Spencer Weart takes us on a journey into the past. In The Discovery of Global Warming, Weart provides a history of the science that has now come to be known as Anthropomorphic Global Warming (AGW), or more simply, man-made climate change. And in doing so he demonstrates just how robust and voluminous is the scientific case for human induced climate change.
He begins by recounting the early discoveries by such well-known names as Joseph Fourier, Guy Stewart Callendar, John Tyndall and Svante Arrhenius. Lesser known but also providing significant contributions to the developing science include such scientists as James Croll, Vladimir Verdansky, Charles Greeley Abbot, Milutin Milankovitch, Gilbert Plass, Hans Suess, David Keeling and many others. As he takes us through the years in come names such as Roger Revelle, Wally Broecker, J. Murray Mitchell, Ed Lorenz, and on to names more familiar to us in the modern day like Stephen Schneider, James Hansen, Gavin Schmidt and Michael Mann. In all, Weart reviewed a thousand studies and says that each study has 10 more like it and 10 more beyond that.
Weart’s narrative gives us a sense of the trials and tribulations of early scientists trying to make sense of myriad observations as they tested hypothesis after hypothesis. Was the Earth warming or cooling? What influences were there from sunspots, volcanoes, aerosols and particulates? How to deal with uncertainties and feedback mechanisms? We see how the science developed piece by piece in fits and starts as scientists first worked on the periphery of fields tangential to their own, then eventually realizing that the growing awareness of climate was inter- and multidisciplinary. All of these questions being addressed as technology advanced from doing calculations by hand through early computers to the supercomputers used today. From simple measurements using thermometers to satellites that scan the globe day and night.
As the case for man-made climate change grew there became a need for an way to synthesis the thousands of studies into a cohesive summary of the state-of-the-science. And so the IPCC was born. As more data came in and was compiled the conclusions moved from “discernible effects” to “unequivocal warming” and “very likely” (90-99% certainty) that is was being caused by humans. Data since the last report has not only made the case for a human cause even more certain, the rate and magnitude of change is even greater than previously thought.
Anyone interested in global warming/climate change would do well to read this book. It provides a valuable history of the development of the science, and demonstrates without a doubt the robustness of the scientific consensus that the planet is warming and that human activity is the main contributor. As Weart himself says, “the few who contest these facts are either ignorant or so committed to their viewpoint that they will seize on any excuse to deny the risk.” The science is unequivocal; whether we act is our choice. A choice that has major ramifications for our future and the futures of our children and grandchildren.

One would think the book’s subtitle “The speech that made Abraham Lincoln President,” would set up an unattainable expectation of greatness. After all, how could a book hold a candle to a great speech? Or perhaps the speech wasn’t so great after all and the author merely wanted to sell more books. And yet, I was wonderfully surprised to see that this really was an exceptional book about an exceptional speech.
Vote Lincoln! The Presidential Campaign Biography of Abraham Lincoln is a 2010 annotated version of the first full biography of Abraham Lincoln published in 1860. Ostensibly written by John Locke Scripps, publisher of what would become the Chicago Tribune, much of the text was actually ghost written by Abraham Lincoln himself. Intended as a campaign biography, the book provides a revealing look at how Lincoln viewed his own life to that point.
On November 3rd, join me and a cast of artists, writers, and filmmakers at the Chester County Library, Exton, PA for an extraordinary multimedia Tesla event. Sponsored by the Tesla Science Foundation, there will be presentations on “Why Nikola Tesla Matters” and how Tesla has been an influence in Books, Film and Art.
Am I Making Myself Clear? A Scientist’s Guide to Talking to the Public is a much needed book for scientific and non-scientific communities alike. Written by science writer (and former New York Times editor) Cornelia Dean, the book makes the case that scientists need to make “their work more accessible to the media, and thus to the public.” This doesn’t come naturally to most scientists, and so the book gives some practical tips on how scientists can accomplish this goal.
