University of Leeds The first ecological study of an entire glacier has found that microbes drastically reduce surface reflectivity and have a non-negligible impact on the amount of sunlight that is reflected into space. The research, led by the University of Leeds and published June 12 in the journal FEMS Microbiology Ecology, will help improve climate change models that have previously neglected the role of microbes in darkening the Earth's surface. Observing how life thrives at...

For first time, Dartmouth study puts a dollar value on snow's reflection of solar energy Replacing forests with snow-covered meadows may provide greater climatic and economic benefits than if trees are left standing in some regions, according to a Dartmouth College study that for the first time puts a dollar value on snow's ability to reflect the sun's energy. The findings suggest more frequent logging or deforestation may better serve our planet and pocketbooks in high latitude areas...

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...

Lighter colored roofs could offset 150 billion tons of CO2, states Weatherproofing Advisors, Ltd., the UK's leader in Industrial and Commercial Roofing Services. Greenville, SC (PRWEB) May 08, 2013 Weatherproofing Advisors, Ltd. recently recommended that if all roofs worldwide would be painted white, this change could have the equivalent impact on the climate to that of taking all the world´s cars off the road for 50 years. The recommendation is based on the work by Hashem Akbari and...

The influence of aerosols (small particles less than 1 micrometer in diameter) and clouds (liquid droplets 1 — 1000 micrometers diameter) represents one of the largest uncertainties in our understanding of trends in past global climate and predicting future climate change, as recognized by the 2007 report of the Intergovernmental Panel on Climate Change. One of the most significant 'known unknowns' is how quickly water can condense on the small aerosol particles to grow and become...

Imagine a world where the rooftops and pavements of every urban area are resurfaced to increase the reflection of the Sun's light rays. Well, this is exactly what a group of Canadian researchers have done in an attempt to measure the potential effects against global warming. In a study published today, 13 April, in IOP Publishing's journal Environmental Research Letters, researchers from Concordia University created this scenario to see what effect a global increase in surface reflectance...

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...

Impacts Of Deforestation Varies By Latitude
2011-11-17 05:49:49

Scientists from 20 institutions around the world said that the impact of deforestation on global warming varies with latitude. Researchers say these new findings, which were published in the journal Nature, call for new climate-monitoring strategies. "It depends where the deforestation is," UC Davis atmospheric science Professor Kyaw Tha Paw U, a study co-author, said in a press release "It could have some cooling effects at the regional scale, at higher latitudes, but there's no...

Extreme Melting On Greenland Ice Sheet Reported
2011-10-26 03:32:48

Glacial Melt Cycle Could Become Self-Amplifying, Making it Difficult to Halt The Greenland ice sheet can experience extreme melting even when temperatures don´t hit record highs, according to a new analysis by Dr. Marco Tedesco, assistant professor in the Department of Earth and Atmospheric Sciences at The City College of New York.  His findings suggest that glaciers could undergo a self-amplifying cycle of melting and warming that would be difficult to halt. “We are...

“Albedo Effect” In Forests Can Cause Added Warming, Bonus Cooling
2011-10-20 06:10:28

Wildfire, insect outbreaks and hurricanes destroy huge amounts of forest every year and increase the amount of carbon dioxide entering the atmosphere, but scientists are now learning more about another force that can significantly affect their climate impact. Researchers conclude in a new study that the albedo effect, which controls the amount of energy reflected back into space, is important in the climatic significance of several types of major forest disturbances. In some cases...
