caption_attribution_description: English: Line plot of global mean land-ocean temperature index, 1880 to present, with the base period 1951-1980. The black line is the annual mean and the red line is the five-year running mean. The green bars show uncertainty estimates. [This is an update of Fig. 1A in Hansen et al. (2006).] The graph shows an overall long-term warming trend.
context_page_description: Effects of global warming on oceans provides information on the various effects that global warming has on oceans. Global warming can affect sea levels, coastlines, ocean acidification, ocean currents, seawater, sea surface temperatures, tides, the sea floor, weather, and trigger several changes in ocean bio-geochemistry; all of these affect the functioning of a society.
