Gases de Efecto Invernadero alcanzan niveles récord, advierte la OMM

La Organización Meteorológica Mundial (OMM) informó que los gases de efecto invernadero han alcanzado niveles históricos en 2022, con una concentración promedio mundial de dióxido de carbono (CO2) un 50% superior al nivel preindustrial.

Según el último informe de la ONU, las concentraciones de CO2 continúan su crecimiento sin indicios de reversión, al igual que las de metano, con el óxido nitroso experimentando el mayor aumento interanual entre 2021 y 2022.

El secretario general de la OMM, Petteri Taalas, expresó su preocupación por la persistencia de esta tendencia, indicando que el mundo se encamina hacia un aumento de temperaturas mucho más allá de los objetivos establecidos en el Acuerdo de París. Taalas subrayó las consecuencias previstas, como eventos climáticos extremos, derretimiento de hielo, aumento del nivel del mar y acidificación de los océanos.

Afirmó que es imperativo reducir urgentemente el consumo de combustibles fósiles para mitigar los impactos socioeconómicos y ambientales.

El estudio revela que el CO2, responsable del 64% del calentamiento, proviene principalmente de la quema de combustibles fósiles y la producción de cemento; y persistirá durante décadas, incluso si se reducen rápidamente las emisiones.

La OMM enfatiza la importancia de la Vigilancia Mundial de Gases de Efecto Invernadero para comprender mejor los factores del cambio climático y establecer objetivos más ambiciosos. Además, destaca que la gestión eficiente de vertederos podría captar el metano como fuente de combustible limpio y reducir riesgos para la salud.
