The oldest trick in the How to Lie With Statistics book is to truncate the data set. See how helpful it is to focus on the record from the point in the 19th century when official met recording began. This is the 4-minute record of the analysis of an ice core 3km in length extracted at a site in Greenland. The core extends back 120,000 years and the last 10,000 have been analysed to obtain an estimate of the ground temperature when the snow fell and turned into a layer of ice. The illustrations in the video cover the last 4000 years starting when the temperature Greenland was thought to be some 4.5C warmer than it is the present day. In this picture the pointer indicates the Medieval Warm Period 1000 years ago. https://catallaxyfiles.com/2021/04/21/how-to-lie-with-global-warming-statistics/
