The impact of climate change will fall disproportionately upon developing countries and the poor persons within all countries. It will therefore exacerbate inequalities in health status and access to adequate food, clean water and other resources.

There is, even today, a Flat Earth Society that meets every year to say the Earth is flat. The science about climate change is very clear. There really is no room for doubt at this point.
