Hump Day Hilarity – model the bouncing ball
Josh writes: Talking of Climate Models, there is another great Climate Audit post titled “Unprecedented” Model Discrepancy where Richard Betts, once again, provides cartoon inspiration in the comments. It’s a bit…
Mixed Signals from the NOAA ENSO Blog about Climate Models
Guest Post by Bob Tisdale There’s a new post at the NOAA ENSO blog titled Climate Change and ENSO: Take 2. It’s a guest post by Matt Collins of the…
Model claim: airplanes of the future won't be able to take off at some airports due to global warming
Density altitude is the biggest factor in aircraft take off on a given runway length, temperature, and altitude. I know this from firsthand experience as I used to be a…
Who needs an Orbiting Carbon Observatory to track it when you can model Carbon Dioxide movement?
Video follows. I had at first thought that this press release from NASA Goddard was telling me that they had taken the data from their new Orbiting Carbon Observatory and…
Claim: "golden age of climate science, models" is upon us
Latest Supercomputers Enable High-Resolution Climate Models, Truer Simulation of Extreme Weather Berkeley Lab researcher says climate science is entering a new golden age. Not long ago, it would have taken…
Seven Years Ago, An IPCC Lead Author Exposed Critical Weaknesses of the IPCC Foretelling Tools
Guest Post by Bob Tisdale NCAR’s Dr. Kevin Trenberth was a lead author of the IPCC’s 2nd, 3rd and 4th Assessment Reports. Near to the publication of the IPCC’s 4th…
On the Elusive Absolute Global Mean Surface Temperature – A Model-Data Comparison
Guest Post by Bob Tisdale With the publication of the IPCC 5th Synthesis Report, I thought there might be some interest in a presentation of how well (actually poorly) climate…
A Simple Truth; Computer Climate Models Cannot Work
Guest opinion by Dr. Tim Ball – Ockham’s Razor says, “Entities are not to be multiplied beyond necessity.” Usually applied in making a decision between two competing possibilities, it suggests…
'Icebergs once drifted to Florida'
From the University of Massachusetts at Amherst and the department of melted evidence, comes this interesting story about the last ice age. Icebergs once drifted to Florida, new climate model…
Test Driving the Solar Notch-Delay Model
DISCLAIMER: There are still many unanswered questions about this model. I provide this essay for the purposes of discussion, but I give no pro or con endorsement – Anthony Guest…
Study: Southwest may face ‘megadrought’ this century
From Cornell University by Melissa Osgood | Due to global warming, scientists say, the chances of the southwestern United States experiencing a decade long drought is at least 50 percent,…
A Lead Author of IPCC AR5 Downplays Importance of Climate Models
Richard Betts heads the Climate Impacts area of the UK Met Office. The first bullet point on his webpage under areas of expertise describes his work as a climate modeler.…
Pointless Ohio State study predicts the obvious with models – fish will die as streams dry out
Even more troubling, why does a waste of time study like this get funded by the Department of Defense Strategic Environmental Research and Development Program? I don’t want defense money…
Claim: Human contribution to glacier mass loss on the increase
From the University of Innsbruck, another modeling study. This news release is available in German. The ongoing global glacier retreat causes rising sea-levels, changing seasonal water availability and increasing geo-hazards.…
SNAP: 'Data says global cooling, physical model says it has to be warming'
A global temperature conundrum: Cooling or warming climate? From the University of Wisconsin-Madison MADISON, Wis. — When the Intergovernmental Panel on Climate Change recently requested a figure for its annual…
CO2, destroyer of entire continents at the touch of a knob
From the University of New Hampshire and the department of “CO2 controls everything with a single big red knob” (as stated in the article) comes this modeling inanity. Never mind…
'Prediction is very difficult, especially about the future.'
That headline is attributed to physicist Niels Bohr, but a later more popular version is attributed to Yogi Berra. But. like predicting the future, it seems that the true provenence…
'Climate models not only significantly over-predict observed warming in the tropical troposphere, but they represent it in a fundamentally different way than is observed'
New Paper by McKitrick and Vogelsang comparing models and observations in the tropical troposphere This is a guest post by Ross McKitrick (at Climate Audit). Tim Vogelsang and I have a…
New Climate Model Introduced, now with knobs!
Due to the cutbacks in funding for climate science, a new climate model has been introduced to help politicians justify unnecessary laws that regulate carbon dioxide emissions…
