Join the Movement: Climate Scientists Encourage CO2 Tracking Amid Looming US Emission Cuts

Climate scientists are sounding the alarm about potential budget cuts that could end vital carbon dioxide (CO₂) monitoring in the U.S. This data is crucial for understanding and tackling climate change. Pierre Friedlingstein from the University of Exeter emphasizes that someone needs to step up to fill this gap. He leads the Global Carbon Budget, which tracks CO₂ emissions and absorption worldwide.

The National Oceanic and Atmospheric Administration (NOAA) plays a critical role in these efforts. However, recent proposals could eliminate its funding for climate research and cut its workforce by more than 2,000 people. This includes shutting down essential facilities like the Mauna Loa Observatory in Hawaii, known for its long-term CO₂ monitoring since 1957.

Ralph Keeling from the Scripps Institution of Oceanography warns that if NOAA’s work ceases, we risk losing the ability to accurately track greenhouse gas flows globally. NOAA not only measures CO₂ levels across various sites but also analyzes global data to understand atmospheric changes. “If the NOAA effort is terminated, we lose critical baseline data,” Keeling states.

Even if other organizations take over, Friedlingstein cautions that they face challenges in maintaining long-term monitoring consistency. Transitioning to new monitoring systems could distort trends and data accuracy. The Mauna Loa site is particularly irreplaceable for establishing reliable global averages of CO₂ and understanding differences between northern and southern hemispheres.

Although satellites can track CO₂ levels, they measure across entire air columns rather than at specific locations, limiting their effectiveness as substitutes. This means that without NOAA, tracking CO₂ accurately will be tricky, especially in regions like the South Pole, where monitoring relies heavily on NOAA’s support.

The European Union’s Copernicus Atmosphere Monitoring Service might provide assistance, but so far, there’s been no commitment to directly replace NOAA’s contributions. Observing and combating climate change needs continuous, reliable data, and the loss of NOAA would be a significant blow.

Recent statistics reveal a growing global concern about climate change. A survey by the Pew Research Center shows that 70% of Americans view climate change as a major threat, underscoring the importance of robust monitoring systems. As the effects of climate change become increasingly apparent, the need for accurate data and consistent monitoring has never been more urgent.

In summary, the potential cuts to NOAA threaten not only crucial carbon monitoring but also our understanding of climate dynamics. Maintaining consistent, reliable data is essential for effective climate action.
