According to new research, up to 95 percent of Earth's ocean surface would be altered by the end of the century unless humanity reduces carbon emissions.

The Hyperion Water Reclamation Plant, a sewage treatment plant on Santa Monica Bay, was forced to release untreated sewage via a conduit that deposited it a mile (1.6 kilometers) offshore and barely 50 feet (15.2 meters) below the ocean s surface on Sunday, according to operators. (The plant s standard pipe dumps treated sewage into the ocean five miles [eight kilometers] offshore and 190 feet [58 meters] deep.) According to a Hyperion spokesman, it was the most sewage discharged out of that single small pipe in a decade. According to the plant s managers, the leak accounted for just 6% of the plant s daily sewage load.

According to Pippa Moore, a marine-community ecologist at Newcastle University in the United Kingdom, the effects of marine heatwaves will reverberate up the food chain. Phytoplankton development was harmed by warm, low-nutrient water in the Northwest Pacific during The Blob, a coastal heatwave from 2013 to 2016. Then the population of Chinook salmon (Oncorhynchus tshawytscha) plummeted, and up to one million seabirds died in the Gulf of Alaska. For the last few decades, large quantities of coral bleaching have occurred in reefs worldwide due to marine heatwaves.
In 2013, a massive marine heatwave known as The Blob formed off the western coast of North America and lasted until the middle of 2016. From 2003 to 2012, this chart depicts satellite readings of ocean surface temperatures, with colors showing values that are higher (red) or lower (blue) than the average. The slider compares April 2014 temperatures to Mar

Researchers at the Scripps Institution of Oceanography at the University of California, San Diego, collected 27,345 barrel-like photographs. They surveyed over 36,000 acres of the seafloor between Santa Catalina Island and the Los Angeles peninsula, in an area where elevated levels of the toxic chemical had previously been discovered in sediments and the environment.

Before 1972, when the Marine Protection, Research, and Sanctuaries Act, also known as the Ocean Dumping Act, was passed, historical shipping records indicate that mining industries in southern California used the basin as a dumping area.

An analysis of nearly 50,000 aquatic species shifting positions between 1955 and 2015 showed that a projected effect of global warming - species moving away from the equator - can now be seen on a worldwide scale.

It said that more global warming, which is now imminent, would further reduce the diversity of biodiversity in tropical oceans.
The results of the change, according to scientists, may be dramatic and difficult to foresee.
Unpredictable Changes
According to Prof David Schoeman, a co-author of the report, species attached to the ocean floor had not diminished. Still, the diversity of free-swimming species such as fish had decreased dramatically between 1965 and 2010.
