This blog has “667-per-cm.net” in it WordPress URL, and is titled 667 per cm, that corresponding to the frequency of a big spectral line for carbon dioxide (see below) which happens to line close to the peak blackbody emissions region for Earth at nominal temperatures. These physical facts and the proximity of that line to Earth’s blackbody emissions mode is a key element in the reason why climate change due to excess atmospheric carbon dioxide occurs.
Eli Rabett of Rabett Run has a good deal more information about the fine structure of the CO2 band at .
Eli Rabett has posted a fine series of deep tutorials about the spectroscopic basis for CO2‘s absorption. This is in connection with an answer to questions posed by Judge Alsup regarding the physical science basis of climate change. Here are links to Eli’s posts:
- Dear Judge Alsup: The Spectroscopic Basis
- Dear Judge Alsup: The Quantum Interlude
- Dear Judge Alsup: Putting on the Pressure
Eli has once again posted an excellent tutorial. This is an illustration of how “the presence of a colder body can limit the rate at which a warmer one emits energy”, and it exists to parry silly — and probably disingenuous — climate denier remarks about how global warming somehow violates basic physics, most frequently citing the Second Law of Thermodynamics, and various misstatements of it which confuse the inexperienced.
And, in a second installment, Eli addresses energy balance throughout the atmosphere and implications for warming and radiative forcing, including the effects of convection.
The header sometimes bears the quote
… [I]t is noteworthy that the principle of unbiasedness in estimation is currently held in low esteem by the consensus of statisticians.
This is from L. J. Savage’s “The theory of statistical decision“, Journal of the American Statistical Association, 1951, 46(253), 55-67. What’s notable is that it implies that research in Statistics was anticipating the earthshaking discovery and publication of Stein’s example in 1955. It is subtle, but that result has, along with the availability of prodigious computational resources, transformed statistical science since its full-fledged appearance in the 1960s with James-Stein estimators. There are now many explanations:

- S. S. Qian, C. A. Stow, Y. K. Cha, “Implications of Stein’s Paradox for environmental standard compliance assessment“, Environmental Science and Technology, 2015.

The American Institute of Physics has a nice page describing simple models of climate change. It also features a prescient quote from Guy Stewart Callander:
This is a difficult subject: by long tradition the happy hunting ground for robust speculation, it suffers much because so few can separate fact from fancy.
This is from:

Jan Galkowski is a retired data scientist, statistician, and quantitative engineer.
Jan is a member of the Azimuth Project.
He has an S.M. degree in EE & Computer Science from the Massachusetts Institute of Technology (“MIT”), and a B.S. degree in Physics from Providence College. He has taken additional graduate level courses in mathematics, signal processing, geology, geophysics, statistics, computer science, and history of science from Cornell University, Binghamton University, Syracuse University, University of Illinois–Urbana-Champaign, MIT, Colorado State University, West Point Military Academy, Naval Postgraduate School–Monterey, AFCEA, and Harvard University. Some of these were sponsored by DARPA.
Mr Galkowski served as a statistician and data scientist for Akamai Technologies, a position he held for 13 years, a data warehouse developer, test engineer, advisory software engineer, and entrepreneur for Cornell University, Sensis, Westinghouse Nuclear Automation, Loral Federal Systems, IBM Federal Systems, and Aetna U.S. Healthcare. He has a deep interest in science, especially oceanography, ecology, quantitative biology, and dynamical systems models pertaining to these, and especially those related to climate science.
Mr Galkowski’s portfolio of highlighted work is available here.
Mr Galkowski is a member of no social media platforms. However, he is also a diligent reader of The Financial Times, and of The New York Times, an his comments can often be found there. Other favorites are The London Review of Books, The Economist, and Goodreads.
Mr Galkowski’s areas of interest are:
- Quantitative ecology and phenology of bryophytes and lichens, and field work supporting these, especially macrophotography and microphotography. Particular interest in use of mosses as phenological indicators .
- Population ecology, quantitative biology, and methods from genomics.
- Tree-based Bayesian methods like Bayesian Regression and Classification Trees.
- Keen interest in self-documenting calculations, backed by and R.
Jan is a member of:

… Politically Speaking …
While I continue to be a climate hawk and a Hermann Scheer solar revolutionary, our collective failure to make progress on climate change mitigation and the ineffectiveness of progressive environmentalists has, upon reflection, converted me to ecomodernism and ecopragmatism, fully accepting the Ecomodernist Manifesto.
Solar photovoltaic technology is a revolutionary energy source for the reasons Professor Tony Seba details, and because it is a democratically empowering development, returning control of energy to the people and public at large, denying central concentrators of such power the influence they presently enjoy. Thus, it heralds the oncoming of a green century and the return of electrical power to the people.
In 2020, Mr Galkowski is studying the proposals of Professor Mark Z Jacobson’s team for 100% wind, water, storage, and solar energy for 140 countries, including the United States, and planning to co-author an adult education course based upon Professor Jacobson’s forthcoming book on the plan. (See also, and a presentation, and a lecture.) This is, in my opinion, our best hope forward. It does something. It doesn’t sit around, agonizing.
