Scientists Told About Changes In The Ice Melting Regime In The Arctic
Periods, when the Arctic ocean will be completely freed from ice in the summer, will be observed until 2050 at any rate of reducing CO2 emissions, according to a report from the University of Hamburg, dedicated to the study of melting Arctic ice.
The warming of the Earth's surface is most noticeable in the Northern latitudes, the rate of temperature change there is twice as high as the average for the planet. One of the main consequences of climate change in the Arctic will be the release of ice from the Northern sea route. Countries are trying to "slow down" warming by reducing emissions of CO2, a greenhouse gas that accelerates climate change.
"In summer, the Arctic ocean is likely to be completely free of ice until 2050. Even temporarily, this phenomenon will be observed. The effectiveness of climate conservation measures may affect the long-term duration of ice-free periods," the report says.
As explained in the press release, the research team analyzed calculations of 40 different climate models. Scientists looked at the evolution of the Arctic sea ice cover in a scenario with high CO2 emissions and little climate protection. As expected, in this scenario, the ice quickly disappeared in the summer.
However, a new study has shown that sea ice in the Arctic will also sometimes disappear if CO2 emissions are rapidly reduced.
"If we quickly and significantly reduce global emissions and thereby stop global warming at below 2 degrees relative to pre-industrial levels, even with this condition, the Arctic sea ice is likely to periodically disappear in the summer even before 2050. This surprised us," the report quoted research Director Dirk Father from the University of Hamburg as saying.
