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.

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.

Climate Change and Wildfires

Twenty years ago this year, the
country watched its oldest national park
go up in flames. Looking back, scientists
believe the 1988 fires of Yellowstone
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.
