The evidence that we are facing imminent and irreversible climate breakdown is now damning: 2024 marked the first year that average global temperatures rose above the internationally agreed 1.5°C target, the end of the warmest decade on record, and an all-time high for fossil-fuel emissions.

The world is perilously close to exceeding the carbon budget, the amount of CO2 that can be added to the atmosphere without causing long-term global temperatures to rise above 1.5°C. If emissions continue at today’s levels, we have just two years before the world’s carbon budget is used up. Put simply, without urgent, government-led collective action to tackle emissions, we will soon be facing increasingly catastrophic and irreversible impacts of climate change.
