Read here. A stalagmite from a cave in northwestern Sweden confirms that both the Medieval Warming and Little Ice Age temperatures were substantially different than our modern temperatures.
"Sundqvist et al. write that "the stable isotope records show enriched isotopic values during the, for Scandinavia, comparatively cold period AD 1300-1700 [which they equate with the Little Ice Age] and depleted values during the warmer period AD 800-1000 [which they equate with the Medieval Warm Period]." And as can clearly be seen from the figure above, the two δ18O depletion "peaks" (actually inverted valleys) of the Medieval Warm Period are both more extreme than the "peak" value of the Current Warm Period, which appears at the end of the record."

Again, the evidence keeps mounting against the fabricated IPCC temperature histories (i.e. the "hockey stick") by the infamous Climategate scientists. There is no actual evidence supporting that current tempertatures are above the Medieval Period other than those studies used by the IPCC that have cherry-picked selected data and/or heavily massaged the data using non-professional, very unusual statistical methods.
