Internal Multidecadal and Interdecadal Climate Oscillations: Absence of Evidence Is No Evidence of Absence

Altogether, I conclude that the paper M20 is not advancing our understanding of the nature of multi- and interdecadal oscillations such as the AMO and PDO.

Study: Atlantic Ocean circulation is not collapsing – but the press release adds climate porn

New data shows 10 year decline in the Atlantic Conveyor

Laurence Hecht writes: This review in the 19 Jun 2015 issue of Science  reported solid observational evidence (not proxies and modeling à la Rahmstorf and Mann) of a 10-year trend of decline…

James Hansen's latest doomsday paper falls flat on its face, grounds his 'flying boulders'

James Hansen, formerly head of NASA GISS published a new study Tuesday March 22nd in the journal Atmospheric Chemistry and Physics, claiming global warming, sea level rise, and severe storms, could be…

Study: There is no real evidence for a diminishing trend of the Atlantic Meridional Overturning Circulation

This paper was just published today in the Journal of Ocean Engineering and Science. It seems to be definitive refutation of Mann and Rahmstorf’s claims, and quells the alarm bells that…

Yet another prediction of doom over Greenland ice melt and the AMOC that we can ignore

From the “fresh melt water will disrupt the planet” department, except that this ongoing alarm has already been debunked by NASA, see: NASA refutes Mann and Rahmstorf – Finds Atlantic ‘Conveyor…

New Paper Confirms the Drivers of and Processes behind the Atlantic Multidecadal Oscillation

Oh noes! Fishy modeling study says 'Fish and Chips' to disappear in the UK

I get this daily newsletter from a paid political pot stirrer called “Climate Nexus”, which is actually a Madison Avenue PR firm. They write today of a new paper, Rutterford…

NASA refutes Mann and Rahmstorf – Finds Atlantic 'Conveyor Belt' Not Slowing

From the “we told you so yesterday” and the “settled science” department. This study was released in 2010, and they used actual measurements, rather than proxy data and reconstructions like…

Michael Mann and Stefan Rahmstorf claim the Gulf Stream is slowing due to Greenland ice melt, except reality says otherwise

UPDATED – see below From your “Day after Tomorrow” department (where a slowing Gulf Stream turned NYC into an icebox) comes this claim from the bowels of Mannian Science. Unfortunately,…

Will the Next El Niño Bring an End to the Slowdown in Global Surface Warming?

Rebuttal to Chen and Tung (2014) highlighted in “Cause for ‘The Pause’ #38 – Cause of global warming hiatus found deep in the Atlantic Ocean” Numerous scientific papers have reported…

And this excuse makes 30. Dueling press releases on 'the pause', blaming Pacific Trade Winds on 'Atlantic warming'

Previously, we had 29 excuses for “the pause” now we have 30. When a paper is published by multiple authors, the universities of those authors often produce separate press releases…

New paper: The Atlantic Multidecadal Oscillation as a dominant factor of oceanic influence on climate

Just two explanatory variables (GHG and AMO) still account for 93% of the temperature variance. Dr. Leif Svalgaard sends word of this article in Geophysical Research letters by Petr Chylek,…

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…
