In order to reconstruct the climate of past interglacial
periods, she had visited Henderson Island, in the far south-eastern Pacific Ocean, to collect 330 000- and 630 000-year-old fossil corals for climate studies.
Since the end of the present interglacial
and the slow march to the next ice age may be several millennia away, why should we care?
So, melting may progress much farther than it did during earlier interglacial
periods, when that warming influence wasn't in place.
By collecting the drilled cores, the researchers hope to find evidence of how the ice masses of the Antarctic have reacted to sudden temperature climbs in past interglacial
periods information that is urgently needed in order to more accurately predict future sea-level rise.
The abundant corals have taken an easy road to living a rich and dominating life during the present interglacial
period, but the payback comes when the climate becomes less hospitable.
Many scientists believed that this rise in sea levels was mostly due to melting of the Greenland ice sheets, bur the results of the new study suggest that during the last interglacial
, Greenland's ice was more stable--and Antarctica's less stable--than previously thought.
They noted the importance of reduced June insolation for ice sheet growth and suggested that "most C[O.sub.2] scenarios led to an exceptionally long interglacial
from 5000 years before the present to 50,000 years from now ...
Data from those more-modern digs are yielding a wealth of information about the region's ecosystems during recent ice ages and interglacial
In simple terms, this means that there is effectively nothing we can do that will have any effect for many generations and as we live in an interglacial
period when the sea level would be rising anyway our intervention may have no effect at all.
Hydrologist Tom Coulthard of the University of Hull, UK and his colleagues made the climate model of the last interglacial
period to find out how the monsoon rains may have travelled down the trans-Saharan mountains' north face and flowed across the landscape.
When scientists affiliated with the Florida Institute of Technology analysed fossilised pollen trapped in sediments from Lake Titicaca, they found that during two of the past three interglacial
periods, the lake shrank by as much as 85 per cent.
Planet Earth has always moved from Ice Age to warm interglacial
and back to Ice Age without any help from fossil fuels.
