We have long
admired the work of James Hansen, the top climate scientist for NASA, and leading
advocate for environmental justice for our children.
Hansen is both a
brilliant researcher, and a devoted grandfather.
As a scientist, he measures the impacts of growing greenhouse gas
concentrations on the global climate. As a grandfather, he confronts policy-makers
with the need to take urgent action to protect those who will inherit the earth
that we leave them.
I too am a
grandfather, and I share Hansen’s passion for protecting our kids. Last summer, that passion landed us both in the
DC jail system. It seems we wore out our
welcome at the White House in an effort to publicize the global threat posed by
Canada’s tar sands, and the proposed pipeline that was to have transported it
across the U.S. heartland.

Last week, Hansen
wrote a wonderful op-ed piece in the New York Times. I hope you’ll read it for yourself, and send
it on via Facebook, Twitter or email. (Read it here.)
Hansen’s warning is stark:
“Global warming isn’t a prediction. It is happening.” And if Canada proceeds with tar sands
development, and we do nothing, “it will be game over for the climate.”
Game over? Strong
words for a scientist, right?
In a nutshell, here’s what he means. If we exploit the tar sands, and continue our
use of conventional fossil fuels as most all American politicians advocate,
then:
- CO2 concentrations in the atmosphere will reach the highest
levels in 2.5 million years;
- Sea levels will be 50 feet higher than they are right now;
- The world’s ice sheets will disintegrate;
- The world’s coastal cities (like New York, Miami, San Francisco
and LA) will virtually all be inundated;
- Global temperatures will become intolerable to humans over
much of the planet; and
- 20-50% of all living species will become extinct.
That’s right. Up to half of all species for whom we have
been appointed earth-keepers will be forever lost, says NASA’s chief scientist.
It’s Noah’s Ark in reverse. (Note: One key species under Noah's charge was mankind, lest
we forget.)
And while scientists think in the long term, the near term
is awfully sobering as well. Over just a few decades, says Hansen, while many
of today’s grandfathers still walk the earth: “the Western United States … will
develop semi-permanent drought, with rain, when it does come, occurring in
extreme events with heavy flooding. Economic losses would be incalculable. More
and more of the Midwest would be a dust bowl. California’s Central Valley could
no longer be irrigated. Food prices would rise to unprecedented levels.”
You've noticed: Hansen's list ignores the entire rest of the world. And at home, he makes no mention of Miami, New Orleans, New York and the Virginia tidewater region, just a few more near-term casualties of unbridled fossil-fuel burning.

Of course, for us grandfathers who care about our kids’
future, the oil-funded drumbeat in our presidential politics gives us
nightmares. But Hansen doesn’t give the sitting
president a pass either: “President Obama speaks of a ‘planet in peril,’ but he
does not provide the leadership needed to change the world’s course. Our
leaders must speak candidly to the public — which yearns for open, honest
discussion — explaining that our continued technological leadership and
economic well-being demand a reasoned change of our energy course. History has
shown that the American public can rise to the challenge, but leadership is
essential.”
What does NASA’s Hansen have in mind? We’ve advocated his solution for some time,
as have many thoughtful observers: “We
need to start reducing emissions significantly,” says Hansen, “not create new
ways to increase them. We should impose a gradually rising carbon fee,
collected from fossil fuel companies, then distribute 100 percent of the
collections to all Americans on a per-capita basis every month. The government
would not get a penny. This market-based approach would stimulate innovation,
jobs and economic growth, avoid enlarging government or having it pick winners
or losers. Most Americans, except the heaviest energy users, would get more
back than they paid in increased prices. Not only that, the reduction in oil
use resulting from the carbon price would be nearly six times as great as the
oil supply from the proposed pipeline from Canada, rendering the pipeline
superfluous.”
Of course, you’re not hearing this solution from virtually
anyone in politics (see exception below). Instead of making fossil fuels pay
their true costs to the world, Hansen tells of governments forcing the public
to subsidize these polluting industries with hundreds of billions of dollar per
year, and driving “a frantic stampede to extract every fossil fuel through
mountaintop removal, longwall mining, hydraulic fracturing, tar sands and tar
shale extraction, and deep ocean and Arctic drilling.”
And in the face of proclamations by the merchants of doubt
set on keeping the public paralyzed for another decade or two, Hansen leaves us
with the most prophetic of warnings: “The
science of the situation is clear — it’s time for the politics to follow…. Every
major national science academy in the world has reported that global warming is
real, caused mostly by humans, and requires urgent action. The cost of acting
goes far higher the longer we wait — we can’t wait any longer to avoid the
worst and be judged immoral by coming generations.”
Amen, grandpa. Don’t hold back. You’re speaking for my
granddaughter as well as your own.
Thanks for reading, and may God bless you.

Note: Rep. Henry Waxman (D-California) suggested
just such a carbon fee to me in his offices last month. May God bless your efforts, Rep. Waxman!
