Understanding the impact of natural atmospheric particles

An international team of scientists, led by the University of Leeds, has quantified the relationship between natural sources of particles in the atmosphere and climate change.

Their study, published today in Nature Geoscience, shows that the cooling effect of natural atmospheric particles is greater during warmer years and could therefore slightly reduce the amount that temperatures rise as a result of climate change.  

Particles in the atmosphere can alter Earth’s climate by absorbing or reflecting sunlight. These particles are often produced by human activities, such as from cars and industry, but there are also naturally occurring particles.

The team combined atmospheric measurements with a computer model to map the effects of two natural particle sources: smoke from forest fires and the gases emitted by trees that can stick together to form tiny particles.
