Over the past few months, there have been a number of articles about how the climate science community could have presented their message differently, or responded differently, so that they…

Notes on the reax to Lewis and Crok, along with another paper looking at climate model output versus data
While the reactions to Lewis and Crok rage, from intellectually lazy trolling at Dr. Judith Curry’s shop by a trio of commenters using the “nyah, nyah, it’s not peer reviewed!” method,…
Claim: large Antarctic polynyas to disappear, yet some are still found in satellite imagery
This PR from McGill University claims that the “deep ocean heat has been unable to get out and melt back the wintertime Antarctic ice”. That might be true, but still, there…
Study: Volcanoes contribute to recent warming ‘hiatus’
Researchers find models must account for volcanic eruptions to accurately predict climate change. From:MIT Joint Program on the Science and Policy of Global Change By the late 1990s, scientists had…
Cowtan and Way (2013) Adjustments Exaggerate Climate Model Failings at the Poles and Do Little to Explain the Hiatus
We’ve already discussed Cowtan and Way’s infilling of HADCRUT4 data in the post On Cowtan and Way (2013) “Coverage bias in the HadCRUT4 temperature series and its impact on recent…
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…
We don't know clouds
Too many variables like clouds to model future climate with precision Guest essay by Rolf Westgard A new United Nations report suggests an imminent danger from global warming. It states…
95% of Climate Models Agree: The Observations Must be Wrong
Note: This is a repost from Dr. Roy Spencer’s blog entry last Friday. I’ve done so because it needs the wide distribution that WUWT can offer. The one graph he…
New study says 'robust modeling' predicted Antarctic sea ice to decrease, but the ice defies modeling
For those of you that have been looking for that point of reference about Antarctica’s increasing sea ice in contrast to the shrinking ice in the Arctic, look no further.…
The IPCC discards its models
Who will believe the CMIP5 models, after the IPCC plenary had to discount their temperature projections? Guest essay by Barry Brill Table SPM.2 Projected change in global mean surface temperature…
Now it's the fungi carbon footprint that isn't in climate models
From a long line of missing things in climate models and the University of Texas at Austin: Symbiotic fungi inhabiting plant roots have major impact on atmospheric carbon, scientists say…
Questions Policymakers Should Be Asking Climate Scientists Who Receive Government Funding
Even before the study of human-induced global warming became fashionable, tax dollars had funded a major portion of that research. Government organizations continue to supply the vast majority of the…
Peer Review; Last Refuge of the (Uninformed) Troll
Current peer review science, by attempting to explain away model failure, in fact confirms that the science is wrong Guest essay by David M. Hoffer It has become a favorite…
Claim: Solar activity not a key cause of climate change, study shows
From the University of Edinburgh , another one-paper syndrome in the making funded by an NGO research council with a political mission to grab a headline. And, another poorly written…
The Magnificent Climate Heat Engine
Guest Post by Willis Eschenbach I’ve been reflecting over the last few days about how the climate system of the earth functions as a giant natural heat engine. A “heat…
Greg Laden Once Again Expresses Something Other Than Fact
In a recent visit to Steve Goddard’s blog, I came across the post Climate Scientists Always Trying To Rewrite Their Own History. It’s about a Tweet by Greg Laden, in…
Dave's Top Ten Reasons Why the Oil Industry Doesn't Spend its Billions on Disproving the Junk Science of AGW
Guest post by David Middleton In my Internet “debates” with warmists, I occasionally encounter challenges like this… We don’t yet not know the real global impact man has on the…
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…
Mechanical Models
Guest Post by Willis Eschenbach [NOTE the update at the end of the post.] I’ve continued my peregrinations following the spoor of the global climate model data cited in my…
Study: lack of cloud physics biased climate models high
The Hockey Schtick brings this to our attention. It seems Dr. Roy Spencer was prescient with his observation: “The most obvious way for warming to be caused naturally is for…
