The Blue Acceleration: Recent colossal rise in human pressure on ocean quantified

(Stockholm Resilience Centre) Human pressure on the world’s ocean accelerated sharply at the start of the 21st century and shows no sign of slowing, according to a comprehensive new analysis on the state of the ocean.Scientists have dubbed the dramatic rise the “Blue Acceleration”. The researchers from the Stockholm Resilience Centre, Stockholm University, synthesized 50-years of data from shipping, drilling, deep-sea mining, aquaculture, bioprospecting and much more. The results are published in the journal One Earth, 24 January.
