The United Nations Environment Programme (UNEP) reported on October 21, 2026, that the world is now certain to exceed the 1.5°C global warming limit established by the Paris Climate Agreement. Decades of insufficient climate action have made exceeding this threshold "imminent and unavoidable". Under current policies, global warming could reach 2.8°C this century.

This news signals a fundamental shift in global climate strategy, moving from preventing the 1.5°C breach to mitigating its severity and duration. The report now urges focus on minimizing the extent and duration of a temperature "overshoot" and aiming for a return to 1.5°C by the end of the century. This affects future climate policies worldwide and directly impacts the lives of millions facing increased climate risks.

What the records show

UNEP's "Emissions Gap Report 2026: The Point of Return," released on October 21, 2026, confirmed that the world will unavoidably breach the 1.5°C warming limit. The report states that "decades of insufficient climate action" have made exceeding the 1.5°C threshold "imminent and unavoidable". Projections indicate that under current policies, global warming could reach 2.8°C by the end of this century. To minimize this overshoot and return temperatures to 1.5°C by 2100, countries must cut greenhouse gas emissions by an average annual rate of 5.7 percent between 2025 and 2035. The report emphasizes that the opportunity to limit warming to 1.5°C "with no or limited overshoot has been lost".

What changed and for whom

The projections detailed in the 2026 report have worsened compared to those in the previous year's edition. This deterioration is partly attributed to the United States' withdrawal from the Paris Agreement and revised estimates of historical emissions. The new national climate plans submitted since the last report have had a negligible impact on the warming outlook. This situation fundamentally alters the global climate objective from preventing the breach to managing an "overshoot," requiring urgent and stringent cuts to minimize its magnitude and duration.

What has been said publicly

The report's title, "The Point of Return," highlights the new strategic objective: to return to 1.5°C by the end of the century after an inevitable overshoot. UN Secretary-General António Guterres stated that "overshoot is not surrender" and emphasized that it is still possible to return global temperatures to 1.5°C above pre-industrial levels by the end of the century. He urged for deep and fast emissions cuts to make this return possible.

What we could not confirm

We could not confirm specific new climate policies or commitments being adopted by major emitting nations in direct response to the findings of the UNEP Emissions Gap Report 2026.
