Man-made climate change is definitely happening: carbon dioxide is a greenhouse gas (we have known this since the 1880s) and we are adding carbon dioxide to the atmosphere in very large amounts. Both of these are indisputable. If the poles are reversing, that does not negate man-made climate change. It does the opposite: it makes man-made climate change that much worse. It makes it even more important that we reduce atmospheric carbon, and it gives us a much shorter timeline to do it in.
