Small coincidence that over the past 50 years of global  industrialization, rising CO2 emissions have also led to a 30% increase in the average acidity of ocean surface water.

This phenomenon is just starting to attract the attention– and alarm– of policymakers and the shellfish industry.  I talked to Scott Doney and Sarah Cooley at WHOI to find out why.

Underwater camera shows climate change impact on fisheries

The effects of climate change are being felt in regional fisheries, causing a scientist at the Woods Hole Oceanographic Institution to predict that haddock will disappear from the North Atlantic within 70 years. A 3-D underwater camera helped confirm the numbers. (more…)
