The seas have long sustained human life, but a new study shows that rising climate and human pressures are pushing the oceans towards a dangerous threshold. The future of our oceans is worrying, according to researchers at UCSB’s National Center for Ecological Analysis and Synthesis (NCEAS). “Our cumulative impact on the oceans, which is already substantial, is going to double by 2050,” said marine ecologist and NCEAS director Ben Halpern, who led the effort to forecast the future state of marine environments as they bow under the combined pressures of human activities, which include ocean warming, fisheries biomass loss, sea level rise, acidification and nutrient pollution, among other impacts.
