Fisherman Randy Slavich drags a clunky metal net through an underwater oyster bed in Lake Machias, a brackish body opening into the Gulf of Mexico. For generations, this has been a bountiful lake for harvesting oysters, long before millions of… Read More ›
Studies show that red king crab and tanner crab, two important Alaskan fisheries, grow more slowly and don’t survive as well in more acidic waters. Alaska’s coastal waters are particularly vulnerable to ocean acidification because of cold water that can absorb more carbon dioxide, and unique ocean circulation patterns which bring naturally acidic deep ocean waters to the surface.
Today, experts predict pH declines in the world’s oceans of .4 units by the end of this century—a mere 85 years from now.
The oceans absorb over a quarter of the carbon dioxide in the atmosphere. The more we pollute, the more they absorb, and the more acidic they become. It’s unlikely that some marine life that we depend on will be able to adapt to a rate of acidification that is over ten times as fast as during the PETM.
