High on Mauna Loa, the world’s largest volcano in Hawaii, sits an observatory built by scientist David Keeling in 1958. Since its inception, it has captured the pure air from the trade winds and measured its carbon dioxide (CO2) levels, creating what is now known as the Keeling Curve. This chart reveals that during the northern summer, CO2 levels dip as plants thrive, only to rise again in winter. It demonstrates how our planet breathes and shows alarming trends—like the steady increase in atmospheric CO2 from 313 parts per million (ppm) in 1958 to 430.67 ppm recently, coinciding with severe climate events like bushfires and flooding in Australia.
The Keeling Curve is plain and powerful, serving as the world’s most straightforward depiction of climate change. It highlights a crucial aspect of climate science that has developed over decades, proving the importance of long-term scientific dedication.
However, the stability of this observatory has recently come under threat due to political forces. The Trump administration proposed budget cuts that could end this vital research, just one element in a broader attack on climate science. These cuts were justified by claims of efficiency but provoke concern over the long-term impact on our understanding of climate change.
Historically, climate science blossomed in tandem with global cooperation, as seen with the Paris Agreement in 2015. That agreement aimed to limit global warming, but recent political actions threaten to unravel this progress. Commentators express anxiety over the diminishing appetite for robust climate policies, particularly in the U.S. where government-backed actions on renewables are questioned, while similar sentiments echo in Australia. Matt Kean, a former NSW treasurer, noted how this rhetoric hampers finding practical, national solutions to climate challenges.
Moreover, social media reactions to climate policy debates show a stark divide. Many favor renewable energy and push back against fossil fuel support, highlighting a generational gap in attitudes toward climate action. Recent statistics show that millennials and Gen Z are more likely to prioritize climate issues over older generations, signaling a shift in public sentiment that could shape future policy.
As we reflect on the importance of institutions like the Mauna Loa Observatory, it’s crucial to advocate for evidence-based climate action. Ensuring continued research and support for climate science is not just beneficial but necessary as we confront the challenges of a changing world.
