Do Volcanic Eruptions Ease Global Warming?

Small volcanic eruptions account for part of the global warming slowdown since 2000, a new study suggests.

Until now, the climate impacts of small volcanic blasts were overlooked because their planet-cooling particles cluster below the reach of satellites, scientists reported Oct. 31 in the journal Geophysical Research Letters. It turns out, satellites were missing about 30 percent of these particles, called aerosols, the study found.
