Wikipedia:Articles for deletion/Coherent catastrophism (2nd nomination)
I changed my mind since the last debate. I'm also the one that curated the new article. Nothing in  says that notable minority theories shouldn't have articles, suitable written with care to sources and POV. The previous article was written by an advocate, this one is apparently written by a less involved editor. Some secondary/tertiary sources to consider: https://books.google.co.uk/books?id=4gnumbZdVqEC&dq=coherent+catastrophism&source=gbs_navlinks_s Impact!: The Threat of Comets and Asteroids 1997 Gerrit Verschuur; https://books.google.co.uk/books?id=VQbTBwAAQBAJ&dq=coherent+catastrophism&source=gbs_navlinks_s Controversy Catastrophism and Evolution: The Ongoing Debate 2012 Trevor Palmer; https://books.google.co.uk/books?id=IIJ8AgAAQBAJ&dq=coherent+catastrophism&source=gbs_navlinks_s Physical Geography: The Key Concepts 2009 Richard Huggett. There are dozens more books at least mentioning this term, quite a number that discuss it in detail. A quick browse also shows up a number of academic papers by authors other than the obvious four, not necessarily advocating the concept but discussing it
