Hi combjelly; Re: "The MWP/MCA [Medieval Warm Period / Medieval Climate Anomaly] was an anomaly. It wasn't a global phenomenon. Ditto the Little Ice Age."
Sigh. Science keeps moving on but not you. You're mouthing the truths of the late 20th century.
Let me put some context to this argument. When Michael Mann created the "hockey stick" back around 1998, the geologists knew it was wrong because it didn't show the MWP. Global warming fanatics like you took the alarmist viewpoint that he was right and that thousands of geologists were wrong. Since there weren't global records for the MWP Mann's argument was that the MWP was only a local phenomena, western Europe only.
The political part of the alarmist message of the time was that "the science is settled". Therefore you assumed that the things you learned in 1998 about the MWP were "settled". There was no reason for you to learn anything further. What was known in 1998 was the truth. It would remain settled science forever.
Wrong. The geologists won that battle. The alarmists were forced to retreat. You don't know about this because you only read extreme left wing news sources that are in deep denial about science. That is, they trumpet scientific results only when those results completely agree with them. You're basically a modern day anti-science Luddite.
I'm going to link in a peer reviewed paper published in 2012. The first sentence of the paper is: "Proxy temperature reconstructions indicate that the Medieval Climate Anomaly (MCA, roughly 950–1250 AD) was warm in many parts of the world (e.g., Hughes and Diaz 1994; Mann et al. 2008, 2009; Esper and Frank 2009; Frank et al. 2010; Ljungqvist 2010; Graham et al. 2011)."
Now "warm in many parts of the world" means that is was global. If this were any old paper you'd remain in denial about it. I'm sure you're thinking "oh that's just one of those denialist papers that snuck by peer review." Wrong. Here's the paper:

Go read the article. You'll find that you're wrong about the Little Ice Age (LIA) as well.
Re: "You can argue with the history all you want. The fact of the matter is that most Americans did not hear the term "climate change" until the Bush administration started to use it."
Maybe most Americans learned the term from the Bush administration but the Bush administration got it from scientists. Here, read the NASA explanation (and send them a letter if you don't agree, LOL):
