After 50 hours Greenpeace activists leave coal stack and head for Poznan

"For two days and nights I've sat on this smokestack and watched it accelerate climate change," said Gavin Edwards, head of Greenpeace's global climate campaign. "Nothing does more damage to the climate than coal power. The politicians negotiating at Poznan need to get serious about preventing dangerous climate change. That's why we're moving our base-camp into Poznan, to let them know the world is watching."

On 8 December, a week into the talks, the Climate Rescue Station will reopen in Poznan's Wolności Square, from where it will continue to send a message to delegates attending the climate talks to get serious about climate change, quit coal and work towards a meaningful deal to save the climate. Events will include a free "concert for the climate" by the Britten Sinfonia, open days for the public, exhibitions and debates.

At Poznan delegates must agree:

• a "climate vision" that will address what the science requires: global emissions peaking by 2015
• a draft negotiating text on the table
• a detailed workplan to get this completed by the Copenhagen meeting in December 2009
• developed countries must agree greenhouse gas emission reduction targets at the upper end of 25-40 percent, as identified by the IPCC
