Latest Ice core Stories
Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years.
When the climate warmed relatively quickly about 14,700 years ago, seasonal monsoons moved southward, dropping more rain on the Earth's oceans at the expense of tropical areas, according to climate researchers.
At times in the distant past, an abrupt change in climate has been associated with a shift of seasonal monsoons to the south, a new study concludes, causing more rain to fall over the oceans than in the Earth's tropical regions, and leading to a dramatic drop in global vegetation growth.
Dust trapped deep in Antarctic ice sheets is helping scientists unravel details of past climate change.
The Antarctic Peninsula juts into the Southern Ocean, reaching farther north than any other part of the continent. The southernmost reach of global warming was believed to be limited to this narrow strip of land, while the rest of the continent was presumed to be cooling or stable.
Scientists are now making an alarming claim that the earth is on the brink of entering another Ice Age that could last the next 100,000 years.
New research indicates that the ocean could rise in the next 100 years to a meter higher than the current sea level â€“ which is three times higher than predictions from the UN's Intergovernmental Panel on Climate Change, IPCC.
Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics â€” but suggest that such effects may have been masked in the 20th century by rising global temperatures.
Cooperative agreements signed with teams from the University of Wisconsin, Dartmouth College, University of New Hampshire are vital to climate studies
