The UN warns of a "hellish" 3C global heating scenario, with current policies insufficient to prevent it. Temperature records have been broken in 2023, causing heatwaves, floods, and droughts. Implementing promised policies would only reduce the rise to 2.5C, still catastrophic. To meet the 1.5C target, 22bn tonnes of CO2 must be cut by 2030. Existing pledges are insufficient, with global emissions projected to be 2% below 2019 levels, far from the 43% cut needed.
