First-time direct proof of chemical reactions in particulates
Paul Scherrer Institute Researchers at the Paul Scherrer Institute PSI have developed a new method to analyse particulate matter more precisely than ever before. With its help, they disproved an…
A Tale Of Two Convergences
Guest Post by Willis Eschenbach In the course of doing the research for my previous post on thunderstorm evaporation, I came across something I’d read about but never had seen.…
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…
Global Warming is REAL but NOT a Big DEAL
Guest essay by Dr. Ira Glickstein We’ve reached a turning point where it is hard for any Global Warming Alarmist to claim (with a straight face) that the world as…
Climate Craziness of the Week: only the 'cooler' models are wrong – the rest say 4ºC of warming by 2100
From the University of New South Wales and Dr. Steven Sherwood: “Climate sceptics like to criticise climate models for getting things wrong, and we are the first to admit they…
On the Futility of Long-Range Numerical Climate Prediction
Note: two events at AGU13 this morning dovetail in with this essay. The first, a slide from Dr. Judith Lean which says: “There are no operational forecasts of global climate…
From 90% to 95% confidence level: How IPCC claims can be at the same time consistent and absurd.
We have been expecting too much from the IPCC about its confidence level increase: the explanation may actually be simple… and surprising. Guest essay by Stephane Rogeau Image: From IPCC…
Climate models – worse than we thought
Observations Now Inconsistent with Climate Model Predictions for 25 (going on 35) Years By Paul C. “Chip” Knappenberger and Patrick J. Michaels Question: How long will the fantasy that climate…
A Sea Change for Climate Science?
By David Stockwell writing in Quadrant Online As CO2 climate models falter and even the IPCC backs off its estimates, it just may be that a radical shift in thinking…
Quite possibly the world's dumbest Kickstarter project for climate
God help us. These “artistes” write: The scientific community can meet us in December when we bring the calendar to the American Geophysical Union Fall Meeting. This is the world’s…
Epic Failure of the Canadian Climate Model
Guest Essay by: Ken Gregory The Canadian Centre for Climate Modeling and Analysis located at the University of Victoria in British Columbia submitted five runs of its climate model CanESM2…
90 climate model projectons versus reality
Reality wins, it seems. Dr Roy Spencer writes: As seen in the following graphic, over the period of the satellite record (1979-2012), both the surface and satellite observations produce linear…
New Book by Bob Tisdale: “Climate Models Fail”
THANK YOU Many thanks to everyone who has purchased a copy of Climate Models Fail — and to those who are considering it. And thank you, Anthony, for posting this…
Gatekeeping at Geophysical Research Letters
Dr. Judith Curry writes: As the IPCC struggles with its inconvenient truth – the pause and the growing discrepancy between models and observations – the obvious question is: why is…
Hump Day Hilarity – looks like a tipping point to me
This bit of humor is courtesy of Dr. Roy Spencer, who made it a lead in for his recent blog post: A climate modeler increasing his model’s sensitivity.
Lomborg: climate models are running way too hot
Guest essay by Bjørn Lomborg The current climate models are running way too hot. Over the past 30 years, they are at least predicting 71% too much heat. Maybe 159%.…
National Academy of Sciences: climate models still 'decades away' from being useful
From the National Academy of Sciences report A National Strategy for Advancing Climate Modeling: Computer models that simulate the climate are an integral part of providing climate information, in particular…
Statistical proof of 'the pause' – Overestimated global warming over the past 20 years
Commentary from Nature Climate Change, by John C. Fyfe, Nathan P. Gillett, & Francis W. Zwiers Recent observed global warming is significantly less than that simulated by climate models. This…
Another uncertainty for climate models – different results on different computers using the same code
New peer reviewed paper finds the same global forecast model produces different results when run on different computers Did you ever wonder how spaghetti like this is produced and why…
Quote of the week – Nature on the failure of climate models
From the world of Claimatology™, comes this smackdown from Nature.
Models Fail: Scandinavian Land Surface Air Temperature Anomalies
UPDATE: I’ve added a comment by Marcel Crok to the end of the post. #### The climate models being used by the IPCC for their upcoming 5th Assessment Report show…
