I means, something that isn’t temperature but has some form of transfer function between the proxy and real temperatures.

According to their research it worked prior to 1960 but afterwards the transfer function didn’t work anymore.

I would say, if it didn’t work after 1960, what make them think it worked in the year 1000 or 1900 for that matter.

You have to gauge the accuracy of your proxies against real temperature data. If they diverge, your proxy is invalid.

That means throw it away unless you can come up and explain the transfer function. They can’t, game over.

If I am not clear, ping me back, because this important to be clear what is going on. If we can’t explain it to each other clearly, we can’t educate the public.

Thanks.

OK, in this context, what is the "proxy" and how did they claim they were measuring it? I know you are trying to help, but I asked what the "proxy data" was and you answered using the term "proxy."
