UNEP says 1.5°C ‘overshoot’ is now unavoidable. Here’s what this means for climate action

A new report by the United Nations Environment Programme (UNEP) titled “Limiting Overshoot” states that exceeding the 1.5°C global warming target above pre-industrial levels is now 'unavoidable', with temperatures expected to peak at around 1.8°C even in optimistic scenarios. The article explains the significance of the 1.5°C target, a key outcome of the 2015 Paris Agreement, and the risks associated with overshooting it, including irreversible damage to ecosystems and climate systems. It emphasizes that while overshoot is likely, the goal should be to keep the peak warming as low and short as possible, requiring massive emissions reductions, carbon dioxide removal, and integrated mitigation and adaptation strategies. The report also highlights the uneven burden of climate change impacts on vulnerable nations.
