Earth Energy Imbalance: The Sun versus CO2

Do solar and greenhouse gas radiation affect ocean heat content in the same way?

ECS, EffCS, and the 25-year Paradox, What CERES tells us

Computing ECS with CERES data

TOA EEI versus Surface Net Flux

The Earth Energy Imbalance (EEI) is calibrated or “tuned” to match changes in ocean heat content. TOA radiation measurements need tuning. Given the AMO oscillation is 60-70 years long, is…

Stefani on the Sun vs. CO2 as climate drivers

The solar aa index predicts global sea surface temperatures to 2000 better than CO2, and as well as CO2 combined with the aa index. After 2000 CO2 is needed in…

Is the Ocean Surface a boundary condition?

The ocean skin layer is not a boundary condition or infinitesimally small surface and should not be treated as such.

Efficacy of downwelling IR

Is 90% of increasing ocean heat content due to man-made greenhouse gases as claimed by the consensus and the IPCC?

The Neoglacial Period

Solar variability did contribute to climate change over the past 1,000 years.

Holocene Glacier Records

Recent glacial records do not support the idea of anthropogenic global warming.

Holocene Warming

It is highly unlikely that today is the warmest Earth has been in the past 6,800-7,800 years or that today’s warming is unprecedented.

Re-evaluating the Concern of Climate Change

By Andy May I’ve just been made aware of a paper critical of the “consensus” view that man-made climate change is dangerous. It is by Ashutosh Sharma, Vinit Vithalrai Shenvi,…

The Cost of Wind and Solar Power Backup

Are wind and solar cheaper than natural gas? Maybe not.

Weather Reanalysis Models

By Andy May My new paper (May, 2025) emphasizes that while many of the underlying observations used to build weather reanalysis datasets, such as ERA5 (European Centre for Medium-Range Weather…

The Monthly ITCZ Central Latitude

The ITCZ moves with the Sun and is hard to define.

R Programming tips to read and plot IGRA2 Radiosonde data

By Andy May R is an extremely powerful programming language for processing, analyzing and displaying data from large datasets. As discussed in the first post of this series on analyzing…

R has improved dramatically.

The Story behind my Paper on the ITCZ and the Hadley Circulation

By Andy May It all began eight years ago when I read and reviewed Ronan and Michael Connolly’s first three papers on their ideas about the “molar density intersection” which…

What is a “climate crisis?”

By Andy May In a new paper by Gianluca Alimonti and Luigi Mariani, they argue that the public needs a proper definition of precisely what a climate crisis is to…

‘Orwellian’ firing at the American Journal of Economics and Sociology for publishing a climate skeptic paper

Journal editor fired for publishing the peer reviewed paper of a “climate denier.”
