It's a good book to get, a fairly small paperback called, Not by Fire, But by Ice, referring to a an old Scandinavian saying. He published 2 paperbacks which are shown and briefly discussed in this video. Are you familiar with Dubyne of Adapt 2030? Dubyne interviewed John Casey who wrote a few books worth learning about as well. I bought and read both of Felix's books, he died last year so it may be harder to find copies, both are interesting with many footnotes. The underwater volcano 'theory' was proven true by NASA.
