World on Track for 2.6°C as UN Warns Emissions Cuts Fall Far Short

The United Nations says global efforts to cut emissions are failing to meet the Paris climate goals. In a new report, the UN Environment Programme (UNEP) warns that current commitments put the world on a path to 2.6°C of warming this century — far above the 1.5°C target set by the Paris Agreement [267866].

A separate UN report released Wednesday says the world will inevitably exceed the 1.5-degree Celsius warming target within the next few years. According to the report, the focus must now shift to limiting the duration of this "overshoot" period and eventually bringing global average temperatures back down [267932]. The findings come just ahead of the annual UN climate summit, where nations will discuss next steps [267932].

The UNEP report highlights a stark gap between what countries promise and what they actually do to fight global warming. It also underscores the difficult task facing political leaders at the COP31 climate summit, which is scheduled to take place next month in Turkey [267866].

The agency said the world must cut carbon emissions by nearly one-fifth in the next four years, and by almost half within a decade, to avoid a disastrous overshoot of climate targets. The "window has closed" on holding temperature rises to 1.5C, the level scientists say is needed to prevent the worst climate impacts, but UNEP said limiting the overshoot of that target is still possible [267356]. It called for urgent action to close the gap between current emissions and the cuts needed [267356].

New data shows that while the rate of global emissions growth has fallen, total emissions remain at record highs. Experts warn that current trends put the 2°C limit at serious risk, and that crossing that threshold would bring more extreme heat, rising seas, and harder-to-reverse climate damage. The message is clear: slower growth is not enough — emissions must fall quickly and sharply to avoid the worst outcomes [267674].
