Oceans are undergoing “unprecedented changes” as a result of global warming, according to a new report.
According to a recently published research by more than 150 scientists, human-induced global warming is creating “unprecedented changes” in the oceans, including warming waters, diminishing ice levels, and rising seas.
The annual Ocean State Report 5 by the Copernicus Marine Service and Mercator Ocean International, which was released on Wednesday, is a comprehensive assessment of the health of the world’s oceans.
Since 1993, worldwide sea temperatures have been rising at a pace of 0.015 degrees Celsius each year, according to a study published in the Journal of Operational Oceanography. Meanwhile, since 1979, Arctic ice levels have fallen by about 13% every decade, with record lows in the previous two years.
Sea levels have risen by 3.1 mm per year as a result of warming waters and ice melting, with the Baltic Sea having the most annual growth at 4.5 mm per year.
In a press release, Karina von Schuckmann, oceanographer at the Copernicus Marine Service and chair of the report, said, “Climate change, pollution, and overexploitation have placed unprecedented pressure on the ocean, which not only covers 71 percent of the Earth’s surface but is also responsible for regulating Earth’s climate and sustaining life.”
The paper went on to say that the Artic Ocean was responsible for about 4% of the world’s ocean warming.
Most marine species are moving deeper toward the poles as a result of the global warming, while warm water species are expanding to new locations and becoming invasive, according to the report.
The report’s summary stated, “As a result of climate change, ocean warming is one of the key variables influencing marine species, generating altered circumstances for fisheries with societal and economic implications.” “With warming, hundreds of species have been observed migrating to higher elevations and greater depths.”
The paper focused on the effects of the world’s changing waters on Venice, Italy, which saw four consecutive extreme water occurrences in November 2019, primarily due to a higher-than-average sea level.
According to the report, on November 12 of that year, water levels reached 6.2 feet, the highest since 1966, leaving the city unprepared.
