Although a report about Arctic climate change was filed by the U.S. government in 1922, a later addition seemed to predict rising sea levels and the flooding of cities. This addition has nothing to do with the original report.
Also, great short video about endangered polar bears. We will continue to lose sea ice over the next few decades even if air temperature trends are halted or reversed. Polar bears will either starve because they are stranded too far from sturdy ice, or if they cannot reach ice fields. The third possibility we are now seeing is that polar bears will take to land again, hunting and scavenging in human occupied terrain.
