Reduction in Amazon deforestation avoids 1,700 deaths per year

Because of decreasing deforestation and emissions from forest fires in the Amazon over the past ten years, the amount of particulate matter (aerosols), ozone, carbon monoxide, nitrogen oxide and other atmospheric pollutants ...

Dust from the Sahara Desert cools the Iberian Peninsula

Spanish and Portuguese researchers have analysed the composition and radiative effect of desert aerosols during two episodes which simultaneously affected Badajoz (Spain) and Évora (Portugal) in August 2012. Results show ...

Image: Measuring clouds and aerosols from the space station

Clouds can be observed from the International Space Station moving across Earth's surface, as in this image of New Zealand taken by Expedition 42 Flight Engineer Samantha Cristoforetti. Other tiny solid and liquid particles ...

NASA's CATS eyes clouds, smoke and dust from the space station

Turn on any local TV weather forecast and you can get a map of where skies are blue or cloudy. But for scientists trying to figure out how clouds affect the Earth's environment, what's happening inside that shifting cloud ...

New technology tracks tiniest pollutants in real time

Researchers may soon have a better idea of how tiny particles of pollution are formed in the atmosphere. These particles, called aerosols, or particulate matter (PM), are hazardous to human health and contribute to climate ...

CLOUD sees through the haze

The CLOUD (Cosmic Leaving OUtdoor Droplets) experiment at CERN, which is studying whether cosmic rays have a climatically significant effect on aerosols and clouds, is also tackling one of the most challenging problems in ...

Famous paintings help study the Earth's past atmosphere

A team of Greek and German researchers has shown that the colours of sunsets painted by famous artists can be used to estimate pollution levels in the Earth's past atmosphere. In particular, the paintings reveal that ash ...

Aerosols appear to weaken hurricanes

Aerosols in the atmosphere produced from human activities do indeed directly affect a hurricane or tropical cyclone, but not in a way many scientists had previously believed – in fact, they tend to weaken such storms, according ...

Brown carbon works both sides of the climate equation

There is an atmospheric particle not satisfied with only a single role in the climate. The ambitious culprit? Brown carbon aerosol steps outside the box and acts to both warm and cool the climate. A brown secondary organic ...
