This post is especially for those who aren’t sure whether global warming is real or not, whether it’s man-made or not, whether it’s dangerous or not. Let me tell you what made up my mind.
Readers may recall that not too long ago, I personally analyzed all the data in the entire GHCN (global historical climate network). I did this because Anthony Watts and Joe D’Aleo published a document claiming that the GHCN data, and the way it was processed, exaggerated estimates of how much the globe has warmed over the last century or more. They even claimed that the scientists who managed, and who processed, these data had deliberately manipulated both the data (by selectively removing or retaining data locations) and the analysis (by their methods of applying “adjustments”) to exaggerate the warming trend.
