More aerosol particles than thought are forming over Siberia, finds study
Aerosol particles play a key role in cooling the planet. They can either directly affect how much sunlight ends up on the surface of the Earth or indirectly through cloud formation, to which they contribute. New particles form from a variety of gas m.....»»
The first assessment of toxic heavy metal pollution in the Southern Hemisphere over the last 2,000 years
Human activity, from burning fossil fuels and fireplaces to the contaminated dust produced by mining, alters Earth's atmosphere in countless ways. Records of these impacts over time are preserved in everlasting polar ice that serves as a sort of time.....»»
