The Earth’s climate has hit a historic high, with 2023 marking the warmest year on record.
According to NASA’s analysis, global temperatures soared to about 2.1 degrees Fahrenheit (1.2 degrees Celsius) above the 20th-century average, spotlighting the relentless pace of the climate crisis.
This surge in temperatures has been felt worldwide, manifesting in extreme weather events from unprecedented heatwaves to devastating wildfires and rising sea levels.
NASA Administrator Bill Nelson emphasized the tangible impacts of the climate crisis, witnessed by billions globally, and highlighted the efforts of President Biden and communities across America to combat these challenges.
The administration, with NASA’s support, aims to bolster resilience against climate risks and enhance the planet’s health for future generations.
From June to December of 2023, each month shattered global temperature records, with July becoming the hottest month ever documented.
The year’s average temperature was significantly higher than the late 19th-century baseline, indicating a drastic shift in Earth’s climate.
Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies, attributed this unprecedented warming primarily to fossil fuel emissions, which have amplified the frequency and intensity of extreme weather phenomena.
Despite the natural climate variability influenced by events such as El Niño and La Niña, and occasional cooling factors like volcanic eruptions or aerosols, the long-term warming trend remains overwhelmingly driven by human activity.
The transition from La Niña to El Niño in May 2023 is noted as a contributing factor to last year’s record temperatures, with the peak effects of El Niño anticipated in the early months of the following year.
NASA’s findings underscore the critical need for immediate and sustained action to mitigate climate change.
The U.S. government’s recent climate investment, the largest in history, aims to fortify the nation’s resilience to the escalating impacts of the climate crisis.
NASA, through its extensive fleet of Earth-observing satellites, continues to play a pivotal role in monitoring our changing planet, providing invaluable data to inform policy and public awareness.
