Solar forcing as an important trigger for West Greenland sea-ice variability over the last millennium

Tallbloke's Talkshop

H/T to Andrew for alerting me to this new paper published in Quaternary Science Reviews.

From the paper:

14C-greenland-sea-ice Fig. 5. Reconstructed sea-ice concentrations from core GA306-GC4 compared to the 14C production rate corrected for the fossil fuel (Suess) effect for the period from 1850 to 1950 AD (Muscheler et al., 2007). (a) The direct comparison of sea-ice concentration (blue) and 14C production rate (red), as well as with DTSI (orange; difference of total solar irradiance from 1365.57 W/m2 ) (Steinhilber et al., 2012)

To investigate the feedback processes linking solar activity and sea-ice cover, we used the coupled climate model COSMOS, which indicates that a decrease in solar radiation results in increased sea-ice cover (Fig. 7a) and decreased sea-surface temperature (Fig. 7b). A strong negative correlation between sea-ice variability and solar forcing is observed along the eastern and southwestern coast of Greenland and in the Arctic Ocean, indicating that in this…
