Claim: Last 100 years may be warmest in 120,000 years in the Arctic, but not so fast (UPDATED)

From the University of Colorado at Boulder, comes this study about radiocarbon dating some dead moss clumps exposed from under ice/snow at 4 locations on Baffin Island that somehow proves “unprecedented” warmth for the entire Arctic for the last 120,000 years. See below for my take on it. CU-Boulder study shows unprecedented warmth in Arctic…

Using a climate model to map global atmospheric conductivity

From the University of Colorado at Boulder CU-Boulder researchers use climate model to better understand electricity in the air Electrical currents born from thunderstorms are able to flow through the atmosphere and around the globe, causing a detectable electrification of the air even in places with no thunderstorm activity. But until recently, scientists have not…

Claim: Faint Young Sun Paradox solved

From the University of Colorado at Boulder a claim that computer modeling has solved the problem, with an atmosphere that is 20,000 parts per million of  CO2 and 1,000 ppm of methane. CU study shows how early Earth kept warm enough to support life Scientists tackle faint young sun paradox with 3-D climate models Solving…
