Guest “nothing to add” by David Middleton Michael Schellenberger’s Environmental Progress page has published a very cool slide deck, related to his new book Apocalypse Never. Here are the first five slides: Mr. Schellenberger rocks! Like Bjorn Lomborg, Ted Nordhaus and Scott Tinker, he opens a pathway for constructive dialogue on environmental issues.

The Homeric seems to have started about 2400 years before the Spörer (or Maunder?) Minimum, which may be its more recent equivalent. Researchers have found evidence of a ‘2400-year cycle in atmospheric radiocarbon concentration’ – for example, see here.
Much of the article below appears to have come from Wikipedia, but there it also says:
“Variations in the solar output have effects on climate, less through the usually quite small effects on insolation and more through the relatively large changes of UV radiation and potentially also indirectly through modulation of cosmic ray radiation. The 11-year solar cycle measurably alters the behaviour of weather and atmosphere, but decadal and centennial climate cycles are also attributed to solar variation.”

The Homeric Minimum is a grand solar minimum that took place between 2,800 and 2,550 years before present, says the Grand Solar Minimum website.
It appears to coincide with, and have been the cause of, a phase of climate change at that time, which involved a wetter western and drier eastern Europe.
This had far-reaching effects on human civilization, some of which may be recorded in Greek mythology and the Old Testament.
The Homeric Minimum is a persistent and deep solar minimum that took place between 2,800 and 2,550 years before present, starting around 830 BC and resembling the Spörer Minimum.
This minimum is sometimes considered to be part of a longer “Hallstattzeit” solar minimum between 705–200 BC, that also includes a second minimum between 460 and 260 BC. The Homeric Minimum however also coincided with a geomagnetic excursion named “Etrussia-Sterno”, which may have altered the climate response to the Homeric Minimum.
The Homeric Minimum has been linked with a phase of climate change, during which the Western United States, Europe and the North Atlantic became colder and wetter although the eastern parts of Europe appear to have become drier. This climate oscillation has been called the “Homeric Climate Oscillation”.
Human cultures at that time underwent changes, which also coincide with the transition from the Bronze Age to the Iron Age. The climate fallout of this prolonged solar minimum may have had substantial impact on human societies at that time.
A variety of phenomena have been linked to the Homeric Minimum:

Petroleum-based products cannot be ‘electrified’.
By Ronald Stein ~
The rage these days from the Green New Deal, the Paris Accord, and the recent Democrats Clean Energy Climate Policy are all focused on renewable energy to replace our demands from fossil fuels. But wait – renewable energy from wind and solar is only renewable ELECTRICITY! At best, that renewable electricity is intermittent as it depends on wind and sunshine to produce any electricity.
Before 1900 the world had no medications, electronics, cosmetics, plastics, fertilizers, and transportation infrastructures. Looking back just a few short centuries, we’ve come a long way since the pioneer days.
Also, before 1900, the world had very little commerce and without transportation there is no commerce. The two prime movers that have done more for the cause of globalization than any other: the diesel engine and the jet turbine, both get their fuels from oil. Road and air travel now dominate most…

The wind power cult have no difficulty in justifying the destruction of pristine landscapes; the dismemberment of once cohesive, rural communities; the creation of toxic waste lands in China (where the rare earths essential to wind turbines are processed); power prices that punish the poorest and most vulnerable in society; and barely bat an eyelid at the slaughter of millions upon millions of birds and bats, across the globe.
In the US, a recent study has exposed the fact that the number of bats belted into oblivion by these things is magnitudes greater than originally estimated by wind industry controlled surveys.
Instead of a mere 2 to 3 million critters being annihilated annually, it appears that the numbers of bats killed by wind turbines in the USA may well be somewhere north of 20 million, every single year.
‘Green’ Carnage Study: In 2019 US Wind Turbines Killed 3.7 Million Bats – And This Is A Gross Underestimate

Due to the expansion of wind energy projects in the United States in the last decade, a conservative estimate for yearly bat fatalities from wind turbines ranges between 1.7 to 3.7 million. A new study suggests death numbers may be 4 to 7 times higher due to carcass search deficiencies.
It is estimated that North American migratory bat populations will decline by 90% over the next 50 years due to the expanding presence of wind turbines (Frick et al., 2017). As of 2015, about 25% of North American bat species were already considered vulnerable or endangered (Hammerson et al., 2017).

A harrowing new study suggests researchers may be vastly underestimating wind turbine bat fatalities due to biased-low carcass detection practices.
Smallwood and Bell (2020) report that dogs perform far better than humans at locating bat carcasses, but even dogs miss 3 out of every 4 bats observed colliding with wind turbines. This is because a) injured bats may temporarily recover enough to fly 10s of meters away from the collision site, and b) because scavengers can quickly collect the freshly dead or injured bats before dogs (and humans) can recover them.
Consequently, the 1.7 to 3.7 million bats killed by U.S. wind turbines each year (2019) may be a vast underestimate. Smallwood and Bell suggest the real death numbers are likely 4 to 7 times higher than that.
At this rate, the extinction clock for North American bats may not be 50 years off, but only a decade or two away.
