Guest post by Kevin Kilty Introduction This short essay was prompted by a recent article regarding improvements to uncertainty in a global mean temperature estimate.[1] However, much bandwidth has been spilt lately in the...

Guest post by Pat Frank My September 7 post describing the recent paper published in Frontiers in Earth Science on GCM physical error analysis attracted a lot of attention, consisting of both support and criticism...

guest post by Nick Stokes There has been a lot of discussion lately of error propagation in climate models, eg here and here. I have spent much of my professional life in computational fluid dynamics, dealing with exactly...

Reposted from Dr. Roy Spencer’s blog September 13th, 2019 by Roy W. Spencer, Ph. D. Have you ever wondered, “How can we predict global average temperature change when we don’t even know what the global average temperature...

From Dr Roy Spencer’s Blog September 12th, 2019 by Roy W. Spencer, Ph. D. NOTE: This post has undergone a few revisions as I try to be more precise in my wording. The latest revision was at 0900 CDT Sept. 12, 2019. If this...

From Dr. Roy Spencer’s Blog September 11th, 2019 by Roy W. Spencer, Ph. D. I’ve been asked for my opinion by several people about this new published paper by Stanford researcher Dr. Patrick Frank. I’ve spent a couple...
