The Arctic is melting 2 times faster than expected. What is the reason?

the Arctic is warming 2 times faster than all other parts of the planet
The Gases that Deplete the ozone layer, may be responsible for the consequences of climate change observed in the Arctic from 1955 to 2005. With such a disappointing conclusion was made by scientists studying the impact of climate change in the region. The main mystery of the whole time was the fact that the Arctic is somehow heated by more than 2 times faster compared to the rest of the globe, losing ice at an incredible rate. From what is related to this phenomenon and whether we can prevent the loss of ice in the Arctic region?
Why the Arctic is melting?
The Most ambitious climate change currently occurring in the Arctic region, may be associated with ozone-depleting substances. According to an article published on the portal , chlorofluorocarbons (CFCs) heated the planet's atmosphere several thousand times more effective than carbon dioxide. Most studies of these chemicals was focused on the study of their effects on the protective ozone layer of the Earth, particularly the Antarctic ozone hole, discovered in 1985 in the southern hemisphere of the planet. Mark England, a climate scientist from SCRIPPS institution of Oceanography in California, believes that the analysis of modern climate models, excluding CFC proves the increase in the average temperature of the Earth by 0.82 degrees since 1950.
However, given the presence of ozone-depleting compounds, obtained as a result of simple calculations, the number suddenly jumps to 1.59 °C. Using a model with fixed concentrations of CFCs and by varying the thickness of the ozone layer, a team of researchers were able to explain directly to the chemicals and not changes caused by them in the ozone layer.
Melting ice in the Arctic could have disastrous consequences for the local flora and fauna.
Global concentrations of CFCs started to decrease gradually after the adoption into force of the Montreal Protocol in 1989, which encouraged the world population to gradually abandon the use of these substances. Despite the fact that this factor has a positive influence on the Arctic experts from the University of Washington noted that talking about the full preservation of ice is too early to say. So, the average temperature of this area has grown by approximately 6-7 degrees over the last few years. Scientists hope that the further reduction of harmful emissions into the atmosphere of the planet would entail at least a partial mitigation of climate change in the region as ozone depleting substances continue to leave the atmosphere.
