Getting depressed with fears of runaway global warming turning Earth into another Venus? Well, let me prescribe you this book for a bit of healing. Stager admits we do not know exactly how global climate change will unfold, but summons paleoclimatological evidence to argue that a worst-case scenario will not lead to anything remotely like Venus II. Yes, global warming is real and caused by primarily by human activity that generates greenhouse gases. But over a long period of time, Earth will adjust back to a state closer to the present. Unfortunately, that will take a good 100,000 years or so. But, he suggests, humankind will adapt (e.g. as Denmark sinks underwater, Greenland will green again). Left unsaid is what percentage of humankind will make it through. Also, this could and should have been a much shorter book.
