NASA‘s Planned Cuts to Carbon Monitoring Satellites Draw Criticism
Table of Contents
NASA’s decision to discontinue its carbon-monitoring missions,including the Orbiting Carbon Observatory (OCO-3),is facing backlash from scientists and government officials who fear it will hinder efforts to understand and combat climate change. While private companies and non-profit organizations are increasing their capacity to monitor greenhouse gases from space, concerns remain about the loss of crucial long-term data and research capabilities provided by NASA’s dedicated missions.
The End of Key NASA Missions
NASA announced plans to end funding for OCO-3,along with the TEMPO (Tropospheric Emissions Monitoring Instrument) mission,citing budgetary constraints. https://spacepolicyonline.com/news/nasa-proposes-terminating-oco-3-tempo-in-fy2025-budget-request/ OCO-3, launched in 2019, has been providing valuable data on carbon dioxide concentrations in the atmosphere, building on the legacy of its predecessor, OCO-2.TEMPO, launched in 2023, focuses on monitoring air pollution across North America. https://www.nasa.gov/tempo/
The agency argues that these missions have achieved their primary objectives and that the data can be continued by other sources. Though, critics argue that ending these missions prematurely will create gaps in the long-term record needed to track climate trends and assess the effectiveness of mitigation strategies.
the Rise of Private and Non-Profit Monitoring
While NASA’s missions are being scaled back, the landscape of greenhouse gas monitoring is evolving with increased involvement from the private sector and non-profit organizations. Several companies now operate satellites capable of measuring atmospheric chemicals, but these have primarily focused on detecting localized methane emissions for regulatory purposes, rather than comprehensive global trends. https://arstechnica.com/science/2024/02/google-environmental-defense-fund-will-track-methane-emissions-from-space/
One notable example is the Carbon Mapper Coalition, a non-profit consortium launched last year. It includes contributors from NASA’s Jet Propulsion Laboratory (JPL) – the origin of the OCO instruments – and also Planet Labs, the California air Resources Board, universities, and private investment funds. https://carbonmapper.org/ Carbon Mapper aims to provide high-resolution data on methane and carbon dioxide emissions, helping to pinpoint sources and inform mitigation efforts.
Local Impacts and Concerns
The potential loss of NASA’s carbon-monitoring capabilities is also raising concerns at the local level.Government leaders in Montgomery County, Maryland, have set aspiring goals for greenhouse gas emission reductions – 80% by 2027 and 100% by 2035.Mark Elrich, the county executive, expressed concern that the termination of NASA’s missions “weakens our ability to hold polluters accountable.”
“This decision would… wipe out years of research that helps us understand greenhouse gas emissions, plant health, and the forces that are driving climate change,” Elrich stated in a recent press conference.
Why Continuous Monitoring Matters
Understanding greenhouse gas concentrations is crucial for several reasons:
Tracking Climate Change: Long-term data sets are essential for identifying trends and understanding the rate of climate change. Verifying Emissions Reductions: Accurate monitoring is needed to verify that countries and companies are meeting their emissions reduction commitments under agreements like the Paris Agreement. https://www.un.org/en/climatechange/paris-agreement
Identifying Emission Sources: Detailed data can definitely help pinpoint the sources of greenhouse gas emissions, allowing for targeted mitigation efforts.
Assessing Ecosystem health: Carbon dioxide uptake by plants and ecosystems plays a vital role in regulating the climate. Monitoring carbon fluxes helps assess the health and resilience of these ecosystems.
