We note that this study has not taken into account the potential changes in atmospheric humidity caused by sea ice removal, which should be a focus of future work.

«The chemical removal of CO2 in sea ice occurs in two phases.
This is particularly concerning for the West Antarctic Ice Sheet, which is largely grounded below sea level [9], and removal of this could raise sea levels by 3.3 m [10, 11].
In each case, the removal of ice around the periphery seems to allow inland ice to move more readily toward the sea.
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.
With respect to how the atmosphere responds to the removal of summer sea ice, I looked at this in the paper
Here the land is sinking as the continent adjusts to the removal of massive ice sheets, but it appears the sea is rising.
Due to the long - timescales associated with the carbon cycle (e.g., Solomon et al., 2009), reversing sea ice loss would in practice require some type of active carbon removal from the atmosphere.
Given the rather diffuse ice cover in the Beaufort and Chukchi seas (Figure 5) combined with a return to favorable atmospheric conditions for ice removal, ice loss thus far in August has been faster than the 1979 - 2000 climatology.
These results suggest that the tropospheric oxidizing capacity could change dramatically over the Arctic if summer sea ice is to retreat in the future, something that could impact the removal of important gases (methane, carbon monoxide) in this region.
These runs are examined for evidence of accelerated climate change associated with the removal of sea ice, particularly due to increasing surface albedo feedback.
