Areas outlined in black indicate where trends showed strong associations with human activities. Trends are depicted in terms of average annual change in equivalent water depth. NASA Earth Observatory/Michala Garrison, based on data from O’Neill, M.M., et al. Humans are exerting increasing influence over how water moves through lakes, rivers, soil, and the subsurface, and a new NASA study shows where those effects are greatest. Using more than two decades of satellite measurements of subtle changes in Earth’s gravity, the researchers sharpened the pi
