Or, more hopefully:

Love life.  Don't be silly.  Be kind.

Chickens are our cousins! So are fish! So are other sentient animals! Let us learn to be kind.

work less. buy less stuff. live more.
drive less. ride a bike. every day.

Hmm, I'll have to keep thinking.  Of course, there's always the classic, that pretty much sums it all up:

"Waste not, want not."

Use less. Use it wisely. Think. Act.

Care more. Act with Compassion. Live peacefully

OR

Learn more. Act with kindness. Stop Killing

OR

Stop Killing. All Worldly Resources. Love More

Global Warming; getting real. Hard times ahead.

Gevalt!

Brilliant, David Sassoon.  But one might have thought a Sephardic Jew would have delved morally deeper.

Chickens are our cousins! So are fish! So are other sentient animals! Let us learn to be kind.

How about, along the theory that if you can't do thermodynamic calculations of heat-engine operation, or logically discusse the relative effects or lifetimes of the daughter nucleii of fission chains, you've little to contribute:

First educate yourself.  Then educate yourself.  Then educate yourself.

In this fashion..bumpersticker style...

                GREEN LIFE?
    RADIOACTIVE COAL BLACK CHEMICAL DOOM?

That'll get the advertising message across.  Then add a Hillary?Barack '08 sticker.

"Clean energy: give it away; don't tell!"

Perfect!

Chickens are our cousins! So are fish! So are other sentient animals! Let us learn to be kind.

public transit. wind solar geothermal. walkable communities.

walkable communities. wind solar geothermal. local production.

"Electrify transport. Green the grid. Energy efficiency."

Efficiency is always one of our best ways to deal with this problem, but also one of the most ignored.

If I share initials with 'Global Warming', is that a sign?

OK, 5/7/5:

rail and bicycles. wind solar geothermal. local production

but that is 3/3/2 in words, could also do

electric transport. wind solar geothermal. local production.

which is 5/7/5 and 2/3/2 word-wise, now everybody is happy?

walkable cities. wind solar geothermal. organic farming.

transit, bicycles. wind solar geothermal. save ecosystems.

Resident Troll. Misses the Point. As Usual.

Vass iz diss, "Achsan B'kteer"?  Nee fun unsern Rebbees!  Tzoo turkish!, noo?

Chickens are our cousins! So are fish! So are other sentient animals! Let us learn to be kind.

Many fools. Ignoring the Evidence. We're doomed.

Or, if you want something more hopeful:

Act now. Reduce your footprint. Live sustainably.

I was up in the wee hours last week at MIT discussing business models of clean energy.  The issue? To sell or to give away new clean energy technologies.  We settled on selling in US markets and giving in international markets.  Investors and philanthropists are both happy.  Everybody wins.

Sell local, give global, be happy

I couldn't resist.

David Sassoon, yours are the best.

Breed less.  A lot less.  Not at all.

Stop exploiting. Always act responsibly. Continue educating

personal responsibility - it'll never work! lol!

Get off your big behind and walk?

not so positive but kinda catchy?

His "haiku" is quite deep.

We have mad corporate entities wearing green facades... coroporate greenwashing.

Yes, CO2 replenishes the land, but too much is bad. Water is good for us, but submerge jabailo for a few minutes and he will become rather uncomfortable.

Finally... do not lecture the Earth... CORRECT! ... LEARN from the Earth!

Leave it to a global climate change denier to undermine his own position by trying to be a Mr. Smarty Pants.

Otherwise... good job, Mr. Bailo.

Right, GreenMom: Achshav, achshav, achshav b'Yisrael!

"Shemesh" is sure-as-tootin' "sun."  "Ruach" as "wind," though, seems to evacuate the rich religious connotations of that word.  Oh well, let us indulge the Israelis in whatever they want to do, with their electric cars, for example.

I knew somebody, David, a long time ago, here at Columbia, with roots in Halab/Aleppo, but I forget his last name (NOT Sassoon).  He was a topic of conversation in the Barnard College cafeteria, for being led around as if helplessly by a semi-Israeli lass.

Last semester, I realized a student of mine was one of the very Syrian Jews who had been written up in the New York Times Magazine, in November or so, though not himself in the Brooklyn clan -- great guy, with a lovely sense of the victimization of Hector in the Iliad.

Well hey, those Asians gotta stick together!

Chickens are our cousins! So are fish! So are other sentient animals! Let us learn to be kind.

Developed countries, don't hog the fossil fuel!

...maybe there should be a progression from the first part to the other, so

no fuels. wind solar geothermal. electric economy

no cars.  trains, bikes, buses. mostly walking

aint gotta go
no
aint gotta go
no
aint gotta go
no
jess me 'nmy dog
yeah
jess me 'nmy dog

#$%#$%#$%#$%#$%##%+_#$% : )

For the formalists: "Aint gotta go" is supposed to be three words.  "Jess me 'nmy dog" is supposed to be four words.  So do the math.

John Bailo,
we are all playing hookey.

Or, rather, even if we were in our respective schools of the belles lettres, the assignment was not to write a classic Japanese haiku, now was it.

That said, there have been some well-intentioned but plodding prosaic offerings.  Oh well, they all get A for effort.  But no contracts.

Chickens are our cousins! So are fish! So are other sentient animals! Let us learn to be kind.

"Tax carbon. Don't spend alot."

"Use less juice. Burn less stuff. Use the sun."

"Eat puppies. Roasted with garlic demiglaze" (OK, made that one up)

One Earth.
Live green now.
Or we die.  

Live smarter. Healthier too. No Birkenstocks required.

Or were you trying to make a point?

By the way, the Modern Language Association will be all over you for apparently equating "our economy" with "human civilization."  So you had better get your press releases ready.

   Lots of great slogans!!!  Why limit ourselves to one!!  Use them all!!

is that these are starting to drift away from the initial challenge -- communicating about global warming -- and toward extremely general environmental slogans.

It is communicating about climate change in particular that is so difficult.

don't emit. you must commit. just do it.

the economy. wholly owned subsidiary. of environment

the greenest product is none at all

How about:

"Eat plants. Don't drive much. Tax soot."

or

"Consume consume. Consume consume consume. Consume consume."

Relax more. Live for tomorrow. Worry less.

Chill out. Step up. Save the Planet.

Attempts #5 and 6 are superb.

John Bailo,
you are getting it!!  That "queer old balloon man" bit is really fine!

Chickens are our cousins! So are fish! So are other sentient animals! Let us learn to be kind.

so little action.

So few make so much

wealth by doing so little

that can be judged good.

.........sharing naught.

Clean Energy.  Green Jobs.  One Planet.

No new coal.  Stop the madness.

Greenmom.

Clean Energy.  Green Jobs.  One Living Planet.

That's the bumpersticker.  That's a winner.

Eat greens. Ride a bike. Waste not.

Greenmom, on the NRDC blog.  Do we get a cut of the bumpersticker loot?  

Nope, it'll all go to lobby against Cape Wind and for "clean" coal, nukes, and fuel farming.  After all, it IS NRDC.

I think the following is the strongest:

You're either with us or against us

I can't claim it as my own: I just saw it as a bumper sticker and thought it spoke elegantly and eloquently to the two big issues: quality of life and overpopulation.

And as a bonus, it's guaranteed to piss some people off!

The true meaning of life is to plant trees, under whose shade you do not expect to sit.

Climate Challenge. Our Greatest Opportunity. Seize It.

Pretty vanilla slogan, if you ask me.  And the honorable mention?  What does religion and respect/love for fellow man have to do with climate change? (Yes, of course, everything is interconnected when we are talking about the Earth, but really, a bit of a stretch to "communicate what people need to know about global warming," no?)
