Can light-colored rooftops and roads really curb carbon emissions and combat global climate change? The idea has been around for years, but now, a new study by researchers at Lawrence Berkeley National Laboratory that is the first to use a global model to study the question has found that implementing cool roofs and cool pavements in cities around the world can not only help cities stay cooler, they can also cool the world, with the potential of canceling the heating effect of up to two years of worldwide carbon dioxide emissions.

Pitt-Based Researchers Devise Technique to Predict Dust Storms With Infrared Satellite, Shows Potential for Global Monitoring
|
|
09/10/2010 02:44 PM
|
|
Researchers based at the University of Pittsburgh have developed a method for predicting dust and sandstorms that uses infrared satellite images to determine when conditions are ripe for the destructive phenomena, a technique that could be implemented globally and that the research team used to forecast a 2008 New Mexico dust storm-the area's largest in decades-two days beforehand.

Decades of research show massive Arctic ice cap is shrinking
|
|

|
|
Close to 50 years of data show the Devon Island ice cap, one of the largest ice masses in the Canadian High Arctic, is thinning and shrinking. (2010-04-13)

Black Carbon a Significant Factor in Melting of Himalayan Glaciers
|
|
09/10/2010 02:44 PM
|
|
The fact that glaciers in the Himalayan mountains are thinning is not disputed. However, few researchers have attempted to rigorously examine and quantify the causes. Lawrence Berkeley National Laboratory scientist Surabi Menon set out to isolate the impacts of the most commonly blamed culprit-greenhouse gases, such as carbon dioxide-from other particles in the air that may be causing the melting.

Black carbon deposits on Himalayan ice threaten Earth's 'Third Pole'

|
|
Black soot deposited on Tibetan glaciers has contributed significantly to the retreat of the world's largest non-polar ice masses, according to new research by scientists from NASA and the Chinese Academy of Sciences. Soot absorbs incoming solar radiation and can speed glacial melting when deposited on snow in sufficient quantities. (2009-12-15)

Geoengineering: The promise and its limits
|

09/10/2010 02:44 PM
|
|
Four expert speakers attended an event organised by the Institute of Physics, the Royal Society of Chemistry and the Royal Academy of Engineering on 15 July, at the House of Commons, to address an audience curious about geo-engineering the planet to combat the effects of global warming; the solutions it offers and the concerns it raises.

Biosphere 2 experiment shows how fast heat could kill drought-stressed trees
|
|

|
|
Widespread die-off of piñon pine across the southwestern United States during future droughts will occur at least five times faster if climate warms by 4 degrees Celsius, even if future droughts are no worse than droughts of the past century, scientists have discovered in experiments conducted at the University of Arizona's Biosphere 2.

No quick or easy technological fix for climate change, researchers say
|
|
09/10/2010 02:44 PM
|
|
Global warming, some have argued, can be reversed with a large-scale "geoengineering" fix, such as having a giant blimp spray liquefied sulfur dioxide in the stratosphere or building tens of millions of chemical filter systems in the atmosphere to filter out carbon dioxide. (2008-12-18)

Ecologists and oceanographers are attempting to predict the future impacts of climate change by reconstructing the past behavior of Arctic climate and ocean circulation. (2008-11-07)

IMPACTS: On the Threshold of Abrupt Climate Changes
|
|
09/10/2010 02:44 PM
|
|
Abrupt climate change is a potential menace that hasn't received much attention. That's about to change. Through its Climate Change Prediction Program, the U.S. Department of Energy's Office of Biological and Environmental Research (OBER) recently launched IMPACTS - Investigation of the Magnitudes and Probabilities of Abrupt Climate Transitions - a program led by William Collins of Berkeley Lab's Earth Sciences Division (ESD) that brings together six national laboratories to attack the problem of abrupt climate change, or ACC.

|

New research shows that industrial development in North America between 1850 and 1950 greatly increased the amount of black carbon--commonly known as soot-- that fell on Greenland's glaciers and ice sheets. (2007-08-10)

Trees to offset the carbon footprint?
|
|
09/10/2010 02:44 PM
|
|
How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming. (2007-04-10)
