The carbon budget is the limit to how much CO₂ can be put into the atmosphere before global temperatures become dangerously hot.
It is calculated how much CO₂ can be released to have a good chance of keeping global warming below 1.5°C.
Approximately 500 billion tons of CO₂ can be released starting from 2020 to maintain a 50% chance of staying below 1.5°C.
The world currently adds about 40 billion tons of CO₂ to the atmosphere each year, depleting the carbon budget rapidly.
At the current rate, the carbon budget could be exhausted in just over a decade, leading to increased extreme weather events and environmental damage.
The carbon budget underscores the importance of understanding the time left to cut emissions in line with climate goals and the urgency of transitioning to cleaner energy sources.
Scientists and advocates use the carbon budget to call for stronger climate action, highlighting the insufficiency of current emission reduction efforts.
The carbon budget serves as a warning signal, emphasizing the need to accelerate and improve efforts to meet climate goals.
An analogy is made between the carbon budget and a national debt clock, suggesting the idea of a carbon budget countdown as a reminder of the urgency of the situation.
