Lewis Page summarizes some recent findings published in the peer-reviewed Earth and Planetary Science Letters journal:
More peer-reviewed science contradicting the warming-alarmist “scientific consensus” was announced yesterday, as a new study shows that the well-documented warm period which took place in medieval times was not limited to Europe, or the northern hemisphere: it reached all the way to Antarctica.
The research involved the development of a new means of assessing past temperatures, to add to existing methods such as tree ring analysis and ice cores. In this study, scientists analysed samples of a crystal called ikaite, which forms in cold waters.

A proper temperature record for Antarctica is particularly interesting, as it illuminates one of the main debates in global-warming/climate-change: namely, were the so-called Medieval Warm Period and Little Ice Age merely regional, or were they global events? The medieval warmup experienced by northern Europeans from say 900AD to 1250AD seems to have been at least as hot as anything seen in the industrial era. If it was worldwide in extent that would strongly suggest that global warming may just be something that happens from time to time, not something caused by miniscule concentrations of CO2 (the atmosphere is 0.04 per cent CO2 right now; this figure might climb to 0.07 per cent in the medium term).
And notice there is a deafening silence on the issue from the main stream media.
