Piepgrass… you are a classic “denier”! When confronted with contradictory evidence to your chosen paradigm… your only response is to first, create a fallacious “reason” why that evidence isn’t right… in this case, “oh, the translation from German is to difficult”…then, you shut down and want to deny the individual has any merit. Do you seriously think the UN didn’t know he was doing interviews? Where is the UN rebuttal to what Ottmar told the world? give me a break!
As for the “science” of AGW (now “Climate Change” as the public has lost interest in the former). you rely on computer climate models… all failures, and deny the actual science… no wonder you come across as not having a clue!
You apparently aren’t capable accepting valid documented evidence… or of debating valid points. What good are you then?
Goodby!
