Insufficient Forcing Uncertainty

It seems depending on who you talk to, climate sensitivity is either underestimated or overestimated. In this case, a model suggests forcing is underestimated. One thing is clear, science does…

CO2, Soot, Modeling and Climate Sensitivity

Warming Caused by Soot, Not CO2 From the Resilient Earth Submitted by Doug L. Hoffman on Wed, 07/15/2009 – 13:19 A new paper in Science reports that a careful study…

"There appears to be something fundamentally wrong with the way temperature and carbon are linked in climate models."

From e! sciencenews Global warming: Our best guess is likely wrong Published: Tuesday, July 14, 2009 – 11:45 in Earth & Climate Rice University/Photos.com No one knows exactly how much Earth’s…

Climate projections: Past performance no guarantee of future skill?

Forecasting accuracy of Global Climate Models is something that has been at the very heart of the global warming debate for some time. Leif Svalgaard turned me on to this…

Quote Of The Week #13

From Gary Strand, software engineer at the National Center for Atmospheric Research (NCAR) commenting on Climate Audit: As a software engineer, I know that climate model software doesn’t meet the…

Common Sense and The Perils of Predictions

Guest essay by Michael R. Smith, C.C.M. Forbes, “Absolute Return” column, April 21, 2008, page 246: Here’s another name you should own, Freddie Mac ($29 per share)…Freddie is cheap at…

Suggestions of "strong negative cloud feedbacks" in a warmer climate

I thought this post on clouds and climate modeling below from Steve McIntyre’s Climate Audit was interesting, because it highlights the dreaded “negative feedbacks” that many climate modelers say don’t…

MIT: Global Warming of 7°C 'Could Kill Billions This Century'

By Steven Goddard Some readers may remember the 1961 film “The Day the Earth Caught Fire”. It could be viewed as the original “climate alarmist” film as it contains all…

Uh, oh. 50 year old ocean thermohaline model sinking fast, climate models may be disrupted

Another “observations are not models” story is emerging. For more on the status quo of thermohaline circulation, see this Wiki  article – Anthony Deep Ocean Conveyor Belt Reconsidered From Peter…

Spencer on an alternate view of CO2 increases

This interesting essay by Dr. Spencer is reposted from his blog, link here: Global Warming Causing Carbon Dioxide Increases: A Simple Model May 11th, 2009 by Roy W. Spencer, Ph.…

The Global Warming Hypothesis and Ocean Heat

Guest Post By William DiPuccio Albert Einstein once said, “No amount of experimentation can ever prove me right; a single experiment can prove me wrong.”  Einstein’s words express a foundational…

Climate Models -vs- Climate Reality: diverging or just a dip?

Here’s something really interesting:  two comparisons between model ensembles and  3 well known global climate metrics plotted together. The interesting part is what happens in the near present. While the…

Lindzen on negative climate feedback

NEW 4/10/09: There is an update to this post, see below the “read the rest of this entry” – Anthony Guest Post by Richard Lindzen, PhD. Alfred P. Sloan Professor…

Dr. Roy Spencer on publishing and climate sensitivity

Set Phasers on Stun March 29th, 2009 by Roy W. Spencer, Ph. D. I’ve been receiving a steady stream of e-mails asking when our latest work on feedbacks in the…

If You Can't Explain It, You Can't Model It

Guest Post by Steven Goddard Global Climate Models (GCM’s)  are very complex computer models containing millions of lines of code, which attempt to model cosmic, atmospheric and oceanic processes that…

Short term trends from GISS Model E: "The model would be off by about 0.15C in the first five years"

On occasion, comments posted on WUWT are backed up with data or graphs from the commenter, and are so germane that they merit their own post for discussion. This is…

When You Can’t Believe the Model

This article was sent to me by reader Peter Yodis. I found it interesting and germane to current events, so I’m sharing it here. Just a note for clarification, the…
