‘Climate adaptation, a wicked problem, requires navigating a landscape that is only partly known’

A WUWT reader from NCAR sends this but wishes to remain anonymous. I verified the IP address as coming from NCAR. Bold mine. ============================================================ Hi Mr. Watts, I come to your website nearly every day. Working here at NCAR, we rarely ever get to hear the other side of the CAGW argument, so I greatly…

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…

Another uncertainty for climate models – different results on different computers using the same code

New peer reviewed paper finds the same global forecast model produces different results when run on different computers Did you ever wonder how spaghetti like this is produced and why there is broad disagreement in the output that increases with time? Graph above by Dr. Roy Spencer Increasing mathematical uncertainty from initial starting conditions is…

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…

NCAR says targeting specific pollutants would slow SLR

From the  National Center for Atmospheric Research/University Corporation for Atmospheric Research I can see the EPA jumping all over this one. Black carbon is likely a contributor, as it changes the albedo of ice sheets and one that is much easier to manage. Problem is, the USA isn’t much of a black carbon emitter any…
