The Price of Global Warming

There’s evidence that the Earth is changing
because of global warming. Glaciers are receding.
Polar ice caps are melting. Weather patterns are
altered. That’s prompted some people to look
for ways to reduce their personal contribution to
global warming. Rebecca Williams reports there
are many new companies that claim to help you do
that… for a price:


Whenever you drive, fly, or ride, you’re emitting carbon dioxide. And it’s not just the way you get around. It’s also any time you turn on lights or plug into an electrical outlet. More than half of the electricity in the U.S. comes from power plants that burn
coal and that’s another major source of carbon dioxide.


It’s a problem because carbon dioxide is a potent greenhouse gas.
The vast majority of scientists agree all this carbon dioxide
that people produce is trapping heat in the atmosphere and making
the planet warmer.


David Archer is a climate scientist at the University of Chicago:


“The problem with fossil fuels is that the cost of that climate
change isn’t paid by the person who makes the decision to use
fossil energy so it’s sort of like a bill we’re leaving to future
generations.”


Some people say there’s a way to pay that bill now. About three
dozen companies and nonprofits have sprung up in the past few
years. They’re selling carbon offsets.


The idea of a carbon offset is to balance out the carbon dioxide
that you emit. In theory, you can do this by investing in
something like tree planting or energy projects that don’t emit
greenhouse gasses, such as wind or solar power.


First, you can go to one of the group’s websites and calculate
your carbon footprint. That’s all the carbon dioxide you produce
by driving, flying, and so on, in a year. North Americans have
especially big footprints.


The companies assign a price per ton of carbon that’s emitted.
You can decide how much of your carbon-emitting you want to
balance out. Then you type in your credit card number and voila… no more guilt.


Well, that’s the idea anyway.


But what if you buy a carbon offset
but you don’t change your behavior? If you keep driving and
flying and using electricity just as much as before, or maybe
more than before, you’re still a part of the problem.


“You’re absolutely still emitting the carbon. The idea is that
you’re balancing it out through reductions elsewhere.”


Tom Arnold is a cofounder of Terrapass. It’s a carbon offset
company:


“Now this isn’t the optimal solution of course – you should stop
driving. But it’s a good way that we can get you involved in the
dialogue and help you reduce emissions somewhere else.”


And you can get a little sticker for your car to show you’re in
the offsetting club. But Tom Arnold admits there aren’t a whole
lot of drivers of huge SUVs buying offsets.


“We have this nice little SUV sticker – it’s pretty expensive and
a horrible seller. Most of our members already drive passenger
cars, very efficient cars. They’re just looking for a tool to
balance the rest of their impact out to zero.”


Erasing your carbon footprint sounds pretty positive, but there
are quite a few critics of the carbon offset industry. They
point out there aren’t any agreed-on standards for what an offset
is, and prices are all over the map. So it’s not always clear
what you’re getting for your money.


Mark Trexler is president of Trexler Climate and Energy Services.
He’s a consultant who reviews the groups selling carbon offsets.
He says you do have to ask questions about what you’re buying:


“Am I putting my money into something that wouldn’t have happened
anyway? Because if somebody would’ve built that windmill anyway
or if they would’ve done whatever it is you’re putting money into
anyway, you’re really not rendering yourself climate neutral.”


Trexler says there are certification programs in the works so
consumers can know more about what they’re buying. But the people
who are buying offsets now say it feels like they’re making a
difference.


Kate Madigan bought offsets. She started thinking about it when
she was awake at night worrying about the world her new baby
would live in:


“Some people say oh, global warming, it’s going to change the
world in 100 years, but I’ll be gone by then. But I think that’s
a horrible way to look at things because we’re leaving the world
to a lot of people that we love.”


Madigan says she doesn’t think carbon offsets alone will really
solve the problem. She says she thinks it’ll take a lot of
harder choices too, like driving less and using less electricity.


Supporters say that’s the real power of offsets. It’s getting
people to talk about the role they play in global warming.

Several Midwest universities will be part of a controversial effort to
improve the recycling of nuclear waste. The Great Lakes Radio Consortium’s
Chuck Quirmbach reports:


Spent nuclear fuel is piling up at many commercial nuclear power plants around the nation.
Scientists know how to re-process and re-use the fuel. but that’s currently not done
in the U.S. nuclear industry.


Michael Corradini is an Engineering Physics Professor at the University of Wisconsin-Madison.
He says the re-use of nuclear waste can be improved… and he contends this is the moment to do
it.


“And with the need for energy… particularly electrical energy… this is a way to more efficiently
deal with our spent fuel.”


Wisconsin and other Big Ten universities with nuclear engineering programs will team up with
the University of Chicago for a recycling project at the Argonne National Lab in Illinois. But an
anti-nuclear group contends that trying to recycle more nuclear waste makes it more likely some
spent fuel will be made into bombs. The university scientists say safeguards will be taken to
prevent that from happening.
