September 2023 was the hottest September – and the largest temperature anomaly – on NASA’s temperature record, GISTEMP.
This visualization shows temperature anomalies along with Earth’s underlying seasonal cycle. Temperatures advance from January through December left to right, rising during warmer months and falling during cooler months. The color of each line reflects the year, with colder purples for the 1960s and warmer oranges and yellows for more recent years.
A long-term warming trend can be seen as the height of each month increases over time, the result of human activities releasing greenhouse gases like carbon dioxide into the atmosphere. The line representing 2023 emerges above all previous years at the end of the animation, with September 2023 particularly distant from previous Septembers. September 2023 was 0.48 degrees Celsius (0.86 degrees Fahrenheit) above the previous hottest September in 2020.
Video Description:
Data visualization of a line graph. On the Y axis is the temperature anomaly in degrees Celsius, ranging from below -2 to above 3. The months of the year are on the X axis, starting with January at left and ending with December at right. Temperatures advance from January through December left to right, and also move up during warmer months and down again during cooler months to form a roughly bell shaped curve. The color of each line reflects the year, with colder purples for the 1960s and warmer oranges and yellows for more recent years. As the animation plays, the years count up from 1960 to 2023. The lines get progressively higher, indicating a long-term warming trend. At the end of the animation, the line representing 2023 emerges above all previous years, with September 2023 particularly distant from previous Septembers.
