POZNAN, Poland, Dec 6 (Reuters) - About 1,000 climate protesters, some dressed as polar bears, devils or penguins, demanded on Saturday swifter action from the United Nations to combat global warming.

Outside U.N.-led talks in Poland aimed at pushing 187 countries towards stiffer targets to fight global warming, demonstrators said governments were risking the planet's future by delaying action to squabble over who was to blame.

"So far I think it's going really slowly," Susann Scherbarth from Friends of the Earth in Germany said of the talks in the western city of Poznan.

She and others protesters waved a banner reading: "Stop clowning around, get serious about climate action." Others carried pictures of seas inundating cities and villages, and the suited hand of a businessman squeezing the planet.

The march fell short of organisers' predictions of a turnout of several thousand and many inside the talks did not see it.

"It's not a matter for negotiators, it's a matter for politicians. They are the ones who have been blocking the whole process," said Rae-Kwon Chung, South Korea's climate change ambassador, adding that he was unaware of the event outside.

On Saturday marches, bicycle rides and other events were scheduled around the world to mark a "Global Day of Action on Climate", said the Global Climate Campaign, an umbrella group for participants. (Reporting by Gerard Wynn and Megan Rowling, Editing by Elizabeth Piper)
