The ocean is acidifying at the fastest rate

The latest research by UN and US scientists has confirmed that the world's oceans are currently acidified at the fastest rate of any time in the past 300 million years due to emissions. industry.

Lead research published on March 2, a reporter at the United Nations said oceans absorb carbon dioxide (CO ₂ ) in the atmosphere and form carbonic acid, reducing pH in seawater.

The pH of the oceans has dropped to 0.1 units in the last century, 10 times faster than the historic time 56 million years ago.

Research by the United Nations Intergovernmental Panel on Climate Change (IPCC) predicts that pH in world oceans could be reduced by another 0.3 units this century.

million years also associated with acidification of the oceans

The IPCC warns that although oceanic acidification is now similar to past events, no past events can be compared to future projections of scale and current speed of ocean acidification.

The rapid discharge of CO ₂ has never been seen in Earth's history, which imbalances the danger of carbonaceous chemicals in the oceans. The hottest temperature in the first 20,000 years of the 3rd era of the Earth has caused the pH of the oceans to decrease by 0.45 units.

Fossil records of this period indicate that more than 50% of unicellular organisms living on the ocean floor have become extinct and it is possible that many higher-level organisms in the food chain have also died mass .

Fossil records also confirm two other great extinctions 200 million years ago and 252 million years also associated with acidification of the oceans.

These studies warn that acidified oceans threaten the habitat of many marine species, especially krill, coral reefs and ocean salmon.

Scientists at Columbia University (USA) have attached a massive extinction of many species of marine life with high acidity in the sea, and warned many important species for humans are also under threat. serious if greenhouse gas emissions continue to be released into the atmosphere at the current rate.
