From the conclusions:
The record shows a substantial and long-term warming during the Roman Warm Period (~350 BCE – 450 CE), followed
by variable bottom water temperatures during the Dark Ages (~450 – 850 CE). The Viking Age/Medieval Climate Anomaly (~850 – 1350 CE) is also indicated by positive bottom water temperature anomalies, while the Little Ice Age (~1350 – 1850 CE) is characterized by a long-term cooling with distinct multidecadal variability. When studying the Gullmar Fjord bottom water temperature record for the last 2500 years, it is interesting to note that the most recent warming of the 20th century does not stand out but appears to be comparable to both the Roman Warm Period and the MCA.

Does anyone here know how their methods stack up?
