  • Oceanic warming & acidification are accelerating hypoxia (which, as you may recall is being caused by agricultural and sewage runoff)
  • Decline of the ocean is as bad, or worse than the ‘doomsayers’ have been predicting
  • The cumulative effects are worse than previously understood
  • The cumulative stressors are reducing the ability of ocean life to adapt to the ‘big changes’ of warming & acidification
  • Ecosystem collapse is well underway, accelerating and spreading
  • We are running out of time to take useful action

But enough of this dreary talk!  Let’s go back to our ordinarily scheduled programming to cover more on Weiner’s weiner!

Scientists speculated that the higher levels of acid would affect the trillions of little critters at the base of the food chain that have calcium based shells or other protection, such as coral.  Sadly, a recent study confirms the adverse impact of higher acidity levels on ocean life.
