I'm quite certain you have no such quote from any "leading" climate scientist but it is common knowledge that not all experiments can be repeated or can be reasonably be done. Some obvious examples are an experiment that costs an enormous amount of money to conduct or one that requires a specific configuration of the universe (say, an eclipse or an occultation). The majority of climate science experiments involve processing specific data sets. Repeating the processing is easily done. What sort of experiments are you concerned about here?AGW theory, who's leading scientists say that their experiments need not be repeatable.
It takes a special breed of stupid to still believe what they say.
