Norwegian scientists from the University of Tromsø have concluded that the melting of Arctic sea ice could lead to sharp cooling in Northern Europe. The research was published in the scientific journal magazine Nature Communications (NatComms).
The conclusions of experts are based on the study of the last interglacial period. Initially, about 100 thousand years ago, global temperatures were higher than today, ice volumes were lower, and sea levels were much higher.
The Nordic Seas between Greenland and Norway serve as a key area for ocean heat transfer, influencing weather patterns far beyond their geographic boundaries.
Modeling showed that melting sea ice in the Arctic changes the salinity and density of water, disrupts the normal flow of currents and affects the circulation and distribution of warm masses.
The researchers used a combination of biological, inorganic and organic geochemical tracers from sediment cores at the bottom of the northern seas. By analyzing traces in these sediments, the team was able to reconstruct past temperatures and salinity levels.
Scientists have stated that by 2050 the Arctic may turn into an interglacial state, which could affect the climate in Northern Europe.
