Quick Summary

A UN Environment Programme report released on October 21 projects higher global temperature increases than previously estimated, even under optimistic scenarios. The best-case scenario sees temperatures rising by 1.7 to 1.8 degrees Celsius above pre-industrial levels by mid-century and warming of 2.6 to 2.8 degrees Celsius by the end of the century due to insufficient current policies. To achieve the most favorable outcome, global greenhouse gas emissions would need to decrease dramatically: by 18% from 2025 levels by 2030, 45% by 2035, and 69% by 2040, far beyond what current national plans propose.

Story summary

The United Nations Environment Programme (UNEP) released a report on October 21 projecting that global warming will exceed previous estimates. Even in the most optimistic scenario, average temperatures are set to rise by 1.7-1.8 degrees Celsius above pre-industrial levels by mid-century. Despite an increase in renewable energy and climate policies reducing emissions in many countries, urgent and stringent cuts of 18%, 45%, and 69% from 2025 levels are needed by 2030, 2035, and 2040 respectively to achieve this outcome. The report notes that current national plans would only cut emissions by 5-8% by 2030 and 11-15% by 2035, which falls short of the required reductions. Under current policies, global warming is projected to reach 2.8 degrees Celsius by 2100, or 2.6 degrees Celsius if countries fully implement existing climate pledges. These projections are higher than previous estimates due to factors like the US withdrawal from the Paris Agreement and revised assessments of historical emissions. UN Secretary-General Antonio Guterres emphasized the importance of not giving up on efforts to rein in emissions ahead of COP31, scheduled to take place in Turkey.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.

We can still keep it as small and as short as possible – and bring temperatures back below 1.5 deg C by the end of the century," he said. asserted
he → keep → century
Under the 2015 Paris Agreement, countries agreed to try to keep the average temperature increase at well below 2 deg C and ideally 1.5 deg C. As limiting warming to 1.5 deg C with no or limited overshoot was no longer considered possible, the UN Environment Programme said its new "lowest possible" overshoot scenario gives roughly a 50% chance that temperatures could return to 1.5 deg C or below by 2100. uncertain
temperatures → agree → 2100
The report said climate plans submitted since 2025 had made virtually no difference to future warming projections, and that returning to 1.5 deg C would depend on large-scale carbon removal, the feasibility of which was uncertain. asserted
feasibility → say → which
