MOSCOW, 22 APR – RIA Novosti. Periods when the Arctic ocean in summer will be completely ice-free, there will be up to 2050 under any rate of reduction of CO2 emissions, said the report from the University of Hamburg devoted to the study of melting Arctic ice.
the Warming of the Earth’s surface is most strongly noticeable in the Northern latitudes, the rate of change of temperature there is twice higher than the global average. One of the main consequences of climate change in the Arctic will be the release of ice the Northern sea route. Countries are trying to “slow down” the warming, reducing CO2 emissions – a greenhouse gas that accelerates climate change.
“in the Summer Arctic ocean will likely be completely ice-free before 2050. Even if temporarily, but such a phenomenon will be observed. The effectiveness of the conservation measures of the climate may affect the long-term ice-free periods”, – is spoken in the message.
As explained in the press release, the research team analyzed the calculations of 40 different climate models. The scientists examined the evolution of sea ice cover in the scenario with high CO2 emissions and low climate. As expected, in this scenario, the ice quickly disappeared in the summer.
But a new study has shown that sea ice in the Arctic will also sometimes disappear, and in the case of rapid CO2 emissions reduction.
“Unless we quickly and significantly reduce global emissions, and thereby stop global warming to below 2 degrees relative to pre-industrial levels, even under this condition, Arctic sea ice is likely to be periodically disappear during the summer even until 2050. It really surprised us,” – are reported words of the head of research Dirk Natca from the University of Hamburg.
