UNITED NATIONS — This is the world we live in: Punishing heat waves, catastrophic floods, huge fires and climate conditions so uncertain that children took to the streets en masse in global protests to demand action.
But this is also the world we live in: A pantheon of world leaders who have deep ties to the industries that are the biggest sources of planet-warming emissions, are hostile to protests or use climate science denial to score political points.
On Monday, at the United Nations Climate Action Summit, comes a glimpse of how far presidents and prime ministers are willing to go. U.N. Secretary-General António Guterres expects around 60 countries to announce what he called new “concrete” plans to reduce emissions and help the world’s most vulnerable cope with the fallout from global warming.
The problem is, the protesters in the streets and some of the diplomats in the General Assembly hall are living in separate worlds.
“Our political climate is not friendly to this discussion at this moment,” said Alice Hill, who specializes in climate policy at the Council on Foreign Relations. “Multilateralism is under attack. We have seen the rise of authoritarian governments.
“We see these pressures as working against us,” she said. “We don’t have leadership in the United States to help guide the process.”
President Donald Trump, in fact, has rolled back dozens of environmental regulations, most recently reversing rules on auto emissions, saying that they were an unnecessary burden on the U.S. economy. In Brazil, Jair Bolsonaro wants to open the Amazon to new commercial activity. In Russia, Vladimir Putin presides over a vast, powerful petro-state. China’s state-owned companies are pushing for coal projects at home and abroad, even as the country tries in other ways to tamp down emissions. Narendra Modi of India is set on expanding coal too, even as he champions solar power.
The latest report by a U.N.-backed scientific panel, meanwhile, projected that if emissions continue to rise at their current pace, by 2040, the world could face inundated coastlines, intensifying droughts and food insecurity. Basically, a catastrophe.
At a press briefing before the Monday summit, Guterres was bullish on what he described as a new willingness by governments and companies to address climate change seriously. He said he hoped “a very meaningful number of countries” would declare their aim to reduce carbon emissions significantly and aim to be carbon-neutral by 2050.
“All of a sudden I started to feel there was momentum that was gaining, and this was largely due to the youth movement that started a fantastic, very dynamic impulse around the world,” Guterres said Saturday as a UN Youth Climate Summit began.
There will be some important no-shows at the Monday meeting, though. The United States, the largest economy in the world, has not even asked to take the podium. Nor has Brazil, home to most of the Amazon rainforest, often referred to as the lungs of the planet. Nor Japan, an economic powerhouse and the world’s seventh largest emitter of greenhouse gases.
So, Guterres also tempered expectations. He told reporters at a briefing Friday that he did not expect announcements at the summit to yield emissions reductions that would measurably keep temperatures from rising to dangerous levels. At the current pace, global temperatures are set to rise beyond 3 degrees Celsius from preindustrial levels by the end of the century even if every country on Earth meets its goals under the 2015 Paris pact, which calls on nearly 200 nations to set voluntarily targets to reduce their emissions. Many big countries, including the United States, are not on track to meet their commitments.
Organizers estimated the turnout at the Friday protests to be around 4 million across thousands of cities and towns worldwide. Never has the modern world witnessed a climate protest so large and wide, spanning societies rich and poor, tied together by a sense of rage. “Climate emergency now,” read banners in several countries.
Whether youth protests can goad many world leaders into changing their policies is a big question mark at best, said Michael Gerrard, a law professor at Columbia University. Some of them are closely linked to fossil fuel and extractive industries, he noted. Others have a record of crushing protests. And so the outcry, Gerrard said, may well fall on “intentionally closed ears.”
Still, the protesters and the diplomats have radically different expectations, and even a different sense of time.
On Saturday, at the youth summit, Greta Thunberg, the 16-year-old climate activist whose solo student strike has helped ignite a global youth movement, signaled that pressure would continue.
Sitting next to Guterres, Thunberg took the microphone and said the millions of young people who protested around the world Friday had made an impact. “We showed them we are united and that we young people are unstoppable,” she said.
From Guterres came a hat tip. “I encourage you to go on. I encourage you to keep your initiative, keep your mobilization and more and more to hold my generation accountable.”
Those protests have buoyed the efforts of U.N. officials to push for more ambitious climate action but haven’t necessarily made the job easy.
“The time window is closing and it’s dramatically short for what we have to do,” said Achim Steiner, head of the U.N. Development Program. “The protests are helpful because they show national leaders in their societies, in their countries, that the politics of climate change is changing and it is adding momentum and pressure to act.”
