World leaders including UN Secretary-General聽Ban Ki-moon聽were set to join farmers, fishermen, children, and others in a massive demonstration on Sunday to demand action on聽climate聽change.

Organizers are expecting 100,000 to join the People's聽Climate聽March聽in midtown Manhattan ahead of this week's U.N. General Assembly, which brings together 120 world leaders to discuss reducing carbon emissions that threaten the environment.

The New York rally was expected to be the largest on a day of events in 161 countries including the聽United Kingdom, France, Afghanistan, and聽Bulgaria.

The gathering will include celebrities such as musician聽Sting, scientists in lab coats, labor groups, 20 marching bands, and floats powered by biodiesel vehicles or pulled by hand, said聽Jamie Henn, spokesman for 350.org, which organized the event with more than a dozen other environmental, labor, and social justice groups.

"You can't fight聽climate聽change sitting on your couch and holding your breath," Henn said.

Organizers said the massive mobilization is aimed at transforming聽climate聽change "from an environmental concern to an everybody issue.'"

The聽United Nations聽on Tuesday is set to host a聽climate聽summit where world leaders will continue talks toward a pact 200 nations are working on that would rein in the rising greenhouse gas emissions. Negotiators aim to complete that deal in late 2015.

In聽London, actress聽Emma Thompson聽and fashion designer聽Vivienne Westwood聽were among celebrities who took part in a聽march聽of thousands of people who processed through central聽London聽towards a rally by parliament.

"Politicians are not showing the will. There is not a problem with the science, there is a problem with the political will," said聽Ben Phillips, campaigns director for聽Oxfam. "That is why it is so important that people are marching here today."

New York City Mayor聽Bill de Blasio, who is expected to join the marchers, on Sunday unveiled a new plan for the city to reduce its greenhouse gas emissions by 80 percent from 2005 levels by 2050.

All 3,000 city-owned buildings that use significant amounts of energy would be retrofitted with energy saving heating, cooling and light systems by then, he said, though meeting the commitment will also require significant investments by private landlords.

"Climate聽change is an existential threat to New Yorkers and our planet. Acting now is nothing short of a moral imperative," de Blasio said.

The 2-mile (3.2-km) route sanctioned by the New York Police Department winds pastTimes Square, where dozens of giant billboards聽flash聽even at midday and attempts at eco-friendly signs - lit by wind power - have been spotty.

Organizers bill the event as the largest gathering focused on聽climate聽change since 2009, when tens of thousands of people gathered in聽Copenhagen聽in a sometime raucous demonstration that resulted in the detention of 2,000 protesters.

鈥淥wn a trumpet? Bring it. Own a vuvuzela? Definitely bring it,鈥� said Bill McKibben, co-founder of聽, a Brooklyn-based activist organization against climate change, which helped organize the march. 鈥淲histles, drums, tin cans, vocal cords 鈥� we're going to make a noise that will echo down over the eons.鈥�
