April Flowers for redOrbit.com - Your Universe Online An international team of scientists, led by Julie Brigham-Grette of the University of Amherst, has analyzed the longest continental sediment core ever collected in the Arctic to provide “absolutely new knowledge” of Arctic climate from 2.2 million to 3.6 million years ago. "While existing geologic records from the Arctic contain important hints about this time period, what we are presenting is the most continuous archive...

Research Provides New Insight Into Snowball Earth Duration
2013-02-28 21:17:15

Lee Rannals for redOrbit.com — Your Universe Online About 635 million years ago, our world was covered in ice during an event called "Snowball Earth," and new details written in the Proceedings of the National Academy of Sciences provide new insight on the duration of this event. According to the Snowball Earth hypothesis, an ice age brought on rapid changes in the atmospheric conditions on our planet, followed by a rapid greenhouse heat wave. This period may have given rise to...

Urine Of The Rock Hyrax Can Give Past Climate Clues
2013-02-18 08:40:23

Brett Smith for redOrbit.com - Your Universe Online Not cleaning a kitty´s litter box could be a disgusting thought for cat owners, but for Brian Chase of Montpellier University in France – layers of dried urine can reveal exciting new details about an environment as they stack up year after year and generation after generation. Instead of learning about the historical habitat of the common housecat, Chase and his colleagues from the European Research Council analyzed layers...

Greenland Ice Core Research Points To Higher Seas, Warmer Past
2013-01-24 11:07:31

Brett Smith for redOrbit.com - Your Universe Online New research findings based on Greenland ice cores show that if climate change patterns repeat themselves, the Earth will become much warmer and sea levels will rise significantly. In a new report published in the latest edition of the journal Nature, scientists have used Greenland ice cores over 1.5 miles long to collect data on the Eemian period, around 115 to 130 thousand years ago. An analysis of the cores allowed the international...

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...

Rising Temperatures Could Lead To Sea Levels Rising Three Feet Or More
2012-11-15 13:56:59

April Flowers for redOrbit.com - Your Universe Online A rapid response between global temperatures and ice volume/sea-level that could lead to sea-levels rising by over 3 feet have been revealed by a new study from the University of Southampton. Global ice-volume variability has been one of the main feedback mechanisms in climate change during the last few million years. This is because of the strong reflective properties of large ice sheets. Scientists reconstruct ice volume...

Atlantic Heat Pump Was Once Faster
2012-10-16 13:39:01

April Flowers for redOrbit.com - Your Universe Online A new study from an international team of scientists led by environmental physicists at Heidleberg University in Germany suggests that the circulation of the Atlantic Ocean was faster during the last Ice Age than today. It has long been assumed that heat transport in the Atlantic Ocean during the last Ice Age was weaker, but according to the new data, it appears that it was actually stronger than it currently is. The team used...

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,...

Eltanin meteor
2012-09-20 04:27:37

April Flowers for redOrbit.com - Your Universe Online Around 2.5 million years ago, a huge meteor collided with the Earth and fell into the southern Pacific Ocean. A new study, published in the Journal of Quaternary Science, suggests that not only could this have caused a massive tsunami, but it may also have plunged the world into the Ice Ages. A research team from Australia says that because the Eltanin meteor — which was up to two kilometers across — crashed into deep...
