Record-Breaking Surge in Earth’s Atmospheric CO2 Levels in 2024

The global carbon dioxide (CO2) levels have reached unprecedented heights in 2024, signaling a pressing environmental crisis. According to the World Meteorological Organization (WMO), the average concentration of CO2 surged by 3.5 parts per million (ppm) between 2023 and 2024, bringing the total to 423.9 ppm. This increase represents the largest yearly jump since measurements began in 1957.
Record-Breaking Surge in Earth’s Atmospheric CO2 Levels in 2024
This dramatic rise in CO2 levels exceeds last year’s increase of 2.3 ppm and reflects a troubling trend of accelerating emissions. Historical data indicates that the last time atmospheric CO2 reached similar levels was between 3 million and 5 million years ago. The WMO warns that the excess CO2 will continue to warm the planet for centuries.
Key Drivers of the Increase
Several factors contribute to the record surge in atmospheric CO2:
- Ongoing emissions from fossil fuels
- Increased carbon outputs from wildfires
- Decreased carbon uptake by land and oceans
Research highlights that emissions from fossil fuels remain at an all-time high. Additionally, the El Niño weather pattern has elevated global temperatures, affecting carbon absorption. Notably, the loss of tropical forests in 2024 was double that of 2023.
Impact of El Niño on Carbon Uptake
The recent El Niño events have exacerbated conditions that hinder carbon intake by terrestrial ecosystems. Richard Allan from the University of Reading notes that while it’s common for tropical regions to become drier during such warm periods, this could signify a more concerning trend of diminishing carbon absorption capabilities.
Long-term Consequences
Climate scientists are increasingly worried about the planet’s ability to absorb CO2. Zeke Hausfather from the Breakthrough Institute points out trends suggesting that the land sink for carbon is declining, particularly in the northern hemisphere. The long-term implications of this decline could further hinder efforts to combat climate change.
Urgent Call to Action
The situation calls for immediate action to reduce fossil fuel emissions, as emphasized by Piers Forster of the University of Leeds. The persistent rise in CO2 concentrations demands an urgent global response to mitigate further environmental degradation.
