Of all the factors that influence Earth's changing climate, the effect that tiny particles in Earth's atmosphere called aerosols have on clouds is the least well understood.
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.
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 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.
Imagine a world where the rooftops and pavements of every urban area are resurfaced to increase the reflection of the Sun's light rays.
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.
Scientists from 20 institutions around the world said that the impact of deforestation on global warming varies with latitude.
The Greenland ice sheet can experience extreme melting even when temperatures don’t hit record highs, according to a new analysis.
