The Global Climate Marches have commenced with over 60,000 people marching for action in Melbourne today – the largest climate event of its kind ever held in Australia. Over the weekend, hundreds of thousands of others around the world will take to the streets in more than 2,300 events in 150 countries – to turn up the heat on leaders heading to the Paris Climate Summit on Monday. Frontline community representatives, unionists, faith leaders, NGOs, families and celebrities will call on governments to forge an ambitious new global climate agreement this December that speeds up the just transition from fossil fuels to 100 per cent renewable energy and protects vulnerable people from worsening climate impacts. The UN climate talks come on the heels of the Commonwealth Heads of Government meeting in Malta, a gathering where member nations are traditionally expected to address threats to the world’s poorest and most vulnerable populations, and – in this case – to produce some additional momentum for a Paris outcome that successfully tackles the biggest of these threats: climate change. As world leaders move from the first set of meetings towards the next to collectively address the climate crisis, they will be expected to outline a sustainable model to run our societies that delivers on climate stability, clean energy solutions and poverty alleviation. After a year that has seen unprecedented momentum and public support for climate action, with most nations launching national climate action plans to tap into the multiple benefits of joining the clean energy transformation, Paris is now expected to deliver the first truly universal climate agreement that gives the world a fighting chance to keep global warming below the internationally agreed 2DegC limit. The tasks for governments over the next two weeks are clear: build on the strong momentum and use the clear public mandate for action to craft an agreement that includes a long-term goal to decarbonize the economy over the coming decades, an ambition mechanism that strengthens national targets every five years, the $100 billion per year in climate finance pledged towards decarbonization and climate resilience in developing countries, as well as an adaptation goal and a loss and damage mechanism to address irreversible and permanent climate change impacts.
