When I go for a walk in the woods here today – through a forest of white pine, hemlock, and birch, dotted with lakes and lush bogs – it’s hard to imagine that climate change will bring drastic alteration to this landscape within my lifetime. However, a piece of research that came out this past summer hopes to help us with our lack of imagination by finding contemporary analogues for Wisconsin’s climatic future. The paper, from a UW-Madison team led by Samuel Veloz and Jack Williams, is titled “Identifying climatic analogues for Wisconsin under 21st-century climate-change scenarios,” and you can read the abstract here.
Essentially, what they did was take what climate change models say will happen to Wisconsin’s temperature and precipitation in the next fifty to one hundred years and determine what locations in the U.S. have climates most like that right now. By the mid-21st century, northern Wisconsin, where I live, should be similar to how Milwaukee is now. That may not sound like a huge shift, but if you’ve ever driven from here on the Michigan border down the length of the state, you know that a pretty dramatic change occurs when you leave the North Woods. Here we’re on the edge of the great boreal forest ecosystem of the north, but down there it’s much more typical pastoral Midwestern scenery – the land of the dairy farms that give Wisconsin its reputation for cheese.
These analogues are useful in several ways. For one thing, they make the idea of climate change seem much more concrete; just reading statistics about projected changes in temperature and precipitation doesn’t necessarily help non-scientists get a mental picture of what’s coming. The authors of the research also point out that this could be useful to farmers, city planners, etc. in trying to anticipate and prepare for future changes. The coolest bit is that they created an online tool that you can use to play with these models yourself to figure out where your particular patch of Wisconsin is headed (yes, only Wisconsin, sorry) – check it out at How Is Wisconsin’s Climate Changing?
Even though this sort of thing makes me sad, it’s also fascinating. What do you think, fellow North Woods folks?
