2016 was another busy year in the Earth and space sciences.

We saw discoveries of gravitational waves and more exoplanets, dramatic changes in the Arctic, the successful orbit of Juno around Jupiter, and the coming into force of the Paris climate accord. The year also saw reductions in funding for state geological surveys, the first glimpse of solar wind formation, results of energy and environment issues on the ballots in the U.S. election, and the selection of the second consecutive geoscientist to head the U.S. National Academy of Sciences.
