The marine water temperature in May reached an all-time high

this Thursday, June 8th Is it World Oceans Daya conference promoted in 2008 by United Nations Organization (UN). the goal? “Report for Human impact on the oceandeveloping a global support movement and uniting residents in a project for Sustainable management of our seas“, according to the agency.

for the United Nations Excessive heat and force The ocean is warming change in temperature take some Unprecedented progressive effectsWhich includes bipolar meltinghe rising sea levels, marine heat waves And acidification from the ocean. These changes ultimately have a lasting impact on marine biodiversity and on the lives and livelihoods of coastal communities.”

only regarding ups and downs The temperature overboard, lately Copernicus Climate Change Servicefollower European UnionIt stated in a statement that the sea surface temperature and marine air temperature are average in all seas without ice, It reached its highest level in May, with 19.7°C“, regarding previous measurements made by the agency in the same period since 1979. At the same time, they explained that this indicator was”0.26°C above the 1991-2020 average″.

He warned, “Ocean surface temperatures are already at record levels and our data indicate that the average temperature of all ice-free seas in May 2023 was higher than in any other May.” Samantha BurgessDeputy Director of Copernicus.

He added: “Temperatures over the ocean may increase more in the coming months, because we see that as a signal El Niño phenomenon (LoE: characterized by volatility Temperatures And for changes in atmospheres) to emerge in the equatorial Pacific.

Secondly, the Copernicus Climate Change Service revealed this May 2023 was the second warmest May globally, less than 0.1 °C cooler than the warmest May on record. In addition, for the third time in 2023, it has been extended Antarctic sea ice value reached Monthly low record for the time of year within the satellite data record.

In turn, from the European Union Monitoring Service they cited data From Mercator Ocean International, a specialized organization that brings together oceanographers from Europe, which notes that, currently, “several regions such as the North Pacific, Southeast Pacific, North Atlantic, and areas near New Zealand and Australia are experiencing waves Moderate to extreme marine heat.As our climate continues to warm rapidly, New temperature records are set regularly“.

According to these specialists,Since early April 2023, the average ocean surface temperature has surpassed the previous record of 21 degrees Celsius (°C) set in 2016., reaching 21.1 degrees Celsius. This peak has passed and there are signs that temperatures are dropping again following the seasonal cycles.”

For the United Nations, “warming represents a Increased risk of irreversible loss of coastal and marine ecosystems. Today, an expansion of these changes has been observed, including damage to coral reefs and mangroves that help support ocean life, as well as migration of some species to higher latitudes and altitudes where the waters may be fresher.”

Year after year the organization reveals its concern about the impact of climate change on the oceans, since these “produce at least 50% of the planet’s oxygen, house most of the Earth’s biodiversity, and are the main source of protein for more than a billion people around the world.”

According to the European Union’s Climate Change Service, Antarctic ice reached a record low in May. In this context, a study was published in the journal a few weeks ago nature Be warned that the current conditions of El Niño can accelerate the melting of this ice.

After analyzing 31 climate models, researchers from Australian Government Science Agency Suppose that changes in “El Niño” could lead to a decrease in Temperature affiliate Surface of the water and increase in temperature water under water affiliate white continent. Wenju Cai, one of the paper’s authors, explained: “This new research shows that a more intense El Niño can accelerate the heating affiliate Antarctic shelf deep watercausing shelves and ice caps to appear dissolve faster“.

infobae Analyze the results of this study with Carlos Zotelograduated in Atmospheric Sciences from the Center for Renewable Natural Resources in the Semi-Arid Zone (CERZOS) in cone. “Should an El Niño intensify, this would translate not to a decrease in surface water temperature, but to a thermal increase in the deep submerged waters. This would cause Dissolution occurs from below, melting ice sheets from the ocean itself. in this way, A lot of ice will be lost, which usually freezes in winter and summerZotel said.

He added: “It’s still not clear if El Niño will actually intensify; you’ll have to wait a little bit longer, but if that’s the case, Antarctica’s waters will be much warmer.” Biodiversity in Antarctica (or anywhere) with significant environmental disturbances may suffer the consequences. Sometimes they are reversible, because they can be coursesBut in the specific case of the White Continent, the problem is that if the melting is permanent, many species can be affected.”

for his part, Alfredo Costaa graduate of biological sciences from the University of Buenos Aires (UBA), contributed: “The Antarctic Peninsula is the second region after the Arctic where the average temperature has increased the most in the last 60 years. Why does the temperature increase in the polar regions? By what is called polar amplification White roofs reflect solar radiation, and energy is released from the earth into space.Because of global warming, there are glaciers that have melted or frozen seas that have not frozen as before, so the white surface in the polar regions decreases and reflects less solar radiation and absorbs more This leads to an increase in the temperature of the planet and a feedback process is created that affects the polar regions more than other regions.”
