Do Global Pandemics Affect Lunar Temperatures?

Can a global pandemic impact the moon’s surface temperatures? A study in 2024 suggested that global lockdowns during COVID-19 led to a decrease in heat radiation reaching the Moon from Earth. However, recent research disputes these findings, suggesting that human activity on Earth has little to no effect on lunar temperatures.

The Original Hypothesis

Last year, the theory proposed that as businesses and activities came to a halt during the pandemic, carbon emissions and terrestrial radiation dropped. Terrestrial radiation is the heat generated by our planet, which the Moon absorbs. Previous studies had hinted that Earth’s radiation might influence the Moon’s surface temperature, and there was an observed decrease in lunar nighttime temperatures from April to May 2020.

A Closer Look at the Data

Researchers from Missouri University of Science and Technology (Missouri S&T) and the University of West Indies (UWI) set out to verify the initial findings. Civil engineer William Schonberg from Missouri S&T says, “The idea that our activity, or lack thereof, on Earth would significantly influence the Moon’s temperature seemed unlikely, but we decided to investigate further.”

Identifying Flaws in the Original Study

The team identified several discrepancies in the original study’s hypothesis. They noted a similar dip in lunar temperatures in 2018, alongside a steady decline from 2019, which do not align with the timeline of the pandemic and its lockdown measures. The readings from NASA’s Lunar Reconnaissance Orbiter suggest cyclical fluctuations, rather than a single distinct dip, as previously suggested.

Further Insights

A 2021 study found that any reduction in emissions due to COVID-19 only affected the lower parts of Earth’s atmosphere, not the global climate or heat radiation reaching the Moon. Schonberg adds, “We’re not disputing that the temperatures dipped during the study period, but attributing this to human activity seems a bit of a stretch.”

Alternative Theories

Interestingly, the researchers also consider the possibility that a clearer night sky, resulting from reduced pollutants, might actually increase the heat reflected back from Earth to the Moon, potentially raising lunar temperatures. However, the influence of human activity on the Moon’s temperature remains minimal.

Conclusion

The research concludes that shifts in human activity, including those during global pandemics, are unlikely to have a notable impact on the Moon’s surface temperatures. Schonberg remarks, “During the Moon’s nighttime, there might be a small possibility that heat and radiation from Earth affect surface temperatures, but this influence would be too minimal to measure or observe.”

Final Thoughts

While the connection between human activities on Earth and lunar temperatures is fascinating, this new study underscores the complex factors influencing both planetary and lunar ecosystems. It also highlights the importance of rigorous scientific research in validating initial findings.

The implications of this research extend beyond our understanding of lunar temperatures. It reminds us to approach complex scientific questions with an open mind, relying on empirical evidence and thorough analysis.

The research has been published in the Monthly Notices of the Royal Astronomical Society: Letters.
