isaacschumann says: "...i profoundly disagree with your assertion that we have only a brief window to act before things spin out of control, there is absolutely no scientific basis for tipping points and the like." Since we know there actually is a scientific basis for human caused GHG climate disaster, and we realize individuals with your point of view can't be convinced by scientific evidence, we choose to stop trying to convince you. We will stick to convincing swing voters instead, people in the middle of the political spectrum. Extremists are being marginalized daily as their spokespersons rant. Feel free to further this cause. It helps get the majority to vote for a climate curing, job creating green energy and ag revolution. We will continue to emphasize economic stability and financial security by advocating independence from imported energy and chemical fertilizer (yes, that's right, ammonia fertilizer is now brought in on ocean going tankers from Russia).   more »
