This paper looks at trends (from 1984-2018) in sites across Alaska's Arctic parks. The author found that 2005-2007 experienced a major episode of lake drainages, following very warm years (2003-2004). This was exceeded, however, by a recent lake drainage event that started in the summer of 2018 after another series of record-warm years since 2014. To put it in perspective, from 2000-2017, the average rate of water loss was about 700 hectares (1,730 acres) per decade; 760 hectares (1,878 acres) of lake surface disappeared in 2018 alone. One reason we are concerned about this is that larger lakes in the Arctic are important habitat for Yellow-billed and Pacific Loons. The Yellow-billed Loon is a rare species in North America, so any additional habitat loss could impact their numbers. In addition, the loss of lakes will shift those ecosystems into meadows and shrubland, creating further ecological changes.
