Don’t let your seemingly vast experience as an inhabitant of this world fool you. It’s easy to be lulled into a false sense of self-importance. Let me explain.
You likely live in a house or apartment on a street, and in a community that’s part of some town, maybe even some major urban area. Your community is likely part of a much larger state or province of one of the nations of Earth—which are themselves nothing more than imaginary constructs of human society. Your country is also likely assigned to one of the continental masses whose sum total of land area is just 29% of the planet’s surface. You are small and the Earth is seemingly vast, as if we humans to Earth are just so many micro-organisms scurrying about each day (each rotation of Earth), and following rules of social engagement that often defy logic.
It’s a story that at a most fundamental level defines your address. It may be all the address you need to ship a package to your friend across the ocean. But it won’t cut it with the intergalactic post office. As I said, don’t let your experience and perception fool you. It’s the rest of the address of which most Earthlings are unaware. For so many reasons it’s also the most important part of the address.

I had a day of meetings yesterday, with no connection to the outside world. When I got home a good friend stopped over and asked if I heard what Al Gore had said in Copenhagen, and the firestorm it created in the world media. I had not. So I made a beeline for the computer and sought out the circus-sphere passing for journalism these days. Here is what I found.
A Timesonline story titled “Inconvenient truth for Al Gore as his north pole sums don’t add up”, may have been the focal point. Apparently Mr. Gore said, as reported by the Timesonline—
A Doctor Jeff Myth Buster: Carbon Dioxide is Just a Trace Gas – BIG DEAL!

Here’s how the argument goes—and do it justice by reading it out loud, and kinda yelling whenever you see words in CAPS.
“Hey, you’re worried about CO2 concentration in the atmosphere going up because of human activity and causing an increase in global temperature?! GIVE ME A BREAK! It’s only a TRACE gas, currently making up only 0.038% of the atmosphere, or 380 parts per MILLION!! SO WHAT if we increase it to a WHOPPING 1,000 parts per million (ppm) by 2100. Then it would ONLY comprise 0.1% of the atmosphere. BIG DEAL!! There is NO CONCEIVABLE WAY that changes in such a miniscule amount of CO2 could have any significant impact on the global environment. You’re preaching the sky is falling, and ANYONE WITH HALF A BRAIN can see that this is just SILLY! YOU must be part of some Scientists-in-Need-of-Federal-Funds—Green Business—Government (SiNoFF-GB-G) conspiracy that’s bent on destroying everything that is good. TAKE A WALK YOU ENVIRONMENTAL ACTIVIST IN NEED OF A CAUSE. Why … you’re likely a paid operative of the SINoFF-GB-G machine!”
Ummm.. has anybody else heard this argument, or is it just me? Here’s my rebuttal (and you’re still using the CAPS-means-shouting thing.)

It’s a new school year, and I couldn’t wait to get back into the routine of my morning drive with Jordi. I missed our daily conversations about Earth, space and everything else in his known universe while we navigate the fabled Washington, DC, Beltway to his school. Sure, we spent lots of great family time together over the summer at the pool club, and in New York. But there was something magical about taking 30 minutes of dull driving each morning and turning it into a free-for-all ‘Jordi where do you want to take the conversation today?’
To help you picture it, I’m always driving with my cup of coffee, glancing in the rear view mirror—waiting. He’s usually staring forward, transfixed. You’d almost think that my now 7-year-old is just zoning—except that he’s got that slight squint which tells me wheels are turning furiously inside. Then BOOM! He launches our great morning adventure with a simple, elegant, deep thought.
So last week, like always, just out of the blue—
“Daddy, how many Empire State Buildings tall is the tallest mountain?”
Today he wanted daddy to help him conceptualize the height of a really tall mountain. He wanted to use a familiar ruler.

This is a Teachable Moments in the News QuickLinks Post. It connects a news story with this Blog’s existing powerful library of Posts and Resource Pages. The cited Posts and Pages provide a deep understanding of concepts in the earth and space sciences relevant to the news story. Teachers—the Posts and Pages are also designed for use as lessons, allowing you to easily bring current science into the classroom as a teachable moment. Each cited Post is outlined in the Teachers Lesson Planner, which includes the Post’s essential questions, concepts, objectives, and math skills.
Earth Science Week takes on a rather unique importance in 2009. This year’s theme is Understanding Climate. On December 7-18. 2009, the entire world will meet in Copenhagen for the United Nations Climate Change Conference, to hammer out the next international agreement on climate change and put in place new targets for greenhouse gas emissions. It may be humanity’s last opportunity to craft an agreement—AND get it ratified by the world’s nations—before the Kyoto Protocol of 1997 (and in force in 2005) expires in 2012. This seems to me to be a very big deal for the future of this planet, particularly in light of the latest projections for the impact of global warming—which indicate we need to act NOW or face irreversible consequences (see CNN, March 12, 2009)—and Copenhagen is the venue for that action.
The United Nations Intergovernmental Panel on Climate Change (IPCC) has now issued 4 Reports, the last issued February 2, 2007:
On Feb. 2, 2007, the United Nations scientific panel studying climate change declared that the evidence of a warming trend is “unequivocal,” and that human activity has “very likely” been the driving force in that change over the last 50 years.
—New York Times, October 11, 2009
If we allow things to continue unchanged and we don’t take action today, it would destabilize human society.
—Rajendra Pachaurihead, Head of the UN Intergovernmental Panel on Climate Change (IPCC), “Climate chief warns against ‘Tragic’ inaction”, CNN, August 21, 2008
Here are some relevant links:

Assessment by U.S. Department of Defense on U.S. National Security, and on the grave scenarios that can play out from global warming: New York Times (August 8, 2009)
My point is that over the next few months, the world faces a unique and seminally important moment in time, and Earth Science Week 2009 should serve as a timely catalyst for education in the US. HERE is the countdown clock to Copenhagen.
To date I’ve created 5 Posts at Blog on the Universe—5 powerful lessons—on climate change and global warming that I’d like to share with you as resources to use in classrooms and in discussions at home this coming week.
First, what is Earth Science Week?

This post is a Dr. Jeff’s Weekly Challenge. It was requested by (teacher extraordinaire) Jami Lupold and her class in the great city of Houston, Texas, USA.
If you’re a teacher and your class has an idea for a blog post, slip me a note!
Last week I gave you a scare. It happened when I told you that you’re really on a spaceship hurtling through space. I was in the midst of describing all of Earth’s motions—it spins, it orbits the Sun, the Sun orbits the center of our galaxy carrying Earth and the Solar System along for the ride—and that’s when I saw panic on your face. You started to get a bit dizzy, so I turned on the “fasten seat belt sign” in light of all the conceptual turbulence ahead. To keep your mind off all the spinnin’ and revolvin’ I gave you an assignment to calculate Earth’s speed—your speed—due to these three motions. Does this all ring a bell? No? Why don’t you go and re-read the original challenge from last week, so you can refocus.
Good. Now that you’re back. Let’s get to the answers. Did I mention this week’s challenge was in our in-flight magazine in the seat pocket in front of you? By the way, I see you dug your fingernails into your seat, and your fingertips seem a bit blue. (Hope the answers don’t send you into a panic.)

You wanted to be an astronaut? Poof. Done.
You and your friends are on a spaceship called Earth—with all known life aboard. With you sitting there calmly reading this, and no obvious need to hold on to something for dear life, it might seem that the spaceship under your feet is carrying you on a nice steady trajectory through space. Uh … Nope. Right now you’re being carried along on something more akin to a cosmic-sized amusement park ride. Earth is rotating on its axis, it’s orbiting the Sun, and the whole Solar System (the Sun and its planets, dwarf planets, asteroids, comets, and Trans-Neptunian Objects) is orbiting the center of the Milky Way galaxy. The Milky Way itself is moving relative to other nearby galaxies, the local group of galaxies is moving through a greater space, and all this is set against a backdrop of an expanding fabric of space and time across the entire universe. I know!!!! (© Craig Ferguson) Dizzy?
[Pleasant Ding] The captain has just turned on the seat belt sign. There may be some conceptual turbulence up ahead. But I’ll make the ride as smooth as possible.
OK, I think a Weekly Challenge requesting that you calculate all the spinning, and revolving, and free-flying is a bit much, so let’s concentrate on three things:

On a recent tour of CBS, I got separated from my group, got pretty lost, and ended up in a dusty storage room filled with nightmarish props that really creeped me out. In the corner I found an old envelope marked “Rod Serling’ with a script inside. Wow. I decided to turn it into a BotU Weekly Challenge and introduce a new character kinda like, well, me. (It is my Blog.)
First a word from our Sponsor—
Come back Monday, August 24. for the solution to this Weekly Challenge.
Come back Friday, August 21, for a new post “The Scale of the Solar System—A Voyage in Corpus Christi”
Submitted for your consideration, I invite you to accompany me to a Cosmic Kitchen where each entree is of galactic proportions, and ingredients are folded together with forces both unimaginable and seemingly limitless. As we enter the infinite spaces allocated for baking, a solar-system-sized pasta press has just been loaded with planet Earth, and an ejector plate has been inserted which has but a single hole in the center with an adjustable diameter. Chef Jeff has closed the massive door behind the planet, and now the only way out for Earth is through that small opening—for today’s special in the Cosmic Kitchen is Earth spaghetti.

Nice to see you again! Now that you’re back from your interplanetary romp through the Solar System, let’s see those cool photographs you took for the Dr. Jeff’s Interplanetary Travel Agency tour brochure.
[Hmmm .... silence.] You there?? Earth to my contracted photographer, you seem to be processing all this a bit slowly. I suspect you’re suffering from ‘rocket lag’. It’s perfectly understandable after traveling over 10 billion miles and visiting 7 worlds. I don’t think any photographer has ever been this dedicated. You’re clearly worth more than I’m paying you. So take a load off, and first re-read Weekly Challenge 5 to get back up to speed.
