Study Highlights Complex Interplay Between Global Warming And Rainfall
2013-01-31 09:51:24

April Flowers for redOrbit.com - Your Universe Online An international group of scientists has shown that global warming from greenhouse gases affects global rainfall patterns differently than global warming from solar heating. Using computer model simulations, the research team showed that global rainfall has increased less over the present-day warming period than during the Medieval Warm Period between 950 and 1250 AD despite the fact that temperatures today are higher than...

Climate scientists are still grappling with one of the main questions of modern times: how high will global temperatures rise if the atmospheric concentration of carbon dioxide doubles. Many researchers are now turning to the past because it holds clues to how nature reacted to climate change before the anthropogenic impact. The divergent results of this research, however, have made it difficult to make precise predictions about the impact of increased carbon dioxide on future warming. An...

At the end of the 21st century, the temperature in the Baltic Sea will be higher and the salt content lower than at any time since 1850. If no action is taken to alleviate the effects of climate change, there may be major consequences for the marine environment. "This is the first time that anyone has taken a detailed look at how climate models and individual factors combine to affect a specific region. This makes this project unique," says Jonathan Havenhand from the Department of...

Climate Models Work For Mars Too
2012-10-17 10:56:49

Lee Rannals for redOrbit.com - Your Universe Online According to a new study, scientific modeling methods that predicated climate change on Earth can also be used on Mars as well. Researchers from Planetary Science Institute in Tucson report they have found that an unusual concentration of glacial features on Mars matches predictions made by global climate computerized models, in terms of age and location. "Some public figures imply that modeling of global climate change on Earth is...

MAGIC Launches For Yearlong Climate Study

Climate instruments mounted aboard the Horizon Spirit container ship begin taking data A Horizon Lines container ship outfitted with meteorological and atmospheric instruments installed by U.S. Department of Energy (DOE) scientists from Argonne National Laboratory and Brookhaven National Laboratory will begin taking data today for a yearlong mission aimed at improving the representation of clouds in climate models. The study, a collaborative effort between DOE´s Atmospheric Radiation...

Space Mirrors Won't Fix Climate Change
2012-06-06 12:00:59

Michael Crumbliss for redOrbit.com Geoengineering is a field of study that proposes techniques to reduce the amount of solar radiation reaching the Earth's surface. Methods range from mimicking the effects of large volcanic eruptions by releasing sulphur dioxide into the atmosphere to deploying giant mirrors in space. Scientists have proposed these sunlight-reflecting solutions as last-ditch attempts to halt global warming. A new study used climate models developed by the UK Met...

One popular climate record that shows a slower atmospheric warming trend than other studies contains a data calibration problem, and when the problem is corrected the results fall in line with other records and climate models, according to a new University of Washington study. The finding is important because it helps confirm that models that simulate global warming agree with observations, said Stephen Po-Chedley, a UW graduate student in atmospheric sciences who wrote the paper with...

On the hottest day of the New York City summer in 2011, a white roof covering was measured at 42 degrees Fahrenheit cooler than the traditional black roof it was being compared to, according to a study including NASA scientists that details the first scientific results from the city's unprecedented effort to brighten rooftops and reduce its "urban heat island" effect. The dark, sunlight-absorbing surfaces of some New York City roofs reached 170 degrees Fahrenheit on July 22, 2011, a day...

The instant communications technology that nurtured grassroots revolutions in the Arab world could also help farmers cope with climate change, according to Iowa State University researchers. And so the researchers — Steven Fales, a professor of agronomy; and Gene Takle, director of Iowa State's Climate Science Program, a professor of agronomy and of geological and atmospheric sciences — are organizing a symposium to explore that idea during the annual meeting of the American...

Image 1 - Human Activity, Not Solar Activity, Drives Global Warming
2012-02-01 05:11:53

A new NASA study underscores the fact that greenhouse gases generated by human activity -- not changes in solar activity -- are the primary force driving global warming. The study offers an updated calculation of the Earth's energy imbalance, the difference between the amount of solar energy absorbed by Earth's surface and the amount returned to space as heat. The researchers' calculations show that, despite unusually low solar activity between 2005 and 2010, the planet continued to absorb...
