In a striking revelation, scientists have reported that levels of carbon dioxide (CO2), the primary planet-warming gas, surged more dramatically in 2024 than in any previous year. This latest rise leaves international climate targets precariously unachievable. Following record fossil fuel emissions and reduced absorption from natural sources like forests and oceans, the concentration of CO2 is now over 50% higher than pre-industrial levels.

Pandemic of Carbon: 2024 Sees Unprecedented Rise in CO2 Levels
The consequences of human activity are stark as CO2 levels soar to alarming new heights, challenging global climate goals.
Last week marked a significant milestone in climate history, as it was confirmed that 2024 was the hottest year recorded, with average global temperatures surpassing the critical threshold of 1.5°C above pre-industrial levels. While this spike doesn't directly breach the long-term Paris Agreement target, continuous increases in CO2 emissions signify perilous implications for the future climate scenario, noted the Met Office.
The reasons behind this alarming situation are clear and multifaceted. A combination of rampant fossil fuel usage, deforestation, and natural phenomena like El Niño has compounded the CO2 accumulation process. Preliminary data revealed that the carbon emissions from fossil fuels hit new peaks last year, while natural ecosystems struggled to keep pace.
El Niño's effects—marked by elevated sea temperatures—significantly influenced the climate, reducing the ability of natural carbon sinks to absorb CO2. This phenomenon occurred alongside widespread wildfires, which are typically exacerbated in regions experiencing elevated temperatures. An analysis from the Global Carbon Project highlights that CO2 levels escalated by nearly 3.6 parts per million, reaching a record-high of over 424 ppm, the most substantial annual increase since measurements began in 1958 in Hawaii.
Prominent scientists warn that the trajectory of climate change puts the world into “uncharted territory,” as the capacity for natural systems to absorb carbon becomes increasingly compromised. Observations show alarming changes, such as the Arctic tundra morphing into a net CO2 source due to warming, and the Amazon rainforest's declining absorption capability due to human-induced drought and deforestation.
Amid growing fears about the resilience of natural carbon sinks, the Met Office forecasts that while CO2 levels may not rise as drastically in 2025, they will still fall sharply short of what is necessary to meet global climate objectives. The recent shift to La Niña conditions offers a temporary reprieve, promoting slightly cooler temperatures, yet experts warn that the underlying trend of CO2 accumulation continues.
The journey toward achieving climate stability demands urgent action. Scientists are calling for immediate focus on understanding and mitigating these escalating CO2 levels to safeguard the planet for future generations.
