Some ecologists start their careers planning to study climate change, and others make a decision to pivot towards that line of research. But something I find fascinating is that there are ecologists, myself included, who didn’t necessarily set out to study climate change, but who are accidental climate change biologists. To give just one example: if you work on a time series on natural populations, communities, or ecosystems that extends more than a few years, chances are you’ve found that climate change is now a part of what you’re studying.
I’ve thought about this over the years as projects we work on that started out as basic research into host-parasite interactions end up relating to climate change. Some links are obvious—wanting to understand how temperature influences host-parasite interactions leads pretty naturally to thinking about how climate change will influence host-parasite interactions. Some links are less obvious—for example, we wondered whether the light environment might be influencing when and where we saw parasite outbreaks. As I recall, our initial interest in this was not related to climate change. But lakes are getting browner, in part due climate change, so any work we do on how lake light levels influence disease naturally links with climate change. And we now have some data on host-parasite interactions in lakes that spans 1-2 decades. Once you’re into decadal time scales, you have to consider the impact of climate change on what you’re seeing.
I’ve also thought about this in terms of some projects I didn’t work on. When I started grad school, one of the projects I was thinking of working on related to what was going on under the ice in lakes in winter, and how things like snow cover influenced that. So, when I saw news articles about a new study showing that there will be an “extensive loss of lake ice…within the next generation”, I thought back to those grad school plans to work on lake ice & snow cover. My recollection is that my interest in that project was mainly wanting to understand the basic biology of lakes, but clearly it would have ended up being a study of climate change if I’d pursued it.
Based on conversations with colleagues, I know I’m not alone in coming to realize that I am an accidental climate change biologist.
So, I’m curious: for my fellow accidental climate change scientists, when did you realize you were studying climate change?
