Denier? I did not deny that immigration has been a source of some problems in the USA and especially in Europe recently. But I did deny that solving those problems would be relevant for finding a solution to global climate change due to human use of fossil fuels and other human activity. As I said, climate crosses all borders even when people do not. The lack of any connection that I see between solving these two problems is why I said you were changing the subject.

However, when I am wrong, I am willing to learn. Could you please explain to me exactly how better managing the world's immigration problems would halt or reverse climate change?

Thanks.
