Elizabeth has provided a very good explanation as to why some errors occur and why some scientists are motivated to act in unprofessional and unethical manner. I won’t reiterate what she’s already said.
However, shall we take an objective look at all the works associated with climate change that have been retracted. I haven’t cherry-picked these, I searched the database for all papers relating to climate change and look at every one of them.
• A skeptic paper promoting the economic benefits of climate change retracted.
• Paper linking climate change skeptics with conspiracy theorists retracted, apparently after objections from skeptics.
• Skeptical journal shut down following malpractice.
• Journal of Climate article showing temperatures higher in the last 60 years than preceding 1,000 years put on hold whilst data recalculated.
• Skeptical article withdrawn after significant number of errors highlighted and the authors refused to correct them. The journal subsequently listed all the errors.
• Skeptical paper questioning climate change science retracted after author reprimanded for misconduct and plagiarism.
• Skeptical article that reproduced work from the Competitive Enterprise Institute (skeptics) retracted after publishers were sued.
• Paper claiming behaviour of ants has been affected by climate change retracted as claims couldn’t be verified.
• Paper retracted after it was found to have exaggerated effects of global warming and couldn’t support the statements made.
SUMMARY
Nine papers retracted in total. One was more to do with psychology than climate change. Of the remaining eight, five were from skeptics. Of the three that supported the global warming theory one was put on hold, two were retracted.
There are infinitely more papers that support the global warming theory than oppose it, but more skeptical papers get retracted.
There’s probably no more than 500 skeptical papers, 5 are retracted – that’s 1.000% or 1 in 100.
At the absolute minimum, there’s 12,000 papers supporting global warming (this is just the number that the IPCC have referenced, there are many more besides), of which 2 are retracted – that’s 0.000167% or 1 in 6,000.
