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

As countries prepare for the upcoming COP31 climate conference in Turkey, a new UN report reveals that global temperatures are now projected to rise between 1.7-1.8 degrees Celsius above pre-industrial levels by mid-century, even under the most optimistic scenarios. The United Nations Environment Programme's (UNEP) annual Emissions Gap Report indicates that current national climate plans would result in only a 5% to 8% reduction in emissions by 2030 and an 11-15% reduction by 2035, far short of the necessary reductions. To achieve even the best-case scenario outlined in the report, global emissions must decrease by 45% by 2035 and 69% by 2040 from 2025 levels. UN Secretary-General Antonio Guterres emphasized that urgent action is needed to avoid further devastating impacts of climate change such as extreme weather events.

Despite a rapid expansion of renewable energy and climate policies that are reducing emissions in many countries, the report said “urgent and stringent” cuts were still needed to achieve that best-case outcome. asserted

Current national plans would cut emissions by only 5% to 8% by 2030 and 11-15% by 2035. asserted

The report projected global warming of 2.8 deg C by 2100 under current policies, or 2.6 deg C if countries fully implement existing climate pledges. asserted
countries → project → pledges
Both estimates are higher than the 2025 projections, reflecting the US withdrawal from the Paris Agreement and revised assessments of historical emissions. asserted

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
