Tens of thousands of protesters return Saturday to the streets in the Scottish city of Glasgow, host of the climate conference, and other cities around the world.

More than 200 gatherings have been planned, from Paris to Sydney, through London, Nairobi and Mexico, according to what was announced by the coalition of organizations behind this mobilization.

These moves aim to demand "climate justice" and immediate action for communities affected by climate change, particularly in the poorer countries of the South.

In Glasgow, police said they were waiting for up to 50,000 protesters not far from the high-security conference center where the COP26 climate conference has been held for the past week.

"I think it will be very important to put pressure on the world leaders assembled at COP26 and to show them that we are holding them accountable," said Iona, a 23-year-old art student who is participating for the first time in a demonstration, released by organizers.

On Friday, thousands of young people demonstrated in Glasgow at the end of the first week of the two-week "COP26" conference.

The protesters are calling on leaders to do more and work faster to confront the devastating effects of rising temperatures, caused by gas emissions from human activities.


"Failed" conference

"It is no secret that COP26 is a failure," said young Swedish activist Greta Thunberg.

She described the conference as a "celebration of chatter", after declaring commitments, some of which are unclear, by groups of countries to combat deforestation, reduce methane emissions into the atmosphere or end fossil fuels.

Meanwhile, Conference Chairman Alok Sharma said the participating negotiators should give an extra boost to the talks over the next 24 hours.

For his part, US Climate Envoy John Kerry said that developed countries will be able to provide $100 billion in climate change financing to developing countries every year, starting from 2022, a year earlier than expected.

According to the latest United Nations estimates, the world is currently heading towards a "catastrophic" temperature rise of 2.7 degrees Celsius.
