Arctic Amplification Has Reduced Risk Of Extreme Cold Weather
2014-06-16 04:41:53

redOrbit Staff & Wire Reports - Your Universe Online Despite the fact that many parts of the United States experienced extremely cold conditions this past winter, the risk of such conditions increasing as a result of climate change is unlikely, according to research appearing in the latest edition of Nature Climate Change. Study author Dr. James Screen of the University of Exeter reports that the Arctic amplification phenomenon, which refers to the increased warming rate experienced...

Does Solar Activity Have Influence On Earth's Global Warming?
2014-06-06 03:12:26

Science China Press A recent study demonstrates the existence of significant resonance cycles and high correlations between solar activity and the Earth's averaged surface temperature during centuries. This provides a new clue to reveal the phenomenon of global warming in recent years. Their work, entitled "Periodicities of solar activity and the surface temperature variation of the Earth and their correlations" was published in CHINESE SCIENCE BULLETIN (In Chinese) 2014 No.14 with the...

explaining the Last Glacial Maximum
2014-06-03 05:48:44

redOrbit Staff & Wire Reports - Your Universe Online A team of MIT scientists has turned to the Southern Ocean in search of an explanation for the Last Glacial Maximum (LGM), a period in the Earth's climate history during which the northern continents were covered by ice sheets, according to new research appearing in the Proceedings of the National Academy of Sciences. Plankton fossils in deep-sea sediments contain chemical traces that reveal rearranged ocean water masses, as well...

Alan McStravick for redOrbit.com - Your Universe Online This week has certainly been heavy on extinction news. Seth Borenstein's enlightening AP article is one, detailing that the Earth may, in fact, be on the brink of the Sixth Great Extinction event. Citing the loss of species at a rate of 1,000 times faster than at any time prior to the rise of the human race, Borenstein's story states we are toying with disaster and whether or not humans make it out of this alive depends fully on...

Antarctic Ice Sheet Became Unstable At The End Of The Last Ice Age
2014-05-29 05:20:26

redOrbit Staff & Wire Reports - Your Universe Online The Antarctic Ice Sheet started melting approximately 5,000 years earlier than previously believed following the last ice age, according to new research appearing in this week’s edition of the journal Nature. The study, which comes in the wake of research suggesting that destabilization of some of the West Antarctic Ice Sheet has already begun, also said that the shrinkage of the ice sheet accelerated and caused rapid sea level...

Unclouding Our View Of Future Climate

[ Watch The Video: Atmospheric General Circulation Changes Due To Increased Greenhouse Gases ] Carol Rasmussen, NASA's Jet Propulsion Laboratory If we had a second Earth, we could experiment with its atmosphere to see how increased levels of greenhouse gases would change it, without the risks that come with performing such an experiment. Since we don’t, scientists use global climate models. In the virtual Earths of the models, interlocking mathematical equations take the place...

Dr. Ross McKitrick addressed a packed house in Calgary as he walked the audience through the policy implications of the ongoing “pause” in global warming in which climate models continue to overestimate warming when compared to real world data. Economic models are set to match climate models, so they too overestimate the effect of carbon dioxide emissions; these discrepancies will be resolved in the next few years, he explained. Calgary, Alberta, Canada (PRWEB) May 15, 2014 Friends of...

Study Questions Younger Dryas Event Comet Theories
2014-05-14 07:31:39

April Flowers for redOrbit.com – Your Universe Online Approximately 128,000 years ago, near the end of the last Ice Age, there was a brief episode of glacial conditions called the Younger Dryas event. The Younger Dryas, named for a flower that flourished during this time, lasted about 1,000 years. There has been quite a bit of controversy in the scientific community regarding what might have initiated the event—with a wide range of theories, including one that has the event caused by...

Southern Ocean Winds Keep Antarctica Cold And Australia Dry
2014-05-12 03:02:49

[ Watch The Video: Southern Ocean Winds Keep Antarctica Cool, Australia Dry ] Australian National University New Australian National University-led research has explained why Antarctica is not warming as much as other continents, and why southern Australia is recording more droughts. Researchers have found rising levels of carbon dioxide in the atmosphere are strengthening the stormy Southern Ocean winds which deliver rain to southern Australia, but pushing them further south...

Friends of Science are questioning why the National Climate Assessment report does not incorporate the Sept. 27, 2013 acknowledgement by the Intergovernmental Panel on Climate Change (IPCC) of a 15+ year hiatus in global warming - despite a rise in carbon dioxide - and the lack of references to the Technical Uncertainties of that Working Group III report which state low confidence of weather extremes. Friends of Science point to the cyclical nature of the solar magnetic flux as the main...

Climate Change
2013-04-01 11:05:27

Climate change is a substantial and lasting change in the statistical distribution of weather patterns over periods of time ranging from decades to millions of years. It might be a change in the average weather conditions, or in the distribution of weather around the average conditions. Climate change is a result of factors that include oceanic processes, biotic processes, variations in solar radiation received buy Earth, volcanic eruptions, and plate tectonics, and human induced alterations...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...
