Stripping down from 390ppm to 350ppm – that’s the target of 350.org as portrayed in last Saturday’s international day of climate change. Check out this hot video!……………

Activists held events around the world yesterday to mark the number they say the world needs to reach to prevent disastrous climate change: 350.

The number represents 350 parts per million of carbon dioxide emissions in the atmosphere that some scientists say is the safe upper limit. The atmosphere currently reaches about 390 parts per million, according to research by NASA climate scientist James Hanse cited by 350.org.

Hundreds of events highlighted the number in different ways.

In what 350.org founder Bill McKibben called a global game of Scrabble, groups in Australia, Ecuador, India, the United Kingdom, the U.S. and Denmark each spelled out one of the numbers in 350. Hundreds gathered in New York City’s Times Square and watched slideshows of the other events on giant screens.

McKibben, an environmentalist and author of “The End of Nature,” said the day was unique because it emphasized the science behind a politically complicated topic.

“It was ordinary people rallying around a scientific data point,” McKibben said. “Nothing like that has ever happened before.”

For 20 years the world has managed to do very little about the greatest problem it’s ever faced. In three days time, you can help change that–and if you step up you’re going to have a lot of company!

It looks like the International Day of Climate Action this Saturday October 24th will be the single most widespread day of political action the planet has ever seen–we’re closing in on 170 nations, and more than 4000 rallies and events.

There will be climate events from the bottom of the Great Barrier Reef to the summit of Mount Everest.  At each event — at rallies and parties and deep-sea dives — people will take a big photo that somehow depicts the number 350.  Our crew at 350.org will be taking these thousands of photos, projecting them on the giant screens in New York’s Times Square, and delivering them directly to hundreds of world leaders and politicians in the coming weeks.

There’s almost certainly an event happening near you–if you’re not sure what, this link will let you find out quickly and easily:

Superheroes indeed! I found them all over South Africa, from Witwatersrand University in Johannesburg to the botanical gardens of Cape Town. This is a country, obviously, that knows a little bit about political movements, so it’s not entirely surprising that people are coming up with dramatic and creative actions: a mass climb of the iconic Table Mountain that juts out above the confluence of the Indian and Atlantic Oceans in Capetown, or simultaneous bike rides in the three main cities, or — the list is long.

I ate breakfast with bishops and other clerics; lunch with biologists; dinner with journalists. South Africa is incredibly diverse and beautiful, which means it will suffer from all the various forms of trouble that climate change brings — drought on the desert edges that now support agriculture, for instance. And because it’s a developing country with an enormous first-world population, it has a real mix of causes and consequences. But more to the point, there seems to be a surplus of people ready to go to work, on Oct. 24 and in the months thereafter. This place has worked miracles before — and everyone we talked to pointed out that it the international movement against apartheid helped pressure the country to change. That’s the kind of pressure we need now!
