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

Gases that deplete the ozone layer may beresponsible for the effects of climate change observed in the Arctic from 1955 to 2005. Such a disappointing conclusion was made by scientists studying the impact of climate change in the region. The main mystery all this time was that the Arctic was somehow heated more than 2 times faster than the rest of the globe, losing ice at an incredible speed. What is the reason for this phenomenon and can we prevent the loss of ice in the Arctic region?

The Arctic warms up 2 times faster than the rest of the planet

Why is the Arctic melting?

The most massive climate changecurrently occurring in the Arctic region, may be associated with ozone-depleting substances. According to an article published on, chlorofluorocarbons (CFCs) heat the planet’s atmosphere several thousand times more efficiently than carbon dioxide. Most studies of these chemicals have focused on studying their effects on the protective ozone layer of the Earth, especially on the Antarctic ozone hole discovered in 1985 in the southern hemisphere of the planet. Mark England, a climatologist at the Scripps Oceanography Institute in California, believes that analysis of modern climate models without CFCs proves an increase in the Earth’s average temperature of 0.82 degrees since 1950.

However, given the presence of ozone-depletingthe number of compounds obtained as a result of simple calculations unexpectedly jumps to 1.59 ° C. Using models with fixed concentrations of CFCs and varying the thickness of the ozone layer, a team of researchers was able to explain the warming directly by chemicals, rather than the changes caused by them in the ozone layer.

Melting ice in the Arctic could be disastrous for local flora and fauna.

Global CFC concentration started graduallydecline after the adoption of the Montreal Protocol in 1989, which called on the world's population to phase out the use of these substances. Despite the fact that this factor has a positive effect on the climatic conditions of the Arctic, experts from the University of Washington note that it is too early to talk about the full-fledged possibility of preserving ice. So, the average annual temperature of this area has already grown by about 6-7 degrees over the past few years. Scientists hope that further reduction of harmful emissions into the planet’s atmosphere will entail at least a partial mitigation of the region’s climatic changes, as ozone-depleting substances continue to leave the atmosphere.
