Not long ago we asked German public radio Deutschlandfunk why they mentioned only the alarmist viewpoint of the Potsdam Institute for Climate Impact Research (PIK) in a report on the Gulf Stream published in March. The DLF replied that they indeed had reported on deviating models in the past.
PIK scientist Stefan Rahmstorf naturally detests it when the German media express criticism over his statements. In the Süddeutschen Zeitung of July 3, 1999 Rahmstorf was cocksure, claiming:
The Atlantic ocean current probably will weaken notably over the coming decades – here the simulations from various institutes are in broad agreement.”
Over the past one and a half decades that “broad agreement” has turned out to be a fantasy. The wide majority of scientists see no long-term change in the Gulf Stream. At the end of May 2015 yet another institute that refuses to follow the PIK has appeared. Oceanographer Kjell Arild Orvik of the Geophysical Institute of the University of Bergen has studied the Gulf Stream at the west coast of Norway and has determined that the ocean current has remained stable over the last 20 years. At the Forskning.no website (via WUWT) Orvik explains:
What we see is that the stream is lively in the sense that it varies both seasonally and from year to year. But when observing it over 20 years, it shows long-term stability.
Of course neither German national public radio Deutschlandfunk nor the Süddeutsche Zeitung have reported on this interesting development from Norway.
