Swedish climate activist Greta Thunberg gives a speech during the COP25 UN Climate Change Conference in Madrid with Greenpeace International executive director Jennifer Morgan, and Spanish environment minister Teresa Ribera in the background
Madrid (AFP) - Swedish activist Greta Thunberg accused rich countries of "misleading" people over climate action at UN talks in Madrid on Wednesday hours before a veteran leader of the global environmental movement with whom she shared the podium was locked out of the conference.
The UN climate forum tasked with saving the world from runaway global warming has become an "opportunity for countries to negotiate loopholes and avoid raising their ambition" to act on climate, the 16-year-old told delegates and observers to vigorous applause.
"Countries are finding clever ways around having to take real action."
Nations gathered in Spain's capital are struggling to finalise the rulebook of the 2015 landmark Paris climate accord, which aims to limit global temperature rises to "well below" two degrees Celsius and to a safer cap of 1.5C if possible.
But the consensus-based talks are bogged down in politically charged wrangling over the architecture of carbon markets, timetables for the review of carbon-cutting pledges and a new fund to help poor countries already reeling from climate impacts.
Amid glacial progress in negotiations, more than 200 youth and indigenous rights activists were forcibly removed after protesting outside the plenary hall, chanting "climate justice now!" and "Shame! Shame! Shame!".
Among those unable to access the talks was Greenpeace International executive director Jennifer Morgan, who had joined Thunberg in addressing plenary delegates hours earlier.
All accredited observers -- researchers, scientists, NGOs who play a critical role in the talks -- not already in the building were also denied entry after the fracas.
- 'This is not leadership' -
"We are the ones who can apply pressure and hold governments accountable," Morgan told AFP outside the COP25 venue.
"I call on the Secretary General to intervene here to make sure that youth and citizens around the world can engage and have their voices heard in these negotiations."
Several sticking points remain as the two-week marathon negotiations enter the final days.
Nations are at odds over how the fight against climate change should be funded and how carbon trading schemes should be regulated.
In addition, there has been little progress over the issue of "loss and damage" -- how countries already dealing with the worst impacts of climate-related extreme weather and drought should be compensated.
The UN's top climate body the IPCC says that the safest way to stay under the 1.5C cap is a rapid and sweeping drawdown in the coal, oil and gas driving greenhouse gas emissions.
"The red thread in science over the past 20 years, is that we have underestimated the pace of change and the risks we are facing," Johan Rockstrom, director of the Potsdam Institute for Climate Impact Research, told the plenary.
The temperature tipping point for catastrophic and irreversible changes in Earth's climate system -- once thought to be 5C or 6C -- is now understood to be between 2C and 3C, he said.
Thunberg, who was awarded Time magazine's person of 2019 on Wednesday for her environmental campaigning, told negotiators that their promises were a world apart from what was needed.
- 'At the highest level ' -
"Recently a handful of rich countries pledged to reduce their emission of greenhouse gases by so and so many percent by this or that date, or to become climate neutral or net zero in so and so many years," she said.
"This may sound impressive at first glance, but even though the intentions may be good this is not leadership. This is not leading, this is misleading."
Despite dozens of meetings and thousands of specialists working to implement the Paris accord, global emissions continue to rise each year.
Laurence Tubiana, architect of the Paris deal and current head of the European Climate Foundation, said there was slim prospect of major progress in Madrid.
The key issue of how ambitious countries' climate plans can be would only be settled at next year's COP26 summit in Glasgow, she told AFP.
"This decision needs political negotiations at the highest level -- Xi Jinping will decide for China, Modi for India, it will be like that for all countries."
One leader who will almost certainly not join the negotiations but may still influence the outcome is Donald Trump. The US president set in motion the US withdrawal from the 2015 climate treaty last month.
"Our last day as a Party to the Paris Agreement will be November 4, 2020," Marcia Bernicat, a career State Department diplomat and head of the US delegation, told fellow delegates late Wednesday.
"We remain fully committed to working with you, our global partners, to enhance resilience, mitigate the impacts of climate change, and prepare for and respond to natural disasters."
