NASA Explores Our Changing Freshwater World – Climate Change: Vital Signs of the Planet

Over the next few weeks, we'll be exploring areas of NASA research into Earth's fresh water and surveying how those advances help people solve real world problems. On the ground, fresh water is stored in ice, snow, rivers and lakes. From space, NASA satellites track global precipitation and soil moisture, which allows scientists to track how rainfall can affect vegetation health around the globe.

In addition to witnessing the effects of agriculture, the satellite data show the effects of climate change, most notably in the decline of sea ice and ice sheets at the poles.
