I am not implying it is a "pollutant", like you admitted above "Yes, there are times when we can have too much of a good thing"
is it important? Venus has naturally a heavy atmosphere and the surface temperature is 462oC. Mars has a light atmosphere and it can reach 20oC (warmest). There is a reason we are talking about trip to Mars, there is no way to survive on Venus.
Let's assume you are righty and the high levels of 200M years -150M years ago for example should be what we consider "normal" does it matter? we were not around then, our bodies and the world we built for them was not build for such high levels and temperatures.
For me it is not about what is normal or natural, if a huge planet destroying asteroid was headed to earth I would hope that we find a way to stop it oand minimize its effect.
"I am not implying it is a 'pollutant'".And yet you associate it with Carbon Monoxide poisoning and smog.
"Yes, there are times when we can have too much of a good thing.”Indeed, but how much CO
2 is too much? Which, of course, rather presupposes the increased level of CO
2 is a problem.
Is it [the level of atmospheric CO2] important?Your previous comments appear to suggest you do, hence the question.
"Let's assume you are righty and the high levels of 200M years -150M years ago for example should be what we consider "normal" does it matter?"The Medieval Warm Period is, I believe, a little more recent, hence the continuing efforts to undermine its significance.
"For me it is not about what is normal or natural."Then what is one arguing about?
