Most of the studies on the Arctic climate and ice trends cited to support the proposed listing assumed that the buildup of heat - trapping gases was probably contributing to the loss of sea ice, or that the continued buildup of these gases, left unchecked, could create ice - free Arctic summers later this century, and possibly in as little as three decades.

(08/31/2009) If current melting trends continue, the Arctic Ocean is likely to be free of summer sea ice by 2015, according to research presented at a conference organized by the National Space Institute at Technical University of Denmark, the Danish Meteorological Institute and the Greenland Climate Center.

Results show that the globally and annually averaged radiative forcing caused by the observed loss of sea ice in the Arctic between 1979 and 2007 is approximately 0.1 W m − 2; a complete removal of Arctic sea ice results in a forcing of about 0.7 W m − 2, while a more realistic ice - free - summer scenario (no ice for one month, decreased ice at all other times of the year) results in a forcing of about 0.3 W m − 2, similar to present - day anthropogenic forcing caused by halocarbons.
