This story from NPR, Acid in the Oceans, talks about the potential impacts of CO2 on the ocean and how it will affect marine life. Local scientists are doing some great work on this.
“It’s too early to say, just yet, what this portends for life at sea — up to and including the fat and happy sea lions down on the dock.” Peter Harris, Acid In the Oceans; A Growing Threat for Sea Life
As of yet, no one knows how this will affect sea otters. My hunch is, it won’t help. The clearest impact is a subtle but potentially significant “energy tax” that acidification puts on marine animals. Outside of their optimal conditions, it just takes more energy for critters to do the things they need to do to survive, such as forage or hunt, stay affloat, etc. Given that sea otters already seem to be taxed due to water quality concerns, I wonder what increased affect this might have.
