Warming temperatures are melting patches of ice that have been in place for thousands of years in the mountains of the Canadian High Arctic and in turn revealing a treasure trove of ancient hunting tools...The latter two would be from the Medieval Warming Period, which despite Mann et al attempts to "contain" and claim was only localized, has overwhelming evidence it was in fact global and hotter than the present. The 2,400 year old spear tool would be from the Roman Warming Period, also hotter than the present. No mention of course in the LiveScience press release.
The results have been extraordinary: Andrews and his team (including members of the indigenous Shutaot'ine or Mountain Dene) have found 2,400-year-old spear throwing tools, a 1000-year-old ground squirrel snare, and bows and arrows dating back 850 years.
