]]> this is a podcast that includes audio from an interview that i completed with an esteemed fisheries scientist at suny esf, dr. neil ringler. the podcast discusses the history/cultural significance of atlantic salmon, incentives to reintroduce, implications to existing fisheries, barriers to reintroduction, dr. ringler’s vision, restoration on behalf of native americans, dr. ringler’s current assessment of the fisheries, and the role of anglers in reintroduction.

scientists believe abrupt changes in the atlantic meridonial overturning circulation, the dominant north-south ocean circulation current in the atlantic, caused the observed abrupt climate changes in the north atlantic. climate modelers from oregon state university have modeled an episode of abrupt climate change that shows remarkable agreement with observed concentrations of greenhouse gases. they concluded that ocean circulation changes were primarily responsible for driving co2 and nitrous oxide fluctuations during glacial periods on millennial time scales.

ultimately, the model’s agreement with ice core sample evidence lends credibility to the hypothesis that ocean circulation modulates variations in greenhouse gases. this knowledge may also help scientists postulate a solution for climate change.
