The paradox of polar ice sheet formation solved

The beginning of the last glacial period was characterized in the Northern hemisphere by major accumulation of snow at high latitudes and the formation of a huge polar ice sheet. For climatologists this was paradoxical, since ...

Sea level influenced tropical climate during the last ice age

Scientists look at past climates to learn about climate change and the ability to simulate it with computer models. One region that has received a great deal of attention is the Indo-Pacific warm pool, the vast pool of warm ...

Pottery reveals Ice Age hunter-gatherers' taste for fish

Hunter-gatherers living in glacial conditions produced pots for cooking fish, according to the findings of a pioneering new study led by the University of York which reports the earliest direct evidence for the use of ceramic ...
