A review by John M. Repp of Michael E. Mann’s The New Climate War: The Fight to Take Back Our Planet (New York: Public Affairs, Hachette Book Group, 2021) (revised July 2022)
Michael E. Mann [The New Climate War: The Fight to Take Back Our Planet (New York: Public Affairs, Hachette Book Group, 2021)] is a climate scientist who, with colleagues, published the so-called “hockey stick” graph in 1998. It was a graph of the steep rise of carbon dioxide in our atmosphere since the industrial revolution, as seen below. There the red trend line on the right is going up and shows carbon dioxide in the atmosphere and is correlated with the rise of temperature anomalies, the green dots, plotted from the year 1000 AD. On the left side is a scale in fractions of centigrade degrees. This graph became the center of a huge controversy, but Mann survived the battles. Science has confirmed the “hockey stick”. Carbon dioxide traps heat in our atmosphere; the more carbon dioxide, the more heat is trapped, and it has been building up since the industrial revolution, when we started to burn coal in large quantities.
