Howe, Joshua P. 2014. Behind the Curve: Science and the Politics of Global Warming. Seattle and London: University of Washington Press.
Review by Michael Beach
There are two curves that give reference to the title of this book. The first was developed by Charles David Keeling in 1958. This was his projection linking increased carbon dioxide levels measured in the atmosphere with increased temperatures globally. As the book notes, much of the science of what today is called climate change is connected in one way or another with that original dataset and its resulting graphical curve. Politically, being behind the curve in this sense relates to actions taken or deferred by various national and international organizations.
The other curve Joshua Howe is more focused on, is about the assumptions that are made within the scientific community. Essentially, many scientists find data such as that developed by Keeling, then share that data assuming it will speak for itself and everyone will recognize the need to act. This thinking is linear in that science ‘discovers’, society ‘accepts’ and technology ‘enables’ some sort of course correction. Instead what the science community finds is that unless the political discussion happens throughout, or even if it does, the data will seldom ‘speak for itself’. In fact, much of the data has been called into question by all sorts of communities, professional and societal. The fact that scientists must form consensus on issues such as global climate change brings pause to the non-scientific. To some, consensus means not all scientists, and it also means not proven. To those connected with science, consensus has always been a part of how facts are established.
In fact, Howe points out how this relationship within the science industry, and between science and the community at large, is a long held tension that has always existed. He argues that science as a community should accept a need for contextual social influence and communication to help ‘sell’ findings. Limiting findings to just the ‘facts’ of research data is not likely to get the sort of outcomes science advocates hope for. The controversies created by the case of the Keeling curve and climate change is a good example of how science and society as a whole need to find ways to co-produce information from the facts of data. Howe notes that in some ways the science community has come to learn this lesson, yet stumbles still happen. One need only look at recent controversies over COVID-19, shutdowns, masks, and vaccines to see how the tension still exists.
