The Extinction Survey
The Extinction Survey
There is a survey currently running on the Doomstead Diner, which asks people to make specific, numerical estimates about the timing of human extinction. It is inspired by the work of Guy McPherson, who has amassed much scientific evidence that points to very major climate disruption occurring over the next 2-3 decades, caused by multiple runaway positive feedback effects, such as Arctic methane release. Guy’s conclusion is that these changes will mean that the Earth will no longer provide a habitat for humans, leading to near-term human extinction. His reasoning, as far as I have been able to piece it together, rests on a supposition of time-invariance: the planet will be warmer than it has ever been in human experience; therefore, no humans will survive. This is far short of a proof.
I see two ways to provide a proof.
The first is based on proving the existence of an extinction mechanism. For example, humans don’t function well when atmospheric CO2 concentrations exceed 5000ppm, which cause dizziness, fainting spells and asphyxiation. Right now they are around 400ppm, going up by 2ppm every year. If that stays on track, this gives us 2300 years. However, there is not enough fossil fuels to keep burning at the same rate for another 2300 years. I am not aware of any straightforward bit of math that would conclusively demonstrate the impossibility of our continued existence.
The second is to make an inventory of all possible human habitats, and lifestyles to go with them, and then demonstrate that none of these habitats will be available in just a few decades. This is tricky, because it’s so easy to pass over some small niche that may remain survivable far into the future, and all it takes is one of these to narrowly avoid extinction. An examination of mitochondrial DNA showed that at one point the human population dwindled to just a handful, yet we are still around—numbering in the billions! Extermination is hard—ask any exterminator—and extinction is even harder.

The Limits of Propaganda
The Limits of Propaganda
As Paul Craig Roberts has recently reported, the US government is in the process of launching an all-out war on truth. Those who express views contrary to the party line out of Washington will be labeled a threat. Eventually they may find themselves carted to one of the concentration camps which Halliberton (Dick Cheney’s old company) has constructed for $385 million. But that may take a while. In the meantime, we can expect lots of other, less dramatic developments. Indeed, some of these are already happening. Here they are, listed in order of severity.
1. Self-censorship. Those who have previously tried to get the truth out no matter what become more reticent and prone to equivocation when reporting on “hot” issues.
2. Topic-avoidance. They start avoiding certain “hot” issues that they feel are most likely to get them into trouble.
3. Response to harassment. A few incidents of mild official harassment cause certain blogs to start watering down their content, or pulling down content in response to harassment.
4. Blacklisting. The officials start censoring content on a case-by-case basis, blocking or shutting down certain internet sites that they consider seditious.
5. Blocking communications. The officials start dealing with the “hard cases” of uncooperative individuals who remain, shutting down their communications by disabling their cell phones, shutting down internet access, and by imposing travel restrictions so that the “hard cases” are forced to remain in places where they can be watched.
6. Detention. Those found to be truly uncooperative, who try to circumvent the restrictions, are rounded up and shipped off to the above-mentioned camps.
