We have readings from satellites available showing temperature changes consisting with increased greenhouse gas concentrations.

We also have data for historical temperatures going back hundreds of millions of years.

There appears to be tons of evidence. I would assume those with the PhD's, etc, in climate science would be using appropriate measurements.

Predictions, obviously are a somewhat different matter, but empirical measurements are there by the bucket load.

It's far from uncommon for predictions and measurements to be refined. Indeed it's the point. I would have been far more perturbed if the paper hadn't been released, or science as a whole rebuffed it, rather than reviewing it and modifying models accordingly.
