The Arctic is melting this summer.
But, that melting is not as severe as it
could be. Lester Graham reports a haze
filters out some of the sun’s rays:

Every year there are forest fires in Alaska, Canada and Siberia. Most of them are
started by lightning strikes. The smoke from the forest can be carried by the winds
across the Arctic. It slows the melting of the ice just a bit.

Bob Stone works with the National Oceanic and Atmospheric Administration.

“It does act as a filter. It extinguishes some of the direct sunlight that would otherwise
impinge on the surface of the snow (and) ice.”

So the smoke shades the arctic from the sun. It’s still not really good news.

Yes, melting slows a bit – but scientists think as global warming continues, we’ll see
more forest fires. That means more of the greenhouse gas CO2 is released, and, fewer
trees soaking up CO2.

Just when you thought polar bears in the United States were safe under the Endangered Species Act… they’re facing a new threat. The Bush Administration has announced regulations that allow oil companies to harass polar bears while they explore for oil off the coast of Alaska. Richie Duchon has more:

Oil companies can’t kill polar bears. That still brings a penalty. But they are legally protected from any accidental harm caused by trucks, boats and experiments that alter the polar bear’s environment.

The U.S. Fish and Wildlife Service’s Bruce Woods says oil exploration is not much to worry about.

“Believe me, you won’t find more concern for the polar bear anywhere than you will in this office, but we just don’t really believe that this activity at this level poses any significant threat. The threat to the polar bear is the loss of sea ice.”

Environmental groups are furious. They say the loss of sea ice from global warming is a threat to the polar bear, but they say we need to minimize other threats with a moratorium on oil exploration.

Polar Bear Protection Spurs Lawsuits

The federal government has announced that
it’s listing the polar bear as a threatened species.
Biologists say the rapid loss of sea ice from
the warming climate is putting the bears at risk.
Mark Brush reports the government is now facing
legal action from some conservative groups:

In the announcement Secretary of the Interior Dick Kempthorne tried to make it clear –
the listing doesn’t mean the government is regulating greenhouse gases. He says the
listing can’t be used to stop oil and gas drilling or to go after industries for releasing
carbon dioxide.

Reed Hopper is the principal attorney for the Pacific Legal Foundation – a conservative
public interest group. He says he still expects lawsuits from environmentalists. And that
the Secretary can’t control how the courts will interpret the new listing.

“If the activists are able to use this as they intend, to challenge industrial activity in the
United States, the ultimate effect on the average person is going to be an increase in
energy costs, transportation, fuel, food and housing.”

Hopper says his group is planning to go forward with a lawsuit of their own – opposing the listing.

Open Water in the Arctic

Polar bear researchers off Alaska’s
northern coast found striking differences in
sea ice conditions recently. Lori Townsend
reports:

Dr. Steven Amstrup is a polar bear expert and USGS wildlife biologist.

“This is the first time in my 28 years working up here this time of year that we’ve seen anything like
this.”

Amstrup is conducting yearly research on polar bears in Alaska’s Arctic. He says getting out to pack ice usually means
flying over a narrow expanse of open water called a lead.

“But this year that lead is wide open, we have no idea really how wide it is, but its way too far for us to
fly across. So we’ve been limited to hunting in a fairly narrow band of ice that’s fairly near shore.”

Amstrup says the open water is consistent with warming conditions that result in
thinner ice. Polar bears rely on pack ice for hunting seals and other marine
mammals.

Spring floods are hitting some parts of the country,
and the National Weather Service predicts high waters might hit
more states. Chuck Quirmbach reports:

There were record snowfalls in some northern, eastern and western states during the winter. Soil
moisture in some areas is very high. With the potential for spring rainstorms, the National
Weather Service says conditions are above average for flooding. Deputy Director Vickie Nadolski
says the threat will last a while.

“As you see the temperatures start to warm up in the summer, then certainly the ground will start
to dry out a bit more, but right now it’s quite saturated.”

Nadolski urges the public to listen to warnings of flash floods and river flooding. She warns
against driving or walking into flood waters.

The National Weather Service says soil moisture is not as high in states with prolonged droughts,
and that a lot of rain or snow there will bring temporary improvement to local reservoirs.

  • Melting glaciers as seen from aboard the Fairweather Express II in Glacier Bay, Alaska (Photo by John Ryan)

A National Park might not be the first place
you’d expect to turn into a crime scene. But John Ryan
found one – of sorts – on a boat touring Alaska’s Glacier
Bay National Park:

Transcript

A National Park might not be the first place
you’d expect to turn into a crime scene. But John Ryan
found one – of sorts – on a boat touring Alaska’s Glacier
Bay National Park:

(music)

Scene of the crime. Glacier Bay National Park. 9 o’clock on a sunny Saturday morning.

The crime: Global warming. You know: ice caps melting. Sea level rising. Deserts and
disease spreading. Scientists say it’s big, very big.

(music)

Intergovernmental investigators have ID’d the perpetrator: it’s us. Emissions from fossil
fuels like coal and oil have started heating the earth.

But here on the Fairweather Express II, you’d never know it. Park ranger Kevin Richards
is at the mic, entertaining passengers as we cruise past mile-wide glaciers
in the sun.

“That snow fell when Thomas Jefferson was signing the Declaration of
Independence.”

Richards tells the crowd how the glaciers have retreated 60 miles in the past 200 years.

But he hasn’t once mentioned global warming.

In the audience, Anchorage pathologist James Tiesinga smells a rat.

“The rangers seem very reluctant to say the words ‘global warming’, they skirt
the issue of why the glaciers are receding. I can’t help but wonder if the Park Service
has communicated the message to its employees, ‘don’t bring this up, it’s a hot topic’.”

And I notice the visitors’ newsletter put out by the park talks in depth about the changing
glaciers, but fails to mention that the climate is being changed by humans.

During a break in the naturalist’s stand-up routine, Tiesinga asks why there has been no
mention of global warming? Are we witnessing a coverup?

(music)

As huge chunks of ancient ice tumble into the bay, the Park Ranger, Kevin Richards, says, no,
there’s no censorship of climate science.

“Until very recently, yeah, if you’re working for the government, you
probably didn’t talk a lot about it. But now it’s okay, it’s an open forum right now.”

He says he’ll get to the connection
between melting glaciers and a warming earth near the end of his talk, but it’s a lot more
complicated than you might think.

“We just can’t talk about tidewater glaciers the same way we do about
terrestrial glaciers. It’s not the same process.”

Here’s why it’s not the same: tidewater glaciers have snouts that stick out into the ocean. Terrestrial glaciers are
land-locked. Richards goes on to say that land-locked glaciers in the mountains above
Glacier Bay are shrinking under a warming climate. But he says the dramatic loss of 60
miles of ice from Glacier Bay itself is not a sign of global warming.

(music)

To fact-check the on-board nature talk, I called up Roman Motycka.
He studies glaciers at the University of Alaska-Fairbanks’ Geophysical
Institute. He confirmed that global warming is hitting most Alaskan
glaciers hard.

“90% of the glaciers in South-Eastern Alaska are wasting away, and that’s
complicated, but primarily due to global warming.”

So why aren’t tourists in Glacier Bay hearing that when they witness fall
ice chunks fall into the ocean?

“It’s really complex there. Here’s what happened when all
that ice got lost.”

Motycka explains that tidewater glaciers have their own cycles of
advance and retreat. In a nutshell, when the snout of a glacier ends up floating in deep water, it becomes inherently prone to calving – that is, dropping icebergs – independent of the climate. And that’s what’s happened in Glacier Bay. So, in other words…

“Your naturalist was right, the terrestrial glaciers are the
ones that are more important to look at in terms of straight climate
change.”

(music)

Back on the Fairweather Express II, Park Ranger Kevin Richards
finishes his day at the mic talking about global energy consumption and
making a plea for people to protect the environment back home,
wherever they come from.

So in the end, park rangers are still the nature lovers in funny green outfits you might
remember from your childhood. And as this episode of Thaw and Glacier comes to a
close, all is well in Glacier Bay. Except for a little thing called…

(music)

…global warming.

Polars Bearing Weight of Global Warming

If global warming is represented by one symbol, it
might be the polar bear. It’s an icon of the North
Polar region. Now, federal biologists have asked that
polar bears be listed as threatened under the Endangered
Species Act. They’re the first species to be considered
for protection because of global warming. Reid Frazier
reports that the polar bear might help connect the
abstract idea of global warming with the concrete
actions of people in their homes:


(Sound of kids talking to polar bears)


Parents and children gather around a large window to watch Nuka and
Koda frolick in the aqua water tank. The polar bears are having a
blast. They splash and dive, play with foam toys, and duck their heads
underwater to look around. The young brothers are only two-years-old
and already they weigh 600 pounds each. These bears, born and raised in
zoos, eat about 18 pounds of food a day. But, their cousins in the wild
are finding food much harder to come by these days.


Henry Kacprzyk is a curator at the Pittsburgh Zoo. He wants crowds to
know just how fragile the bears’ situation is. Walking along a
boardwalk near the exhibit, Kacprzyk points to a sign. It welcomes
visitors to “Piertown,” a replica village designed to resemble a
growing Alaska fishing town:


“The thing to note here is the human population has increased from 110
to 1,712, on the other side the bear population has declined, from 1,784
to 368, which, the message there is, as humans increase in population in some
of the bears’ habitat, the bears go down. It’s a sad but true fact.”


The situation for the world’s 25,000 polar bears is increasingly dire.
Besides people crowding them out, overfishing has depleted arctic
waters of fish for seals to eat, and seals are the bears’ main source
of food.


But here’s the biggest problem: the polar ice cap is melting. That’s
depriving the bears of a main hunting ground. The vast majority of
scientists attribute this to global warming. They say the warming is
caused by a buildup in the atmosphere of greenhouse gases from burning
fossil fuels.


Scott Schliebe is a biologist with the Fish and Wildlife Service. His
team recommended polar bears be added to the protected list because
they’re losing their habitat. Schliebe says the bears need sea ice to
hunt seals. No sea ice means no food for the bears:


“They will wait at a breathing hole for a seal and wait until the seal comes up
and then catch the seal. They’re not effective at hunting seals in open
water, seals have the severe advantage of being able to outpace the polar bears in that environment.”


In areas with receding ice, polar bears are already hurting. Scientists
see the world’s polar bear population shrinking by a third in the next
50 years.


Back at the Pittsburgh zoo, the polar bears are a big hit with
visitors. They helped the zoo break an attendance record last year.
Curator Henry Kacprzyk hopes visitors tie their own behavior with the
plight of the arctic:


“It’s sometimes little things, as a general family, for instance, what you
can do is conservation of fuel and energy, keeping your lights off,
maybe living closer to work is a great idea. By choosing conservation
you can make a difference.”


The bears are popular with Cindy Jagielski, who’s visiting the zoo with
her small grandchild. Jagielski’s worried the bears will one day become
extinct but she admits she doesn’t know much about global warming:


“Maybe it’s just the Earth’s changing. I don’t know that industry has
anything to do with the melting of the ice there. Maybe it’s just a
natural occurrence.”


Despite some lingering doubts over what causes global warming,
polar bears are a popular cause. The Fish and Wildlife Service has
already received 40,000 emailed comments since it proposed protecting
the species. The Service will make its final decision on protecting
polar bears by next January.
