Boreholes on the Moon could solve climate puzzle

Here’s another reason to go back to the moon: it may help settle a climate change controversy. Climate modellers use ice cores, tree rings and sunspot data to see how much solar energy reached Earth centuries ago and whether it affected global temperatures. Such methods are far from reliable, though: sunspot data is incomplete, while conditions on Earth can skew results. Bob Cahalan at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and colleagues calculated that boreholes on the moon just 10 metres deep would provide a temperature record stretching back to the 1600s,
