Factual errors in Cheng et al. (2019) ocean warming paper

“There are a number of statements in Cheng et al. (2019) ‘How fast are the oceans warming’, (‘the paper’) that appear to be mistaken and/or potentially misleading. My analysis of these issues is followed by a reply from the paper’s authors: Lijing Cheng, John Abraham, Zeke Hausfather and Kevin Trenberth.” click here

Ocean warming in climate models differ widely

“One of the problems with the results in the Cheng et al. study is how the 90% confidence intervals are computed. Most people will simply assume they are related to how well the stated numbers are known. That is, how good the various observational and model estimates of ocean warming are.

But they would be wrong.” click here

Climate multi-model means and anomalies do not reflect physical realities

“A multi-model mean of 81 ensemble members, where the models are all giving wrong answers, some worse than others, simply provides us with a consensus of the wrong answers. And to compound that, the RCP8.5 scenario is, more and more often as days go by, being found to be unrealistic.” click here

HadCRUT4 data limitations render IPCC analyses unreliable

“HadCRUT4 is the primary dataset used by the Intergovernmental Panel on Climate Change (IPCC) to make its dramatic claims about “man-made global warming”, to justify its demands for trillions of dollars to be spent on “combating climate change” and as the basis for the Paris Climate Accord.

But according to a groundbreaking analysis by Australian researcher John McLean it’s far too sloppy to be taken seriously even by climate scientists, let alone a body as influential as the IPCC or by the governments of the world.” click here

Climategate – the next episode from Arizona

“Nearly seven years ago, on December 7th, 2011, the Free Market Environmental Law Clinic’s (FME Law) sought public records from the University of Arizona related to the Mann-Bradley-Hughes temperature reconstruction that looks like a hockey stick, and development of an Intergovernmental Panel on Climate Change (IPCC) report.  They refused much of the request and FME Law sued.  Now (on September 18th, 2018) legal counsel for the University informed FME Law that they were done, that they would be withdrawing their appeal of the trial court’s decision, end the case and disclose the records.” click here

Ocean cycles synchronous with global temperature fluctuations

“Now isn’t it a bit odd that the authors made absolutely no mention of the ocean cycles in the abstract? As our regular readers know, the ocean cycles run surprisingly synchronous with the fluctuations in global temperatures, i.e. the key factors here are the AMO and PDO.” click here

A spirited discussion over global temperature rise and IPCC models.

“No matter how hard climate-catastrophe obsessed alarmists attempt to beat out a little doom from the data, their results still fall far way short of their projections. Moreover, the modest warming the planet has seen over the recent decades is tied more to natural cycles.” click here
