Greenland Ice Sheet Collapse Linked To Sea Level Rise 400,000 Years Ago: Study
2014-06-26 03:26:40

Oregon State University A new study suggests that a warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold, resulting in a nearly complete deglaciation of southern Greenland and raising global sea levels some 4-6 meters. The study is one of the first to zero in on how the vast Greenland ice sheet responded to warmer temperatures during that period, which were caused by changes in the Earth's orbit around the sun. Results of the study,...

KIGAM Overturns common ideas about the different types of climate changes between the middle latitude areas of the Northern and Southern Hemispheres Korean research team revealed conflicting climate change patterns between the middle latitude areas of the Northern and Southern Hemispheres in relation to glacial and interglacial cycles which have been puzzled for the past 60 years. Doctor Kyoung-nam Jo from the Quaternary Geology Department of the Korea Institute of Geoscience and...

European Association of Geochemistry Two studies show that the movement rate of plates carrying the Earth's crust may not be constant over time. This could provide a new explanation for the patterns observed in the speed of evolution and has implications for the interpretation of climate models. The work is presented today at Goldschmidt 2014, the premier geochemistry conference taking place in Sacramento, California, USA. The Earth's continental crust can be thought of as an archive...

High Tibet May Have Been Starting Point For Cold-Adapted Mammals

Gerard LeBlond for redorbit.com - Your Universe Online Over the past 2.5 million years, the Earth has gone through changes in climate. Warm and cold cycles, some lasting for millennia, have become known as the Ice Age. During the cold cycles, ice sheets covered large areas of the northern hemisphere and as the ice melted during the warm cycles, the glaciers receded leaving huge valleys behind. These cycles also affected the evolution and distribution of animals, including the ones living...

April Flowers for redOrbit.com - Your Universe Online Climatologists use deep-drilled ice core samples in order to understand the climate changes our planet has endured during and between the Ice Ages. A team of scientists has recently developed a new technique, described in the Proceedings of the National Academy of Sciences, to confirm the age of a 120,000-year-old sample of Antarctic Ice. Scientists will be able to use the new dating technique to identify ice that is much older,...

Atlantic Ocean Dances With The Sun And Volcanoes
2014-04-01 09:06:11

By Christina Troelsen, Aarhus University Natural fluctuations in the ocean temperature in the North Atlantic have a significant impact on the climate in the northern hemisphere. These fluctuations are the result of a complex dance between the forces of nature, but researchers at Aarhus University can now show that solar activity and the impact of volcanic eruptions have led this dance during the last two centuries. Imagine a ballroom in which two dancers apparently keep in time to...

Reimagining How Earth Emerged Out Of Ice Age
2014-03-19 14:15:38

Lee Rannals for redOrbit.com - Your Universe Online Researchers, publishing a paper in the journal Nature, say rapid erosion in mountain regions could explain why the Earth isn’t essentially still a snowball. Scientists have long believed that rocks pushed up to the surface by plate tectonics absorbed atmospheric carbon dioxide, and volcanic processes are what helps to emit this CO2. However, despite this theory and a variety of other hypotheses being put forward to balance the...

Moss Still Lives After 1500 Years Buried In Antarctic Ice
2014-03-17 14:57:18

Brett Smith for redOrbit.com - Your Universe Online British researchers who typically study polar moss samples because they provide indications of past climate conditions have found that Antarctic moss can survive trapped under ice for over 1,500 years. While some plant material has been brought back to life after 20 years of being frozen, only microbes have been shown to be capable of thousand-year feats of revival; that is until now. "These mosses were basically in a very long-term...

Ice Age Flora And Fauna May Have Relied On Volcanic Heat To Thrive
2014-03-12 05:43:40

redOrbit Staff & Wire Reports - Your Universe Online Several types of plants and animals were able to survive ice ages of the past thanks to the heat and steam produced by volcanoes, according to research appearing in a recent edition of the Proceedings of the National Academy of Sciences (PNAS). Dr. Ceridwen Fraser of the Australian National University, Dr. Aleks Terauds from the Australian Antarctic Division and their colleagues said that their research has helped solve a...

Peru Ice Cap Shrinking Due To Warming Temps, Not Less Snowfall
2014-02-26 12:56:35

Brett Smith for redOrbit.com - Your Universe Online When we think about how climate change is shrinking glaciers around the world – we are probably imagining the massive sheets of ice around the Earth’s polar regions. However, glaciers do exist in tropical latitudes, albeit at extremely high elevations, and a new study in the journal Geology has found that one of these tropical glaciers is shrinking as a result of warming temperatures – not lower snowfall levels as some scientists...

Arctic Ocean
2013-04-18 22:31:23

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...
