#climatecollapse: "Global heating will reach at least 1.8C under even the most optimistic future. Overshooting the 1.5C goal inscribed in the landmark Paris agreement of 2015 was now 'unavoidable' and... likely in the next few years. UNEP said: 'There are no good outcomes above 1.5C'." https://www.theguardian.com/environment/2026/sep/02/global-heating-warming-1-8c-best-case-scenario-un-united-nations-environment-programme-report

"Global heating will reach at least 1.8C under even the most optimistic future, well beyond the Paris agreement goal of 1.5C, according to a UN report. It said: “There are no good outcomes above 1.5C”. Crucially, the authors of the report, titled Limiting Overshoot, said the average global temperature could be returned to 1.5C this century only if heating stayed below about 1.8C." https://www.theguardian.com/environment/2026/sep/02/global-heating-warming-1-8c-best-case-scenario-un-united-nations-environment-programme-report
