Frida Ghitis : 50 years into climate modeling, we still don't really know what’s coming.

She says the coming decades may be far worse, and far weirder, than the best models anticipated.

Ghitis says global warming has progressed enough that scientists are noticing mismatches between some of their predictions and real outcomes.

She asks: The world has warmed enough that city planners, public-health officials, insurance companies, farmers, and everyone else in the global economy want to know what's coming next.

Models were meant to imagine what global temperatures might look like if greenhouse-gas emissions rose.

But models are, even now, less capable of accounting for secondary effects of those emissions that no one saw coming.

Some variables are missing from climate models entirely, and that this fact might change is not accounted for.
