Även om de inre delarna av Östra Antarktis istäcke växer så minskar landisen totalt sett med en allt snabbare takt. Antarktiska havsisen växer trots en kraftig uppvärmning av den Antarktiska oceanen.
Istäcket på Antarktis växer
"Mängden is som omger Antarktis är nu på de högsta nivåerna sedan satelliterna började mäta dem för nästan 30 år sedan. Det är helt enkelt för kallt för att regna på Antarktis och det kommer fortsätta på samma sätt under en lång tid. Det finns kort och gott mer is än någonsin kring Antarktis." (Patrick Michaels).
Det är viktigt att skilja på den Antarktiska landisen och havsisen, vilka är två separate fenomen. Rapporter om Antarktis is missar ofta att skilja på land- och havsisen. För att sammanfatta situationen med Antarktis istrender:
· Antarktis landis minskar med en allt accelererande takt.
· Antarktis sjöis växer trots uppvärmningen av den Antarktiska oceanen.
Antarktiska landisen minskar
Att mäta förändringar I Antarktis landismassa har varit en svår process p.g.a. istäckets massiva storlek och komplexitet. Emellertid har
Measuring changes in Antarctic land ice mass has been a difficult process due to the ice sheet's massive size and complexity. However, since 2002 the Gravity Recovery and Climate Experiment (GRACE) satellites have been able to comprehensively survey the entire ice sheet. The satellites measure changes in gravity to determine mass variations of the entire Antarctic ice sheet. Initial observations found that that most of Antarctic mass loss comes from Western Antarctica (Velicogna 2007). Meanwhile, from 2002 to 2005, East Antarctica was in approximate mass balance. The ice gained in the interior is roughly balanced by the ice loss at the edges. This is illustrated in Figure 1 which contrasts the ice mass changes in West Antarctica (red) compared to East Antarctica (green):
