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,…
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…
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…
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.”
Climate Oscillations 12: The Causes & Significance
The connection between orbital mechanics, solar variability and climate is complex. I don’t know the answer, but this post will bring you up to date.
Climate Oscillations 11: Oceanic Niño Index (ONI)
ENSO affects weather all over the world but doesn’t track the global mean surface temperature (GMST), at least for the last 35 years. Is GMST an appropriate measure of climate…
Climate Oscillations 10: Aleutian Low – Beaufort Sea Anticyclone (ALBSA)
The Aleutian Low – Beaufort Sea Anticyclone climate index or ALBSA is designed to predict snow and ice melting times on the North Slope of Alaska.
Climate Oscillations 9: Arctic & North Atlantic Oscillations
The AO and NAO are the dominant modes of climate variability in the Northern Hemisphere and neither of them can be reproduced using climate model output.
Climate Oscillations 8: The NPI and PDO
The NPI and PDO are closely related and do not correlate well with global warming.
Climate Oscillations 7: The Pacific Mean SST
This is a comparison of Pacific SST to HadCRUT5, how we4ll do they compare?
Climate Oscillations 6: Atlantic Meridional Mode (AMM)
By Andy May The Atlantic Meridional Mode Index (AMM) describes meridional variability in the tropical Atlantic. The area of interest is the ocean area inside 32°N to 21°S and from…
Climate Oscillations 5: SAM
The Southern Annular Mode (SAM) has a major influence on global climate.
