    More confirmation of “background” science. (The denialists are out in force in the comments section) “In prehistory, CO2 and warming went in lock-step” http://phys.org/news/2013-02-prehistory-co2-lock-step.html
    Add permafrost thawing and we have a pretty convincing recipe for disaster.

    They don’t know about the carbon cycle

    The reality of all of that previously tied up carbon freed into the atmosphere scares the crap out of me. It should scare them too.
