Climate Change at the Arctic's Edge

Northern ecosystems are being transformed by climate change. Join this long-term monitoring effort to explore what these changes mean for the Arctic—and the rest of the world.

Churchill is a small town perched on the seacoast within the Hudson Bay Lowlands, North America’s largest wetland. The area’s most famous inhabitants are its 57,000 beluga whales and 1,000 polar bears; Churchill advertises itself as both the beluga whale and the polar bear capital of the world. However, global climate change is threatening this landscape and the wildlife that resides there. Churchill has warmed approximately two degrees Celsius since record-keeping began in the 1880s, resulting in a myriad of ecological changes, such as shrinking polar sea ice, retreating glaciers, and less snowpack that melts earlier, putting Churchill on the front line of climate change.

You’ll measure evidence of global warming near Churchill and help researchers as they learn all they can about this fragile environment. If you join one of the summer or fall teams, you may don waist-high waders to take water samples and assess the abundance of the fish and frogs that make these northern wetlands their home. You’ll also help measure permafrost and monitor the health of the tree line by examining tree cores, which allow researchers to reconstruct tree life histories (to date, the oldest living tree this team has found dates from 1643).

But to truly experience the power of the North, join a winter team that focuses on assessing snowpack and taking snow samples. You’ll travel between research sites on a sled pulled by a snowmobile and may even get the chance to build an igloo.
