1D Model of Global SST Shows 40% of Warming Since 1979 Due to Early Volcanic Cooling

From Dr. Roy Spencer’s Blog January 14th, 2020 by Roy W. Spencer, Ph. D. In 2017, Christy & McNider published a study where they estimated and removed the volcanic effects from our UAH lower tropospheric (LT) temperature record, finding that 38% of the post-1979 warming trend was due to volcanic cooling early in the record.…

Geoengineering vs. volcanic activity for a cooler climate

[More crazy talk from Carnegie Institute’s Ken Caldiera… Anthony] Washington, DC– Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun’s radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change? A new paper in Geophysical Research Letters investigates. Solar geoengineering is a…

Guess where the biggest volcanic eruption of 2018 was? Hint (not Hawaii)

There have been voluminous headlines, photos, and video describing eruptions on Hawaii’s Kilaueua in 2018, and while they were visually impressive, when it comes to potentially climate altering sulfur dioxide, those eruptions pale in comparison to another Pacific volcano. NASA Earth observatory writes: While Kilauea dominated headlines last year, the largest explosive eruption of 2018…
