Según los investigadores del Instituto Goddard de Estudios Espaciales (GISS, por sus siglas en inglés) de la NASA, en Nueva York, julio de 2023 fue el mes más caluroso de todos los que se han registrado en el registro de temperaturas mundiales.

“Desde su primer día [en la oficina], el presidente Biden ha tratado la crisis climática como la amenaza existencial de nuestro tiempo”, ha declarado Ali Zaidi, asesor nacional de la Casa Blanca en materia de clima. “Con el telón de fondo de las altas temperaturas, los incendios forestales y las inundaciones sin precedentes, el análisis de la NASA pone en contexto la urgencia del liderazgo sin precedentes del presidente Biden en materia de clima”. Desde la aprobación de la Ley de Reducción de la Inflación, la mayor inversión climática de la historia, hasta la invocación de la Ley de Producción de Defensa para impulsar la producción nacional de energía limpia, pasando por el refuerzo de la resistencia climática en comunidades de todo el país, el presidente Biden está cumpliendo la agenda climática más ambiciosa de la historia”.

En su conjunto, julio de 2023 fue 1,1 grados centígrados (2,09 F) más cálido que el julio promedio entre 1951 y 1980. El análisis de GISS se centra principalmente en los cambios de temperatura a largo plazo durante décadas y siglos, y un periodo base fijo produce anomalías coherentes a lo largo del tiempo. Las temperaturas “normales” se definen por varias décadas o más, normalmente 30 años.

“Los datos de la NASA confirman lo que miles de millones de personas en todo el mundo, literalmente, han sentido: las temperaturas de julio de 2023 lo convirtieron en el mes más caluroso que se haya registrado. En cada rincón del país, los estadounidenses están experimentando de primera mano los efectos del cambio climático, lo que subraya la urgencia de la histórica agenda climática del presidente Biden”, dijo el administrador de la NASA, Bill Nelson. “La ciencia es clara. Debemos actuar ahora para proteger nuestro planeta; es el único que tenemos”.

Algunos lugares de Sudamérica, África del Norte, América del Norte y la Península Antártica han sido especialmente calurosos y experimentaron aumentos de temperatura de unos cuatro grados centígrados (7,2 grados Fahrenheit). En general, el calor extremo de este verano ha puesto bajo alertas térmicas a decenas de millones de personas y se ha vinculado a cientos de enfermedades y muertes relacionadas con el calor. El récord de julio continúa una tendencia a largo plazo de calentamiento causado por las actividades humanas e impulsado principalmente por las emisiones de gases de efecto invernadero que se ha hecho evidente en las últimas cuatro décadas. Según datos de la NASA, los cinco julios más calurosos desde 1880 se han producido en los últimos cinco años.

“El cambio climático está afectando a la gente y a los ecosistemas de todo el mundo, y esperamos que muchos de estos impactos se intensifiquen con el calentamiento continuado”, dijo Katherine Calvin, científica jefe y asesora principal sobre el clima en la sede de la NASA en Washington. “Nuestra agencia observa el cambio climático, sus impactos y sus agentes impulsores, como los gases de efecto invernadero, y nos comprometemos a proporcionar esta información para ayudar a la gente a planificar el futuro.”

La NASA elabora su registro de temperaturas a partir de datos sobre la temperatura del aire en superficie procedentes de decenas de miles de estaciones meteorológicas, así como de datos sobre la temperatura de la superficie del mar obtenidos por instrumentos instalados en barcos y boyas. Estos datos en bruto se analizan mediante métodos que tienen en cuenta el espaciado variable de las estaciones de temperatura en el planeta y los efectos del calentamiento urbano que podrían sesgar los cálculos.

“Este mes de julio no sólo ha sido más cálido que los otros meses de julio anteriores, sino que ha sido el mes más cálido de todos nuestros registros, que se remontan a 1880”, declaró Gavin Schmidt, director del GISS. “La ciencia deja claro que esto no es normal. El alarmante calentamiento del planeta se debe principalmente a las emisiones de gases de efecto invernadero de origen humano. Y ese aumento de las temperaturas medias está impulsando el peligroso calor extremo que la gente está experimentando aquí y en todo el mundo.”

Las altas temperaturas de la superficie del mar contribuyeron al récord de calor de julio. El análisis de la NASA muestra temperaturas oceánicas especialmente cálidas en el Pacífico tropical oriental, lo que evidencia el fenómeno de El Niño que comenzó a desarrollarse en mayo de 2023. Fenómenos como El Niño o La Niña, que calientan o enfrían el Océano Pacífico tropical, pueden contribuir en pequeña medida a la variabilidad interanual de las temperaturas globales. Sin embargo, estas contribuciones no suelen notarse cuando El Niño comienza a desarrollarse en el verano del hemisferio norte. La NASA espera ver los mayores impactos de El Niño en febrero, marzo y abril de 2024.
