Activists around the world have participated in "Rise for Climate" protests before the San Francisco summit taking place this week.

More than 18,000 people have marched in Paris as part of an international mobilisation to show popular support for urgent measures to combat climate change in advance of a San Francisco summit.

Crowds overflowed a plaza in front of City Hall before marching east to the Place de la Republique, carrying an urgent message that it's up to the public to put global warming at the top of the political agenda.

"Planet in Danger," read some banners on Saturday.

Activists around the world encouraged "Rise for Climate" protests before the summit taking place on Wednesday to Friday. California's governor proposed the event after President Donald Trump vowed to pull the US out of a landmark 2015 climate accord.

The international agreement was negotiated in France, and the French capital's march was more successful than ones held on Saturday in other French cities or elsewhere in Europe.

Environmental groups said they organised hundreds of events around the globe Saturday to highlight the issue.

Thousands of people took to the streets of San Francisco, marching from the city's piers to City Hall. Demonstrators banged drums, sang and hoisted signs that said "Rise for climate justice" and "Not a penny more for dirty energy." They called for politicians to spearhead a transition to 100 per cent renewable energy.

Police estimated that 18,500 took part in the Paris march, while organisers put the number at some 50,000.

Several hundred people gathered in France's southern port city of Marseille. Several dozen called for an end to the use of fossil fuels outside London's Tate Modern art gallery. Only about two dozen showed up in Barcelona, Spain.
