• stats

  • None of the 28 streams Cunningham and his colleagues studied hit summertime highs warmer than 25.9 C,
  • the point where warming water can become lethal.
  • But in four rivers, temperatures climbed past 20.3 C,
    • the threshold where some have found juvenile coho stop growing.
  • In some watersheds, deforestation rates climbed to 59 per cent.

• comment

  • deforestation may be a contributing factor but there are also other variables like changes in glacial melt water
