There’s always a moment of intense isolation when Jessica Mejía gets dropped off on the Greenland ice sheet for a multi-week research stint. “You know you’re very much alone,” said Jessica, a postdoctoral researcher in glaciology at the University of Buffalo. Glaciers such as those that cover Greenland are melting due to climate change, causing sea levels to rise. That we know. But these glaciers are also moving. What we don’t know is just how these two processes – melting and movement – interact and ultimately impact how quickly sea levels will rise. Jessica joins Short Wave’s Aaron Scott to explain what it’s like to live on a glacier for a month, and what her research could mean for coastal communities all over the world.
