interglacial

We needed to get a GPS location for each clam, as they could have come from different interglacial reef terraces, so we got the guides to take us back to the sites where the clams had been collected.'

Quaternary geologists know well that changes in ocean circulation in the Younger Dryas resulted in a brutal cooling in Europe (and Atlantic Canada!) and that in the Sangamonian interglacial, sea level was about 6 m higher than during our present interglacial.

Changes in deep water circulation may have played an important role in controlling global climate during the geological past, especially during the last million years, a period characterized by cyclical climatic oscillations between ice ages and warm interglacial periods.

Climate scientists have long puzzled over why Antarctic air temperatures have consistently correlated with C[O.sub.2] levels in the atmosphere over the past one million years, with both decreasing during glacial ice ages and increasing during interglacial periods.

The study also shows that when the last ice age ended and the much more humid interglacial period began, the plant composition on the Arctic tundra changed.

Shorter interglacial periods, like the one Earth is in now, are relatively wet because less water is tied up in ice.

The glacial climate that predominated for most of that time was colder and drier, with strikingly larger variability over time, than the more benign interglacial (i.e.

We have been through several previous interglacial periods when our latitude became subtropical.
