During the past several years, there’s not been as much ice on the Great Lakes. For the second
year in a row, there’s a lot more. The Great Lakes Radio Consortium’s Lester Graham reports:
With a colder winter this year, the Great Lakes are seeing more ice coverage. Ray Assel is a
physical scientist with the Great Lakes Environmental Research Lab. He outlines what he sees on
ice charts from the National Ice Center.
“Ice cover extent similar to the 30-year median ice cover. So, it’s really not that unusual.”
Last year also saw closer to average ice on the Great Lakes. But it seemed extraordinary because
of several mild winters before.
“I think what makes people think it may be unusual is because of the five winters previous to this
last winter, we’ve had below normal ice cover.”
Assel says for those who are looking for clues to global warming, year-to-year changes can vary
widely. Global warming has to be measured in decades.
For the Great Lakes Radio Consortium, this is Lester Graham.

Pull out a map and you’ll find the Great Lakes area holds resources that no other
place can claim.
The region is rich in lakes and forests and scenic views. But a road map just
covers the surface.
We know much less about what’s under the earth. Now, a team of geologists from the
Great
Lakes states is working to map the resources under the ground. The Great Lakes Radio
Consortium’s Erin Toner reports:
Look outside – look out your car window or into your backyard and try to erase
everything you
see. Take away the playgrounds and the concrete parking lots. Strip away the trees
and the grass
and the topsoil in your garden.
This is the way Kevin Kincare imagines the world. A picture of nothing except naked
landforms
– massive hills and cavernous valleys. All created by gigantic pieces of ice that
gouged and
ground their way down the globe from Canada. This would be the picture of Great
Lakes states
about 15-thousand years ago. It’s the picture Kincare is slowly putting down on paper.
“This is a big chunk of granite and you can see this one side is flat and looks
polished. The
glacier was moving across. There’s grooves right here. So this is the direction
the ice was
moving.”
Kincare is a glacial geologist with the Michigan Department of Environmental
Quality. Six years
ago, he helped start the Central Great Lakes Geologic Mapping Coalition. It’s a
group of
geologists from four states – Michigan, Indiana, Illinois and Ohio – and the U.S.
Geological
Survey. They’re working to put together a 3-D digital map of the region’s glacial
geology.
They’ll map everything down to the bedrock, which can be hundreds of feet below the
Earth’s
surface.
The first step in geologic mapping is compiling information from local maps. After
that it’s out
to the field.
At Tacy Brother’s Gravel Pit, a massive machine is sorting big scoops of earth into
piles of sand,
gravel and rocks.
Kincare is now working on mapping a small county on Lake Michigan. He says looking
at a
gravel pit is like looking at nature’s record of thousands of years of changes to
the planet’s
surface.
“That starts to pull the whole story together. How the ice retreated across the
county from east to
west and where all the rivers that were carrying the melting glacier ice and
depositing thick
sections of sand, and where the glacial lakes were, where all the silt and clay was
dropping out.”
Geologists say one of the most important uses for the maps is locating water
resources.
Nationally, Michigan ranks first in the number of people who use household wells to
get their
drinking water. Illinois, Ohio and Indiana rank among the top 15 in the nation for
household
water well use.
Gary Witkowski’s job is to protect the environment in his county in southwest
Michigan. He says
the first step in protecting groundwater is knowing exactly where it is.
“It’d be a tremendous help for us if we could just go to a resource like this and
pull that
information. Not only to us, but, I mean, even to the developer, it would be a
major plus that they
could look at.”
Knowing exactly what’s under the ground also helps planners build in the right
places. And it
helps them avoid building in the wrong places. For example, planners can put
neighborhoods
close to supplies of groundwater. They can discourage development on land rich in
minerals and
construction materials, such as sand and gravel. And they can make sure they don’t
build
industrial plants in places that are especially vulnerable to pollution.
Dennis O’Leary is with the U.S. Geological Survey. He’s helping Kevin Kincare with
the map.
“Those kinds of decisions that involve competing interests really can’t be made
rationally unless
there’s a body of knowledge, of fact, that relates to just what the question’s all
about and that’s
what these maps provide.”
But it could be awhile before people have access to maps this detailed. The four
states in the
mapping coalition and the Geological Survey all have to share 500-thousand dollars a
year for the
project. That means Kevin Kincare can map only one county every three years. It
would take
two centuries just to finish his state.
“We’d have to have a lot of medical breakthroughs for me to finish this project.”
Kincare says the maps are too important to wait that long. He says they need
20-million-dollars a
year from Congress. With that money, they could put together a complete geologic
map of the
Great Lakes region in about 16 years. Kincare says he’s not optimistic they’ll get
that kind of
money.

New research has dispelled some myths about African Americans and
their concern for environmental issues. The study shows that African
Americans are just as concerned about the environment as White
Americans,
if not more. The Great Lakes’ Radio Consortium’s Tracy Samilton
reports.
University of Michigan researcher Paul Mohai says many people assume
African Americans are less concerned than White Americans about the
environment. That’s because many African Americans have to deal with
urban issues. Issues like crime, poverty, jobs and education. But
Mohai’s study finds that African Americans care more about neighborhood
environmental issues like pollution than White Americans – and just as
much about global issues like endangered species and global warming. He
says the biggest surprise is, it’s not a recent development.
“It’s not that African Americans caught up, they’ve been
concerned about the environment for a long time, we just haven’t looked
at
the data!”
Mohai also finds that African Americans in Congress have better
environmental voting records than their white counterparts. He says the
study shows that African Americans make natural allies for environmental
groups and for voters who want an environmental advocate to represent
them
in Congress. For the Great Lakes Radio Consortium, I’m Tracy Samilton.

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.

Within three decades, summers in the Great Lakes states might feel more

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.

Scientists are talking about a new way to address global warming. Their idea is to take carbon
dioxide from coal-burning power plants and inject it deep into the earth. The Great Lakes Radio
Consortium’s Annie Macdowell explains:
It’s called carbon sequestration. The idea is to use a chemical process to remove carbon dioxide
from power plant emissions and pressurize it into a liquid form. The liquid would then be injected
into saline aquifers up to ten thousand feet below the ground.
The government wants to create 4 to 10 regional partnerships to study the possibility of carbon
sequestration. One of the potential sites is in the Illinois Basin. The basin extends throughout three
quarters of Illinois, into Western Indiana and Western Kentucky.
Robert Finley is the director of the Center for Energy and Earth Resources at the Illinois State
Geological Survey. He says carbon sequestration could be a good transition for the country as it
moves away from using fossil fuels.
“It would allow us to use coal in a more environmentally responsible way while we look toward the
future with additional use of renewables and ultimately, perhaps, going to a hydrogen economy.”
Finley says at this point, sequestration doesn’t work with other pollutants found in power plant
emissions, such as sulfur dioxide, nitrogen oxide, and mercury.

Some Midwest states are highlighted in a new report
that looks at what states are doing to reduce greenhouse gas
emissions. The Great Lakes Radio Consortium’s Chuck Quirmbach
reports:
The federal government wants no part of international
treaties aimed at reducing pollution linked to global
warming. But a report by the Pew Center On Global Climate
Change says about one-third of the states have taken significant
steps on their own. The study mentions Minnesota’s effort to
plant trees that may help reduce energy consumption and absorb
carbon. Wisconsin is praised for requiring large polluters to
report their carbon dioxide emissions.
University of Michigan professor Barry Rabe offered the study. He
says the budget deficits faced by many states may stifle additional work.
“And there may be an unfortunate irony here that at the
moment when political interest in doing something to
reduce greenhouse gases is greatest, the fiscal capacity to
fund some of these programs and implement them may be at a very,
very low point.”
The Pew Center says the state efforts are no substitute for a
comprehensive national plan. For the Great Lakes Radio Consortium,
this is Chuck Quirmbach reporting.

As leaders prepare for the World Summit on Sustainable Development in Johannesburg, Canadian environmentalists say their country is no longer considered
an important player on the world stage. The Great Lakes Radio Consortium’s
Karen Kelly reports:
John Bennett remembers when Canada was one of the so-called “good guys.” He’s the director for climate change and energy with the Sierra Club of Canada.
And he says 14 years ago, Canadian leaders were among the first to call for action on global warming. Now, the Canadian government is seeking exemptions
from the Kyoto climate change agreement.
“The leadership it’s showing is how do you wheedle out of an important environmental agreement? How do you weaken the agreement to the point that it’s
meaningless in order to make it cheaper and easier for Canada to achieve the targets.”
Environmentalists at home and abroad say Canada has been slow to take serious action.
Canadian leaders have delayed signing the Kyoto Protocol. They argue that Canada should be able to make fewer reductions in pollution because it exports so-called
clean energy – like hydroelectric power – to the United States.

A new poll indicates most Americans don’t like the Bush administration’s approach to global warming. The Great Lakes Radio Consortium’s Lester Graham reports:
The poll was commissioned by the Union of Concerned Scientists. It found that 75-percent of those polled disagreed with the President’s approach asking power plants and others to voluntarily reduce emissions such as carbon dioxide believed to cause global warming… and they rejected the Bush administration’s proposal that we simply
adapt to the changes global warming will cause. Alden Meyer is the Director of Government Relations for the Union of Concerned Scientists…
“This is true not only for three-quarters of the public as a whole, but for around two-thirds of those who voted for President Bush. So, as the leader of the Republican party he is greatly out of step with the rank and file base of his own party on the issue of global warming.”
The Union of Concerned Scientists says the Bush administration paid too close attention to energy industry officials and ignored the public when putting together its energy plan.
For the Great Lakes Radio Consortium, this is Lester Graham.
