Air Quality

Aerosol particles in the air originating from a number of sources, including motor vehicles, industrial processes and forest fires, reduce air quality and can lead to asthma and cardiovascular problems, among other illnesses. The standard method for keeping tabs on the air-polluting particles [...]

Understanding Climate

The amount and type of vegetation found at the Earth's surface--be it forests or agricultural fields--has a significant impact on the interaction between the land and atmosphere, including the absorption of solar energy and the evaporation of water. That interaction influences cloud cover and the [...]

Nothing but Sand

Human encroachment, agriculture, livestock grazing and climate changes have dramatically increased the conversion of fragile grasslands to deserts worldwide. A major impact of desertification is loss of biodiversity and decreased capacity to produce crops. Ironically, droughts are common in these [...]
