“To turn the noun ‘resources’ into the verb ‘resourcing,’ to discard entirely the notion of a resource ‘glass’ that is somewhere between full and empty, requires one more analytic step—a step that Zimmermann failed to take.”
In 1972, just two years after the first Earth Day, a team of scholars from MIT published a 200-page book called The Limits to Growth. Using the emerging instrument of computer models, they created a worldwide stir by suggesting that science had now put numbers to a few self-evident truths. Non-renewable resources are fixed; the consumption of such resources must eventually end; any civilization based on such consumption must collapse. New York Times columnist Anthony Lewis called the work “likely to be one of the most important documents of our age” (January 28, 1972).
Of course, the scholars acknowledged that they were dealing with variables.…

The example concerns the Texas winter of 2020–2021 and Storm Uri that blacked out most of Texas.
“NOAA’s timely and accurate seasonal outlooks and short-term forecasts are the result of improved satellite observations, more detailed computer forecast modeling, and expanding supercomputing capacity,” said Neil Jacobs, Ph.D., acting NOAA administrator. (below)
“Cold extremes decrease and warm extremes increase in a warmer world, and cold extremes tend to be more sensitive to global warming than the warm ones.” (emphasis added) Science Bulletin, below
Humility in the face of unknowns is a worthy attribute.…

Until he can return to work, he has asked me to post “classic” MR entries. A blog post explaining Vaclav Smil’s concept of “power density” surely qualifies. This is the key concept for understanding a civilization’s energy needs.
Unfortunately, our MR files contain no concise explanation of the concept in layman’s language. (We have many explanations that no conceivable lay reader—myself most definitely included—could possibly understand or appreciate.) The closest thing I could find to a useful journalistic entry was a blog post by Kent Hawkins—a retired electrical engineer in Ontario—published on February 20, 2013. It is reprinted below.—Roger Donway, Managing Editor.
Power Density Separates the Wheat from the Chaff
By Kent Hawkins — February 20, 2013
“Power density (W/m2) is perhaps the most revealing variable in energetics…”[1]- Vaclav Smil
It may be a bit of an exaggeration to say that understanding power density may be all the average person requires to put our energy sources and needs into perspective, but there is some merit in this argument.…
