Prehistoric times

Greenland icebergs may have triggered the Younger Dryas

Just as the last Ice Age was drawing to a close, Greenland icebergs changed the temperature in the Atlantic and triggered a 1,000-year-long extension of the Ice Age.

Early Earth was pounded into pieces

Scientists have found evidence of a previously unknown meteor bombardment of Earth some 4.3 to 4.1 billion years ago.

Remarkable climate details in Antarctic ice core

An ice core extracted from the West Antarctic Ice Sheet reveals in unprecedented detail how the weather in the Antarctic has changed over the past 68,000 years. The ice core may also tell us how future climate change will affect the frozen continent.

Danish pollen reveals new interglacial period

New analysis of rare Danish soil layers reveals a hitherto unknown temperate period during the Ice Age.

Surprisingly few major Ice Ages in southwest Greenland

The waters off southwest Greenland have escaped extremely large and thick ice sheets during most of the Ice Ages, new research reveals.

Oceans drive climate change

Researchers say that changes in the climate can be traced in the ocean hundreds of years before there is any trace of it in the atmosphere.

How far north did the Neanderthals go?

Archaeologists are disagreeing about whether or not the Neanderthals travelled all the way up to Scandinavia. A new research project seeks to settle the dispute once and for all.

Fish corrupt Carbon-14 dating

Danish Stone Age settlements may have been misdated by up to 2,000 years. In sites where people ate fish, there might well be errors in the Carbon-14 dating of clay vessels.

New technique reveals rare pattern on Stone Age adze

Engravings on a 10,000-year-old elk-antler prong adze emerged after it had been on exhibition for 50 years. Here, the researchers explain about the RTI technique that led them to the discovery of the concealed symbols.

Sun-kissed sulphur reveals volcanic effects on climate

Remains from the most powerful volcanic eruptions were branded by the sun before they ended up buried under the polar ice. This discovery enables scientists to find out when the volcanoes controlled the climate.
