Forecasting the weather 30-year in the future.

Again, from Nature, a reminders that thirty years ago Climate Scientist J.S. Sawyer predicted that with the expected 25% increase in CO2 in the atmosphere, the average T on the planet surface would go up 0.6 Celsius. The observed value has been 0.5. A remarkable prediction, especially considering that at the time we were thought to be heading into another ice age (which we would be, were it not for man's action, I guess). So, very few people gave credit to the thought of an inversion.

So, now what?
