The world\u2019s oceans are facing a \u201ctriple threat\u201d of extreme heating, a loss of oxygen and acidification, with extreme conditions becoming far more intense in recent decades and placing enormous stress upon the planet\u2019s panoply of marine life, new research has found.<\/p>\n

About a fifth of the world\u2019s ocean surface is particularly vulnerable to the three threats hitting at once, spurred by human activity such as the burning of fossil fuels and deforestation, the study found. In the top 300 meters of affected ocean, these compound events now last three times longer and are six times more intense than they were in the early 1960s, the research states.<\/p>\n

The study\u2019s lead author warned that the world\u2019s oceans were already being pushed into an extreme new state because of the climate crisis. \u201cThe impacts of this have already been seen and felt,\u201d said Joel Wong, a researcher at ETH Zurich, who cited the well-known\u00a0example<\/a>\u00a0of the heat \u201cblob\u201d that has caused the die-off of marine life in the Pacific Ocean. \u201cIntense extreme events like these are likely to happen again in the future and will disrupt marine ecosystems and fisheries around the world,\u201d he added.<\/p>\n

The research,\u00a0published in AGU Advances<\/a>, analyzed occurrences of extreme heat, deoxygenation and acidification and found that such extreme events can last for as long as 30 days, with the tropics and the north Pacific particularly affected by the compounding threats.<\/p>\n
