UN report warns of imminent climate target breach

A new report from the UN Environment Programme (UNEP) released on Wednesday indicates that the world will inevitably surpass the 1.5-degree Celsius warming target set by the Paris Agreement. Even under the most optimistic scenarios, temperatures are projected to rise by 1.7-1.8 degrees Celsius above pre-industrial levels by the middle of the century, with current policies leading to a potential 2.8-degree rise by 2100. UNEP Executive Director Inger Andersen stated that while the window to remain within the 1.5-degree limit has effectively closed, international efforts must now focus on making the temperature 'overshoot' as brief as possible.

To mitigate long-term impacts, the report emphasizes that urgent and stringent emission cuts are required. Specifically, global greenhouse gas emissions must fall by 18% from 2025 levels by 2030, 45% by 2035, and 69% by 2040. Current national plans are projected to yield only a 5-8% reduction by 2030. The report attributes these higher-than-expected temperature projections to several factors, including the United States' withdrawal from the Paris Agreement and revised assessments regarding historical emission data.

This findings are intended to guide discussions at the upcoming COP31 climate summit in Turkey, scheduled for next month. UN Secretary-General António Guterres urged global leaders to maintain efforts to address emissions, noting that these are the primary drivers of extreme weather events such as floods.
