“But Life”



[BJ] Even climate alarmists wouldn’t say pollution causes climate change. Unless of course you are conflating CO2 – a life-giving force – with dirty air, poisoned water, plastics, etc.

[GORDON] Are we really expected to believe that 0.0016% of atmospheric CO2 (plant food) is creating a devastating “climate crisis” that threatens humanity with extinction?

[ROSSC] If you think carbon is a poison to be eradicated, when every human is 18% carbon, all your policy options are scary.

[ROSSC] Of 118 known elements, carbon: bonds with the most other elements; is the 2nd most abundant in the human body; is the 4th most abundant in the universe.

Objections and Replies

(Decarbonisation) —

(Fertilization) More carbon dioxide means more fertilization—
Reply. You can have positive and negative things going at once, and it’s the net balance that matters

(Life goes on) —

(Plant Food) CO2 is plant food—
Reply. The Calvin Cycle is more complex than that.

(Pollution) CO2 cannot be pollution, as it’s what you exhale—
Reply. Pollution is best considered an activity of man, which directly or indirectly results in the addition to water, air or soil, of matter or energy which has a deleterious effect on living organisms or structures it is desirable to preserve, or which reduces the quality of water, air or soil for any subsequent use [V.S. Russell, 1974-07].


{Incompatibility} It would be hard to appeal both to the fact that CO2 is life and that it’s a trace gas. Yet they are often seen hand in hand, or one after the other. Pointing out the contradiction helps.
