The three main factors controlling the behavior and responses of terrestrial ecosystems

ACCC research, Blog, Publications /

Ecosystems provide multiple services. The quality of these services depends, however, on the characteristics of ecosystems and their functioning, which is determined both by natural conditions and factors such as climate, and by interaction with humans. A recent study, published in Nature, has identified three key functions that govern the behavior of ecosystems, and which […]

Observations confirm that aerosols formed from plant emitted compounds can make clouds brighter

ACCC research, Publications, Uncategorized /

An observational study by Finnish research groups confirms a prevailing theory that volatile organic compounds emitted by vegetation form atmospheric aerosols which make clouds more reflective. Brighter clouds reduce the amount of solar radiation reaching the Earth’s surface, thereby cooling the surface. Emissions of organic compounds from vegetation increase with increasing temperature, thus having the
