Good source of climate change data

[popeyespappy]

Lessons learned so far in climate modeling class - it is so far impossible to model small phenomena past a few weeks and the best we can do with the massive scale of El Nino/Southern Oscillation (ENSO) is predict up to six months. But even that becomes iffy, as minor differences in initial conditions diverge completely ~6 months as a prediction.

The more general you are with climate, the chances that you are 'correct' goes up, while precision drops like a rock.

That’s what Hansen says. It’s a lot easier to predict long term climate change trends on a global scale than it is to predict relatively short term local weather trends.
