In recent geological history, the so-called Quaternary period, there have been repeated ice ages and warm periods. Researchers are able to determine past climate variability from the composition of ...

Researchers have identified a "tipping point" about 2.7 million years ago when global climate conditions switched from being relatively warm and stable to cold and chaotic, as continental ice sheets ...

The ebb and flow of Pleistocene glacial cycles is not random; it follows a predictable pattern dictated by the distinct and deterministic influence of Earth’s orbital geometry, according to a new ...

Geologists have developed many theories to account for the ebb and flow of glaciers in Europe and North America. Some blame external causes, such as interstellar dust or changes in the earth’s ...

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 to ...
