Looking at the Summary for Policymakers that you linked to, we are given measurements of [+0.6 to +2.4] W/ sq m at 90% confidence. Notice the huge interval: the interval length is three times the least value. If we'd re-scale it for 95%, or even 99% (the FDA will require that much for some drugs!), the warming disappears completely.

And this is simply the measurement part. _Predicting_ what will happen is a thousand times more difficult. If you want predictive science based on the laws of physics, look at astronomy. 4000 years ago, the Babylonians could predict astronomical events with much more precision than anything today's climatologists can predict about average temperatures.
