Guterres Calls Climate Talks Critical Moment
The outgoing UN Secretary-General urged leaders to act now, citing a personal reckoning with scientists and the urgency of COP31.

António Guterres described the upcoming United Nations climate conference as a moment of truth, a phrase he repeated three times during a recent interview. The warning comes as world leaders prepare to gather in Turkey for COP31, scheduled for November 9 through 20. This will be Guterres' final major speech on the issue before his second and final term expires at the end of the year.
The Secretary-General's sense of urgency stems from a recent consultation with scientists. Before a major speech last year, Guterres intended to assert that the 1.5-degree Celsius warming limit set by the 2015 Paris Agreement remained achievable. Scientists told him the data no longer supported that claim. He described the news as an enormous shock and one of the most difficult days of his life, noting that the failure lies with political leadership rather than the world itself.
Guterres argued that many political systems lack the long-term strategic view necessary for consistent investment in climate solutions. He pointed to his tenure as Portugal's prime minister in the late 1990s as proof that long-term planning is possible. He also cited the global expansion of wind and solar power as a source of hope, though he warned that rising temperatures and extreme weather events continue to worsen.
The stakes became clear in August when floods in Nepal killed more than 1,400 people and left another 5,600 missing. Guterres recalled visiting the country's peaks in 2023 to warn of such disasters. He said the events came sooner than he expected and that climate change played a role in the severity of the flooding.
Former U.S. Vice President Al Gore praised Guterres as a forceful and accurate voice on the climate crisis. Laurence Tubiana, CEO of the European Climate Foundation, noted that Guterres pushed the issue further than any previous Secretary-General. Despite this recognition, Guterres acknowledged the limitations of his role. He stated that the position has no real power and limited funds, leaving the organization with only its voice to influence nations.
Guterres proposed that windfall profits from fossil fuel companies should be taxed to support countries suffering the most dramatic impacts of climate change. He also highlighted the growing energy demands of artificial intelligence as a compounding threat. As he prepares to step down, he offered three words of advice to his successor: tell the truth. He emphasized that climate change is an existential threat that must be taken seriously to protect human lives.
