Moving The Moon

The first of my columns for The Engineer has appeared online. It’s about exploring different ways to use the Moon to help climate change on Earth. Some of these ways are more feasible than others…

However, if we could use giant motors or near misses by large asteroids to move the Moon closer to the Earth, we could maybe reset this process, using a faster-orbiting Moon to increase the Earth’s rotation and shorten our days. Why would we want to do that? Well, assuming we could withstand the resultant earthquakes and manage not to drop the entire Moon into the Pacific, the main effect of a shorter day would be that it would give the East and West hemispheres of the Earth less time to warm up in the glare of the Sun. The oceans would have less time to absorb heat, and winters would become colder. In addition, a faster-rotating Earth would give us faster-moving tides, which could have implications for tidal power generation – not to mention surfers.
