You probably read this past week this or a similar article about Global Warming, proclaiming that the Earth is the Hottest It's Been in 2,000 Years.
This is nothing more than an attempt to repackage/rehab the "hockey stick" graph that has been discredited. The article reports nothing new. They say that if you repeat a lie often enough people begin to believe it . . . which is what seems to be going on here.
We've hardly had "stable temperatures for 2000 years" as claimed by the article. Fault Lines doesn't think they have resumed growing wine grapes in England as in Roman time, but if they have, clearly for a long time they were unable to. Fault Lines is also pretty sure farming has yet to be resumed on Greenland, as was the case around 1000, but then again, the human colony there was driven out by cold after a warm period. The hockey stick graph did not show these warm periods followed by cold ones.

Fault Lines still has its doubts.
