Does the Uptick in Global Surface Temperatures in 2014 Help the Growing Difference between Climate Models and Reality?
Guest Post by Bob Tisdale This post includes calendar year 2014 global surface temperature data from GISS and NCDC. I thought it would be interesting to begin the introduction as…
Peer-reviewed pocket-calculator climate model exposes serious errors in complex computer models and reveals that Man’s influence on the climate is negligible
What went wrong? A major peer-reviewed climate physics paper in the first issue (January 2015: vol. 60 no. 1) of the prestigious Science Bulletin (formerly Chinese Science Bulletin), the journal…
#AGU14 poster demonstrates the divergence problem with IPCC climate models and observations
Earlier this week I to reported on some of the poster sessions at the American Geophysical Meeting but was told the next day that I’m not allowed to photograph such…
November 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update
Guest Post by Bob Tisdale This post provides an update of the data for the three primary suppliers of global land+ocean surface temperature data—GISS through November 2014 and HADCRUT4 and…
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…
October 2014 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update
Guest Post by Bob Tisdale I’ve added a graph of the difference between the observed global temperature anomalies (GISS LOTI) and the climate model simulations of that metric by the…
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…
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…
'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…
Lewandowsky and Oreskes Are Co-Authors of a Paper about ENSO, Climate Models and Sea Surface Temperature Trends (Go Figure!)
UPDATE 2: Animation 1 from this post is happily displaying the differences between the “Best” models and observations in the first comment at a well-known alarmist blog. Please see update…
Another missing piece of the climate model puzzle – dust
From Scripps: Global climate models fail to simulate key dust characteristics African dust plays a key role in cloud formation, hurricanes and other global climate phenomena but models can’t characterize…
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;…
Termites, fungi, models, and climate change
From the University of Central Florida Climate change models could have a thing or two to learn from termites and fungi, according to a new study released this week. For…
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…
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…
Maybe the IPCC’s Modelers Should Try to Simulate Earth’s Oceans
UPDATE (April 6, 2014): I’ve added a link to a follow-up post about the cause of the observed C-shaped warming pattern in the Pacific. # # # The climate models…
Computer model predicts vastly different ecosystem in Antarctica's Ross Sea in the coming century
NSF Press Release 14-028 Rising temperatures and changing wind patterns sure to affect predator-prey relationships, researchers say Adelie penguins cross ice floes near a lead–or opening–in the sea ice at…
The Lewis and Crok exposition – Climate less sensitive to Carbon Dioxide than most models suggest
Full papers plus additional comments from co-author Nic Lewis follow. I have added some relevant diagrams and tables from the report, plus reproduced the foreword by Dr. Judith Curry as…
Still chasing consensus – on building a climate consensus model
Statistics research could build consensus around climate predictions Philadelphia, PA—Vast amounts of data related to climate change are being compiled by research groups all over the world. Data from these…
Another dubious linkage to 'climate change': Modeled increase in Arctic Cyclones
I don’t put much merit in this study especially when we see statements like “statistically significant, though minor, increase in extreme Arctic cyclone frequency” because we really haven’t had good…
New hockey team paper: models tuned to tree rings and other palaeo-climate reconstructions
A new paper is out in a special issue of Climate of the Past called Progress in paleoclimate modelling It is from the ‘hockey team’ and titled “Using palaeo-climate comparisons…
The Overselling of Climate Modeling Predictability on Multi-Decadal time Scales in the 2013 IPCC WG1 Report – Annex 1 Is Not Scientifically Robust
Guest essay by Roger A. Pielke Sr. Introduction I have posted in the past how the development of multi-decadal regional climate projections (predictions) to give to policymakers and the impact…
