Phil Torres has a new book due late this year from Pitchstone: The End: What Science and Religion Tell Us about the Apocalypse. You might want to watch out for it - I wrote a foreword for the book, having been provided with a copy of the manuscript. I wouldn't have done this if I didn't think it was a terrific book.
Torres has done a good job of this, discussing planetary and civilizational risks and what we might be able to do about them. His point about religion is not that any of it is true; it's that the world is full of apocalyptic ideologues who not only believe prophecies of the last days, but are actually prepared to do what they can to bring about Armageddon. He goes into this at considerable and fascinating length.
