  • A satellite-AI study finds rising temperatures lower dissolved oxygen in rivers worldwide.
  • Qi Guan (research lead) measured oxygen in over 21,000 rivers since 1985, reporting an average 2.1% decline.
  • The analysis projects a further 4% drop by 2100, 5% in some systems, with warmer water causing about 63% of the loss.
  • Scientists warn reduced oxygen could create dead zones in the Eastern United States, India, the Amazon and tropical rivers.
