    given rate of temperature change per decade. Studies quantifying this have been around at least since the late 90s. The faster the change, the more catastrophic for life.

    Frankly, there's very little room for misjudgment at this point, maybe none. It is said that it takes 17-20 miles to stop a supertanker, likewise it is taking a very long time to change the world's CO2 emissions behavior, scores of years. And on top of this the half-life of CO2 in the atmosphere is something like 60 years.

    •  Mitigation needs to be a priority too (4+ / 0-)

      Reducing emissions isn't enough, not by a long shot. 2 degrees C of global warming is already in the pipeline, and what will be emitted even as we're cutting back will continue to raise temperatures further.

      Carbon neutrality isn't enough; we have to go carbon-negative and actively suck out and sequester carbon dioxide. It's simpler than we think: plant fast-growing plants, then after harvest or whatever sink them in the oxygen-depleted bottoms of meromictic bodies of water, lakes etc. that are divided into layers that don't mix. The Black Sea is suspected to be one such place, and smaller lakes and swamps can be found worldwide.

      We'll need some global means of managing the inevitable population shifts, adapting agriculture to the changing climate, and reforestation like our lives depend on it ... because they will.

      •  Using the biomass as a feedstock for plastics (0+ / 0-)

        Would be a profitable and permanent way to sequester the carbon, no?

        •  Plastic made from plants biodegrades (0+ / 0-)

          and that process releases carbon dioxide, just like regular rotting.

          Plant matter buried under sediment in anoxic conditions - like the bottoms of swamps - was how the coal and oil were originally created: we know that process works.

          Google "Azolla Event" - a uniquely huge and geologically brief natural example of this process - it's what fixed the Eocene Thermal Maximum that had palm trees growing at the Poles around 250 million years ago.
