Say, how did all the sea life survive during the Medieval Warm Period? Why didn’t all the coral die out? Was there some sort of mass die-off of sea life? Did islands tip over? Were they covered in hundreds of feet of sea rise? A paper published in The Holocene delves into the sea temperatures of that time period (Via The Australian Climate Skeptic Party)
(CO2 Science) What was done: Using ten proxy sea surface temperature (SST) records – six from the Norwegian Margin, three from the North Icelandic Shelf and one from the Scottish Margin – Cunningham et al. prepared a 1,000-year SST record spanning the period from AD 1000 to 2000, which revealed, in their words, that “the ‘Medieval Climate Anomaly’ warming was most pronounced before AD 1200, with a long-term cooling trend apparent after AD 1250.” And what did the new record reveal about the uniqueness – or not! – of the region’s late-20th-century Current Warm Period?
What was learned: The twenty researchers report that “in recent decades temperatures have been similar to those inferred for the ‘Medieval Climate Anomaly’.” However, their graphical representations (three versions of them) of the one-thousand-year period clearly indicate that the peak warmth of the Current Warm Period has actually been a couple tenths of a degree C less than that of the earlier Medieval Warm Period.
What it means: As has been found to be the case in so many land-based assessments of the relative warmth of the Medieval and Current Warm Periods, there is nothing unusual, unnatural or unprecedented about earth’s current level of warmth … although it could be thought to be somewhat unusual in that even with the 120-ppm increase in the atmosphere’s CO2 concentration that occurred over the last 1000 years, it is still not as hot now as it was back in the Medieval Warm Period.
Let’s repeat that last line:
…although it could be thought to be somewhat unusual in that even with the 120-ppm increase in the atmosphere’s CO2 concentration that occurred over the last 1000 years, it is still not as hot now as it was back in the Medieval Warm Period.
Unusual in terms of Warmist model predictions, which state that the Earth, and the seas, should be much warmer. Of course, Warmists will simply pronounce that the warming of the seas has disappeared into the deep oceans, much like with the surface warming. Why? Because shut up, that’s why. You ask too many questions, and asking questions isn’t science, ya know.
