The question about the MWP that is still outstanding was: was it global?
That's what the MWP project is all about.
See, here's how it worked.
Let's say in 1994, some guy used xxx temp reconstruction method and found that it was way warmer during the MWP than now in Greenland. He presents his data, gets it peer reviewed and published.
Then, someone says, "Hey, look, the MWP was real". And then the global warming zombies say "Sure, in Greenland, but not everywhere - no MWP"
So, then in 1997, a bunch of other guys use xxx temp reconstruction method and found that it was way warmer in the MWP in New Zealand. He presents his data, and it gets peer reviewed and published.
Then of course, the global warming believers say, "Sure, it was warmer in New Zealand, but not everywhere - no MWP".
And then, in 1998, in China.....hopefully you can see where this is going.
For years after the hockey stick fraud, those who perpetrated it had to DENY the MWP, and there excuse was always, "Sure, HERE it was warmer, but it wasn't global"
Enter the MWP Project. They compiled all the peer reviewed papers that had been published and started making a map of all the studies, literature, etc etc that showed the MWP was warmer in certain parts of the globe.
Eventually, when they had compiled enough info that said it was warmer during the MWP in North America, and South America, and Asia, and Australia, and everywhere else in between, they came to the conclusion that the MWP was much warmer than today, and it was much warmer just about everywhere. (which incidentally was the OVERWHELMING CONSENSUS of science up until the hockey stick fraud).
Not only that, but we have writings dating back to that time, and the vast majority of those at-the-time-current writings suggest a world a lot warmer than today.
Now a serious question, since you specifically asked if it was global:
If you really wanted an honest answer to that question, wouldn't the way the MWP Project did it be EXACTLY how you would want it done? Taking work from hundreds of non-coordinating sources and non-agendas sources that had already passed peer review?
And did you ever ask yourself this: Why isn't there a website that has hundreds of peer reviewed papers covering areas from all over the world that show that it was cooler during the MWP? You don't have to ask yourself, I'll tell you: because they don't exist.
Look, you can see it on this thread. The general response to the findings of the MWP is NOT, "hey, here's the peer reviewed science that disagrees", but rather, "Boo! Funded by Exxon" "Boo, crazy deniers".
That in itself is pretty telling. I mean, IF you want to know the truth.
