Very big, in fact. This campaign has gone viral--there will be over four thousand events taking place simultaneously in over 175 nations. As far as we can tell, you'll be part of the single most widespread day of political action about any issue that our planet has ever seen.

There are too many incredible events to list in one place, but here are some of the highlights:

a.. In Cambodia, citizens from across the country will gather at the famous Angkor Wat to take a giant 350 action photo.

b.. In Hungary, hundreds of bathers will jump into the public baths in Budapest and do a 350 synchronized swimming performance.

c.. In Nepal, over a thousand young people and monks will march to the Swayambhunath world heritage site temple where they will form a large 350 with traditional lanterns.

d.. In the United States, 350 people will dance to Michael Jackson's Thriller in Seattle -- because if we don't stop global warming, we might as well be undead.

e.. In Panama, indigenous youth will lead a moonlight vigil in Kuna Yala, their vulnerable low-lying islands off the coast of Panama, forming a 350 at sunrise.

When you're out there marching or rallying, biking or kite-flying, singing or taking part in whatever is going on in your community, take a minute and try to imagine all the other people doing the same kind of things all around the world--every one taking the same basic scientific fact and driving it into the public consciousness.

350 is the most important number in the world--scientists have told us that it's the most carbon dioxide we can have in the atmosphere, and now we're making sure everyone knows. We'll be taking photos from all the events, projecting them on the big screens in New York's Times Square, and delivering them to major media outlets and hundreds of world leaders in the coming weeks. The combined noise from these events will ensure that world leaders who gather next month at the UN climate talks in Copenhagen to create the world's new plan on climate change will hear our call. They will know that when negotiating the fate of our planet, there is a passionate movement out there which will hold them accountable.

After your event on Saturday, check out www.350.org, where we will show a glorious slideshow of photos from events in every corner of the earth. Be proud of what you've accomplished.

Onwards,

350.org is an international grassroots campaign that aims to mobilize a global climate movement united by a common call to action. By spreading an understanding of the science and a shared vision for a fair policy, we will ensure that the world creates bold and equitable solutions to the climate crisis. 350.org is an independent and not-for-profit project.

What is 350? 350 is the number that leading scientists say is the safe upper limit for carbon dioxide in our atmosphere. Scientists measure carbon dioxide in "parts per million" (ppm), so 350ppm is the number humanity needs to get below as soon as possible to avoid runaway climate change. To get there, we need a different kind of PPM-a "people powered movement" that is made of people like you in every corner of the planet.

In London

The key action in the 350 (http:/www.350.org) campaign in London is a giant aerial photo in front of the London Eye, highlighting the critical 350 number. It begins at 2pm. Here is the press release:  http://www.london350.org/5for350.pdf

It's a real opportunity to frame the climate change negotiations in Copenhagen, and raise awareness on this issue.

The Big Blow (AKA Global Horning)

Horn players, or blowers generally, read on, and clear your lungs for tomorrow...

What: THE BIG BLOW (AKA Global Horning). It's one of the 4000 amazing actions taking place for 350 day ( http://www.350.org/)

When: Saturday October 24th, 12.30pm

Where: London Victoria Tower Gardens. Closest stations Westminster or Pimlico.Please see attached map

Why: We need to make some noise about climate change. What better way to do that than with the collective wind power of hundreds of brass players?

Who: You! and your friends. Minimal skill required, just a bee in your bonnet and a horn in your hand.

We will be playing the note F (350Hz in keeping with the 350 theme) so as long as you can do that, we need you!

It's not just brass,players, didgeridoo players, bag pipes, kazoos, penny whistles, recorders, anything you need to blow to play really... All welcome!

We need to do this now. 350 parts per million is the amount of carbon dioxide the earth's atmosphere can handle without catastrophic climate change. Sadly, we're already at 390ppm so when global leaders meet this December in Copenhagen to negotiate the agreement that will replace Kyoto, we need to make sure they meet the goal of getting us back to 350. That's why the organisation  http://www.350.org/, has organized an international day of climate action six weeks before the Copenhagen meetings. We will have a photographer there so that our image will one of the thousands of images to be screened in Time Square, handed to governments, diplomats and delegates.

The message will be loud and clear, and we will be a part of it!
