‘Ticket Time Bomb’: Marine acidity reached critical levels, threatened all ecosystems – work | Ocean acidification
Scientists said the world’s oceans are in health than worse than the occurrence.
The ocean acidification of the climate crisis, which is generally called “bad twin ,, causes when the carbon dioxide is rapidly absorbed by the ocean, when it reacts with water molecules that cause a decrease in the pH level of sea water. It damages coral reefs and other ocean habitats and can solve the shells of marine organisms in extreme cases.
Until now, ocean acidification has not been accepted that it has passed the “planetary border .. Planet borders are the natural boundaries of lock global systems such as climate, water and diversity of wildlife, where their ability to maintain a healthy planet is in danger of failure. Scientists said last year six of the nine had already passed.
But, A new study He found that the “boundaries ın of the Ocean Acidization of the Ocean Acidization of the Ocean Acidization of the Institute of Naval Resources Studies of the National Ocean and Atmospheric Administration of Washington and Oregon State University of Oregon, based by the Plymouth Sea Laboratory of England (PML).
Prof Steve Widdicombe, who is also a co-chairman of the PML, said, “Ocean acidification is not only an environmental crisis-a time bomb for ecosystems and coastal economies.” Global Ocean Acidization Observation Network.
The study was drawn on new and historical physical and chemical measurements from the ice seeds, merged with advanced computer models and sea life studies, which gave scientists a general assessment of the last 150 years.
Until 2020, the worldwide average ocean situation was already very close to the planetary border for ocean acidification and very close in some regions. This is defined as calcium carbonate concentration in sea water when industrial levels are more than 20%.
Scientists said how deep they looked in the ocean, the more the findings were so bad. 200 meters below the surface, 60% of global waters violated the “safe” limit for acidifying.
“Most of the ocean life doesn’t just live on the surface, Prof Prof Helen Findlay from PML said. “The following waters are home to different plant and animal species. This deeper waters can be much worse than we think about the effects of ocean acidification.”
This has added great effects for important underwater ecosystems such as tropical and even deep sea coral reefs that provide basic habitats and nursery areas for young people of many species.
As pH levels decrease, calcification species such as corals, oyster, mussels and small molluscs known as sea butterflies lead to weaker shells, slow growth, decreased reproductive and survival rates by struggling to protect their protective structures.
The authors underlined the diminishing CO2 Emissions were the only way to cope globally with acidification, but that protection measures should focus on and focus on the most vulnerable regions and species.
Jessie Turner, International Alliance Director to combat the ocean acidification, which is not included in the study, said: “This report clearly demonstrates this: no time and what we do – or we cannot do – now determines our future.
“While we are struggling with the difficult reality where the very suitable habitat is already disappeared for the key species, we agree with an existential threat. It is clear that governments can no longer ignore acidification in the mainstream policy agenda,” he said.
