You should look into that before you call me a "conspiracy theorist" again. Why is it that a public scientific institution can't release data for an academic study but a bank will?
Because they don't own the propriety weather station data. If you're actually denying that proprietary data exists, then yes, you are definitely a conspiracy theorist.
Since anyone can reproduce the same results with freely available non-proprietary data, that particular conspiracy theory doesn't seem to have a rational point. But it does have an irrational point. They don't care about some supposed lack of data. They care about having an excuse to fabricate a conspiracy about how those awful scientists are hiding data.
If conservatives applied the same rule to IPCC data that they apply to their own, they wouldn't even be considering it.
This isn't a "conservative-liberal" issue, it's a scientific fraud issue.
