Black Carbon Not the Primary Cause of Historic Glacial Retreat
Ice cores and glacial records reveal that European glaciers retreated before the rise of industrialization in the 1870s, suggesting that soot deposition did not primarily drive the shift.

Does Water Vapor from Volcanic Eruptions Cause Climate Warming?
By studying past volcanic eruptions, scientists find that the amount of water vapor reaching the stratosphere during moderately explosive eruptions may not be contributing to the greenhouse effect.

Fewer Tropical Cyclones Form After Volcanic Eruptions
Volcanic eruptions aren't all bad—in some cases, they can lower the frequency of tropical cyclones in the North Atlantic by emitting sulfate aerosols.
