On 8 August 2017 the Chinese Academy of Science published a remarkable . The most important news was already given by the sub-heading: The warm climate of the the past decades was nothing unusual in the context of the last 2000 years in China. Already in the pre-industrial years scientists were able to make out similarly warm periodsRemember, the excitement from Michael Mann's Hockey Stick was that it said that recent warming was unprecedented and that the Medieval Warm Period didn't exist, despite recorded evidence from the day. When new studies showed that yes, it was warmer in Medieval Europe, the response was "that's not a global study".
Man, you'd think that if the science actually were as settled as they tell us that you'd see evidence for global warming everywhere.
