English: Projected temperature increases in the Arctic due to climate change, 2090 (NCAR-CCM3, SRES A2 experiment).
Climate change, due to increased concentrations of greenhouse gases in the atmosphere, has lead to increased temperatures and large scale changes in the Arctic. The Arctic sea ice is decreasing, permafrost thawing and the glaciers and ice sheets are shrinking. The projected climate situation in 2090 are presented in this figure, the temperatures are annual values from the NCAR-CCM3 model, ensemble averages 1-5 for the SRES A2 experiment. The ice and permafrost are from the ACIA (Arctic Climate Impact Assessment).
Deutsch: Projizierter Temperaturanstieg in der Arktis aufgrund des Klimawandels, 2090 (NCAR-CCM3, SRES A2 Experiment).
Der Klimawandel, der auf eine erhöhte Konzentration von Treibhausgasen in der Atmosphäre zurückzuführen ist, hat zu einem Anstieg der Temperaturen und zu weitreichenden Veränderungen in der Arktis geführt. Das arktische Meereis nimmt ab, die Permafrostböden tauen auf und die Gletscher und Eisschilde schrumpfen. Die projizierte Klimasituation im Jahr 2090 ist in dieser Abbildung dargestellt, die Temperaturen sind Jahreswerte aus dem NCAR-CCM3-Modell, Ensemble-Mittelwerte 1-5 für das SRES A2-Experiment. Das Eis und die Permafrostböden stammen aus dem ACIA (Klimafolgenabschätzung für die Arktis).
