A briefing by the NewClimate Institute reporting that global warming projections for 2100 have remained stagnant since 2021, with current policies leading to a median projected warming of 2.7°C.

The November 2024 Warming Projections Global Update by the NewClimate Institute reports that global warming projections for 2100 have stagnated over the last three years. Current policies set the world on a path toward 2.7°C of warming, while the most optimistic scenario, assuming full implementation of all announced targets, projects 1.9°C. The report highlights a critical disconnect between the escalating climate crisis and the urgency of government policy implementation, noting that while renewable energy growth is record-breaking, it is being offset by all-time high fossil fuel subsidies.

This briefing by the Climate Action Tracker (CAT) evaluates the impact of recent net zero pledges on global warming projections, noting that while targets have lowered end-of-century estimates, a significant gap remains between current policies and the goals required to limit warming to 1.5°C.
