Prologue: This essay is a follow-up to two previous essays on the topic of the usefulness of trend lines [trends] in prediction. Readers may not familiar with these two essays as they were written years ago, and if you wish, you should read them through first:
- Your Dot: On Walking Dogs and Warming Trends posted in Oct 2013 at Andy Revkin’s NY Times Opinion Section blog, Dot Earth. Make sure to watch the original Doggie Walkin’ Man animation, it is only 1 minute long.
- The Button Collector or When does trend predict future values? posted a few days later here at WUWT (but 4 years ago!)
Trigger Warning: This post contains the message “Trends do not and cannot predict future values” . If this idea is threatening or potentially distressing, please stop reading now.
