Activists seek tough UN climate pact in 100 days

Environmental organisations, trade unions, religious groups, scientists, anti-poverty campaigners and others representing tens of millions of people teamed up to put pressure for curbs on greenhouse gas emissions.

"Time is running out," said Kumi Naidoo, chair of the Global Campaign for Climate Action of the "TckTckTck" campaign, meant to refer to the sound of a clock ticking as the U.N. meeting draws closer.

TckTckTck would include actions such as rallies or online advertisements to show, for instance, how people in developing nations are already suffering from global warming and how a shift to green jobs could help recovery from recession.

Friday is exactly 100 days from the Dec. 7 start of the two-week meeting in Denmark due to agree a successor to the U.N.'s Kyoto Protocol to rein in changes such as more droughts, floods, rising sea levels, a spread of disease and heatwaves.
