There's plenty to read on the topic no matter where you look, from news articles about California's carbon-emission legislation, to stories about creeping dead zones in the ocean, technical papers concluding the "likelihood of acceleration of ice sheet disintegration and sea level rise", or innumberable more discursive pieces like Bill McKibben's Worried? Us? essay in Granta, or his article a couple of weeks ago in the Boston Globe. Or books only implicitly relevant, like Douglas Erwin's surprisingly readable Extinction : how life on earth nearly ended 250 million years ago.
