چکیده
Abstract In recent decades, the warming in Arctic has been much faster than rest of world, a phenomenon known as amplification. Numerous studies report that is either twice, more or even three times fast globe on average. Here we show, by using several observational datasets which cover region, during last 43 years nearly four globe, higher ratio generally reported literature. We compared observed amplification with simulated state-of-the-art climate models, and found four-fold over 1979–2021 an extremely rare occasion model simulations. The ratios are consistent each other if calculated longer period; however comparison obscured uncertainties before 1979. Our results indicate unlikely event, models systematically tend to underestimate

Warming of the arctic ice-ocean system is faster than the global average since the 1960s
[1] Model results and observations both indicate warming of the world ocean from 1955 to 2003. Forced by reanalysis data, the model also shows that the warming of the arctic ice–ocean system is faster than the global average since the 1960s; there is a small but widespread increase in heat content of the Arctic Ocean’s waters and a larger increase of latent heat embodied in the ocean’s decreasi...

متن کاملArctic sea ice decline: Faster than forecast
[1] From 1953 to 2006, Arctic sea ice extent at the end of the melt season in September has declined sharply. All models participating in the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4) show declining Arctic ice cover over this period. However, depending on the time window for analysis, none or very few individual model simulations show trends comparable to obs...
