| In Defense of Carbon Dioxide |
The demonized chemical compound is a boon to plant life and has little correlation with global temperature.
By Harrison H. Schmitt And William Happer
Of all of the world's chemical compounds, none has a worse reputation than carbon dioxide. Thanks to the single-minded demonization of this natural and essential atmospheric gas by advocates of government control of energy production, the conventional wisdom about carbon dioxide is that it is a dangerous pollutant. That's simply not the case…
REALLY?
Like The Wisdom Of The Ancients, the conventional wisdom is very often true :

Deadly CO2 gases in the Plutonium of Hierapolis
(Denizli, Turkey)
They reach concentrations during the night that would easily kill even a human being within a minute. These emissions are thought to reflect the Hadean breath and/or the breath of the hellhound Kerberos guarding the entrance to hell.
The origin of the geogenic CO2 is… the Babadag fracture zone. Our measurements confirm the presence of geogenic CO2 in concentrations that explain ancient stories of killed bulls, rams, and songbirds during religious ceremonies.
They also strongly corroborate that at least in the case of Hierapolis, ancient writers like Strabo or Plinius described a mystic phenomenon very exactly without much exaggeration.

This Roman 'gate to hell' killed its victims with a cloud of deadly carbon dioxide
Rediscovered just 7 years ago, the gate to hell at the ancient city of Hierapolis, in modern-day Turkey, is a stone doorway leading to a small cave-like grotto. The gate was built into one wall of a rectangular, open-aired arena, topped by a temple and surrounded by raised stone seating for visitors. The city itself sits in one of the region’s most geologically active areas; 2200 years ago, its thermal springs were believed to have great healing powers. But a deep fissure running beneath Hierapolis constantly emits volcanic carbon dioxide, which pours forth as a visible mist. The gate—also known as the Plutonium, for Pluto, the god of the underworld—is built directly above it. In 2011, archaeologists showed that the gate is still deadly: Birds that fly too close suffocate and die.
Now, a research team led by volcano biologist Hardy Pfanz at the University of Duisburg-Essen in Germany has studied the shrine’s killing potential in greater detail. Pfanz and his colleagues measured the CO2 concentration in the arena over time.
During the day, the sun’s warmth dissipates the gas. But at night the gas—slightly heavier than air—billows out and forms a CO2 “lake” on the sheltered arena floor. It is particularly deadly at dawn, when the CO2 concentration 40 centimeters above the arena floor reaches 35%, enough to asphyxiate and kill animals or even people within a few minutes, Pfanz says.
