Climate junk science: We're all supposed to drastically alter our lives and our economies because of a two-degree limit that was "plucked out of thin air"?

The (un)sustainability of all climate all the time | The View From Here

It was thanks to Germany’s Schellnhuber that the “dangerous” 2°C first entered the propaganda scene. As he told Der Speigel‘s Marco Evers, Olaf Stampf and Gerald Traufetter in April 2010:

a group of German scientists, yielding to political pressure, invented an easily digestible message in the mid-1990s: the two-degree target. To avoid even greater damage to human beings and nature, the scientists warned, the temperature on Earth could not be more than two degrees Celsius higher than it was before the beginning of industrialization.

Rarely has a scientific idea had such a strong impact on world politics. Most countries have now recognized the two-degree target. If the two-degree limit were exceeded, German Environment Minister Norbert Röttgen announced ahead of the failed Copenhagen summit, “life on our planet, as we know it today, would no longer be possible.“

But this is scientific nonsense. “Two degrees is not a magical limit — it’s clearly a political goal,” says Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research (PIK). “The world will not come to an end right away in the event of stronger warming, nor are we definitely saved if warming is not as significant. The reality, of course, is much more complicated.”

Schellnhuber ought to know. He is the father of the two-degree target.

“Yes, I plead guilty,” he says, smiling. [emphasis added -hro]
