A recent study found that the COVID-19 lockdowns in 2020 caused the Moon’s surface to cool by 8-10 degrees Kelvin. Researchers believe this happened because the lockdowns reduced human activity, leading to fewer greenhouse gas emissions and less heat being trapped in Earth's atmosphere. As a result, less radiation from Earth reached the Moon, causing its surface to cool. This surprising discovery shows how changes on Earth can affect even the Moon. More research is needed to confirm this link.
