Points of agreement

Andy Revkin suggests that there are four points most climate and energy experts agree on:

1. A big buildup of long-lived greenhouse gases will very likely influence the climate in a host of ways that could impede the journey toward a stable, prospering human population later this century.
2. Humanity's existing energy choices and habits are grossly insufficient for a population heading toward (more or less) 9 billion people seeking a decent life.
3. The planet's existing energy choices and habits will lead to an enormous buildup of greenhouse gases, particularly as large developing countries industrialize.
4. The world's industrialized countries, outside of Japan, have for decades invested a tiny proportion of wealth (public and private) in research and development on energy technology compared to nearly all other technological and scientific endeavors (from building better weapons to fighting cancer).

I don't know about point 4, but I'm willing to take his word for it. The first three points are enough to make it clear that it's way, way past time to stop arguing about whether we are changing the climate and to start arguing about what we are going to do about it.
