Marine heat waves are predicted in the Arctic

Scientists from the University of Hamburg predict that in the near future heat waves will become a common phenomenon in the Arctic and are the result of high levels of anthropogenic greenhouse gas emissions. The research was published in the journal Communications Earth & Environment.

The authors found that conditions in the Arctic have changed dramatically since 2007. Between 2007 and 2021, there were 11 marine heat waves in the marginal zones of the Arctic Ocean, which resulted in an average temperature increase of 2.2 degrees Celsius above the seasonal norm and lasted an average of 37 days. Since 2015, marine heat waves have been observed in the Arctic every year
