Scientists can now see the big picture on water globally — which areas are repeatedly drying and which are getting hammered by extra-strong rainstorms, thanks to new analysis of satellite data

Climate change and the impact on avalanche cycles
ABC News spoke with experts on how climate change and humans are causing an impact on avalanche seasons.
The intensity of extreme drought and rainfall has “sharply” increased over the past 20 years, according to a study published Monday in the journal Nature Water. These aren’t merely tough weather events, they are leading to extremes such as crop failure, infrastructure damage, even humanitarian crises and conflict.
The big picture on water comes from data from a pair of satellites known as GRACE, or Gravity Recovery and Climate Experiment, that were used to measure changes in Earth’s water storage — the sum of all the water on and in the land, including groundwater, surface water, ice, and snow.
“It’s incredible that we can now monitor the pulse of continental water from outer space,” said Park Williams, a bioclimatologist at the University of California, Los Angeles who was not involved with the study.
