HIGHLIGHTS
- who: Urs Siegenthaler and collaborators from the University of Bern, Bern, Switzerland have published the paper: Supporting evidence from the EPICA Dronning Maud Land ice core for atmospheric CO2 changes during the past millennium, in the Journal: (JOURNAL)
- what: The results of the model show that the effect of diffusion through the ice matrix may influence the concentration in the normal bubbles by several ppmv.
SUMMARY
A record from Central Greenland (Barnola et_al, 1995) shows CO2 concentrations of 283.0 ± 2.4 ppmv for the period AD 1600-1800 and 289 . . .
