I've never claimed that trace amounts can never be harmful in any
context whatsoever. That is your construct, and your strawman
argument, not mine.
The reality is in the nature of the substance that we are discussing.
CO2 is not an equivalent to sarin or cyanide or zyklon B or anthrax or
anything else. CO2 is CO2. CO2 is not even comparable to CO. Two
entirely different compounds. Completely different properties.
And in the context of what CO2 is, and it's role in the atmosphere,
and in life in general, 380 ppm is actually low. In terms of
usefulness to animals and plants and historical levels. If it goes
much lower than 150 ppm, all life on the planet is in danger. That is
on the down side of atmospheric values. On the up side of atmospheric
values, planst love CO2 at levels up to 80%, and animals do not suffer
any problems until CO2 levels reach around 5% of the atmosphere. That
is literally thousands of times higher than what we have now. And if
we assume CO2 levels going up at the current rate in a linear fashion,
which is impossible, levels will not be anywhere near the 5% levels
for thousands and thousands and thousands of years.
The increase we have seen in the last millenium has brought CO2 levels
to approx 380 parts per million. That is about 4 one tenths of one
percent. The actual total increase since the late 1800's is about one
one tenth of one percent (100 ppm). And man's actual ascribable
influence is around 14 ppm. 1.4 one hundredth of one percent. Trace.
Now feel free to explain again how trace amounts of CO2 can have more
than a trace amounts of effect on the globes climate.
Cites will be required.
