UN Chief Warns: No Peace on a Burning Planet at COP31 2026

The UN secretary general, António Guterres, delivered a stark warning at the COP31 climate summit: you cannot build peace on a burning planet. In his final climate press conference as secretary general on Friday, Guterres emphasized that tackling the climate crisis is central to all of human life and must be at the forefront of global governance.

His emotional farewell address underscored the interconnectedness of climate action with peace, poverty eradication, and youth prosperity. Guterres has been the most forthright secretary general yet on climate, repeatedly castigating fossil fuel companies and recalcitrant governments.

Guterres’s Parting Shot: Climate Central to Global Stability

Guterres made it clear that climate change does not stay in its lane. “It drives anger and displacement around the world. It wipes out development gains built over decades. It pushes countries deeper into deficit. It aggravates competition for land and water,” he said. This framing positions climate action not as an environmental side issue but as a prerequisite for global stability.

His message to his successor was unambiguous: the UN must continue to place the climate at the top of the global agenda. With his term ending in December and no successor yet named, fears are widespread that the next incumbent will downplay the climate crisis.

Why This Matters: The Stakes for Global Governance

Guterres’s speech comes at a critical juncture. The UN’s ability to galvanize international cooperation on climate is under threat, especially after Donald Trump attempted to influence the selection of the next secretary general. A shift away from climate leadership could undermine global efforts to curb emissions and adapt to worsening impacts.

The outgoing secretary general’s emphasis on the climate-peace nexus is a reminder that instability, conflict, and displacement are often fueled by climate-related stresses. As Guterres put it, “You cannot eradicate poverty when climate disasters keep throwing people back into it.” The background to this story is set out in COP31 Fossil Fuel Influence: 103 Groups at Climate Talks.

Key Takeaways from Guterres’s COP31 Address

• Climate action is inseparable from peace and security, according to Guterres.
• The UN must maintain climate as a top priority despite political pressures.
• Climate disasters reverse development gains and deepen deficits.
• Young people’s future depends on protecting natural systems.
• Guterres’s successor will face intense scrutiny over their climate stance.

The Road Ahead: What to Watch

As the COP31 summit continues, all eyes are on how other leaders respond to Guterres’s call. The selection of the next UN secretary general will be a key indicator of the international community’s commitment to climate action. Meanwhile, civil society and youth movements are likely to ramp up pressure on governments to fill the leadership void.

Guterres’s legacy as a climate champion will be tested in the coming months. His successor must decide whether to build on his efforts or retreat from the frontlines of the climate fight.
