Acoustic Communication Among Sea Animals
The animals were sending messages all along, but humans had never thought to listen to them says Gabriel Jorgewich-Cohen, a PhD student at University of Zurich, Switzerland. He used sound and video equipment to record sounds made by 53 species in captivity around the world. It had been thought that these animals were mute but Mr Jorgewich-Cohen suggests they went unheard because their sounds were hard to detect. "Sea turtles will sing from within their egg to synchronize hatching," he explained. "If they call from inside, they all come out together and hopefully avoid being eaten."

USA Fish & Wildlife Service Lists Emperor Penguins as Endangered
As Antarctic sea ice is lost the birds featured in the film March of the Penguins face almost complete annihilation by end of century. The waters around and below the sea ice are important to the penguins as an area for feeding and the ice itself is essential as a place for the animals to rest, to shelter during their annual molt, and to escape from predators. But the loss of sea ice, due to global heating, threatens the habitat of these penguins and ocean acidification is diminishing the supply of krill, a key food source.

Factory Farm In Canary Islands Plans to Slaughter
1 Million Octopuses Every Year
Millions of animals are slaughtered in factory farms each year, and a new project threatens octopuses with the same fate. A Spanish company Nueva Pescanova has invested €65 million to build the world’s first commercial octopus farm in Las Palmas, Gran Canaria, Canary Islands. The company plans to supply the food and restaurant industry with 3,000 tons of octopuses annually, intending to slaughter about one million octopuses every year, starting in 2023. Previous efforts to farm octopus have struggled with high mortality, while attempts to breed wild-caught octopus ran into problems with aggression, cannibalism and self-mutilation.
Octopuses are intelligent, inquisitive and sensitive creatures. “It’s probable that the octopus’s reaction to pain is similar to a vertebrate. They can anticipate a painful, difficult, stressful situation and they remember it,” says Jennifer Mather, PhD, an expert in the behavior of octopus and squid at the University of Lethbridge in Alberta. “There is absolutely no doubt that they feel pain.” Typically [octopuses] are killed by clubbing, cutting into their brains without anesthetic, asphyxiation in a net, and freezing in ice. More gruesome methods include chemical overdose, decapitation, or electrocution. An octopus farm in the Canary Islands would condemn thousands of octopuses into a life of captivity and suffering.
Octopus farming also contravenes the EU Strategic Aquaculture Guidelines; the killing of other marine life caught to feed the octopuses further depletes fish populations and disrupts marine ecosystems.
Instead of slaughtering octopuses, many suggest that the company might find it more lucrative to provide interactions with these remarkable animals while educating the public how special they truly are.

Sea Level Rise in the Mediterranean
Scientists from the National Oceanography Centre have discovered a substantial rise in sea-levels in the Mediterranean Sea. The study indicate sea levels in the Mediterranean Sea have risen at significantly higher rates over the past 20 years compared to the entire of the 20th century. The study analyzed sea-level data from tide gauges and satellites and determined the increase was the result of ocean warming and land ice-melt. The methods used in the study may enable detection in acceleration in sea-level rise much earlier, allowing more time for coastal areas to adapt and protect his
“This is the first time we are able to clearly distinguish between natural variations in sea-level rise and changes arising from sustained human impact in the Mediterranean Sea, based on observations alone," said Dr. F. M. Calafat, one of the scientists and author of the study. "We have achieved this by analyzing data from tide gauges and satellite altimetry together with sea-level patterns of response to land-ice melting, which explains how sea-level rises thousands of miles away from melted land ice sheets.”

COP27
DATES: November 6 to 18, 2022
LOCATION: Sharm el-Sheikh, Egypt
COP27, the annual UN Climate Conference, will focus on three main areas: reducing emissions, helping countries to prepare and deal with climate change, and securing technical support and funding for developing countries for these activities.
Our planet is warming because of emissions produced by humans, mostly from burning fossil fuels like oil, gas and coal. UN climate summits are held every year at which governments agree on steps to limit the rise in global temperatures. Carbon dioxide emissions remain the biggest threat; they are the main drivers of climate change and associated extreme weather. They will continue to affect climate for thousands of years through polar ice loss, ocean warming and sea level rise.
