NASA's latest analysis reveals that 2023 marked Earth's warmest year on record, with temperatures soaring 2.1 degrees Fahrenheit (1.2 degrees Celsius) above the 1951-1980 baseline. Extreme heat and global records each month from June to December emphasize the climate crisis. Despite occasional cooling factors like volcanic aerosols, the relentless rise is driven by greenhouse gas emissions. The report urges urgent action, aligning with NASA's commitment to providing critical climate data and supporting the Biden-Harris Administration's climate initiatives.


In the planetary theater of climate, Earth took center stage in 2023, setting a disconcerting record as the warmest year ever recorded. NASA's Goddard Institute for Space Studies (GISS) in New York unveils a stark reality: temperatures in 2023 soared 2.1 degrees Fahrenheit (1.2 degrees Celsius) above the baseline average from 1951 to 1980.

The global temperature report echoes the collective experience of billions worldwide, emphasizing the stark reality of a climate crisis. NASA Administrator Bill Nelson notes the palpable impacts, from rising sea levels to devastating wildfires, underlining the urgency for decisive action. The Biden-Harris Administration's commitment to climate resilience aligns with NASA's role in delivering accessible climate data.

2023 witnessed extreme heat gripping millions across the globe, with each month from June through December setting global records. July, in particular, etched its name as the hottest month ever recorded. The cumulative effect paints a worrisome picture, with Earth being approximately 2.5 degrees Fahrenheit (1.4 degrees Celsius) warmer than the late 19th-century average.

Gavin Schmidt, Director of GISS, emphasizes the unprecedented nature of the warming, primarily attributed to human activities like fossil fuel emissions. The impact manifests in heatwaves, intense rainfall, and coastal flooding. The report underscores the undeniable link between the ongoing climate crisis and human-induced global warming.

While phenomena like El Niño can influence yearly climate variations, the record temperatures in the latter half of 2023 occurred before the peak of the El Niño event. Scientists anticipate the full impact of El Niño in the coming months, highlighting the need for continued vigilance in monitoring climate trends.

The eruption of the Hunga Tonga-Hunga Ha’apai undersea volcano in January 2022 raised questions about potential cooling effects. However, a study revealed a minimal cooling impact of less than 0.2 degrees Fahrenheit (0.1 degrees Celsius) in the Southern Hemisphere. This emphasizes that, even with occasional cooling factors, the upward trajectory of global temperatures persists.

The record-setting warmth in 2023 adds to a concerning trend, marking the warmest year since modern record-keeping began in 1880. The past decade has consistently ranked as the warmest, emphasizing the long-term impact of climate change on our planet.

Deputy Administrator Pam Melroy highlights NASA's commitment to ongoing climate actions. NASA's Earth observing satellites play a crucial role in providing data to aid decision-making. The recently launched U.S. Greenhouse Gas Center further enhances collaboration to make climate-related data accessible to all.


The record-breaking warmth of 2023 serves as an urgent call to confront the climate crisis. Earth's rising temperatures, driven by human activities, demand swift and decisive action. NASA's dedication to providing critical climate data aligns with global efforts to address the profound challenges posed by climate change. As we navigate this unprecedented era of planetary warming, collective action becomes paramount to secure a sustainable future.
