A. Carbon dioxide levels are increasing in the air, and the ocean is absorbing carbon dioxide; atmospheric levels are increasing so much that the increase is still apparent even with increasing absorption of carbon dioxide by the ocean. Research conducted by the University of Miami (UM) has found that the waters of the North Atlantic absorbed 50 percent more carbon dioxide of human origin in the last ten years than in the past decade.
The results of the study show the impact that the burning of fossil fuels has had on the world's oceans in the last ten years
