Título: Cómo se encuentra en 2023 la capa de ozono: lo que no sabías

La importancia de la ozonosfera para preservar la vida biológica en la Tierra es tal que, hace más de cuatro décadas, distintos organismos decidieron celebrar el 16 de septiembre el Día Internacional de la Preservación de la Capa de Ozono.

En química, el ozono se representa bajo la nomenclatura O3 debido a la cantidad de átomos de oxígeno que necesita para constituirse como tal, explica la NASA. 

Esta molécula relativamente inestable está formada por tres átomos de oxígeno y, aunque representa solo una pequeña fracción de la atmósfera, es crucial para la vida en la Tierra.

Cómo se encuentra la capa de ozono en el año 2023

“Está camino a recuperarse en las próximas cuatro décadas", indica un comunicado de la Organización Meteorológica Mundial (OMM) publicado el 9 enero de 2023. 

El documento destaca también la eliminación progresiva a escala mundial de las sustancias químicas que la agotan ya que contribuye a la mitigación del cambio climático.

Esa conclusión fue realizada por distintos expertos en meteorología que, respaldados por las Naciones Unidas, confirmaron que la eliminación progresiva de cerca del 99% de las sustancias prohibidas que agotan la capa de ozono ha logrado protegerla y ha contribuido a que se recupere de forma notable en la estratosfera. 

Además, esta medida mundial ha ayudado a disminuir la exposición de las personas a la radiación ultravioleta (UV) nociva del sol.

Las sustancias prohibidas son un conjunto de gases de efecto invernadero producidos por los humanos que dañan la capa de ozono. 

Entre ellos, la ONU incluye los clorofluorocarbonos, unas sustancias que se encuentran en los productos cotidianos como aparatos de aire acondicionado, frigoríficos y envases de aerosoles.

En tal sentido, si se mantienen las políticas de cuidado actuales, la capa de ozono recuperará los valores de 1980 (antes de la conformación del agujero de ozono) aproximadamente en 2066 en la Antártida, en 2045 en el Ártico y en 2040 en el resto del mundo, estiman los expertos de la OMM.

Title: How the ozone layer is in 2023: what you didn't know

The importance of the ozone layer in preserving biological life on Earth is such that, more than four decades ago, different organisms decided to celebrate the International Day for the Preservation of the Ozone Layer on September 16.

In chemistry, ozone is represented under the O3 nomenclature due to the number of oxygen atoms it needs to constitute itself as such, NASA explains.

This relatively unstable molecule is made up of three oxygen atoms and, although it makes up only a small fraction of the atmosphere, it is crucial for life on Earth.

"It is on track to recover in the next four decades," says a statement from the World Meteorological Organization (WMO) published on January 9, 2023.

The document also highlights the global phasing out of chemicals that deplete it as it contributes to climate change mitigation.

That conclusion was made by different meteorological experts who, supported by the United Nations, confirmed that the progressive elimination of about 99% of the prohibited substances that deplete the ozone layer has managed to protect it and has contributed to its remarkable recovery in the stratosphere.

In addition, this global measure has helped decrease people's exposure to harmful ultraviolet (UV) radiation from the sun.

Prohibited substances are a set of human-produced greenhouse gases that damage the ozone layer.

Among them, the UN includes chlorofluorocarbons, substances found in everyday products such as air conditioners, refrigerators and aerosol containers.

In this sense, if current care policies are maintained, the ozone layer will recover to 1980 values (before the formation of the ozone hole) by approximately 2066 in Antarctica, 2045 in the Arctic and 2040 in the rest of the world, WMO experts estimate.

This relatively unstable molecule is made up of three oxygen atoms and, although it represents only a small fraction of the atmosphere, it is crucial for life on Earth.

"It is on track to recover over the next four decades," states a World Meteorological Organization (WMO) communiqué released on January 9, 2023. The document also highlights the global phase-out of depleting chemicals as it contributes to climate change mitigation.

This conclusion was made by various meteorological experts who, backed by the United Nations, confirmed that the progressive elimination of nearly 99% of banned ozone-depleting substances has succeeded in protecting the ozone layer and has contributed to its remarkable recovery in the stratosphere. In addition, this global measure has helped to reduce people's exposure to harmful ultraviolet (UV) radiation from the sun.

Banned substances are a group of human-produced greenhouse gases that damage the ozone layer. Among them, the UN includes chlorofluorocarbons, substances found in everyday products such as air conditioners, refrigerators and aerosol containers.

In this sense, if current care policies are maintained, the ozone layer will recover its 1980 values (before the formation of the ozone hole) approximately in 2066 in the Antarctic, in 2045 in the Arctic and in 2040 in the rest of the world, according to WMO experts.
