Using the Orbiting Carbon Observatory for something useful: monitoring potential volcanic eruptions

From MICHIGAN TECHNOLOGICAL UNIVERSITY Is it gonna blow? Measuring volcanic emissions from space Late last month, a stratovolcano in Bali named Mount Agung began to smoke. Little earthquakes trembled beneath the mountain. Officials have since evacuated thousands of people to prevent what happened when Agung erupted in 1963, killing more than 1,000 people. Before volcanoes erupt,…

Volcanic Northern Winters

I see there’s a new study, unfortunately paywalled, which starts out by saying: Observations show that all recent large tropical volcanic eruptions (1850-present) were followed by surface winter warming in the first Northern Hemisphere (NH) winter after the eruption. Recent studies show that climate models produce a surface winter warming response in the first winter…
