The Arctic has lost about a third of its ice during thepast 30
years. A record meltdown last summer shrank its sea ice down to 4.2
million square kilometers, from 7.8 million in 1980. If melting continues
at this increasing rate, scientists project that the Arctic summer
could be ice-free by 2013.
Raghida Haddad, Executive Editor of Al-Bia Wal-Tanmia magazine, was
among 14 journalists invited by the World Federation of Science Journalists
to join an international scientific expedition onboard the Canadian
research icebreaker Amundsen. She navigated for two weeks in the Arctic
Ocean to get first hand experience of global warming where it is unfolding
the fastest, and to relay this experience to readers throughout the
Arab region. Here are some of her sightings and reflections, published
in the September issue of Al-Bia Wal-Tanmia.
The
Arctic, 24 July 2008
White
night
Last night I slept in a swing. That's how it felt like on the Canadian
research icebreaker Amundsen, floating in the rough Arctic Ocean.
But there is no ice to break, just open blue water. The ship trotted
on submerged ice blocks, but there were barely traces of ice floating
in the Beaufort Sea were we navigated. Most sea ice has melted in
the Arctic, safe the "permanent" polar icecap and ice masses
adherent to Greenland, Alaska and the Northern territories, shrinking
at an unprecedented rate.
I arrived yesterday by helicopter from Banks Island, off Canada's
Northwestern coast, after a long 8-flight journey from Lebanon. On
that barren freezing island, I could imagine what life on the moon
could be like. Surprisingly, 120 natives still live there in the coastal
community of Sachs Harbor.
A young Inuit (commonly known as Eskimo) came to the air strip where
we were waiting for the helicopter to fly us to the icebreaker. I
asked him how livable it is on the island. "My people live on
fishing and hunting caribou, musk ox and snow geese that land in hundreds
of thousands," he said. Summer is very short on this 250-mile
long island, just two months. So Inuits cannot grow vegetables and
fruits. The villagers also have an annual quota to hunt 28 polar bears
which they sell for their hides, "but we have not filled our
quota in the past years. Fewer bears are showing up."
"There is so much open space and outdoor living," he added.
"I will not trade my life in the village for anything in the
world. This is where I grew up, hunting and fishing. This is home."
Home, sweet home, even on a remote moonlike island in the Arctic.
Life has changed, however, for the Inuits who have lived here for
thousands of years. They rely on freezing seawater in straits to move
about and cross to other islands for hunting. With unprecedented temperature
rise in the Arctic, sea ice starts to melt sooner in spring and surface
water starts to freeze later in autumn. Thinning ice is not favorable
for the Inuit way of life.
This is also what worries the pack of international scientists on
board the research icebreaker, who are studying climate change where
it where it is mostly claiming its toll: in the Arctic.

Voices of the deep
"Ms. Haddad, there are whales out there. Come up to the bridge."
I jumped out of my bed at the Captain's call, put on my thermal pants
and jacket and hit the bridge. A family of three whales was diving
about one kilometer away. The blowing out of air and water after each
dive was spectacular. Several species of whales navigate these Arctic
waters, though the populations of some are so much reduced that they
rarely show up nowadays.
You can't expect what one might encounter walking around the Amundsen.
On my way back, I saw two technicians working on a cylindrical tool:
a hydrophone. What's that? "Well," one explained, "it's
an instrument to detect and hear the songs of whales." Flocks
of whales dwell in the Arctic Ocean at this time of the year.
Detection and sampling instruments are descended in the water almost
every day. Two specialists on a motor boat dragged them away from
the ship. They will come back next year hunting for the instruments
and resulting data.

24 hours of daylight
We are navigating in the Beaufort Sea. Looking from the upper deck,
I found myself at the center of a blue circle. I finally believed
the Earth is round.
It is never too late to do anything in the arctic summer, with 24
hours of daylight. Last "night" I went out to watch the
midnight sun, hovering above the horizon. Four researchers on a motorboat
were inspecting buoys that define the location of immersed equipment
in the ocean. Three others were on deck, carrying water samples from
the Rosette, a huge apparatus with 24 computer-controlled cylinders
that collect water at different depths, reaching down to some 900
meters.
Cristina Romera, from Spain, guided me to some of the 12 labs on the
Amundsen. She is collecting water samples for the Instituto de Ciencias
del Mar in Barcelona, to study their contents of chlorophyll, bacteria,
viruses and other arctic micro-organisms. Some of these samples will
be stored in freezers under temperatures as low as -80?C using liquid
nitrogen.
Heike Link, a German researcher, was inside a lab with trays of starfish,
clams, worms and other creatures from the Arctic seafloor. She documents
their diversity and abundance and the role they play in the ecosystem.
I left her inspecting a dragon fish and spectacular worms inside tubes
that they build with slime and mud.
We also met Dr. Hayley Hung, a chemical engineer from Environment
Canada. She is the lead researcher of an international study to measure
persistent organic pollutants (POPs) and mercury in air around the
pan-Pacific area, using computer models to describe their movement
and assess the impact of climate change on their deposition in the
Arctic. These contaminants have been found at high levels in some
Arctic marine mammals, consumed by Northern people, where they accumulate
and stay in the body for a long time.

An acidic ocean
After surviving a violent storm yesterday, we spent all day in a sea
of mist.
Walking on the front deck, I saw Silvia Gremes-Cordero, from Argentina,
fitting one of her instruments on a pole and hauling it on the side
above the sea. She is researching air-sea interaction in the boundary
layer, within the first 10 meters in the atmosphere and the first
5 meters in the ocean.
"By studying small-scale turbulence, we can study gas transfer,"
she explained. This is especially important in calculating the ocean
intake of atmospheric carbon dioxide, the major greenhouse gas considered
to enhance global warming. "When developing climate models,"
she added, "the more you know about interactions between the
atmosphere and the ocean, the more accurate the models are."
As the sea absorbs more CO2 from the atmosphere, its acidity increases.
A new study revealed how some marine animals could be affected by
acidic sea water. Scientists from Sweden and Australia allowed sea
urchins to mate in water where the pH was lowered from normal 8.1
to a level of 7.7. This corresponds to an environment of triple acidity
expected by the end of this century.
Female sea urchins release their eggs in the water to be fertilized
by mail sperm. In this acidic sea water, however, their reproductive
rate dropped by 25 percent, as the sperm swam slower and less effectively.
Scientists still have to find out if other marine animals exhibit
a similar effect, especially commercial species such as lobsters,
crabs, mussels and fish.

The shrinking of Earth's air conditioner
The Arctic has lost about a third of its ice since satellite measurements
started 30 years ago. This amounts to some 3.8 million square kilometers,
with a present rate of about 70,000 square kilometers per year. A
record meltdown last summer fully opened the Northwest Passage to
navigation. If melting continues at this increasing rate, scientists
project that the Arctic summer could be ice-free maybe as soon as
2013.
"Over two million square kilometers of polar ice pack has disappeared
over the 5-year period 2003-2007," said Gary Stern, chief scientist
on the Amundsen. The minimum sea ice extent is seen in September.
Described as Earth's air conditioner, the Arctic helps cool the planet
with its white sun-reflecting sea ice. This ice melts in spring and
summer and refreezes in fall and winter. With the Arctic warming about
twice as fast as the rest of the globe in the last decades, the overwhelming
melting will reduce this cooling process. It will also disrupt marine
ecosystems and devastate wildlife, including polar bears and seals.
Here's a sad story about polar bears. They use ice floes as a means
of transportation to hunt seals. With ice increasingly melting, they
sometimes get stuck on an ice floe in the middle of the water and
can't jump to another that doesn't exist around. So they dive to hunt,
sometimes very far away that they get too tired trying to return to
land more than two hundred kilometers away. So they drown.

The second cold war
"Yes, the Arctic is warming now, but it will be cooling again
within three years," said my friend Andrej Rubchenya, a Russian
oceanographer and assistant professor at Saint Petersburg State University.
"There are eras of warming and eras of cooling. Natural forces
are too strong to respond to the human factor. Carbon emissions could
be a slight factor in the process of global warming. But unless a
thousand nuclear bombs are detonated, I can't imagine any human force
able to encounter the mighty powers of nature."
"Climate change is a political issue," he concluded.
In August 2007, two Russian legislators in a small submarine planted
a Russian flag on the seabed of the North Pole. That was another act
in Russia's claim to 1.2 million square kilometers, about half the
floor of the Arctic Ocean.
In response, Canada's Prime Minister Stephen Harper announced plans
to build two new military bases in the Canadian Arctic. With ice melting
faster than ever, the issue now is who will own the possible huge
mineral deposits buried under the Arctic floor. According to some
geologists, the Arctic could hold about 25 percent of the world's
undiscovered oil and natural gas.
Arctic countries that would claim rights include Russia, the United
States, Canada, Denmark and Norway. This new "gold rush"
might pave the way to a new kind of cold war.
According to the United Nations Convention on the Law of the Sea,
coastal nations can have economic sovereignty over up to 200 nautical
miles off their shores. The rest is considered international waters.
However, a nation can claim territory beyond this limit if the edge
of its continental shelf extends further. This has started, with Russia
claiming the huge Lomonosov Ridge underneath the Pole. The Danes are
trying to prove that their side of the ridge (now detached) was once
part of Greenland which belongs to Denmark. In this Endeavour, the
United States might finally ratify the UN Convention and claim the
shelf extending Northward of Alaska.
The Convention also governs navigation rights, in focus now after
the first-time recorded complete opening of the ice-blocked Northwest
Passage in summer 2007. With global warming and ice melting, it could
become a commercial navigation channel. Canada claims rights over
this passage, which snakes between islands of its northern archipelago.
Last May, Prime Minister Stephen Harper committed to augment Canadian
Forces' capacity to "protect Arctic sovereignty and security."
But other maritime countries insist that it should be open to international
traffic, as is the case in other strategic waterways like those in
the South China Sea.
Calling on the American administration to take a step, former US Coast
Guard Lt. Commander Scott Borgerson argued that "unless Washington
leads the way toward a multilateral diplomatic solution, the Arctic
could descend into armed conflict."

Beirut, Lebanon, 14 August 2008
Where has the ice gone?
Last night I dreamt I was in the Arctic again.
I am back home now, safe and sound. What an incredible experience!
It was so enriching living with scientists who are doing all kinds
of research, tackling the indicators and effects of climate change.
Summer 2007 set a meltdown record of one million square kilometers,
shrinking the Arctic sea ice down to 4.2 million square kilometers,
from 7.8 million in 1980. With global warming tightening its grip,
it is projected that this summer will break another record.
Many scientists believe that global warming is caused by human actions,
mainly burning fuels for industry, transportation, electricity and
other purposes. Others insist that this is a stage in a natural cycle,
when the Earth atmosphere warms up, but will cool again in years to
come. Many people even believe this is God's wrath, punishing humanity
for its disobedience and abuse of nature.
Would the expectations of an iceless Arctic summer by 2013 turn out
to be right? Voyaging in the Arctic for two weeks without seeing floating
ice was unbelievable. Whatever the reason might be, global warming
is a fact and the ice meltdown is an ongoing process. We all ought
to do something about it, as individuals, institutions, governments
and global community.
When my 6-year old niece heard I was going to the North Pole region,
she asked: "Will you see Santa?" Well, I don't believe in
Santa anymore. But if he really lives there, I hope that in a few
years he will not be rowing a boat instead of riding a reindeer-pulled
sleigh.
