Stacking Up Volcanoes
Guest Post by Willis Eschenbach [See Update at end] As readers of my posts know, I’ve held for many years that there are a variety of emergent phenomena that regulate the earth’s temperature. See my posts The Thermostat Hypothesis and Emergent Climate Phenomena for an overview of my hypothesis. One of the predictions derivable…
When Eruptions Don’t
Guest Post by Willis Eschenbach Inspired by Richard Keen’s interesting WUWT post on using eclipses to determine the clarity of the atmosphere, I went to the website of the Hawaiian Mauna Loa Observatory. They have some very fascinating datasets. One of them is a measurement of direct solar radiation, minute by minute, since about 1980. I…
The effect of volcanoes on climate and climate on volcanoes
by Javier The effect of volcanoes on climate The relationship between volcanoes and climate is a very complex one. From reading the media one gets the impression that they are some sort of climatic wild card. They are used to explain the cooling after the Pinatubo eruption, or the Little Ice Age cooling as a…

Yellowstone Eruption: More Quickly, not Sooner
Arrgh. Three days ago, a New York Times article reported: Yellowstone’s last supereruption occurred 631,000 years ago. And it’s not the planet’s only buried supervolcano. Scientists suspect that a supereruption scars the planet every 100,000 years, causing many to ask when we can next expect such an explosive planet-changing event.

Geologists warn us about dangerous volcanoes. Will we spend pennies for warnings?
By Larry Kummer. From the Fabius Maximus website. Summary: While we obsess about climate change and debate if we live in the Anthropocene, we prepare poorly or not at all for natural forces like volcanoes that can level cities. This is folly we can no longer afford. Experts recommend a simple first step to better…
End-Permian Extinction Due to Contact Metamorphism?
David Middleton Here’s a novel take on the Siberian Traps and the End-Permian extinction: Geology Massive underground magma pulse caused the world’s largest mass-extinction The end-Permian wiped out almost all marine species Geologists have suggested that Earth’s most severe mass-extinction was caused by a huge pulse of magma which released deadly levels of greenhouse gases…
