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,...

Manhattan Heat-Related Deaths Expected To Increase
2013-05-20 05:20:42

redOrbit Staff & Wire Reports - Your Universe Online Increasing temperatures could cause heat-related deaths in Manhattan to increase by one-fifth by the end of the decade, and nearly double before the end of the century, according to new research published in this week´s edition of the journal Nature Climate Change. In the study, scientists from the Columbia University's Earth Institute and the Mailman School of Public Health report that deaths related to global warming could...

The Bureau of Reclamation and collaborators developed new downscaled climate projections that allow water managers to incorporate the new Coupled Model Inter-comparison Project Phase 5 data from the World Climate Research Program into their water management planning. The data, representing 234 contemporary climate projections for the contiguous United States, was downscaled to a 12 kilometer resolution in order to be more useful to water managers. Washington, D.C. (PRWEB) May 09, 2013 The...

Greenland's 2012 Record Ice Melt Due To Thin Cloud Cover
2013-04-04 11:15:46

April Flowers for redOrbit.com - Your Universe Online Global sea levels would rise by 24 feet if the sheet of ice covering Greenland were to melt in its entirety tomorrow. But it is very unlikely that nearly two million cubic miles of ice will wash into the ocean overnight. Researchers have been tracking increasing melt rates since 1979. Last summer the melt was so extensive that ice core records show similar events only about once every 150 years over the last four millennia. "In...

Antarctic Cloud Cover Caused Glitch In Tropical Rainfall Model
2013-03-12 10:46:10

April Flowers for redOrbit.com - Your Universe Online One would not assume that cloud cover over Antactica's Southern Ocean could cause rainfall in Zambia or the tropical island of Java. New research from the University of Washington, however, finds that a phantom band of rainfall just south of the equator that does not occur in reality is caused by poor simulation of the cloud cover thousands of miles farther to the south. This illusionary band of rainfall is one of the most persistent...

Rainforests May Be Resilient To Climate Change
2013-03-11 04:51:35

redOrbit Staff & Wire Reports - Your Universe Online Tropical forests may be more resistant to the effects of greenhouse gas emissions than previously believed, according to a new study published online this week in the journal Nature Geoscience. In what Olive Heffernan of Nature refers to as “the most extensive study of its kind,” researchers from the US, the UK, Australia and Brazil created a simulation of the impact that carbon-based emissions would have on tropical...

Winters Will Be Warmer And Wetter In The Northeast By 2070
2012-12-13 11:01:04

April Flowers for redOrbit.com - Your Universe Online A team of climate scientists from the University of Massachusetts Amherst has released a new study suggesting temperatures are going to be significantly warmer in all seasons in the next 30 years, especially in winter. The study, published in the current issue of the Journal of Geophysical Research, is the first to apply regional climate models to examine likely near-term changes in temperature and precipitation across the...

Greenland Could Be Affected By Warming Temperatures
2012-11-14 09:01:27

April Flowers for redOrbit.com - Your Universe Online There are almost as many global climate models as there are climate scientists. Even with all of these models, however, it's very difficult to pin down how warming temperatures globally will affect any specific region. A research team from The City College of New York and the University of Liege, Belgium, and supported by the National Science Foundation (NSF), have made the "global local" using the output of three global models and...
