UN chief urges immediate methane cuts, calls climate adaptation a present-day priority

Secretary-General António Guterres returned from London Climate Action Week and told UN forums that climate adaptation is no longer a distant priority but a present-day imperative, the UN spokesperson said at a briefing on June 22.

"It's about managing risks in real-time," the spokesperson said, summarizing the Secretary‑General's remarks that searing heat in London and elsewhere shows the urgency of immediate measures. The Secretary‑General emphasized the need for drastic emissions cuts, a rapid shift away from fossil fuels, and steps to end deforestation.

The spokesperson said the Secretary‑General launched a global call to action on methane, describing methane as "the single fastest break we can pull on a warming planet." The official framed methane reduction as a near-term intervention that could slow warming while longer-term measures take hold.

The Secretary‑General also addressed the Climate and Development Finance Forum 2026 and attended events on super pollutants. The briefing noted that the Secretary‑General received the Kew International Medal for leadership on climate and biodiversity and dedicated the award to the United Nations and UN staff.

Why it matters: Climate impacts are occurring now, the briefing said, and governments must protect vulnerable populations through better early warning systems and targeted support. At the same time, the Secretary‑General tied short-term pollutant action to the wider task of rapidly cutting CO2 emissions and protecting nature.

The briefing concluded by urging member states and partners to accelerate both mitigation and adaptation measures; no immediate, binding international decisions were announced at the briefing.
