California coastal waters are acidifying

Oahu’s Hanauma Bay on Wednesday, May 6, 2016 near Honolulu. Much of the inner reef at Hanauma Bay is dead after decades of tourist interaction, but the outter reef is still relatively healthy. More than 2,000 international reef scientists, policymakers and stakeholders are gathering in Hawaii starting Monday, June 20, 2016, to discuss the latest coral science and what can be done to stop widespread death of the world's reefs.(AP Photo/Caleb Jones) (AP)

Global warming is likely playing a bigger role than previously thought in dead zones in waterways around the world and it’s only going to get worse, according to a new study.Dead zones occur in oceans, lakes and rivers when fertilizer runoff clog waterways with nutrients, such as nitrogen and phosphorous, which leads to an explosion of microbes that consumes oxygen and leaves the water starving for oxygen, harming marine life.

The release of carbon dioxide into the air from factory smokestacks to the tailpipe on your car could pose a risk to red king crab and other lucrative fisheries in Alaska, a new report says. The research, led by the National Oceanic and Atmospheric Administration, was to be published Tuesday, July 29, 2014, in the online journal Progress in Oceanography.
