What happens in 15 years?

  The rate of temperature change increases. Siberia thaws and releases massive amount of methane. The Gulf Stream slows down and throws a critical regulator of temperature in the Western world into disarray. (According to news reporting earlier this week, the first signs of it slowing down are starting to appear.) Positive feedback loops are powerful things.

  Either everything changes, or stays the same. That's why radical climate measures are a tough sell.

    It's quite clear that things won't be staying the same. What precisely happens, however, seems to be up in the air. I'm not a climate scientist, but some things to consider: There was recent research showing that the Greenland ice sheet is probably not as stable as previously thought.

If those change things will get "interesting" in many places.
