Human Activities -Nil Contribution to Warming;
No need to attribute 20th Century Warming to CO2;
In terms of Moschen et al.'s stated purpose of hoping to illustrate "to what extent human activities contribute to the recent warming trend observable at a regional and global scale," based on what types of natural climate changes have occurred over the past two millennia, it would have to be concluded that human activities have contributed absolutely nothing in the way of warming, as it was much warmer at Durres Maar, Germany, back in the "good old (High Medieval) days," when there was far less CO2 in the air than there is today.
