As is generally known by those studying the most important issue of our time, the forecasts by the IPCC are on the conservative side with scientists overly cautious not to include predictions which may be perceived as too pessimistic. A new study in the Science Journal shows that actually the more pessimistic climate models are much more accurate:

It’s important to note that the IPCC estimates do not fully take into account feedback loops and tipping points. Below is an excerpt from “Imperiled Life: Revolution against Climate Catastrophe” by Javier Sethness-Castro (2012):

…A 2009 study on climate change performed at the Massachusetts Institute of Technology–less optimistic and thus perhaps more realistic, for example, than the IPCC’s reports to date regarding the prospect of achieving significant carbon emission reductions in the near future–finds there indeed to be a chance that temperatures will increase 7.4°C (13°F) over preindustrial temperatures by the century’s end, with a 90 percent chance that the temperature increase would range between 3.5°C and 7.4°C (4.8°F-13°F).(75) The study’s authors are quick to clarify that even their decidedly bleak conclusions might be underestimates, as they, like the IPCC, do not fully account for the various feedback mechanisms that could arise given catastrophic climate change. NASA’s Dennis Bushnell, for his part, estimates that the average global temperature increase expected during this century once these feedbacks have been accounted for would amount to between 6°C and 12°C (10.5°F-21°F).(76) Warming of such apocalyptic proportions would be entirely horrific: it should be remembered that it was a 6°C (10.5°F) increase that triggered the end-Permian mass extinction.(77)

Though a matter of controversy among climatologists, there is reason to fear that overheating beyond these levels could induce a runaway greenhouse effect that would give rise to what Hansen terms “the Venus syndrome,” whereby climatic change abruptly delivers Earth to a state resembling that of Venus, where life simply cannot exist.(78)…

And another two news stories from the last few days with more ominous signs of possible acceleration into climate chaos:

I’m finding it harder to carry on with blogging about reality without compartmentalizing all this grim news into some dark recess of my brain, only to be unlocked at night when I read up on this subject. I live two lives – one in the fake world that we all mill around in like zombies in order to survive… and the other in this blog researching the coming apocalypse. No wonder the Apocadocs turned to humor to deal with this stuff.
