CryogenicKeen writes with the news that a University of Michigan study indicates the perfect place to monitor Earth's climate system would be the surface of the moon. The side facing us is a perfect location to monitor temperatures and weather patterns here on our planet, and a UM paper proposes an international effort to deploy monitoring stations on Earth's natural satellite. "On the near side of the airless moon, where Apollo 15 landed, surface temperature is controlled by solar radiation during daytime and energy radiated from Earth at night. Huang showed that due to an amplifying effect, even weak radiation from Earth produces measurable temperature changes in the regolith. Further, his revisit of the data revealed distinctly different characteristics in daytime and nighttime lunar surface temperature variations. This allowed him to uncover a lunar night-time warming trend from mid-1972 to late 1975, which was consistent with a global dimming of Earth that occurred over the same period and was due to a general decrease of sunlight over land surfaces."
