UNEP report warns global warming will exceed 1.5°C threshold

climate overshoot 1.5C warming threshold UNEP report Paris Agreement emissions reduction

A new report from the United Nations Environment Programme (UNEP) warns that the world is on track to exceed the 1.5°C global warming threshold established by the Paris Agreement within the next few years. Current temperatures are estimated to be approximately 1.4°C above pre-industrial levels.

The report introduces an 'overshoot, peak and decline' framework as a strategy to manage this inevitable breach. This approach involves making immediate, aggressive cuts to greenhouse gas emissions to limit the maximum temperature rise, which could potentially be contained at 1.8°C even in optimistic scenarios. The goal is to eventually return to safer temperature levels through sustained emission reductions and carbon dioxide removal technologies.

However, the report emphasizes that exceeding 1.5°C carries severe risks, including more intense extreme weather, rising sea levels, and irreversible tipping points such as the melting of ice sheets and the loss of the Amazon rainforest. Pacific Island leaders have expressed grave concern, noting that such an overshoot poses an existential threat to their communities and food security, particularly tuna stocks.

While the report highlights the necessity of carbon removal, some experts and UNEP officials express skepticism regarding the current capacity and cost-effectiveness of technologies like carbon capture and storage (CCS) to solve the crisis, stressing that the primary focus must remain on the rapid phase-out of fossil fuels.
