Read here and here. German climate scientist Stefan Rahmstorf has made a name for himself by predicting incredible sea level rises due to global warming. These "predictions" of course are based on computer models, which history tells us are completely worthless when predicting the chaotic climate of Earth.
Regardless, this hasn't stopped Stefan from avidly seeking the media limelight by announcing scary sea level increases generated by the dubious models.
Unfortunately for Stefan, the actual facts are always the proof that determines if model predictions have real-world value. The latest data, from the premier sea-level measuring program in the Pacific managed by the Aussies, totally shatters the Rahmstorf prediction that global warming is causing accelerated sea level rise trend. As the chart below indicates, there is no trend of sea level rise acceleration across the Pacific.
And it's not just this specific data that proves Rahmstorf is incompetent at his day job - multiple studies are making similar findings. Yet the media keeps quoting the IPCC's 'wrong-level' Stefan. Go figure.
