I forget, exactly, but obviously there are no thermostats found perfectly preserved in tar pits. I think they plug in data from rocks and such to their models to "predict" what temperatures were back then. That's why it's kind of a big deal when those models prove wildly inaccurate at predicting just a few years in the future. And let's not jump too much on the science of those models as it's clearly a nearly impossible task to model. But when you use your model to pound the table and set off alarms, and then that model is proven inconsistent at best, then it makes you look like a fraud.
And of course there's a bit more serious issue with some obvious bias, even beyond the CRU scandal. When you're dealing with data like this, it's pretty easily - intentionally or not - to manipulate assumptions and transformations to get the result you're looking for. And the vast majority of research money here is not coming from people hoping that climate change is a hoax. And for obvious reasons, within that scientific community you either go with the flow or rendered irrelevant, for the most part.
Among all the other problems we have today, there's a growing issue of supposedly objectived and sound scientific research becoming politicized - we are seeing it with the FDA, the EPA, CBO, this climate stuff....Oddly enough, NASA seems to be one of the better sources as they may have some more integrity and also more insulated with their budget (or should say were).
