Imperial College London: Window to avoid 1.5C of warming will close before 2030 if emissions not reduced
Window to avoid 1.5°C of warming will close before 2030 if emissions not reducedby Sam Ezra Fraser-Baxter, Hayley Dunning
30 October 2023
Without rapid carbon dioxide emission reductions, the world has a 50% chance of locking in 1.5°C of warming before 2030 according to a new study.
The study, led by Imperial College London researchers and published today in Nature Climate Change, is the most up-to-date and comprehensive analysis of the global carbon budget. The carbon budget is an estimate of the amount of carbon dioxide emissions that can be emitted while keeping global warming below certain temperature limits.
The Paris Agreement aims to limit global temperature increase to well below 2°C above preindustrial levels and pursue efforts to limit it to 1.5°C. The remaining carbon budget is commonly used to assess global progress against these targets.
The new study estimates that for a 50% chance of limiting warming to 1.5°C, there are less than 250 gigatonnes of carbon dioxide left in the global carbon budget.
