Permafrost Melt in Northern Alaska

In this aerial image, thermokarst lakes are seen on June 21, 2017 in Alaska, United States.
This image shows thermokarst features, or disturbances created by melting and subsiding permafrost in Alaska on June 21, 2017. The water features from melting soil ice on the landscape are becoming larger and more common. Alaska is one of the fastest warming places in the world as a result of global climate change-- on average, Alaska is warming 1.5x faster than the rest of the United States, with most of that warming happening in the winter and in the spring. Alaska's low population density and remoteness shelter it from widespread news coverage about the impacts of climate change. Images such as these, especially as a series, help us visualize how quickly and to what extent landscapes are changing.
