  •  Non-linear trends (11+ / 0-)

    This is the look of a typical non-linear shift in climate change. Henri Poincare observed that nature rarely (never?) acts linearly, despite our every temptation to do so. Chaos theory is another term to mind.

    Temperatures will not move in a linear direction, they will at some point jump sharply upward, then level, then jump with even faster velocity.

    Sea level rise will not just steadily increase, there will be pulses of abrupt sea level rise over the centuries as the WAIS fades back and leaves behind land.

    We've messed up. We're decades past the point when we should have reversed course. Now we're just looking at changes happen with the same immediacy as a supernova appearing to burst in the present, even though the star had already gone supernova millions of years ago. Not the best analogy I guess, but the idea here is that we're seeing changes to the climate from accumulated carbon emissions going back decades all the way to present. To change now will not prevent further locked-in warming and sea level rise, but will help decelerate what could already be very dangerous.
