Bering Land Bridge Was Home To Early Natives For 10,000 Years: Study
2014-02-28 09:47:53

April Flowers for redOrbit.com - Your Universe Online After the ancestors of modern day Native Americans left Asia, they spent approximately 10,000 years living in the shrubby lowlands of the Bering land bridge, according to genetic and environmental evidence. There is no available archaeological evidence, however, because it drowned beneath the Bering Sea when the sea levels rose about 18,000 years ago. Dennis O'Rourke, a University of Utah anthropologist, worked with archaeologist...

Pleistocene Ice Sheet Evidence Uncovered
2013-10-01 04:53:02

April Flowers for redOrbit.com - Your Universe Online Traces of large ice sheets from the Pleistocene on a seamount off the north-eastern coast of Russia have been discovered by a team of geologists and geophysicists from the Alfred Wegener Institute (AWI) Helmholtz Centre for Polar and Marine Research. For the first time, these traces confirm that within the last 800,000 years in the course of ice ages, ice sheets more than approximately a mile thick also formed in the Arctic Ocean....

Last Glacial Maximum Peaked In Spain Much Earlier Than Elsewhere
2013-08-26 14:15:13

Brett Smith for redOrbit.com - Your Universe Online While it’s widely believed that the world’s massive ice sheets were at their greatest extent 20,000 years ago during the last glacial maximum, new research published in Scientific Reports suggested that the glacial peak was much earlier in modern-day Spain. According to study researchers, their findings could inform more localized models of glacier activity and be used to calculate the effects of climate change. “We wanted to...

Compares glacial to global warming. Marlborough, MA, (PRWEB) December 13, 2012 “Tale of the Northwest Passage” has been published to YouTube. This third video in a series compares current climate change to changes observed on a glacial scale. It is the second available on YouTube. “These videos were created as a scientific appendix for the hard Science Fiction eBook Time Arc, a cautionary tale of time travel, and a compelling tale of global warming,” said Frank...

Understanding Antarctic Ice Loss
2012-10-22 19:44:40

Alan McStravick for redOrbit.com — Your Universe Online Amazing GRACE. Scientists and researchers have some interesting news out of Antarctica. The rate of global sea level change has been fairly well-established. The understanding for exactly why this is occurring got a new wrinkle this past week. Utilizing the Gravity Recovery and Climate Experiment (GRACE) satellite data, a team was able to more accurately calculate the ice sheet mass loss by mapping and removing the mass changes...

Desert Climate In West US Affected By Ancient Water Cycle
2012-09-28 09:06:29

Alan McStravick for redOrbit.com - Your Universe Online The climate change we are currently experiencing, while disconcerting and increasingly uncomfortable, is not unprecedented when viewed through the historical prism of life on Earth. A study led by researchers from Texas A&M University's Department of Oceanography looks back at the water cycle that affected the Western United States in an era dating back some 20,000 years. Focusing on the deserts of  Utah and Nevada,...

The cause of rapid sea level rise in the past has been found by scientists at the University of Bristol using climate and ice sheet models. The process, named 'saddle-collapse', was found to be the cause of two rapid sea level rise events: the Meltwater pulse 1a (MWP1a) around 14,600 years ago and the '8,200 year' event. The research is published today in Nature. Using a climate model, Dr Lauren Gregoire of Bristol's School of Geographical Sciences and colleagues unearthed the series of...

Deglaciation Data Opens Door For Earlier First Americans Migration
2012-06-25 04:06:21

A new study of lake sediment cores from Sanak Island in the western Gulf of Alaska suggests that deglaciation there from the last Ice Age took place as much as 1,500 to 2,000 years earlier than previously thought, opening the door for earlier coastal migration models for the Americas. The Sanak Island Biocomplexity Project, funded by the National Science Foundation, also concluded that the maximum thickness of the ice sheet in the Sanak Island region during the last glacial maximum was 70...

Eemian Period Is A Poor Analogue For Current Climate Change
2012-06-15 04:34:14

The Eemian interglacial period that began some 125,000 years ago is often used as a model for contemporary climate change. In the international journal “Geophysical Research Letters” scientists from Mainz, Kiel and Potsdam (Germany) now present evidence that the Eemian differed in essential details from modern climatic conditions. Joint press release of the Academy of the Sciences and the Literature Mainz and the GEOMAR | Helmholtz Centre for Ocean Research Kiel. To address...

Deep sediments are unparalleled record of biotic changes over past 200,000+ years University of California, Berkeley, scientists are drilling into ancient sediments at the bottom of Northern California's Clear Lake for clues that could help them better predict how today's plants and animals will adapt to climate change and increasing population. The lake sediments are among the world's oldest, containing records of biological change stretching back as far as 500,000 years. The core...
