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…

On Chylek et al (2014) – The Atlantic Multidecadal Oscillation as a Dominant Factor of Oceanic Influence on Climate

I was advised of a recent paper that studies the impact of the Atlantic Multidecadal Oscillation on global surface temperatures since 1900. (Thanks, Anthony.) The paper is Chylek et al.…

It Isn’t How Climate Scientists Communicated their Message; It’s the Message

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…

Claim: Analysis indicates that North and tropical Atlantic warming affects Antarctic climate

It seems the ocean cycles get a bigger role than GHG’s in this study. Plus Antarctic models are still FUBAR: The gradual warming of the North and tropical Atlantic Ocean…

Cause of 'the pause' in global warming

Guest essay by Don J. Easterbrook, Dept of Geology, Western Washington University The absence of global warming for the past 17 years has been well documented. It has become known…

Author of its Own Demise – musings on the AMO

Guest essay by Caleb Shaw I once had a very good science teacher who I fear I made wild, not so much by causing small explosions in the back of…

Will their Failure to Properly Simulate Multidecadal Variations In Surface Temperatures Be the Downfall of the IPCC?

OVERVIEW This post illustrates what many people envision after reading scientific papers about the predicted multidecadal persistence of the hiatus period—papers like Li et al. (2013) and Wyatt and Curry…

Chylek et al 2013 shows a linkage between US Southwest climate and AMO/PDO cycles

This paper suggests that the CMIP5 models’ (which IPCC relies upon) predicted US SW temperature sensitivity to the GHG has been significantly overestimated by about a factor of two. Imprint…

Another Peer-Reviewed Paper Predicting the Cessation of Global Warming Will Last At Least Another Decade

A few days ago, the Georgia Tech press release for Wyatt and Curry (2013) included a quote from Marcia Wyatt, who said the stoppage in global warming “could extend into…

Models Fail: Land versus Sea Surface Warming Rates

In Climate Models Fail, using a number of different datasets, I illustrated how the climate models used by the IPCC for their 5th Assessment Report could not simulate climate variables…

On Muller et al (2013) “Decadal variations in the global atmospheric land temperatures”

I received an email yesterday morning advising me that Muller et al (2013) had been published. (Thanks, Marc.) The title of the paper is “Decadal variations in the global atmospheric…

How Long Will the Naturally Caused Drought Persist in the U.S.?

AND DOES THE UPCOMING NCADAC REPORT ADDRESS THE AMO’S INFLUENCE ON THE DROUGHT? Anthony Watts recently published a post about the current drought in the U.S. titled To NCDC: We…

The AMO, Codfish, Seals and Fishermen

Only remotely related to climate change, but perhaps related to politics polluting universities, this essay floats ideas concerning our nations fisheries, and fishes for feedback from WUWT readers. Guest essay…

Multidecadal Variations and Sea Surface Temperature Reconstructions

UPDATE: I’ve added a link at the end of the post for those interested in a copy of it in .pdf format. ########### OVERVIEW This is a somewhat lengthy blog…

Trend To Colder Winters Continues in UK

Guest post by Paul Homewood http://www.metoffice.gov.uk/climate/uk/summaries/anomacts Figures released by the  Met Office show the UK mean temperature for the 2012/13 winter finishing at 3.31C. This is below the long term…

Why El Niño and not the AMO?

Guest Post by Willis Eschenbach On another thread, a poster got me thinking about the common practice of using the El Nino 3.4 Index to remove some of the variability…

Tisdale: How Much of an Impact Does the Atlantic Multidecadal Oscillation Have on Arctic Sea Ice Extent?

Last week I asked Bob Tisdale to take a hard look at potential correlations between the AMO and Arctic sea ice extent, and he rose to the challenge – Anthony…

Pat Michaels – on the death of credibility in the journal Nature

Atmospheric Aerosols and the Death of Nature Guest post by Dr. Patrick Michaels Big news last week was that new findings published in Nature magazine showed that human emissions of…

Mann and coining the AMO and claims of credit

Junkscience.com writes: Did Michael Mann falsely claim to coin a famous climate term actually coined by someone else? In Mann’s new book “The Hockey Stick and Climate Wars”, Mann writes:…
