Unraveling Mystery Of Retreating Glaciers In The Pacific Ocean's Western Tropics
2014-03-14 11:39:06

University of California - Los Angeles Using a cutting-edge research technique, UCLA researchers have reconstructed the temperature history of a region that plays a major role in determining climate around the world. The findings, published online Feb. 27 in the journal Nature Geoscience, will help inform scientists about the processes influencing global warming in the western tropical Pacific Ocean. The study analyzes how much temperatures have increased in the region near...

Decreasing Cloud Cover Could Mean Higher Global Temperatures
2013-12-31 15:41:00

[ Watch the Video: Fewer Clouds Could Mean Hotter Temperatures ] Gerard LeBlond for redorbit.com - Your Universe Online A study by the University of NSW (UNSW) claims that the Earth’s temperatures will rise 7.2 degrees Fahrenheit by the end of the century. Earlier predictions that were based on cloud cover forecast a smaller increase and were most likely wrong, according to the study, to be published January 1, 2014 in the journal Nature. This could mean catastrophic results for...

Sun's Increasing Brightness Will Dry Out The Earth In A Billion Years
2013-12-17 04:36:50

[ Watch the Video: The Sun Will Evaporate Our Oceans Eventually ] Ranjini Raghunath for redOrbit.com - Your Universe Online One billion years from now, all the water on Earth could disappear, making it barren like Venus, and the culprit isn’t climate change. It’s the Sun, according to a new study published in the journal Nature. Scientists have previously predicted that, even without climate change, the Earth’s surface would still heat up, because of the Sun’s increasing...

First comprehensive survey shows 60 percent rise over last 30 years of floods, droughts and storms Europe needs to plan for future probabilities of extreme weather. Heat waves, floods and storms do not respect national frontiers, so there is a need for action at both national and EU levels. The IPCC has advised that the frequency of many types of extreme weather events will continue to grow globally in coming years. Now the national science academies of EU Member States bring into focus...

Pollution Causes Thunderstorms To Leave Lingering Clouds
2013-11-26 15:18:22

Pacific Northwest National Laboratory Study shows why pollution results in larger, deeper and longer lasting storm clouds, leading to colder days and warmer nights A new study reveals how pollution causes thunderstorms to leave behind larger, deeper, longer lasting clouds. Appearing in the Proceedings of the National Academy of Sciences November 26, the results solve a long-standing debate and reveal how pollution plays into climate warming. The work can also provide a gauge for the...

Climate Science Boost With Tropical Aerosols Profile
2013-08-02 12:59:57

CSIRO The seasonal influence of aerosols on Australia's tropical climate can now be included in climate models following completion of the first long-term study of fine smoke particles generated by burning of the savanna open woodland and grassland. Australia's biomass burning emissions comprise about eight per cent of the global total, ranking third by continent behind Africa (48 per cent) and South America (27 per cent). Lead researcher, CSIRO's Dr Ross Mitchell, said fine particles...

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...

Greenland Ice Sheet Had Record Melt In 2012 Due To Jet Stream
2013-06-17 13:50:43

Lee Rannals for redOrbit.com — Your Universe Online According to University of Sheffield research, published in the International Journal of Climatology, unusual Jet Stream changes were behind record surface melt of the Greenland Ice Sheet last summer. The Greenland Ice Sheet (GrIS) experienced a record surface melting in the summer of 2012, with more than 90 percent of the ice-sheet surface melting as of July 11, 2012. That was nearly double the previous record loss seen in 2010,...
