It’s normal to want to protect special
places in nature. But in some cases, these
places are disappearing simply because of nature.
Christina Morgan reports on an ancient spot that
might disappear in our lifetime. The people who
love it want to save it, but they might have to
let it go:

For four generations, J-me Braig’s family has visited a rare
site, a bog left behind by glaciers thousands of years ago.

“As a child, I used to go out there and play on it, with my
grandmother, and we would pick cranberries; my brother and I would play on it. ”

Braig says her grandmother used to take a boat out to the bog
in a lake in Ohio. Her grandmother made pies and wine with
the cranberries.

Braig is a lake historian who’s worried about the bog. That’s
because it’s shrinking.

But before we talk about why it’s shrinking, though, it’s important
to know what makes this tiny area special.

Webster’s dictionary defines a bog as soft, waterlogged
ground. This bog, Cranberry Bog, is soft and waterlogged.
But it’s not ground. There’s no dirt. The bog is a 10 acre
patch of sphagnum moss.

Most bogs surround a glacial lake. Instead, Cranberry Bog is
surrounded by a lake, and floating. Here’s what happened.

Nearly 200 years ago, crews digging in an ancient river bed
created a reservoir to feed the Ohio and Erie canal. The
reservoir filled, the mossy bog floated to the surface. How or
why it stayed, no one knows.

“An absolute oddity. It shouldn’t be here.”

Greg Seymour is with the Ohio Department of Natural
Resources. He says the ancient bog is home to likely the only collection
of plants of its kind in the world.

More than 150 plants, a
handful native to Canada. Nudged southward by the glacier,
the plants are tricked by the cool bog mat into thinking they
never left home.

The bog is shrinking for several reasons. Waves from passing
boats loosen the bog mat. Storms topple trees
which rip out chunks of the mat. But Seymour says the biggest
threat is the bog’s chemistry, which makes the site its own
worst enemy.

“The number one factor is going to be the chemical reaction
between the alkaline lake waters and the acidic bog.”

The pH balance is off – way off. Cranberry Bog is doomed to disappear, probably within 30
years.

But area historian J-Me Braig remains upbeat, saying ever
since she can remember, someone has had a scheme to save
Cranberry Bog.

And sure enough, there is a new group determined to preserve the
ancient bog.

George O’Donnell leads Friends of Cranberry Bog. He and
others think one way to generate interest in the site, is to inventory of all that the bog has to offer.
Such an inventory is being done by the bog’s neighbor 8 miles
to the north, Dawes Arboretum.

Tim Mason is the manager of natural resources there. He says even
if the inventory and other efforts to preserve the bog fail, they
have a plan B. Dawes created a restoration area where pieces
of Cranberry Bog that break off are placed.

“We can just hold on to what’s there. It takes thousands of
years for the peat moss material to grow; so to create that is something we would certainly not see in
our life times.”

Saving the bog – or just preserving its pieces – are a long shot.
Yet the efforts persist. Historian J-Me Braig is one of many people
who hope for success. But even Braig admits, after more than
10,000 years, Cranberry Bog has had a pretty good run.

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.

A non-profit group is working to preserve part of the region’s glacial history. The Great Lakes Radio Consortium’s Christina Shockley explains:


The group is building a national scenic trail where a glacier stopped and receded thousands of years ago in Wisconsin. The same glacier formed Lake Michigan. Landscape formations along the trail vary from cone-shaped hills to long, snake-like hills.


Nancy Frank is with the Ice Age Park and Trail Foundation. That’s the group working on the project. She says sometimes there’s no definite line of where the glacier was.


“It may be a band of about three miles or so of glacial material, that forms what they call the terminal moraine, which is as far as that glacier went.”


Frank says work on the trail began in the 1950’s. So far, 600 miles of it are done; at least 400 miles are left to go. A bill before Congress would make it easier to complete the trail. The ice age trail is one of only eight scenic trails in the nation.

Officials Overlook Illegal Dumping

Americans generate 14-billion tons of waste each year. Most of that trash winds up
in landfills,
some of it is recycled. But some of it slips through the cracks, winding up in
illegal trash dumps
throughout the country. Environmental officials are cleaning up a 7-acre pile of
waste that was
overlooked for so long that it caught fire a few years ago — and kept burning. The
Great Lakes
Radio Consortium’s Brad Linder reports:


Tucked away in a non-residential section of South Philadelphia, just around the
corner from the
Philadelphia Airport, lies a heap of construction debris. The material was dumped
here years ago
by a demolition contractor, and left to rot…


Occasionally sparking up into flame, the densely packed wood, metal, carpet, and
other debris has
been smoldering below the surface for the past few years.


Down the street is a police impoundment lot, and the Water Department’s waste
treatment site.
And directly across from the dump is a series of community gardens.


Edward Burnabiel’s been tending vegetables here for two decades.


“We raise everything, tomatoes, peppers, eggplants, scunions, onions, celery, squash…”


Burnabiel spends six days a week in his garden. He jokes that it would be seven if
his wife didn’t
drag him to church on Sundays.


A few years ago, he and his fellow gardeners noticed something unusual at the trash
pile across
the street. Every now and again, smoke would billow up from the site — and combine
with the
stench from the nearby sewer plant.


“The smell was awful when it started burning. It would stink, even to go by. It’s
bad enough we
have to smell the poop down there, but then we got to smell that too!”


The gardeners complained to the city. But the trash has been around for well over a
decade.


Kathleen McGinty is Secretary of the Pennsylvania Department of Environmental
Protection.
She says the contractor responsible for the mess has long-since disappeared. That
contractor,
Harold Emerson, also skipped out on a 5-million dollar fine for illegal dumping.


“About thirteen years ago, Mr. Emerson was contracted to take some houses down in
Philadelphia. As part of the deal, for a one year window of time, the agreement was
that he could
temporarily store some of that construction debris here. What Mr. Emerson
conveniently forgot
was the temporary part. And he just took off without ever having done that.”


Today, the trash pile is sometimes referred to as the “Emerson Dump.”
Environmentalists
worried that the burning trash could be a health risk. Construction debris can
include hazardous
chemicals like arsenic. But city Managing Director Phil Goldsmith says tests showed
the fumes
weren’t dangerous. Still, he says cleanup was long overdue.


“Fourteen years for something like this to be sitting around is far too long. And
it’s become a
nuisance. It’s been a place where our fire department has had to come to put out
fires. We should
not have allowed this to happen in the first place. And once it happened, we should
not have
allowed to have it continue here for so long.”


The Emerson Dump is hardly unique. There are illegal dumps all across the country.
But most
are hidden in forests or other out-of-the-way areas, and don’t have the high profile
that comes
with a flaming pile of trash in an urban setting.


Allen Hershkowitz is with the environmental group, the Natural Resources Defense
Council. He
says illegal dumping is often overlooked for more serious environmental concerns,
such as air
and water pollution, or global warming. But he says it’s still a problem
authorities must deal
with.


“In the next 10 years, this country will have to manage about 140-billion tons of
waste of
different types. More than 2/3rds are managed in ecologically inferiors ways,
landfills, surface
impoundments, or incinerators. When you illegally dump waste, you make it that much
harder
for that material to wind up being recycled or properly disposed of.”


Hershkowitz says illegal dumping is directly related to the cost of proper waste
disposal.
Dumping was most prevalent in the late 70s and early 80s, when strict environmental
regulations
led many landfills to close, driving up the costs of waste hauling. Illegal dumping
still occurs,
Hershkowitz says, but less frequently.


Pennsylvania officials are still hunting for demolition contractor Harold Emerson to
force him to
pay his 5-million dollar fine.


But in the meantime, state and city taxpayers are funding a 3-million dollar cleanup
effort. The
fire’s been extinguished, but cleanup efforts are expected to continue through the
end of the year.

Researchers Forecast Region’s Warmer Future

Warmer weather might sound like a welcome reprieve to a lot of people spending early spring in the
Midwest. But a team of researchers is warning that in years to come, warming trends in the Great
Lakes region could be bad news for business, and for people’s health. The Great Lakes Radio
Consortium’s Sarah Hulett reports:


Climate change is not a phenomenon that’s unique to the Great Lakes
region. But University of Michigan biologist George Kling says there’s
good reason to look to the Midwestern U.S. for early clues about global warming
elsewhere.


“The middle part of North America, including the Great Lakes region, warms, or has warmed in the
past, at a slightly higher rate than the globe overall. Because we’re right in the center of a continent,
and there’s less buffering impact from the oceans. So coastal areas tend to warm a little bit less, at
a slower rate, continental areas warm at a little bit faster rate.”


Kling and other researchers from the Union of Concerned Scientists, and
the Ecological Society of America, spent the last two years looking at
some of the changes that can already be seen in the region: shorter winters,
higher temperatures, and less ice on the Great Lakes during the winter
months. And Kling warns that extrapolating these trends out over the coming
decades paints an ugly picture:


“These climate changes that we project in our new report will magnify
existing health and environmental problems, and may stress our economy.”


Asthma that’s aggravated every time a heat wave hits, increased competition
for groundwater as dry weather saps wells, and financial losses in communities that once relied on
winter tourism are all distinct possibilities. And the report warns that more visible changes to the
landscape might also
be on the way.


Donald Zak teaches ecology at the University of Michigan. He says during
past periods of warming, trees actually moved north to survive. But Zak
says that kind of tree migration may no longer be possible.


“Ten thousand years ago, when species migrated across the region, there
were very few barriers to migration that we have now placed in the landscape –
like large areas of agriculture, large areas of urban development. Those
will become barriers to migration that didn’t exist following the close of the
last ice age.”


Theories about causes of the warmer weather are well known: heat-trapping
gasses – mostly carbon monoxide – are spewed from coal-fired power plants
and gasoline engines. And continued deforestation and urban sprawl help
ensure mother nature never catches up with processing it all. But the researchers who worked on
the project say solutions are available to slow the effects of global warming. The report makes the
case for raising fuel economy standards for cars and trucks. David Friedman with
the Union of Concerned Scientists says right now, there are more than 30 models of cars on the
market that get more than 30 miles per gallon. The problem, Friedman says, is that those are
mostly compact cars that don’t meet the needs of people who are shopping for pickups, minivans,
and SUVs. Friedman says for those customers, there’s no way for them to use their
wallets to show their desire for more fuel-efficient vehicles.


“When your choice is between 17 and 18 miles per gallon, that’s not a
choice. You’re probably going to choose the vehicle based on the color
and the cup holders, not the fuel economy, when the difference is only one
mile per gallon.”


Some critics say the incremental changes that would result from raising
fuel economy standards would have almost no impact on global warming.
But researchers on the Great Lakes study say resistance from policy makers
and corporate leaders doesn’t have to hamper efforts to slow the effects
of climate change. They say even choices at the household level – like
carpooling and conserving energy can help lessen the damage.

RESEARCHERS FORECAST REGION’S WARMER FUTURE (Short Version)

Within three decades, summers in the Great Lakes states might feel more
like summers in Kentucky and Oklahoma. That’s according to results of a
two-year study conducted by a team of Midwest and Canadian scientists.
The Great Lakes Radio Consortium’s Sarah Hulett reports:


The study was conducted by the Union of Concerned Scientists and the
Ecological Society of America. Researchers looked into trends that have
already shown up in the region – including shorter winters, higher
annual average temperatures, and declines in winter ice on the Great
Lakes. The study projects potential problems for the region. Anglers
might find certain fish no longer thrive in warmer waters, and
communities that rely on winter tourism might find themselves hard hit.


University of Michigan biologist George Kling is the lead author of the
report. He says the findings point to a warming trend unlike anything
the planet’s seen.


“In the next 100 years, we will have the same amount of warming that has
occurred since the last Ice Age – 10-thousand years ago.”


The report outlines approaches for slowing the effects of global
warming. They include reducing greenhouse emissions and investing in
renewable energy.
