Impact of explosive volcanic eruptions on the main climate variability modes
Volcanic eruptions eject largeamounts of materials into the atmosphere, which can have an impact on climate. In particular, the sulphur dioxide gas released in the stratosphere leads to aerosol formation that reflects part of the incoming solar radiation, thereby affecting the climate energy balance...

Volcanic eruptions eject largeamounts of materials into the atmosphere, which can have an impact on climate.
