A Day in the Life of a Garbage Scientist

As I stood, gazing intently down near my feet, I felt the water flow past my knees. Even with my waders on, I could feel its cool relief in the summer sun. As I looked into the water, I caught a glimpse of a dark, circular shape under the muddy stream bed. I reached down to grab it, and as I pulled, I realized that it was not going to budge. What I thought was a lone bike tire was actually still attached to an entire bike, buried under the muck. I called my teammate, undergraduate researcher Sam Fredrickson, over and we traced the pattern of the metal crossbars and found a place to grip. With our combined effort, we pulled the frame free from under the layers of mud that had accumulated over it.

Why Do We Get Cold Weather When the Climate Should be Warming?

While it’s widely understood that our planet’s climate is warming, there is a lot of confusion about how this influences our weather from year to year. If you kept up with the news at all between June and November of 2017 and 2018 (the time frame that defines the Atlantic hurricane season), you may remember seeing one headline after another with updates on the latest major storm to wreak havoc on the coastal communities of the southeast and Puerto Rico. Perhaps you even saw some heated discussions about whether or not these storms had proven the existence of climate change (click here for the latest evidence). With the cold snaps in the winter of 2018 and the polar vortex of 2019, though, many have publicly questioned why cold weather doesn’t disprove climate change. Despite the confusion in the media, the scientific consensus is clear – the global climate is warming, and the cold weather is part of it.

Will Global Warming Stop the Snow?

I bet you’ve heard it before, maybe in the news, from your uncle, or maybe from a skeptical friend. How can climate change be happening if we are getting so much snow? The reasoning seems sensible – as temperatures go up, the amount of snow should go down, kind of like a seesaw. After all, we don’t have snow in summer because it is too warm – precipitation falls as rain. But we are experiencing climate change, temperatures are going up, and in the Great Lakes we are getting more snow. How can that be possible? Continue reading “Will Global Warming Stop the Snow?”
