A new United Nations Environment Programme report concludes that the world will exceed the 1.5 C global-warming limit established under the 2015 Paris climate accord within the next few years. Although the threshold was intended to prevent the most severe climate impacts, the report says it is no longer realistically possible to avoid temporarily surpassing it. Current government policies could produce warming of about 2.6 C above pre-industrial levels by 2100, while the most ambitious pathway would peak at approximately 1.8 C around mid-century.
Rather than abandoning the 1.5 C goal, UN officials and scientists now advocate an “overshoot” strategy: allow temperatures to rise above the threshold, then gradually reduce them below it by ending fossil-fuel use and removing carbon dioxide from the atmosphere. The report warns that even a temporary overshoot would bring decades of increased extreme weather, sea-level rise, melting ice, food and water insecurity, economic damage, extinctions and worsening health impacts. It also highlights possible irreversible tipping points, including the collapse of major ice sheets, Amazon rainforest loss and disruption of Atlantic Ocean circulation.
Experts stress that every fraction of a degree of avoided warming would reduce damage, but adaptation will need to become transformative rather than incremental. Elisabeth Gilmore notes that Canada is warming at roughly twice the global average, with even greater increases in the Arctic. Carbon removal through tree planting alone would have limited effects, so the report calls for newer technologies, despite concerns about their expense and reliability. Overall, the article presents the report as a sober reassessment of climate policy: preventing all dangerous warming is no longer possible, but reducing peak warming and eventually restoring safer conditions remain achievable objectives.

A new UN Environment Programme (UNEP) report says the world can no longer avoid temporarily exceeding the 1.5°C warming limit set by the Paris Agreement. The most realistic pathway is now to overshoot the threshold, reach a peak, and then bring temperatures back below it. UNEP projects warming of 1.8°C in the best-case scenario and more than 2°C in others, warning that climate impacts and the risk of tipping points worsen with every additional fraction of a degree. UN Secretary-General António Guterres says the overshoot must be made as small and brief as possible.
Renewable energy is expanding rapidly, but a separate Energy Transitions Commission (ETC) report identifies a “paradox of progress”: record clean-energy growth is not yet causing global emissions to decline. Annual clean-energy investment has reached €1.9 trillion, but it meets only about 40 per cent of rising energy demand. Heatwaves are increasing air-conditioning use, while artificial intelligence is driving rapid growth in data-centre electricity consumption. Overloaded and outdated grids are also delaying new renewable projects, leaving hundreds of gigawatts waiting for connections in Europe and the United States. Consequently, emissions are plateauing and the world is currently on track for approximately 2.5°C of warming.
The reports recommend cutting methane emissions quickly, especially from oil and gas operations, food waste and landfills. Countries should redirect investment from high-emission infrastructure toward renewables and other low-emission alternatives, expand renewable electricity to 60–70 per cent of global generation by 2030, and accelerate grid upgrades, storage and demand flexibility. Decarbonising heating, industry and transport is also essential. Energy efficiency, electrification, and changes in transport and dietary habits can reduce demand, although UNEP stresses that policy—not individual action alone—must drive these changes. Faster emissions cuts would also reduce reliance on uncertain carbon dioxide removal technologies.

The United Nations Environment Programme warns that global temperatures are likely to exceed the 1.5°C warming threshold within the next few years. The limit, established under the 2015 Paris climate accord, is measured against pre-industrial temperatures and is intended to prevent the most severe consequences of climate change. Breaching it would intensify extreme weather, glacier loss, ecosystem damage and sea-level rise, while increasing threats to human health, food and water security, cities and infrastructure.
The UN says governments have not reduced greenhouse-gas emissions quickly enough, leaving the world exposed to worsening climate impacts. UNEP Executive Director Inger Andersen described the situation as a consequence of political inaction and said extreme heatwaves are already becoming more severe, longer-lasting and deadlier.
According to the assessment, even the most optimistic pathway would see global temperatures peak at approximately 1.8°C above pre-industrial levels before potentially declining to 1.5°C later in the century. Returning below the threshold remains technically possible, but the report emphasizes that it would require rapid and deep emissions reductions combined with carbon dioxide removal on a massive scale. Proposed measures include restoring forests and deploying technologies that extract carbon directly from the atmosphere.
Andersen said renewable energy is already cheaper than fossil fuels in many markets, but countries are not acting quickly enough. She warned that exceeding 1.8°C would make returning to 1.5°C extremely difficult and could produce “fundamental and calamitous” consequences for humanity. UN Secretary-General Antonio Guterres had previously warned that temperatures could temporarily exceed the 1.5°C threshold.
