Are We Reaching " Limits to Growth" is more of a scientific paper than an opinion piece so be sure that the radical right would attack it if they new about it. What it does is say that even without climate change things are going to get bad because we don't have enough stuff to support everyone who wants to live like us. Oops, sorry what we are doing is unsustainable so everyone is going to suffer. The only question is when and is the financial disaster actually the precursor that announces we have reached that point. The author is an actuary, who is someone who crunches numbers to let the insurance companies know how much to charge for what they are selling and still make a profit.
