Debunking that pesky Medieval Warming Period

| No Comments
A lot of the pro-Anthropogenic Global Warmers are saying that the MWP (Medieval Warm Period) and the following Little Ice Age were a localized weather anomaly and not an overall shift in the climate. The same temperature anomaly has been spotted in Foraminifera deposits in the South Pacific near Malaysia. Oops... From Anthony at Watts Up With That:
Another indication of MWP and LIA being global
From CO2 Science, another peer reviewed paper with a paleoclimatology reconstruction based on cores containing plankton shells, show that both the Medieval Warm Period (MWP) and the Little Ice Age (LIA) can be seen in Indonesia. In the past, critics have said these events to be �regional� implying they occurred only around Europe, due to lack of historical records in other regions of the world.

Since the Oxygen18 isotope dating method seems well proven, it would seem this study has a good basis for its claims. Even RC�s Gavin Schmidt likes it.

Co2 Science writes:
From the authors� Figure 2b, adapted below, we calculate that the Medieval Warm Period was about 0.4�C warmer than the Current Warm Period.
Heh - same temperature cycles, same years, same Climate Change. Not localized at all...
