Greenpeace in the IPCC: the Edenhofer Excuse

IPCC WG-III Co-Chair Ottmar Edenhofer of the PIK, Germany

It has been a recurring pattern that the most dramatic of conclusions reached by the IPCC, are shown to arise from exaggerated claims in literature put out by environmental pressure groups. The latest addition to the list is the Greenpeace-generated factoid that ‘80% of the world’s energy demand in 2050 could be met by renewable sources’ which found its way onto the IPCC pedestal.

Unoriginally one might add, writer Kyle Niemeyer in ArsTechnica paraphrases and reproduces exclusively ‘the Edenhofer Excuse’.

What is the Edenhofer Excuse?

Ottmar Edenhofer’s arguments defending the IPCC, though multifarious are plainly contradictory to each other and are easily seen to violate commonly-understood academic standards. It goes like this:

  2. the Greenpeace’s scenario was ‘just one of one-hundred and sixty four scenarios’ evaluated
  3. Sven Teske was just one of the authors of the Greenpeace scenario
  4. The Greenpeace scenario was actually performed by the German Aerospace Agency DLR. Greenpeace only just commissioned it.
