Twenty-five Climate Models Can't All Be Wrong … Or Can They?
From the NIPCC report: As seemingly never-ending work on developing and improving climate models progresses, there is also a seemingly never-ending set of assessments of how that work is progressing;…
The artist as climate model expert
Guest essay by Charles Battig, M.D. There are reams of publications devoted to the mechanics of computer modeling of global climate dynamics, and the predictive results derived therefrom. Mathematicians, experts…
To President Obama: Let's just assume for a moment we have a climate crisis
As we start hurricane season today, we note the unprecedented 3142 day drought of major hurricane landfalls, shattering a record that goes back to the year 1900. Guest essay by…

Atmospheric Layers, The Biosphere, The Boundary Layer, Microclimate and Inadequate IPCC Models
Guest essay by Dr. Tim Ball During a university presentation I said the climate models do not include the Milankovitch Effect. A person challenged me saying he worked on climate…
Tweaking the climate models: Researchers show emissions from forests influence very first stage of cloud formation
Clouds are the largest source of uncertainty in present climate models. Much of the uncertainty surrounding clouds’ effect on climate stems from the complexity of cloud formation. New research from…
Model Based Extreme Rainfall Claims Not Supported By Actual Data

The Global Climate Model clique feedback loop
Elevated from a WUWT comment by Dr. Robert G. Brown, Duke University Frank K. says: You are spot on with your assessment of ECIMs/GCMs. Unfortunately, those who believe in their…
Major Errors Apparent in Climate Model Evaporation Estimates
Guest essay by Richard J. Petschauer, Senior Member IEEE The physics of evaporation has complications related to what happens at the water / air interface such as wind speed and…
Soil microbe GHG feedback 'less dire than previously thought'
From the International Institute for Applied Systems Analysis The tiniest greenhouse gas emitters Climate feedbacks from decomposition by soil microbes are one of the biggest uncertainties facing climate modelers. A…
Claim: Climate Models Underestimate Costs to Future Generations
One wonders how they can make claims like that when we see models vs reality like this: Future generations will have to pay more for today’s carbon emissions than what…
IPCC WGII report relies on exaggerated climate model results
WGII climate risks overstated and invalid Guest essay by Larry Hamlin The UN IPCC AR5 WGII final climate report has been released. This UN WGII report attempts to evaluate various…
Why models can't predict climate accurately
By Christopher Monckton of Brenchley Dr Gavin Cawley, a computer modeler the University of East Anglia, who posts as “dikranmarsupial”, is uncomfortable with my regular feature articles here at WUWT…
With ENSO, chaos rules, models drool
A new paper in Nature from the Department of Oceanography, School of Ocean and Earth Science and Technology, University of Hawaii, makes a somewhat surprising claim about predicting ENSO events.…
Oh Noes! Salamanders shrinking due to climate change
A video of this press release follows. Here’s a screen cap from it. CLEMSON, S.C. — Wild salamanders living in some of North America’s best salamander habitat are getting smaller…
New Statistical Models Could Lead to Better Predictions of Ocean Patterns and the Impacts on Weather, Climate and Ecosystems
From the University of Missouri, note the operative word “could”. COLUMBIA, Mo. – The world’s oceans cover more than 72 percent of the earth’s surface, impact a major part of…
IPCC Scientists Knew Data and Science Inadequacies Contradicted Certainties Presented to Media, Public and Politicians, But Remained Silent
Guest essay by Dr. Tim Ball I have no data yet. It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit…
The Future of Models
Guest essay by Nancy Green At the close of the 19th century physics was settled science. The major questions had been answered and what remained was considered window dressing. Our…
