Scientists can't tell how fast the ice is melting in the Arctic

16 march 2023
Norwegian and American researchers compared the calculations of 14 popular climate models of the Arctic Ocean from 1970 to 2017 with the results of real observations and found errors – this concerns forecasts, the structure of ocean layers, the movement of deep currents.
Scientists admitted that they cannot now give an accurate estimate of how fast sea ice is melting in the Arctic. According to scientists, climate models of the Arctic Ocean underestimate the effects of global warming, according to an article in the Journal of Climate.
In recent years, average temperatures in the Arctic and Antarctic have increased by 6-7 degrees. Scientists suggest that further melting of ice can lead to serious changes in currents and climate on the whole planet.
Earlier it became known that due to forest fires, a record amount of CO2 got into the atmosphere, and the World Ocean absorbed a record amount of heat in 2022.
Russian scientists have hypothesized that the Arctic could have warmed up due to strong earthquakes, ttelegraf.ru writes.
