was there a (global) medieval warm period?

From co2science.org:

Was there really a global Medieval Warm Period? The IPCC used to acknowledge there was; but they have long since changed their view on the subject. Mounting evidence, however, suggests they were wrong to do so; and in this summary, both old and new important data from Northern Europe that support their original belief are described and discussed.

As for what was learned from this monumental effort, the four researchers say that their new temperature history “provides evidence for substantial warmth during Roman and Medieval times, larger in extent and longer in duration than 20th century warmth.” And it would thus appear to be the case that as ever more data-inclusive and carefully-analyzed studies of palaeo-temperature proxies are conducted, it is becoming ever more evident that there has not been anything unusualunnatural or unprecedented about either the rate of warming or the level of warmth achievedduring the 20th century throughout the whole of Northern Europe, which further suggests that there is likely no real-world empirical evidence for CO2-induced warming anywhere else on the planet either, which suggestion is pretty much verified by similar studies that have been conducted on other continents.

i wrote this (but not that)

It’s occurred to me that almost nothing published on this blog for a very long time is original; that is, what appears here is mostly filched from other blogs or sources. The vast majority of it concerns climate science and global warming. I am not, nor have I ever been, a climate scientist. What I’ve chosen to reproduce is simply a reflection of interest, not expertise. I’ve attempted to make clear that these entries are not mine, not original, but because I’m not really good at this blog thing it sometimes seems as though the writer were me. 

This is not the case!

For other WordPress blogs such as WUWT and Climate Etc. it is usually clear who the author is. But for other sources there’s simply a link to the original material, typically without a byline. This is a combination of ineptitude and laziness. The latter invariably produces the former. I’m working on it. I really am.
