Tonight, in a special 90-minute live event ([link removed]) , the PBS NewsHour explores the connections between climate change ([link removed]) , warming oceans, migrating fish populations, the economic stressors facing the fishing industry, bad actors on the high seas, and ever-growing seafood demand.

Miles O’Brien ([link removed]) , Emmy Award-winning science journalist and Tipping Point ([link removed]) executive producer, will guide us through a conversation with a number of thought leaders for meaningful dialogue on the science, policy challenges and possible solutions.

As our world surges toward a global population of 9.9 billion by the year 2050, the need to feed all those people is spiking too, and that’s putting unprecedented stress on our fisheries. The UN Food and Agriculture Organization indicates that already “58% of the world’s fish stocks are being fished at or beyond sustainable levels.”

Climate change will only exacerbate the problem – warming waters are already forcing fish populations to migrate toward cooler habitats. A recent paper in the journal Science calculates that rising seawater temperatures will leach oxygen out of the seawater at increasingly dangerous levels. If we don’t manage to significantly curb greenhouse gas emissions immediately, marine animals will face a mass extinction within 300 years.
