Satellite Measurements of Stratospheric Forest Fire Smoke

by William J. Randel 6 December 20195 December 2019

Intense boreal forest fires in August 2017 caused smoke plumes that reached record levels in the stratosphere; satellite measurements show that the effects rivaled a moderate volcanic eruption.

Did a Volcanic Eruption in 1783 Change the Climate in Europe?

by David Shultz 17 May 2019

A new model of the Laki eruption in Iceland suggests that normal climate variability was to blame for the anomalously warm summer.

Black Carbon Not the Primary Cause of Historic Glacial Retreat

by Katherine Kornei 16 November 2018

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.

Air Pollutant Plays Lesser Role in Climate Change Than Expected

by L. Joel 26 October 201628 November 2016

Satellite data indicate that pollution control efforts that curbed levels of sulfur dioxide gas did not cause a major decrease in carbon dioxide absorption by plants.

Fewer Tropical Cyclones Form After Volcanic Eruptions

by C. Sullivan 24 February 201624 February 2016

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.

Volcanic Eruptions Steer Conversations on Climate Intervention

by JoAnna Wendel 18 February 20157 September 2016

Studies of volcanoes, Earth's natural climate coolers, cause scientists to question the merits of methods that intend to slow down climate change by injecting the stratosphere with aerosols.
