In graphs relating to climate data, both sides of the debate routinely use lines to highlight trends in the data.
This is inappropriate. The climate is a complex system that is affected by may cyclical variables. Linear trends dont occur, because the trend is always cyclical. the measurements will not rise forever, or fall forever.
Those who say humans are causing climate change and warming, highlight the linear trends and say that the trend will continue linearly. This is fraud.
Those who appose the view that humans are causing warming, also use linear trends to highlight the errors in the data presented by the warmists. It would be good to use curves instead of lines, as it would be more accurate and still show the fraud of the warmists.
