    • Bruk og misbruk av klimaframskrivninger 

      Sorteberg, Asgeir (CICERO Senter for klimaforskning, 2009)
      Forskere er avhengig av pålitelige klimaframskrivninger for å kunne si hvilke konsekvenser klimaforandringer får for mennesker og samfunn i framtiden. Men hva kan klimaframskrivninger brukes til og hvordan bør ...

    • Calving rates at tidewater glaciers vary strongly with ocean temperature 

      Luckman, Adrian; Benn, Doug; Cottier, Finlo; Bevan, Suzanne; Nilsen, Frank; Inall, Mark (Nature Publishing Group, 2015-10-09)
      Rates of ice mass loss at the calving margins of tidewater glaciers (frontal ablation rates) are a key uncertainty in sea level rise projections. Measurements are difficult because mass lost is replaced by ice flow at ...
