Sardines are up to two thirds SMALLER now than 12 years ago due to climate change

Sardines are up to two thirds smaller now than 12 years ago, since the warming of water caused by climate change is killing the plankton they feed on.

Researchers at the French Ifremer Oceanographic Institute have been studying the sizes of sardines in the Mediterranean Sea and the Bay of Biscay in the Atlantic.

While the former has seen the largest reduction in average sizes, the team reports that Atlantic sardines have also lost about half of their weight a decade ago.

Changing populations of sardines are having side effects, the team also noted, and other species such as cod and seabirds are also suffering.

Ifremer researchers have been studying the state of sardines in the Mediterranean since 2008, after fishermen drew their attention to the contraction.

During this time, Mediterranean sardines have been reduced from an average length of 5.1 inches (13 cm) to 3.9 inches (10 cm) last year, while their counterparts in the Bay of Biscay have gone from around 7.1 (18 cm) to 5.5 (14). cm).

The team's analysis has ruled out predation, overfishing and disease as the cause of these changes in sardine populations, and climate change is likely to be blamed.

"For sardines and anchovies in the Bay of Biscay and in the Gulf of León (in the Mediterranean), we are leaning towards environmental factors related to the increase in temperature and the decrease in the amount of food available," said the biologist Clara Ulrich

Sardines feed on microscopic plankton, a food source that has become less healthy with rising sea surface temperatures.

The problem is that the nutrients that feed the plankton are not increasing from the colder deep waters as they did before, the researchers explained.

In addition to reducing their size, the decline in food stocks also seems to be reducing the shelf life of sardines, which has declined from three years ago a decade to just one year today.

"It is very alarming to see such damaged fish," the president of the Institute of the Sea Foundation, Sabine Roux de Bézieux, told Europe 1 radio, that the recently published findings are a crisis.

"It is a sign of the very poor health of the surrounding environment."

"This should alert us to the disaster that is occurring in the oceans due to climate change."

Experts also report that sardines are shrinking higher in their food chain, and their predators, particularly seabirds, no longer receive the same levels of food they used to enjoy.

However, cascade contraction is not confirmed in the Mediterranean and the Atlantic; Similar trends have been observed in the Baltic Sea, the Indian Ocean and the Pacific Ocean off the coast of South America.

"The Baltic cod has become so thin that they look like sardines," Ulrich said.

Meanwhile, off the coast of the Galapagos Islands, Nazca boobies have changed their diet preference in the last ten years of sardines to flying fish less rich in nutrients in response to the decrease in the number of sardines.

According to the researchers, the fish may have moved to colder waters and, therefore, could disappear completely from the entire archipelago within a century if ocean temperatures continue to rise incessantly.

According to the researchers, the fish around the Galapagos Islands may have moved to colder waters and, therefore, could disappear completely from the entire archipelago in the century if ocean temperatures continue to rise incessantly.

However, there was some good news in the results of the latest Ifremer survey.

Researchers have discovered that, following the drastic restrictions imposed on the catch sizes of fishing vessels, bluefin tuna populations in both the Atlantic and the Mediterranean are growing healthy again.

Despite this, about a quarter of the fish caught by French ships belong to species that are currently threatened by overfishing, such as sardines in the Bay of Biscay, haddock in the Irish Sea and cod in the Northeast Channel and the Irish Sea.

"TIME IS OVER": DAVID ATTENBOROUGH WARNING TO HUMANITY

Sir David urged action against global warming and called it a man-made disaster that represents "our greatest threat in thousands of years."

Sir David urged action against global warming and called it a man-made disaster that represents "our greatest threat in thousands of years."

Sir David urged action against global warming and called it a man-made disaster that represents "our greatest threat in thousands of years."

Your excellencies, ladies and gentlemen.

& # 39; We the peoples of the United Nations & # 39 ;.

These are the initial words of the Charter of the United Nations.

A letter that puts people in the center.

A promise to give every person in the world a voice about their future.

A promise to help protect the weakest and strongest from war, hunger and other man-made disasters.

At this time, we are facing a man-made disaster on a global scale.

Our biggest threat in thousands of years. Climate change.

If we don't take action, the collapse of our civilizations and the extinction of much of the natural world is on the horizon.

The United Nations provides a unique platform that can unite the entire world.

And as the Paris agreement demonstrated, together we can achieve real change.

At this crucial moment, the United Nations has invited the people of the world to hear their voice, giving them a seat.

The seat of the people; giving everyone the opportunity to join us here today, virtually, and speak directly with you decision makers.

In the last two weeks, the people of the world have participated in the construction of this address, answering surveys, sending video messages and expressing their opinions.

I'm only here to represent the & # 39; Voice of the people & # 39 ;: to convey our thoughts, concerns, ideas and collective suggestions.

This is our message "We the peoples."

The people of the world have spoken. Your message is clear.

Time is running out.

They want you, the decision makers, to act now.

They are behind you, along with the civil society represented here today.

Supporting you in making difficult decisions, but also willing to make sacrifices in your daily life.

To help change happen, the UN is launching the Act Now bot.

Help people discover simple everyday actions they can take, because they recognize that they must also play their part.

The people have spoken.

Leaders of the world, you must lead.

The continuation of our civilizations and the natural world we depend on is in your hands.
