When are we going to take global warming more seriously? Maybe when the death toll from it reaches a billion. Scientific predictions are pretty grim. My research 10 years ago told me that warming would continue for 100 years when we stop emitting carbon. 

Today we are surrounded by extinction, it will be our turn soon enough. We’ve already substantially changed the planet. The north and south poles are going, the water level rising. Perhaps soon we’ll need to build underwater cities, I’m sure there’s longer left if you’re rich. The poor are so often the worst off in any catastrophe.
