COP31 talks unfold as 1.5C climate limit looks out of reach
NPR’s COP31 explainer, citing UNEP and IPCC, says the Paris 1.5C limit is slipping and that extra tenths of a degree change projected heat, reefs, storms and ice risk.
- New headline Was: “Why even a fraction of a degree can escalate climate change impacts”

Based on reporting by NPR
Delegates at COP31 in Turkey are negotiating against the Paris Agreement’s 1.5C limit, which NPR says is now widely treated as out of reach, with global average temperatures already near that mark and fossil-fuel emissions still rising1.
NPR cites a recent U.N. Environment Programme assessment that a best-case pathway is now about 1.7C to 1.8C of warming, versus about 2.8C by 2100 if emissions stay on their present course1.
The piece cites IPCC findings that most coral reefs would not survive as functioning ecosystems beyond about 2C, a Nature-linked assessment that a large share of coral species is already at extinction risk, and Potsdam Institute work that each extra tenth of a degree exposes tens of millions more people to dangerous heat1.
NPR says COP31 is not expected to produce major new emissions cuts and is instead discussing an electrification goal, and reports University of Exeter climate scientist Tim Lenton saying every avoided fraction of a degree still reduces harm1.
