Nature World: Small volcanic eruptions over the years may actually helped slow climate change. That's at least according to a new study which details how minor eruptions between 200 and 2013 may have directly cooled the average global temperature.
The study, published in the journal Geophysical Research Letters, describes how volcanoes blast helpful particles, called aerosols, into the air during an eruption. When these sulfer dioxide aerosols reach the stratosphere (the second layer of our atmosphere), they...
