The White House loves the parallax scrolling. http://nca2014.globalchange.gov/ but more to the point: we're hosed. Totally, utterly, completely hosed. It's wonderfully refreshing to read a major government publication with the atmosphere and tone of my daily visits to Desdemona Despair. The report mentions in passing that by 2050 we'll have 9 billion people on the planet. They could have stopped there and ended the report, which I nevertheless encourage everyone to read in its entirety; it's written at a 6th grade reading level to make it more accessible to the Tea Party denial types. If we have 28% more people on the planet by 2050, that means in 36 years, our greenhouse gas emissions problems will be 28% worse than they already are if the global distribution of per capita resource consumption remains roughly what it is now. But a billion Chinese and a billion Indians don't like the status quo and would like to create a middle class the size of Europe and North America combined with per capita resource consumption on par with Europe and North America. If we are going to successfully mitigate and adapt to climate change, we have to overcome that 28% population growth hurdle as well as address current levels of resource consumption and the desire of the developing world for middle class propserity. And we've already dug ourselves into a deep pit of despair. 36 years from now, the per capita cost of actually doing something meaningful about climate change will be too enormous for anyone to contemplate willingly. It's already too enormous. That's why we're hosed. To date, the most straightforward and obvious way to stop and, over the long term, reverse anthropogenic climate change would be to reduce the human population to 1 billion and keep it there indefinitely, until we evolve into something else or in the extremely unlikely event that we figure out interstellar space travel and begin colonizing other worlds. The population collapse is coming regardless. Ocean acidification alone is going to revolutionize the entirety of marine biomass in a way not seen since the K-Pg extinction event. Once that process is fully underway, the prospects for feeding 9 billion people will be bleak. Welcome to the Anthropocene.
