It is becoming increasingly obvious to me that the issue of climate change has taken an ugly turn. See my previous blog entry. After reviewing the issue of Climategate very carefully, I have come to the following conclusions.
- The behavior of the scientists involved in the matter was indeed unethical and they should be disciplined over it. The head of the CRU, Phil Jones, should resign and he and other staff members, such as Keith Briffa, should be stripped of their credentials. So should Michael Mann, who is not a staff member of the CRU but was heavily involved with it, as the stolen e-mails from the CRU make clear.
- The entire field of dendroclimatology (the process of determining past climate from tree rings) has been thrown into disrepute and should no longer be regarded as a critical support for the man-made global warming hypothesis. And the “hockey stick” graph that was a product of it is no longer credible enough to be anything beyond a speculation based on questionable interpretation of data.
- Efforts to combat global warming, at least for the next few years, should be limited to voluntary efforts by the people. Government coercion opens a big can of worms, especially when the science of climate change is so uncertain.
- Even in the absence of evidence from tree rings, the evidence for the man-made global warming hypothesis remains strong, though not as compelling as I previously thought.
- Even if there were NO evidence for global warming, or even if climate change of any kind was not an issue in science, it is imperative that we gradually stop using fossil fuels and build a new energy infrastructure that will be based entirely on renewable and non-polluting sources. Otherwise, the days of our modern technical civilization are numbered.
That is all for now.
