U.S. geoscientists say they've found evidence that northern hemisphere climate swings during the past 12,000 years are linked to changes in the tropics. University of New Hampshire and Columbia University scientists said their finding suggests a prolonged cold spell caused European and North American glaciers to creep forward several hundred years ago, possibly affecting climate patterns as far south as Peru and causing tropical glaciers to also expand. Glaciers in both the tropics and North...

British scientists say they have created a model of the British and Irish ice sheets that shows they moved in unexpected ways. Durham University researchers said their model reveals for the first time how the glaciers reversed their flows and retreated back into upland regions from where they originated. During the last glacial maximum, around 21,500 years ago, the ice sheets built up on the high land of the Lake District, north Pennines and Scottish Southern Uplands, the researchers said. As...

An international team of scientists, led by Denmark, says it set a single-season deep ice core drilling record this summer in Greenland. The researchers, with the University of Colorado at Boulder as the lead U.S. institution, recovered more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future. The project, known as the North Greenland Eemian Ice Drilling, is being undertaken by 14 nations led by the University of...

A new 2,000-year-long reconstruction of sea surface temperatures (SST) from the Indo-Pacific warm pool (IPWP) suggests that temperatures in the region may have been as warm during the Medieval Warm Period as they are today.The IPWP is the largest body of warm water in the world, and, as a result, it is the largest source of heat and moisture to the global atmosphere, and an important component of the planet's climate. Climate models suggest that global mean temperatures are particularly...

The first season of the international drilling project NEEM (North Greenland Eemian Ice Drilling) in north-western Greenland was completed at August 20th. A research team, with the participation of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association, has drilled an ice core of altogether 1757.87 m length on the Greenland inland ice within 110 days. It is expected to contain data on climate history of about 38.000 years. The oldest ice comes from a period...

When Planet Earth was just cooling down from its fiery creation, the sun was faint and young. So faint that it should not have been able to keep the oceans of earth from freezing. But fortunately for the creation of life, water was kept liquid on our young planet. For years scientists have debated what could have kept earth warm enough to prevent the oceans from freezing solid. Now a team of researchers from Tokyo Institute of Technology and University of Copenhagen's Department of Chemistry...

 Researchers have largely put to rest a long debate on the underlying mechanism that has caused periodic ice ages on Earth for the past 2.5 million years "“ they are ultimately linked to slight shifts in solar radiation caused by predictable changes in Earth's rotation and axis.In a publication to be released Friday in the journal Science, researchers from Oregon State University and other institutions conclude that the known wobbles in Earth's rotation caused global ice levels to...

Findings are relevant to modern Greenland ice sheet, says UB researcher Modern glaciers, such as those making up the Greenland and Antarctic ice sheets, are capable of undergoing periods of rapid shrinkage or retreat, according to new findings by paleoclimatologists at the University at Buffalo. The paper, published on June 21 in Nature Geoscience, describes fieldwork demonstrating that a prehistoric glacier in the Canadian Arctic rapidly retreated in just a few hundred years. The proof of...

Study offers detailed look at past greenhouse gas levels Researchers have reconstructed atmospheric carbon dioxide levels over the past 2.1 million years in the sharpest detail yet, shedding new light on its role in the earth's cycles of cooling and warming. The study, in the June 19 issue of the journal Science, is the latest to rule out a drop in CO2 as the cause for earth's ice ages growing longer and more intense some 850,000 years ago. But it also confirms many researchers' suspicion...
