“… the UK Health and Safety Executive has defined safe CO2 limits for the workplace. The limit for long-term exposure is 0.5% (5,000 ppm) but for shorter encounters it is 2% [20,000 ppm]. Anything over that figure is regarded as a risk to human health.”
Skeptical Science, advertised as “getting skeptical about global warming skepticism,” posted recently on the question: Is CO2 a pollutant? Interestingly, they made the point that carbon dioxide (CO2) is not a pollutant in any sense of the word. Yes, very high concentrations in confined spaces (they provide an example) is deadly, but then so is water in a drowning. But water is not a pollutant either.

“If you had to take a life-saving medication that had to be refrigerated, would you want the energy source to be reliable fossil fuels or literally leave it to the wind and the sun?” – LTE, below
Don’t expect the Houston Chronicle editorial team, much less the conflicted, climate-religionist business editorialist Chris Tomlinson, to forthrightly explain how a once reliable grid in the Lone Start State became wounded. They will blame it on the weather (too cold, too hot). But the real story is wind and solar reliance at the expense of thermal generation, as well as central planning of the wholesale grid by regulators/politicians (ERCOT/PUCT).
I have long complained about how Houston’s newspaper of record went from biased to uber-biased on many things political, particularly climate change/forced energy transformation.…

“At congressional hearings in 1951 to provide increased wind-power funding … Putnam’s blade failure … played right into the hands of those committed to other forms of electrical production: fossil, atomic or solar.” (Wired, below)
The quest to make electricity from wind attracted entrepreneurs well before government mandates and subsidies got involved in the 1970s. As grid power, wind turbines were concept-proven in the 1880s (as were solar panels).
The article below in Wired (October 19, 2009), “Oct. 19, 1941: Electric Turbines Get First Wind was published with the subtitle: “The giant turbine in Vermont was the first wind machine to feed the electrical grid. And then, disaster struck.”
The description below pertains to the 1.25 MW Grandpa’s Knob wind turbine, which during World War II distributed electricity to Central Vermont Public Service Corporation.…
