[quote="mkpdavies"]Exactly. It's all so miniscule, you would hardly notice it is happening.quote]
I'd like to try to keep this to a mature and civilised conversation without the usual pejorative terms like envirofascist .
It seems to me that your chief objection to human influence is the minute contribution to the global atmosphere that results from CO2 produced by human activities. P1ssing in the sea is an analogy you have used*.
But, just because something exists in relatively small quantities, doesn't mean its influence can be discounted.
Atmospheric CO2 is about 0.04%. Human contribution is about one thirtieth of that. Say 0.0013%. Negligible? One might imagine so.
There again, an injection of 0.0013% arsenic is a lethal dose.
My point is that you can't discount very small quantities just because they are very small quantities.
