Paris, November 29

Protesters linked hands near the violent heart of the Paris terror attacks today, giving an emotional jolt to world leaders flying into the French capital to try to save Earth from a climate catastrophe.

As hundreds of thousands of people joined worldwide protests, the human chain aimed to send a highly symbolic message to leaders on the eve of the official opening of a 195-nation UN climate summit in Paris.

French authorities cancelled two climate demonstrations following the onslaught by gunmen and suicide bombers which killed 130 people across the city on November 13.

Instead of marching, activists left thousands of pairs of shoes — weighing more than four tonnes according to organisers — on the ground at the Place de la Republique square. One pair of running shoes was left by UN Secretary General Ban Ki-Moon.

In the first organised demonstration in the French capital since the attacks, climate protesters of all ages lined the wind-blown streets to link up in a two-kilometre human chain instead of holding a march.

“I hope this time the conference will lead to something solid,” said Denis Diderot, a retired university teacher who joined the demonstration wearing a beret and a prestigious French medal, the Legion d’Honneur.

Protesters left a 100-metre gap in the chain in front of the flowers left outside the Bataclan concert hall, where the worst violence claimed 90 lives, as a mark of respect to the victims.

Some 150 leaders including US President Barack Obama, China’s Xi Jinping, India’s Narendra Modi and Russia’s Vladimir Putin will attend the official start tomorrow of the UN conference, tasked with reaching the first truly universal climate pact.

About 2,800 police and soldiers will secure the conference site, and 6,300 others will deploy in Paris, with French Interior Minister Bernard Cazeneuve saying nearly 1,000 people thought to pose security risks had been denied entry into France.

The goal of the climate talks is to limit average global warming to two degrees Celsius perhaps less, over pre-Industrial Revolution levels by curbing fossil fuel emissions blamed for climate change.

“The earth’s temperature shouldn’t rise any further and this is everyone’s concern and responsibility,” Indian Prime Minister Narendra Modi said in his monthly radio address.

Rallies demanding curbs to carbon pollution have been growing around the world since Friday, with marches involving tens of thousands across Australia today kickstarting a final day of people-powered protest.
