Claim: Global Warming will Impede Volcanic Cooling

Guest essay by Eric Worrall A study published in the Journal of Geophysical Research claims that global warming will impede the ability of volcanoes to push sulphur compounds into the stratosphere, which will in turn reduce the cooling effect of volcanic eruptions. Climate change may prevent volcanoes from cooling the planet … When an eruption…

Volcanic Legends Keep Erupting

Guest Post by Willis Eschenbach Once again, Anthony has highlighted a paper claiming that volcanoes have great power over the global temperature. Indeed, they go so far as to say:  From the reconstruction it can be seen that large eruptions, such as Mount Tambora in 1815, or clusters of eruptions, may result in a hiatus of…

Volcanoes and Sunspots

Guest Post by Willis Eschenbach I keep reading how sunspots are supposed to affect volcanoes. In the comments to my last post, Tides, Earthquakes, and Volcanoes, someone approvingly quoted a volcano researcher who had looked at eleven eruptions of a particular type and stated: …. Nine of the 11 events occurred during the solar inactive phase…

Tides, Earthquakes, and Volcanoes

Guest Post by Willis Eschenbach [Graphs updated to include error bars] Inspired by the paper by the charmingly-named Maya Tolstoy discussed here on WUWT, I decided to see if tidal forces affect the timing of earthquakes and volcanoes. Dr. Tolstoy’s hypothesis is that tidal forces affect the timing of the subterranean eruptions … but she has…

Volcanoes Once Again, Again

Guest Post by Willis Eschenbach [also, see update at the end of the post] Anthony recently highlighted a couple of new papers claiming to explain the current plateau in global warming. This time, it’s volcanoes, but the claim this time is that it’s not the big volcanoes. It’s the small volcanoes. The studies both seem to…

Volcanoes and Drought In Asia

Guest Post by Willis Eschenbach There’s a recent study in AGU Atmospheres entitled “Proxy evidence for China’s monsoon precipitation response to volcanic aerosols over the past seven centuries”, by Zhou et al, paywalled here. The study was highlighted by Anthony here. It makes the claim that volcanic eruptions cause droughts in China. Is this possible?…
