This graph shows the change in global surface temperature compared to the long-term average from 1951 to 1980. Earth’s average surface temperature in 2023 was the warmest on record since recordkeeping began in 1880 (source: NASA/GISS).
According to an ongoing temperature analysis led by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by at least 1.1° Celsius (1.9° Fahrenheit) since 1880. The majority of the warming has occurred since 1975, at a rate of roughly 0.15 to 0.20°C per decade.
NOAA Climate.gov graph, based on data from the National Centers for Environmental Information. Global average surface temperature has risen 0.14 degrees Fahrenheit per decade since 1880. The rate of warming has more than doubled since 1981.
16 lis 2023 · The visualization presents the seasonal cycle of temperature variation on the earth's surface. This visualization is updated roughly two weeks after the end of each month. Temperature anomalies are deviations from a long term global average.
20 gru 2023 · Global temperature averages and anomalies are calculated over all land and ocean surfaces. The temperature anomaly is calculated by comparing the average surface temperature of a specific time period (e.g., a particular year or month) to the mean surface temperature of the same period from 1991 to 2020.
18 sty 2024 · The animated bar graph shows global temperatures each year from 1976 (left) to 2023 (right) compared to the 1901-2000 average. 1976 (blue bar at far left) was the last time a year was cooler than the 20th-century average. 2023 (far right) set a new record for warmest year.
