| Summary: | Stenni et al.’s calculations result in two time series of relative temperature change, one for the Antarctic plateau and the other for the moisture source for East Antarctic precipitation. General circulation models and isotopic tracer studies show that this moisture source is the area between 30º and 50ºS in the Indian Ocean. A potential problem remains. The deu-terium excess proxy for SST can only tell us about the evaporation temperature of the average moisture reaching Dome C. The SST variations reported by Stenni et al. may thus merely reflect changes in the rela-tive contribution of moisture from different |
