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.
