Freshwater is disappearing from the Earth at alarming rates: Study

NORTHERN HEMISPHERE, JUL 28 – The study identifies four vast Northern Hemisphere drying zones expanding by over 321,000 square miles annually, driven by climate change and groundwater depletion, threatening water and food security.

  • On Friday, Arizona State University-led researchers published a study in Science Advances, revealing Earth’s freshwater is declining faster than ever based on over 22 years of satellite data.
  • Using more than 20 years of satellite data from GRACE and GRACE-FO, researchers warn that Earth's continents have experienced unprecedented freshwater loss, accelerating after 2014.
  • Groundwater pumping by farmers, cities and corporations now accounts for 68% of freshwater loss, with drying regions expanding by about 831,600 km² annually, researchers warn.
  • Amid shifting water distribution, Jay Famiglietti warned billions could face food and water security threats as freshwater loss significantly contributes to sea level rise.
  • Researchers warn, 'These findings send perhaps the most alarming message yet about the impact of climate change on our water resources,' urging stronger data collection and international cooperation.
