The latest report released by the National Oceanic and Atmospheric Administration (NOAA) affirms that as a result of the colossal loss of sea ice, autumn air temperature in the Arctic is a record 5º C (9°F) above normal, since the warming trend began in the mid-20th century.
As temperatures continue to rise due to human generated carbon dioxide emissions, white snow and ice give way to darker water and land beneath them. These darker surfaces absorb more heat than what would be reflected by the lighter snow and ice. This results in a positive feedback loop, causing more snow and sea ice to melt, exacerbating the Arctic warming.
