“In a paper published in the Journal of Quaternary Science, Esper et al. (2014) … combined portions of each to produce a new-and-improved summer temperature history for northern Europe that stretches all the way ‘from 17 BC to the present.’ And what did they thereby learn? … [That] history depicts ‘a long-term cooling trend of -0.30°C per 1,000 years over the Common Era in northern Europe’…. Most important of all, however, they note that their temperature reconstruction … indicate[s] that ‘conditions during Medieval and Roman times were probably warmer than in the late 20th century’…. And so we continue to collect ever more real-world evidence for the fact, that there is nothing unusual, unnatural or unprecedented about the Earth’s current level of warmth.”
