A recent report warns that the world has only 130 billion tonnes of carbon dioxide remaining in its carbon budget to avoid surpassing 1.5°C of warming, which could be exhausted in just three years at current emission levels. With high temperatures recorded in 2024, experts express concern over the nearing thresholds established by the Paris Agreement. Key climate scientist Professor Joeri Rogelj emphasizes the urgency, noting that future emissions will significantly affect our capability to stay within safe warming limits.
The window to stay within 1.5°C is rapidly closing. Emissions over the next decade will determine how soon and how fast 1.5°C of warming is reached.
The carbon budget is worked out from the basis that the global warming we experience is largely determined by the total amount of carbon dioxide that is ever emitted into the atmosphere.
The data shows that we are rapidly approaching the warming limits set out by the Paris Climate Agreement and that the remaining 'carbon budget' is dwindling.
A single year above 1.5°C of warming doesn't mean that the Paris Agreement has been breached, but it does show that the world is getting dangerously close to this threshold.
