Separating Science from Non-Science When it Comes to Climate Change

phony baloneyAs noted last Friday, The Dake Page has recently begun a weekly series exposing climate denialism. This week the site takes a look at how you, the interested and informed citizen, can “separate the actual science from the pseudoscience, or worse, the crock.”

One way is to employ what professional skeptic Michael Shermer calls the “Baloney Detection Kit.” In the video that follows, Shermer lays out ten questions everyone should ask themselves as they evaluate various claims.

After you watch the video, go here to finish reading how these apply to man-made climate change.The Dake Page publishes a new post every Thursday morning. You can read archived articles here. Links to The Dake Page will be periodically posted on this Science Traveler site for those who are interested.

Science Traveling Through Climate Change Denial

5 stages of denialMan-made climate change has been described by scientists and policymakers as one of the greatest challenges of our time. It has also been called a hoax by fossil fuel industry lobbyists and oil-state politicians. The fact is that human activity, primarily the burning of fossil fuels and the release of carbon into the atmosphere and oceans, is warming our planet. This has both short- and long-term ramifications for economic, political, ecological, and social structure. No amount of denial will stop that, only action to reduce carbon emissions.

The Dake Page has been reporting on science issues for many years and recently began a series exposing climate denialism. The goal is to discuss the tactics and tall tales of those who deny the science of climate change. Links to The Dake Page will be periodically posted on this Science Traveler site for those who are interested.

The first in the current series relates to an internet communication campaign by a website called Skeptical Science, and the resulting “rebuttal” by climate science deniers. Others in the series can be found at this search term: exposing climate denialism. Earlier posts on The Dake Page are also relevant to the discussion.

David J. Kent is the author of Tesla: The Wizard of Electricity and Edison: The Inventor of the Modern World (both Fall River Press). He has also written two e-books: Nikola Tesla: Renewable Energy Ahead of Its Time and Abraham Lincoln and Nikola Tesla: Connected by Fate. His next book, Lincoln: The Man Who Saved America, is scheduled for release in summer 2017.

Book Review – The Discovery of Global Warming by Spencer R. Weart

Spencer Weart The Discovery of Global WarmingSpencer 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.
