Scientists confirm that atmospheric CO2 levels experienced unprecedented growth in 2024, complicating efforts to limit global warming to 1.5C. The increase is primarily driven by fossil fuel emissions, with natural carbon absorption declining due to wildfires and drought.
Rising CO2 Levels Threaten Global Climate Goals: 2024 Breaks Records
Rising CO2 Levels Threaten Global Climate Goals: 2024 Breaks Records
Record temperatures were recorded in 2024 as carbon dioxide levels surged, jeopardizing climate targets.
In 2024, the world experienced an alarming rise in carbon dioxide (CO2) levels, which exceeded previous records. This increase presents a significant challenge for global climate initiatives aimed at keeping temperature rises within 1.5C above pre-industrial levels, as recognized at the Paris Agreement in 2015. Current CO2 concentrations are over 50% higher than those recorded prior to widespread fossil fuel combustion, reflecting humanity's heavy reliance on coal, oil, and gas.
Experts from the Met Office revealed unsettling data, contributing to claims that fossil fuel emissions reached unprecedented heights last year, while natural environments struggled to absorb CO2 due to rampant wildfires and droughts. This imbalance has resulted in CO2 levels soaring to new highs, a trend generally inconsistent with the international climate pledge.
2024 marked the first occurrence where annual temperatures surpassed the 1.5C threshold above pre-industrial levels, although it does not equate to a permanent breach of the Paris Agreement’s long-term goals. Richard Betts of the Met Office criticized the accelerating rise in CO2, stating it is “incompatible” with ambitions to curb global warming.
Historical data collected over the last two million years suggests that CO2 levels are at their highest, attributed largely to human activity and deforestation. Variations in the rate of CO2 absorption by natural ecosystems contribute to fluctuations in yearly CO2 output. Despite absorbing nearly half of humanity's emissions, natural carbon sinks like forests and oceans are increasingly hampered by extreme weather events.
Following a record increase of nearly 3.6 parts per million in CO2 concentrations from 2023 to 2024, monitoring stations like Mauna Loa in Hawaii continue to witness concerning trends. Ralph Keeling, who oversees its climate measurements, emphasized the urgency of the situation, warning about uncharted territory in climate change.
The degradation of natural carbon sinks, particularly in vulnerable regions like the Arctic tundra and the Amazon rainforest, raises serious concerns about their future capability to absorb CO2 amid ongoing environmental changes. The Met Office forecasts a lesser increase in CO2 levels for 2025 but cautions that the trajectory remains dangerously off-course in regards to the 1.5C target. With La Niña now replacing El Niño conditions, there might be a temporary pause in extreme temperatures, but experts assert that long-term warming is inevitable due to ongoing CO2 accumulation.
