A new report says the Midwest is one of the most polluted areas in the country when it comes to soot pollution from diesel exhaust. The environmental research and advocacy group the Clean Air Task Force says much of this pollution could be cut using available technology. The Great Lakes Radio Consortium’s Elizabeth Braun reports:
Three Midwestern states: Illinois, Ohio and Michigan are in the Task Force’s top 10 worst states for diesel pollution. The task force says inhaling diesel soot leads to thousands of heart attacks, early deaths and asthma cases. But, they say the trend can be reversed by limiting the amount of exhaust that’s released into the air.
They say one way to do this is to retrofit schoolbuses to reduce emissions. Renate Anderson is with the American Lung Association. She says children are the most at risk from diesel exhaust.
“School buses… that is a specific danger zone. Children have developing lungs, they tend to breathe about fifty percent more per pound of body weight than adults do.”
The task force also recommends passing legislation to limit how long diesel-engine vehicles can idle. The state of Minnesota has a no-idling policy for school buses, and Illinois lawmakers are currently working on such a measure.

A recent study seems to indicate that wildlife recover from mercury contamination pretty
quickly once emissions restrictions are in place. The Great Lakes Radio Consortium’s
Lester Graham reports:
The study reveals nearby mercury pollution can end up in local fish and wildlife. It’s
been thought that emissions from incinerators and coal-fired power plants spewed
mercury into the atmosphere where it settled out far away from the source.
In this study, published in the journal Environmental Toxicology and Chemistry,
University of Florida scientists determined that mercury in local wading birds rose and
fell with emission levels from nearby sources. Tom Atkeson coordinates the mercury
program at the Florida Department of Environmental Protection.
“Where we were able to make emissions reductions, we’ve been fortunate enough to see
declines in deposition and then very rapid responses in the aquatic system, lower levels of
mercury in fish and wildlife.”
Environmentalists say this means the Bush proposed cap and trade program for reducing
mercury emissions could lead to local mercury “hot spots” across the nation.
For the Great Lakes Radio Consortium, this is Lester Graham.

Environmental groups are turning to national ad campaigns to get automakers to
make more fuel-efficient vehicles. And they’re singling out Ford Motor Company
for the most criticism. The Great Lakes Radio Consortium’s Bill Poorman
reports:
The Sierra Club ran a series of ads criticizing Ford last year. Earlier this
year, the group Bluewater Network ran a series of ads portraying Ford chief Bill
Ford as Pinocchio, for backtracking on environmental commitments he made four
years ago. The latest campaign came this summer from Global Exchange and the
Rainforest Action Network. Those ads called on Ford to develop a fleet of zero
emissions vehicles. Jennifer Krill with the Rainforest Action Network.
“Right now, Ford is the worst in the US auto industry. Ford’s average fuel
economy of its car and truck fleet is the last among the top six automakers for
the fifth straight year.”
In the U-S Environmental Protection Agency’s latest reports, Ford’s vehicles got
an average of 18-point-8 miles per gallon. For its part, Ford says some of the
environmental groups’ demands are unaffordable. The company also comes out with
gas-electric sport utility vehicle this summer.

Warmer weather might sound like a welcome reprieve to a lot of people spending early spring in the Midwest.

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.

It looks as though the Environmental Protection Agency will reject the idea of requiring cargo ships to get pollution permits before they’re allowed to discharge ballast water. The Great Lakes Radio Consortium’s Lester Graham has more:
The Environmental Protection Agency is requiring 22 states to reduceemissions that lead to smog. The states will likely go after electricpower plants that burn fossil fuels. The Great Lakes Radio Consortium’sLester Graham reports that the power companies say they’re beingtargeted unfairly and the consumer cost will be high:
