Alaska was purchased from Russia in 1867 but only became a state in 1959, just months before Hawaii. It’s awe-inspiring and rugged terrain stretches over 570,000 miles and is inhabited by 731,000 people making it the largest state in the US by land mass and 49th by population. Almost one third of the state sits in the Arctic Circle and 4.5% of it is covered by 100,000 glaciers covering 29,000 square miles. The state has more coastline than the rest of the country combined and its two largest forests. Wildlife in this last frontier is diverse and abundant.
Alaska has warmed twice as fast as the rest of the country and with that warming, its permafrost has begun to melt. Permafrost is ground with a temperature that remains at or below freezing, and it provides a stable foundation for much of Alaska’s infrastructure— found beneath 85% of the state. As permafrost melts, the ground sags and infrastructure like roads and buildings deteriorate or collapse. Also a carbon store house, permafrost poses a global threat when it melts, beyond the immediate costs to Alaskan communities and dangers to both humans and wildlife. As frozen plants and animals in the permafrost warm and decompose, greenhouse gases are released into the atmosphere. The amount of carbon now released by the world’s permafrost is nearly equal to the emissions of all of Japan.
Alaska’s Native communities will most directly bare the brunt of these changes. 87% of these communities are experiencing erosion and some are facing relocation. Many of the most remote communities rely on subsistence farming and are faced with threatened food supplies. In a rapidly-warming Alaska, wildlife also faces devastating consequences. For example, multiple mass bird die-offs have occurred since 2014, as warming seas have disrupted ecosystems and broken the food change on which they depend to survive.
Most of Alaska’s electricity currently comes from natural gas. Since assuming the presidency, President Trump has been eager to open more of Alaska to oil companies for drilling. Despite impediments from coronavirus to participation in the public comment period, the administration has moved ahead with a ConocoPhillips’ Willow project in the National Petroleum Reserve-Alaska. However, a growing list of banks have publicly stated that they will refuse to finance drilling projects in the arctic. While renewables currently contribute to a very small percentage
Alaska’s energy use, the state has a nonbinding commitment to generate 50% of its energy from renewables by 2050. In May of 2020, the state government enacted a bill to integrate electrical utilities, increasing energy efficiency and paving a path for the transition to renewables. Anchorage, the state’s largest city, enacted a Climate Action Plan in May of 2019 which focuses on reducing greenhouse gas emissions while preparing for the impacts of climate change.
