Wildfires Drive Record Surge in Global CO₂ Levels
In 2024, wildfires around the globe contributed to a historic increase in carbon dioxide (CO₂) levels, reaching 427 ppm at the Mauna Loa observatory in Hawaii, The Guardian reported.
This marks a 3.6 ppm rise, significantly higher than the pre-industrial level of 280 ppm. The surge, attributed to both intense forest fires and ongoing emissions from fossil fuels, surprised scientists.
The El Niño climate cycle exacerbated conditions, leading to hotter and drier weather, particularly in the tropics. Despite this, experts noted that the rise in CO₂ would likely have occurred even without El Niño. The global average temperature also reached a new peak in 2024, surpassing the 1.5°C threshold established by the Paris Agreement for the first time.
UN Secretary-General António Guterres condemned the fossil fuel industry for prioritizing profits while contributing to climate destruction. He emphasized the urgent need for governments to invest in clean energy, noting that they currently spend nine times more subsidizing fossil fuels than promoting renewable alternatives.
In addition to the alarming rise in CO₂ levels, scientists have observed a significant increase in the frequency and intensity of extreme weather events globally. This includes more severe hurricanes, prolonged droughts, and unprecedented flooding, all linked to climate change. The Intergovernmental Panel on Climate Change (IPCC) has warned that without substantial reductions in greenhouse gas emissions, these extreme weather patterns will continue to worsen, posing severe threats to ecosystems, agriculture, and human health.
Moreover, the economic impact of climate-related disasters is escalating, with damages costing billions annually, further stressing the importance of immediate and effective climate action.
Looking ahead, CO₂ levels in 2025 are projected to rise by 2.3 ppm, still above the target necessary to limit global heating. Scientists stress the importance of immediate action to mitigate the climate crisis and reduce emissions.
