António Guterres and the United Nations acknowledge global temperatures will inevitably exceed the 1.5-degree Celsius warming limit.

The United Nations Environment Programme announced a new report stating that the world will inevitably cross the 1.5-degree Celsius warming threshold within the next few years. This threshold, established by the 2015 Paris climate accord, was previously considered a target to prevent the worst effects of global warming. Under current policies, global temperatures are projected to reach 2.6 degrees Celsius above pre-industrial levels by 2100. António Guterres, the United Nations Secretary-General, stated that humanity is speeding past the limit to avoid climate catastrophe. The report suggests a new strategy of "overshoot," where the world passes the 1.5-degree mark and then works to bring temperatures back down. To achieve this, the administration must prioritize rapid emissions reductions and carbon dioxide removal. The report emphasizes that while the1.5-degree limit is not a "magical climate cliff," every fraction of a degree avoided reduces risk. Policymakers are urged to simultaneously pursue mitigation and adaptation. While some impacts are unavoidable, the report notes that every investment in resilience preserves future options for a warmer world.
