GEOS-5 Provides Portrait of Global Winds
2013-11-21 10:03:41

NASA High-resolution global atmospheric modeling provides a unique tool to study the role of weather within Earth’s climate system. NASA’s Goddard Earth Observing System Model (GEOS-5) is capable of simulating worldwide weather at resolutions as fine as 3.5 kilometers. This visualization shows global winds from a GEOS-5 simulation using 10-kilometer resolution. Surface winds (0 to 40 meters/second) are shown in white and trace features including Atlantic and Pacific cyclones....

A new Friends of Science study by research director Ken Gregory shows that the Canadian climate model CanESM2, used by the Intergovernmental Panel on Climate Change (IPCC) to predict global warming, fails to replicate temperature observations by hundreds of percent – predicting extreme heat when the reality observed is only nominal warming. Calgary, Alberta (PRWEB) October 31, 2013 Friends of Science have released a new in-depth study of the predictive climate models of the Canadian...

Climate Models Help Researchers Understand Atmospheric Electricity
2013-10-04 08:51:04

April Flowers for redOrbit.com - Your Universe Online A detectable electrification of the air is caused by electrical currents born from thunderstorms. These currents flow through the atmosphere around the globe, even in places with no thunderstorm activity. Until recently, however, science has not had a good explanation for how conductivity varies throughout the atmosphere and how that may affect the path of the electrical currents. A new study led by the University of Colorado...

Satellites Providing Information On Earth’s Albedo With Remarkable Accuracy
2013-09-06 11:48:30

[ Watch The Video - Reflecting Power Of Earth’s Albedo ] ESA The amount of sunlight being absorbed or reflected by Earth is one of the driving forces for weather and climate. Satellites are providing this information with unprecedented accuracy. The reflecting power of a surface is known as ‘albedo’. Bright snow and ice have a high albedo, meaning they reflect solar radiation back into space, while green areas like forests and fields have a much lower albedo. The lower the...

Global Warming Increases Risk Of Record Heat
2013-09-06 04:50:27

redOrbit Staff & Wire Reports - Your Universe Online Last July was the hottest month in the history of US weather record keeping, but it may not hold that title for long, researchers from Stanford University claim in a recently-published report. According to Noah Diffenbaugh, an associate professor of environmental Earth system science at the California institution, and research assistant Martin Scherer, extreme weather is more than four times more likely to occur now than it was...

Early Earth Relied On Carbon To Keep Warm Enough For Life
2013-07-10 13:58:57

Lee Rannals for redOrbit.com - Your Universe Online University of Colorado Boulder researchers have figured out how early Earth was warm enough to support life when the sun was 20 per cent dimmer than today. A new study determined that all that may have been required to sustain liquid water and primitive life on Earth during the Archean eon, 2.8 billion years ago, were the reasonable atmospheric carbon dioxide amounts believed to be present at the time and a little bit of methane....

Climate Changes Could Increase Hurricane Frequency This Century
2013-07-09 11:21:34

Brett Smith for redOrbit.com - Your Universe Online Using a unique combination of computer models, MIT atmospheric scientist Kerry Emanuel has made the contested prediction the 21st century will see an uptick in the number of hurricanes and tropical storms as a result of the forces of climate change. "Studies using the same technique applied to the previous generation of global climate models showed very little change in global frequency, but an increase in intensity," Emanuel told...

Managing Future Of Colorado River Flows
2013-06-25 13:09:31

University of Washington The Colorado River provides water for more than 30 million people, including those in the fast-growing cities of Las Vegas, Phoenix and Los Angeles. Increasing demand for that water combined with reduced flow and the looming threat of climate change have prompted concern about how to manage the basin’s water in coming decades. In the past five years, scientific studies estimated declines of future flows ranging from 6 percent to 45 percent by 2050. A paper by...

Warming In China Four Times Greater Than Previously Thought
2013-05-15 15:31:28

Brett Smith for redOrbit.com - Your Universe Online According to new research in the Proceedings of the National Academy of Sciences (PNAS), average temperatures in central China are 10 to 14 degrees Fahrenheit hotter today than they were during the last Ice Age 20,000 years ago. The authors of the study predict that these findings, which are two to four times greater than previous models have shown, could help researchers build up more precise models of previous climate change patterns...


Word of the Day
abrosia
  • Wasting away as a result of abstinence from food.
The word 'abrosia' comes from a Greek roots meaning 'not' and 'eating'.
