Is Europe about to experience famine? New research shows that we may well be on the edge of a civilization-destroying climate change event. And we must do something about it.Most Americans are at least vaguely familiar with the Irish Potato Famine of 1845, but few could tell you much at all about the much larger planet-wide famine of 1816. But Europeans can tell you all about the "Year Without a Summer,” because their news sometimes references it in the context of global climate change. It’s one of the deepest fears of many Europeans.
