Winter
Temperatures Rise, Unleashing Viruses Over Ice-Free Arctic
Fears
of the global warming have been refueled by the recent report from
the Arctic Council, which predicted winter temperatures to rise by a
solid four degrees over the next 30 years. This warming is predicted
to affect animals and humans alike, unleashing viruses upon the
Arctic flora and fauna

Nowhere
else on the globe have temperatures been rising as fast
as in the Arctic, and this trend is expected to continue
in the future. The recent report by the Arctic Council
predicted the warming to have a devastating effect on the
number of areas. Over the past 50 years, the temperature
in the Arctic regions has risen more than twice as fast
as the world median. Over the next 30 years, autumn and winter
temperatures can rise by an additional 4 degrees.
"It
will have serious consequences," Peter Sköld, the head of the
Arctic Center at Umeå University, told Swedish national
broadcaster SVT,
venturing that the rise will happen sooner than man thought
before.
One
of the foremost consequences of the Arctic warming will be
the melting of the polar ice and the rapid rise of global
sea levels. The Arctic Ocean could become free of sea ice in the
summer as early as 2030 or even before that. This is
expected to put extra strain on polar bears, walruses and
other animals that rely on ice for survival. Additionally,
thawing permafrost that holds 50 percent of the world's carbon
is already affecting northern infrastructure and could release
significant amounts of methane into the atmosphere.
Among
other things, viruses will be spread further north and bacteria
present in the soil will be released. Finally, the risk
of forest fires is also expected to increase.
"We
already notice diseases that we have not known before," Peter
Sköld said, citing ticks that are being encountered increasingly
farther north together with hare pest, vole fever and the like.
The
warming will also affect fish stock, introducing unforeseen
consequences in Arctic waters. According to Sköld, Arctic
char population alone is expected to drop by 73 percent.
Additionally, new species can migrate further north as the
Arctic waters get progressively warmer. The arrival of a more
aggressive species could spell doom for the Arctic fauna. Also,
the climate will be difficult to predict. Late April
temperatures in northern Europe may thus fluctuate between 30
degrees' heat and heavy snow.
"We
will have severe temperature fluctuations. It can freeze and thaw
every second. This would put reindeer on the verge
of starvation," Peter Sköld said.
On
the global scale, the Arctic warming could alter the Southeast Asian
monsoon, possibly leading to up to 70 percent less rain
in India and Southeast Asia during the summer monsoon
season. According to Skiöld, the only reliable way of reversing
or postponing the warming is to reduce emissions and change our
lifestyle, which has a direct impact on the climate.
The report called
"Snow, Water, Ice and Permafrost. Summary for Policy
Makers" was produced by AMAP, a group working within the
framework of the Arctic Council and featuring contributors
from all the eight member states. Over 90 scientists
collaborated on the report.
