test 2 (sorry, stragne things happening here)

There is currently much uncertainty in how big of a component man-made global warming is and climate models thus far have been poor predictors.

Now, this for example is wrong. There is not much uncertainty about man made part in the change. The really really careful ones say 70%, others say 100%. But if we - as humanity - don't change our behavior, that just means that the earth takes a bit longer (or not) before the climate change has really serious results.
And climate models have been quite good predictors. In fact the real curve is very close to the "most likely prediction" ones.
But yes, of course, you can find extremely diverging models, because they all use different estimates.
There is no perfect model that could predict Trumps win in the US elections in the year 2000 - but that will still be a big influence in global climate. Here again: The models based on "we don't do as the scientist say and make only small efforts" is quite matching with real earth results.
