Dr. Kerry Emanuel’s talk on Revolutions in Climate Science showcased the many individuals whose efforts contributed to the development of the field. His collection of little revolutions made me question the limitations of the word ‘revolution.’ If the field of climate science came about due to multiple simultaneous revolutions, can one concrete set of revolutionary criteria explain all of the changes in the field?

Emanuel traced the roots of modern climate science back into the 19th century through multiple other fields. Advancements in fields including geology, physics, and chemistry all contributed to the development of climate science. Taking out any of those important contributions would render the future of climate science in a different way, but can each moment be counted as revolutionary? Is it possible to pinpoint one discovery or contribution as THE revolutionary moment, the spark of the revolution?

Perhaps a revolution is best considered on a large timescale, something like 300 plus years. Viewing the development of climate science as one continuous revolution means that it is in a constant revolutionary state. How does one pinpoint the exact moment of revolution? After all, each discovery is built on the thoughts, ideas, and coincidences that came before, building up a sequence of knowledge.

According to theorist Thomas Kuhn, paradigm shifts occur in scientific theory after a critical mass of new data or ideas constitute enough evidence to overturn the previously held beliefs. Under this conception of science, the development of any field is a series of revolutionary changes. If we apply this mode of thinking to climate science, what are the paradigm shifts? It is difficult to identify them from the overview that Dr. Emanuel gave, although he undoubtedly would be able to identify them.

In contrast to the increasing specialization of many fields, it seems that climate science is continually dependent on information from many different disciplines. In order to account for all of revolutionary moments in climate science, one would have to document all of the small moments in all of the fields that lead to the intellectual growth of the scientists and the public growth of perception surrounding the information.

Dr. Emanuel really made me think about all of the small moments that went into the lives of all of the scientists who collectively developed the field. Perhaps pinpointing a revolution is beside the point. A revolution does not need to have a distinct beginning or end. The climate scientists of today have a vast history to look back on, a long, revolutionary history, which gives legitimacy to their field in the face of the doubts that some have against their work.   It truly is a continuous revolution. Who knows what the next phase of the revolution will hold?
