There's negative and positive feedback processes. On balance the positive feedback processes outweigh the negative ones. e.g. * Melting ice caps mean more heat absorption * melting permafrost releases methane * Warming oceans freeze frozen methane I'm forgetting a bunch, doing this from memory. What negative feedbacks do you believe outweigh these?
