Large Volcanic Eruptions Affect the "Greener Greenhouse"

Last year, scientists discovered that the northern hemisphere was becoming increasingly greener due to increased warming. Furthering that study, researchers have discovered that tremendous amounts of tiny pollutant particles thrust into the atmosphere by large volcanic eruptions slow plant growth, but still enhance the ability of lands to act as a sink for carbon, as reported in the May 31st issue of Science.
