken to my speculations on the extent and effects of the ice of the glacial period.
