Warning: the Arctic ocean will be ice-free before 2050

A study revealed that the sea around the Arctic will be ice-free in the summer before 2050, even if emission-reduction goals are achieved, as a model has been set for the effect of different levels of carbon dioxide emissions on sea ice in the Arctic, and a team of researchers found that the goals of The Paris climate agreement will not be enough.

According to the British newspaper “Daily Mail”, it usually grows Sea ice in the Arctic It shrinks according to seasons, but for the time being some ice, which is home to animals like polar bears, always remains.

But the team responsible for the results said that we can still control how many times the Arctic melts and how long they will last in the future, as climate modeling scientist Dirk Notz from the University of Hamburg in Germany and his colleagues conducted the study.

“If we reduce global emissions rapidly and dramatically, and thus keep global warming to less than two degrees Celsius in relation to pre-industrial levels, sea ice in the Arctic will disappear from time to time in the summer until before 2050,” Dr. Nuts said. It really surprised us. ”

The Arctic is now covered in sea ice throughout the year, but every summer the sea area covered by ice decreases before it grows again in the winter.

Also, due to the greenhouse effect of greenhouse gases such as carbon dioxide and methane, the areas of the Arctic Ocean that were covered in ice constantly began to melt during the summer months.

If humankind succeeds in rapidly reducing its emission levels in the future, it is expected that years will be completely ice-free in the Arctic only from time to time, but with higher emissions, the Arctic Ocean will become ice-free in the summer of most years.

Additional melting will not only contribute to sea level rise, but will also mean the loss of valuable fishing grounds and polar bears’ habitats.

In their study, researchers used the latest climate models to predict the effects of different carbon dioxide levels on the state of sea ice in the Arctic.

These are the same models used by the Intergovernmental Panel on Climate Change, the United Nations Environmental Research Branch, and the full results of the study were published in the journal Geophysical Research Letters.
