Sir Peter Gluckman, scientific adviser to NZ prime minister John Key, recently published a discussion paper entitled Towards better use of evidence in policy formation (pdf). It’s an interesting read for anyone who has ever noted the sometimes large discrepancy between political dogma and policy outcomes. Sciblogger Peter Griffin went so far as to describe it as “possibly one of the most important [papers] he has released thus far”.
Over in the land of the Climate Clueless™ however, Richard “Climate Conversation” Treadgold has taken Gluckman’s paper as a cue to demand evidence of climate change. Treadgold appears to have forgotten that one of Sir Peter’s first acts following his appointment was to review the evidence and issue a statement on the subject, and is perhaps still smarting from Gluckman’s comments on climate denial last year. He therefore issues this stern challenge:
I would remind Sir Peter that evidence is required to establish the following key factors in the global warming debate — evidence that has not surfaced so far. We have been looking for evidence to show:
- The existence of a current unprecedented global warming trend.
- That the greenhouse effect is powerful enough to endanger the environment.
- A causal link between human activities and dangerously high global temperatures.
- That climate models have a high level of skill in predicting the climate.
- A causal link between atmospheric levels of carbon dioxide and global temperatures.
- A causal link between global warming and the gentle rise in sea level.
Time to play some whack-a-mole…
