Our current weather: A test for forecast models – December shaping up to be one of the coldest on record in the USA
It has often been said that “Weather is not climate”, but ultimately it provides the only meaningful way to verify climate models. Did the climate models predict the cold, snowy…
Spencer on his AGU presentation yesterday
Little Feedback on Climate Feedbacks in the City by the Bay by Roy W. Spencer, Ph. D. The Fall meeting of the American Geophysical Union (AGU) here in San Francisco…
Spencer on IPCC admission on climate feedbacks
In Their Own Words: The IPCC on Climate Feedbacks by Roy W. Spencer, Ph. D. Despite the fact that the magnitude of anthropogenic global warming depends mostly upon the strengths…
Scientists Develop New Method to Quantify Climate Modeling Uncertainty
(From PhysOrg.com h/t to Leif Svalgaard )– Climate scientists recognize that climate modeling projections include a significant level of uncertainty. A team of researchers using computing facilities at Oak Ridge…
Fixing the nitrogen cycle in climate modeling
From a press release of Oak Ridge National Laboratory. Key new ingredient in climate model refines global predictions OAK RIDGE, Tenn., Oct. 9, 2009 — For the first time, climate…
Spencer on finding a new climate sensitivity marker
The Search for a Short Term Marker of Long Term Climate Sensitivity By Dr. Roy Spencer. October 4th, 2009 [This is an update on research progress we have made into…
Tornado Threat Increases as Gulf Hurricanes Get Larger
There have been lots of claims about hurricanes since Katrina, many of them linking “global warming” to hurricane frequency, which is of course flat wrong. This study however is in…
German Climate Adviser who says "the West's carbon quotas are used up" once co-authored a paper saying climate models are flawed and that "global warming is also overestimated by the models"
Yesterday on WUWT, a post from Luboš Motl told us how climate science has been proposed as a vehicle for wealth redistribution by Hans Joachim Schellnhuber who is the director…
NASA powers up for the next UN IPCC
From NASA, new fossil fuel powered toys for the boys. Related: “Giant sucking sound” heard in Greenbelt, MD when the switch was thrown. Remember the day you got a brand-new…
Mann hockey-sticks hurricanes: Hurricanes in the Atlantic are more frequent than at any time in the last 1,000 years
Just when you think it couldn’t get any more bizarre in Mann-world, out comes a new paper in Nature hawking hurricane frequency by proxy analysis. I guess Dr. Mann missed…
Evidence that Global Temperature Trends Have Been Overstated
Evidence that Global Temperature Trends Have Been Overstated Dr. Pielke has a new paper, and asked if I’d help “get the word out” I’m happy to oblige – Anthony Guest…
How Sensitive is the Earth’s Climate?
Guest Post By Steve Fitzpatrick Introduction Projections of climate warming from global circulation models (GCM’s) are based on high sensitivity for the Earth’s climate to radiative forcing from well mixed…
A simple analogy on climate modeling – looking for the red spot
This simple visual analogy that Ron House has designed can help readers not familiar with a contentious atmospheric modeling issue get a primer on the it. While not a perfect…
July 24th issue of Science: Study shows clouds may exacerbate global warming with positive feedback, but there's a caveat in the Science summary
This study is being listed as proof by some of the usual alarmist types that the issue of cloud feedback is settled. Before accepting that, read this from the summary…
New paper from Lindzen demonstrates low climate sensitivity with observational data
“…ERBE data appear to demonstrate a climate sensitivity of about 0.5°C which is easily distinguished from sensitivities given by models.” On the determination of climate feedbacks from ERBE data Richard…
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…
