The article is similarly data-free. The only references are to known/well-accepted figures that everyone is mentioning, e.g. the UN Intergovernmental Panel on Climate Change predictions. The so-called "climate reality no one else will dare mention" isn't really explored, and certainly isn't referenced, save for fairly spurious lines like:

> A small band of artists and writers [...] have embraced the idea that “civilisation” will soon end in environmental catastrophe but only a few scientists [...] have suggested as much.

So both the number of artists and writers, AND the number of scientists supporting this are apparently small. And, again, unreferenced.

I won't defend the commenter here directly, but their comment is certainly no worse nor less valid than the article.
