Richard,
If there indeed exists a bias in the peer review system then that should be addressed by making public the unfair referee reports.
I'm not familiar with climate science, but I know that in physics such bias is rare. I know of a few cases were people have made public their referee reports to expose unfair/bad reports,
see here and here. If you just raise objections about the way climate scientists have collected and analysed their data, then it is difficult for us (non experts in this field) to judge if these objects are indeed relevant. You can always raise objects against objections etc. etc. etc.
If you have an exchange between experts then it is easier for people like me (non experts, but qualified scientists in other fields) to see if you have indeed valid points which are not taken seriously.
