Officials from every country in the
world have gathered in Copenhagen
this week to build the
framework for a global climate treaty.
One of the goals is to slow the
destruction of forests in developing
countries. Those forests process and
store massive amounts of carbon dioxide.
Ann Dornfeld reports:

Preserving forests will be a huge debate in Copenhagen. Poor countries want wealthier countries to compensate them for not cutting the forests for lumber and to convert it to farmland. To find out why that might be important, you have to visit a place like this peat forest on the Indonesian island of Sumatra.

(sound of the forest)

Forests like this one are home to orangutans, Sumatran tigers and Asian elephants. But these forests may be more important for what lies beneath their marshy floors. The peat is composed of thousands of years’ worth of organic material. Indonesia’s peat forests are storage units for much of the world’s carbon. And they’re being destroyed at an alarming rate.

Not far down the road, Greenpeace Indonesia campaigner Bustar Maitar looks out on a charred landscape. You’d never know a forest stood here just a few months ago.

“Is the no more ecosystem here. No more forest here.”

Only a few burnt tree trunks are standing. Sour smoke curls up from the blackened ground. Maitar says this fire has been burning for a month.

“Fire is coming from not from in the top of the ground, but the haze is coming from inside. It means it’s the underground fire, especially in peatland. And underground fire is very difficult to handle.”

Indonesia’s peat forests are rapidly being logged, drained and burned in order to clear the land for tree farms and palm oil plantations.

The peat can be dozens of feet deep. When it’s burned, the carbon it’s been storing is released as carbon dioxide into the atmosphere. All of that burning peat has made Indonesia the world’s third largest emitter of CO2.

Until recently, industrialized nations topped the list of greenhouse gas emitters. Now the United States shares that shortlist with developing nations like China, India and Brazil. As these countries industrialize, demand for timber and open space has stripped many of their forests bare. But leaders of developing countries insist their nations should be allowed to do what it takes to build their economies – even if that leads to climate change.

Paul Winn works on forest and climate issues for Greenpeace. He says the only alternative is for wealthy countries to pay developing countries to slow their emissions.

“If the industrialized world is serious about climate change, it’s essential. It just has to be.”

Winn says wealthy countries have pledged 45 billion dollars so far to help poor countries reduce emissions. But he says that’s just a start.

“If you compare that to what the industrialized world spent on protecting its banks and its financial institutions during the financial crisis, it’s a pittance. And it’s far more essential that they do it now. Because these forests are threatened, and the emissions that go up into the atmosphere are going to come back and bite the industrialized world if they don’t fund its protection.”

Some of the funding plans on the table at Copenhagen would still involve drastic changes to the world’s forest ecosystems. The UN’s current plan would give pulp and paper corporations in Indonesia carbon credits to convert peat forests into acacia plantations.

Winn says that’s the opposite of what needs to happen. Greenpeace and other environmental groups want industrialized countries to fund a moratorium on logging.

One complicating factor is the rampant corruption in many developing countries.

“It is a concern. And I would imagine that’s why many of the industrialized countries haven’t committed to funding.”

Winn says a thorough verification process would ensure that if countries allowed logging, they’d have to repay donor nations.

Winn is in Copenhagen to promote forest protection in the developing world. He says he doesn’t expect anything major to come out of this conference – but hopefully it will lay some groundwork.

Sending a City’s Garbage Up in Flames

Back in the 1980s and 90s,
dozens of communities across
the US built incinerators to
get rid of their trash. Many
of them financed the massive
furnaces with bonds they’re just
now paying off. And now that
those debts are off their books,
some cities are re-thinking whether
burning trash makes environmental
and economic sense. Sarah Hulett reports:

About 300 garbage trucks dump their loads each day at the nation’s biggest
municipal incinerator.

“You see the conveyor house going across, that’s conveying the fuel to the
boilers.”

That’s Brad Laesser. He’s the chief engineer at the Michigan Waste Energy
facility in Detroit.

The “fuel” he’s talking about is shredded-up trash.

And he says that’s the beauty of facilities like this. They produce electricity.

“So right now we’re putting out about 50 megawatts. But we can go to
here.”

Laesser points to 70 on the output gauge. That’s enough electricity to power
about half the homes in Detroit. And the leftover steam is used to heat and
cool more than 200 buildings downtown.

Sounds great, right?

Well, Brad Van Guilder of the Ecology Center says not so much.

“Be wary of people coming and talking to you about large, expensive magic
machines that are going to dispose of your waste for you.”

Van Guilder says municipal waste incinerators are major contributors to
smog, and spew dangerous pollutants like dioxin, lead and mercury.

And he says huge furnaces like Detroit’s make it nearly impossible to get
viable recycling efforts off the ground.

“Think about what’s in the trash that you throw out every day. One of the
most important components is paper and plastic.”

Both can be recycled. But Detroit has not had a curbside recycling program
for the past 20 years. That’s because the contract with the incinerator
required that all trash picked up at the curb be used to keep the furnaces
burning.

That changed this summer, though – when the contract expired. Now about
30,000 households are part of a curbside recycling pilot project. And there
are drop-off sites where people can take their recyclables.

(sound of recycling center)

Matthew Naimi heads an organization that runs several drop-off sites, and –
maybe surprisingly – he’s okay with the incinerator. Naimi says he sees
trash disposal and recycling as two separate industries.

“I realized that if we shut the incinerator down before we got a good
established recycling program running, we’d be burying our recyclables
instead of burning them.”

And officials with Covanta – which runs the Detroit incinerator – agree that
recycling and incineration can work together.

Paul Gilman is the chief sustainability officer for Covanta. He says landfills
are the problem – not recycling.

“Landfills and energy-from-waste facilities, that’s where the competition is.
It isn’t at the upper step of recycling.”

He says cheap landfill space makes the economics of incineration difficult.

But he’s hoping that could change with the passage of a climate change bill
in Washington. Gilman says in Europe and Asia, trash incinerators like
Detroit’s don’t get treated the same way as power plants fueled with coal or
natural gas.

“So in Asia, under the Kyoto protocols, a facility like this actually generates
what are called greenhouse gas credits. They’re reducing greenhouse gasses
by the act of processing solid waste and keeping it from going to a landfill.”

Where trash produces methane – a potent greenhouse gas.

But the people who want the incinerator shut down say they don’t believe
burning trash is the greener way to go. They want the city to landfill its
waste while it builds an aggressive recycling program.

So far, they’re not getting what they want from city leaders.

The board that oversees how Detroit handles its trash recently voted to go
with incineration for at least the next year.

Backyard grilling is a great American summertime tradition. But, there’s some concern about grilling contributing to air pollution. Lester Graham reports you can reduce the pollution… it all depends on what you use:

So, let’s say you’ve got your charcoal. And now you’re squirting it with lighter fluid to get the fire going.

“Oooo. (laugh) Well, lighter fluid contains something called volatile organic compounds and helps to form a pollutant called ground level ozone.”

Beth Gorman is with the the Pima County Department of Environmental Quality in Tuscon. She says that ozone contributes to smog.

“This is a bad thing that we don’t want to breathe.”

And, lighter fluid residue can end up getting on your grilled veggies or burgers.

Gorman suggests a charcoal chimney which can get your charcoal lighted in no time, or an electric charcoal starter.

If you’re thinking a gas grill pollutes less, experts say when you consider the total carbon footprint, charcoal wins because it comes from a renewable resource: trees.

Climate change has already brought
warmer temperatures, rising sea
levels and melting glaciers. Now,
researchers believe global warming
will cause major shifts in wildfire
patterns around the world. As Sadie
Babits reports, scientists hope to
predict where future wildfires will
light up:

Trying to predict where wildfires are likely to start decades from now, is
kind of like getting a full body scan.

(sound of medical scanner)

Except instead of a medical scanner, scientists scanned the earth using
satellite data, climate models and the history of present day wildfires to
map out global wildfire patterns.

“The impacts of climate change on wildfires are expected to be widespread
around the world.”

Katherine Hayhoe is a climate scientist at Texas Tech University. She’s part
of a group of scientists that has for the first time, tried to project where fire
hotspots will crop up around the world. She says they found that climate
change will affect wildfire patterns.

Hotter temperatures and rain and snow coming at different times in the
year or perhaps not at all, will mean forests and grasslands will dry out
quicker – becoming tinder boxes for fire.

In the next 30 years, scientists believe that the Western U.S. will continue
to see catastrophic fires like the recent blaze in Santa Barbara, which
destroyed 80 homes.

In the next 60 years, they predict wildfires will increase in the Corn Belt and
spread into the East Coast.

Hayhoe says having an idea of how wildfire patterns will shift will help
communities better prepare.

“We can never eliminate the risk of climate change entirely but by making
wise choices and planning strategically we can minimize those risks.”

Some communities are already taking steps to prevent wildfire. The city of
Bend, Oregon was one of the first in the country to launch a public
education campaign to get homeowners to fire proof their homes. The
program, called FireFree, started more than a decade ago, after a massive
wildfire burned nineteen homes and scorched thousands of acres.

“It was something that scarred our community.”

Gary Marshall is the deputy chief of Bend’s Fire Department.

“We have this history of people wanting to live outside the urban area and
live out in rural areas, where they can see the deer and be out in the trees
and live that lifestyle that most Americans who move out to the West want
to be a part of that.”

Bend lies in what’s known as wildfire alley. Every year there are dozens of
fires that crop up either from lightning strikes or from people. The flames
are fed by dried out grasses and forests so dense you can’t see through
them. Add homes to the mix and you have a recipe for disaster not just
here but throughout the West.

But Marshall says the Fire Free program is working.

(sound of a truck driving on a dirt road)

County forester Joe Stutler and Gary Marshall drive me through
neighborhoods outside Bend. We stop first at an upscale suburb called
Coldera Springs. Everyone here has volunteered to fire proof their new
homes.

But just down the road, there’s a much older suburb and a lot of trees that
have been thinned out.

Sadie: “You can’t see through the trees it’s so dense.”

Joe: “You can’t walk through.”

Gary: “And a firefighter won’t go in there. You’d write that off. So if you
don’t take care of it, the fire will.”

That’s a picture that climate scientist Katherine Hayhoe hopes to avoid.
She says having a long term view of where wildfires might pop up could
help communities to start now and follow Bend’s lead.

It took Bend years to get most of the homeowners here to take
responsibility, and give their homes a fighting change to survive a
devastating blaze.

Getting People to Stop Burning Trash

Getting rid of your trash in the city
is easy. Take it to the curb on pickup
day and the city does the rest. In rural
areas, many people don’t have garbage pickup.
So they burn their trash. And that causes
pollution. Todd Melby tells us about one
place that’s trying to change its burning
habits:

Getting rid of your trash in the city is easy. Take it to the curb on pickup day and the city does the rest. In rural areas, many people don’t have garbage pickup. So they burn their trash. And that causes pollution. Todd Melby tells us about one place that’s trying to change its burning habits:


Robert Olsen lives out in the country. He used to burn his garbage. But not any more.


(Pickup hatch opens)


On this windy morning, Olsen has driven his pickup into town to dump his trash.


“I think this is probably a week’s worth for us.”


He grabs the blue plastic bin from the back of his pickup and dumps it into a green Dumpster.


“Not too difficult.”


Olsen runs the environmental office here in Lincoln County, Minnesota. It was his idea to set-up nine Dumpsters throughout this sparsely populated county. He did it because he knows that burning garbage pollutes.


“The issue is that when you burn garbage at home, in the country, the first people or persons who are going to experience any harmful effects from that garbage are going to be you.”


That’s because a lot of trash — including even plain old paper — contains chlorine that produce dioxins when burned at home. Plastic is even worse.


Mark Rust is a solid waste expert with the Minnesota Pollution Control Agency.


“If you’re using a burn barrel or fire pit or you’re burning garbage in any way on your own property, you’re creating a perfect factory for producing dioxins.”


Smoke from burn barrels and fire pits are now the leading source of dioxins in air pollution. Some studies have connected dioxins to cancer. Burning garbage is especially bad because there are no anti-pollution scrubbers on do-it-yourself burners.


“With a burn barrel, it’s all right there.”


Melby: “It all just goes right up into the air?”


“Into the air, into the soil. Ultimately, we’re going to be taking it in on the dinner table.”


Most states still allow people living in the country to burn their garbage. In Minnesota, only farmers and those without access to affordable garbage pickup can burn. A 2005 survey found that about half of the people living in rural Minnesota burn at least occasionally.


Which is why the state offered rural counties some start up money to get people to burn less.


Rural residents in Lincoln County, Minnesota have had access to drop-off sites for seven months now. When the program started, haulers took away about 8 tons of trash every month. Now it’s up to 15 tons.


Back at one of the county’s drop-off sites, Clarence Lietz is getting of his Buick and grabbing newspapers for the nearby recycling bin. What doesn’t get recycled, gets burned, he says.


“What garbage we have like small things for the yard we just burn right at home, you know. I’d say about a five-gallon pail full or something like that.”


Another elderly customer — she didn’t want her name used — says she burns junk mail and envelopes at home.


“Papers. That’s all you can burn. I don’t burn garbage.


Melby: “And why don’t ya?”


“It’s not right to burn garbage. It don’t burn any good anyway.”


Melby: “Why isn’t it right to burn it?”


“You know why, don’t cha?”


I do now.

Twenty years ago this year, the
country watched its oldest national park
go up in flames. Looking back, scientists

National Park were the signal fire of
climate change. Researchers have been
working ever since to understand this
relationship between climate and wildfire.
Sadie Babits reports on two scientists
searching for clues to ancient climates,
using trees as their guide:

Jennifer Pierce wears work boots as she plows down a steep slope in a
ponderosa pine forest.

(sound of walking, twigs breaking)

Her blonde hair is tucked up under her Boise State bronco cap, but it keeps
sneaking out. She has to keep brushing it back under. She and her
colleague David Wilkins are professors who work for Boise State
University’s Geosciences Department. They’re in the middle of tall pines in
a forest just outside of Boise, Idaho. Suddenly she’s crashing across the
brambles and heads for this tree.

“Oh that’s a great one! Wow! Sweet!”

She drops to her knees and shows me how this tree has been scarred by
fire.

“You see this little V shaped cat face here at the bottom of the tree that’s
blackened? So during a fire when the bark of the tree gets damaged that
preserves a record of the fire as a scar on the tree.”

Pierce says since the tree has annual growth rings, she can tell when the
tree got burned.

It’s one way Pierce and Wilkins reconstruct the fire history of this forest.
It’s a key to understanding how climate has affected forest fires in the past.

“I think as we move into a likely warmer and drier future, it’s going to be
increasingly important to understand the relationship between climate and
fire.”

She says climate is the primary control for wildfires. As the West warms,
there’s less control. Recently, that’s meant a lot more wildfires.

(popping sound) “There you go!” (sound of a drill bit going through the tree
with sound of birds and forest)

David Wilkins is twisting an auger into the tree.

“It’s a good upper body workout!” (laughs)

It’s a way to take a sample of the rings of this tree. Within a half-minute,
Wilkins’ auger is stuck. The tree is rotten inside. An eight-inch core is all he
gets.

(sound of drill bit coming out of the tree)

Jennifer Pierce takes a look at this sample Wilkins twisted out. The rings –
some light, some dark – reveal just how the tree has responded to moisture
and temperature.

“If you have a tree that kind of is at the edge of its comfort zone so to
speak, it will be more of a sensitive recorder of those environmental
stresses. See this one looks pretty good.”

Tree rings aren’t the only clue these scientists use to reconstruct historic
climates.

(scraping sound)

“I didn’t bring my big shovel. I kind of feel naked without it.”

Pierce scrapes away dirt and she finds bits of charcoal. She can sometimes
use charcoal for radio carbon dating. But these won’t do.

“But, um, I wouldn’t use them for dating because you want to make sure
that the charcoal is stratographicly in place and that you haven’t had
critters burrowing and mixing things up.”

Charcoal can be dated much further back than the tree rings. It helps
Pierce and Wilkins understand what happened here thousands of years
ago. With samples from other scientists, they’ll get a snapshot of ancient
climate and how it affects wildfire.

And possibly determine what climate change will mean for forests in the
future.
