A Village Falls into the Sea

In the middle of the map, climate change can feel like an abstraction. Is a warmer, wetter summer an anomaly in the weather pattern, or part of a greater change? Is this an early heat wave just a seasonal spike?

At the edges of the map though, the impact is very real. Solid ground is literally disappearing. At Sierra, Rachel Rivera visits Shishmaref, an island village north of Nome, Alaska, and witnesses the effect that global warming — and the resulting rising sea level — has had on this remote Native Alaskan settlement.

Long accustomed to living under the most extreme weather conditions, Inupiaq communities on Alaska’s Arctic coast are facing their toughest challenge yet. The Arctic is warming twice as fast as the rest of the planet. Average air temperatures are more than 6°F warmer than they were at the beginning of the 20th century, and the lack of reflective snow is causing both land and sea to absorb more solar heat. The sea ice, critical to the creatures that sustain human life here, is melting. Sea ice also serves as a natural buffer, shielding coastal communities from the direct impact of storms. Recently, Shishmaref has been subject to stronger storm surges and increased flooding. A storm in 2013 eroded 50 feet of the beach overnight—including part of the road next to the airstrip, the only way out if the village should have to evacuate.
