Between 1993 and 2018, the mean sea level has risen across most of the world ocean (blue colors). [71] Coastal ecosystems are facing further changes because of rising sea levels. Some ecosystems can move inland with the high-water mark, but others are prevented from migrating due to natural or artificial barriers.
Jack mackerel caught by a Chilean purse seiner Fishing down the food web. Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area.

The number of fish on the government's overfishing list sunk to a new low last year in a sign of healthy U.S. fisheries, federal officials said. The National Oceanic and Atmospheric Administration ...
By 2100, sea level in the Caribbean is expected to rise by 1.4 m. [23] Rise in sea level could impact coastal communities of the Caribbean if they are less than 3 metres (10 ft) above the sea. In Latin America and the Caribbean, it is expected that 29–32 million people may be affected by the sea level rise because they live below this threshold.
As the summer season gets underway, a new report finds that many coastal U.S. waterways, including popular beaches for swimming, are contaminated with unsafe levels of fecal bacteria.
Warmer, ice-free conditions in the southeast Bering Sea are roughly 200 times more likely now than before humans began burning planet-warming fossil fuels. Scientists have more evidence to explain ...
A sign on South Tarawa, Kiribati pointing out the threat of sea level rise to the island, with its highest point being only three metres above sea level.. The effects of climate change on small island countries are affecting people in coastal areas through sea level rise, increasing heavy rain events, tropical cyclones and storm surges.
