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.
Humanity’s carbon emissions are, by far, the largest disturbance to Earth’s steady state carbon cycle.
A new model of the Laki eruption in Iceland suggests that normal climate variability was to blame for the anomalously warm summer.
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.
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.
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.
High-Latitude Volcanic Eruption Impacts on Climate: Filling the Gaps; Stockholm, Sweden, 5–7 November 2014
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.
In a study with implications for geoengineering, large Northern Hemispheric volcanic eruptions are found to cause strong droughts in much of eastern China.
