The world is likely to exceed a key global warming target soon. Now what?
Expected but sobering.
That’s how climate experts describe the new findings from the United Nations Environment Programme (UNEP). The recently released Emissions Gap Report 2025 warns that the world is on track to surpass the Paris Agreement’s most ambitious target limiting global warming to 1.5°C above pre-industrial levels within the next decade.
This moment has long been dreaded by climate advocates who hoped that breaching the 1.5°C threshold would be avoided for many decades, if not entirely. Keeping global temperatures below this limit is seen as crucial to preventing the worst effects of climate change extreme droughts, deadly heatwaves, floods, and storms.
“Despite all the warnings, the world has continued to emit greenhouse gases at record levels,” said Martin Krause, UNEP’s Director of Climate Change Division. “This conclusion wasn’t unexpected—but it should be a wake-up call to everyone. Climate change is real, it’s happening, and unless we act now, the consequences will be severe.”
The report paints a mixed picture. On one hand, global climate action has made measurable progress: when the Paris Agreement was signed in 2015, the planet was heading toward a catastrophic 3–3.5°C of warming. Thanks to strengthened national pledges, that projection has dropped to about 2.3–2.5°C by the end of the century. On the other hand, this is still far above safe limits.
Even if all current national commitments are fully implemented, emissions will only fall by 12–15% by 2035 far short of the 55% reduction needed to stay on the 1.5°C pathway, or even the 35% needed to cap warming at 2°C.
Overshooting the 1.5°C target now seems inevitable, but experts stress that the exceedance must be as minimal and short-lived as possible. UNEP’s modeling suggests that with rapid emissions cuts, global temperatures could peak near 1.8°C before cooling back below 1.5°C by century’s end.
The message from the Emissions Gap Report 2025 is clear: the world still has a window—narrow but open—to change course. Accelerating clean energy transitions, ending fossil fuel dependence, and scaling up climate finance are not just technical imperatives; they are moral ones. Every fraction of a degree matters, and every year of delay makes the challenge harder.
The time to act decisively is now.
