Climate change by global soot dimming may have killed off the dinosaurs and ammonites

From TOHOKU UNIVERSITY A new hypothesis on the extinction of dinosaurs and ammonites at the end of the Cretaceous Period has been proposed by a research team from Tohoku University and the Japan Meteorological Agency’s Meteorological Research Institute. The researchers believe that massive amounts of stratospheric soot ejected from rocks following the famous Chicxulub asteroid…

Soot at the bottom of a meltpool in Greenland

Current atmospheric models underestimate the dirtiness of Arctic air

From the “we told you so” department, it seems they are just now catching up with observations. Black carbon aerosols–particles of carbon that rise into the atmosphere when biomass, agricultural waste, and fossil fuels are burned in an incomplete way–are important for understanding climate change, as they absorb sunlight, leading to higher atmospheric temperatures, and…


Another alarmist pillar collapses – Greenland melting due to old soot feedback loops and albedo change – not AGW

From the EARTH INSTITUTE AT COLUMBIA UNIVERSITY and the “we told you so time and again at WUWT” department comes this study which not only explains the “insta-melt” in the Summer of 2012, but the ongoing melting that has been incorrectly blamed on CO2, when instead it’s all about older soot embedded in snow coming…
