Overall, Earth was about 2.45 degrees Fahrenheit (or about 1.36 degrees Celsius) warmer in 2023 than in the late 19th-century (1850-1900) preindustrial average. The 10 most recent years are the warmest on record.

Jan 18, 2024 · Earth’s temperature has risen by an average of 0.11° Fahrenheit (0.06° Celsius) per decade since 1850, or about 2° F in total. The rate of warming since 1982 is more than three times as fast: 0.36° F (0.20° C) per decade. 2023 was the warmest year since global records began in 1850 by a wide margin.

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.

Sep 19, 2024 · The new curve reveals that Earth’s temperature has varied more than previously thought over much of the Phanerozoic Eon, the past 540 million years of geologic time when life has diversified, populated land and endured multiple mass extinctions.

Nov 16, 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.

Jan 10, 2025 · It does not show absolute temperatures; instead, it shows how much warmer or cooler each region of Earth was compared to the average from 1951 to 1980. The bar chart below shows 2024 in context with temperature anomalies since 1880. The values represent surface temperatures averaged over the entire globe for the year.

Jan 15, 2025 · Since 1901, the average surface temperature across the contiguous 48 states has risen at an average rate of 0.17°F per decade (Figure 1). Average temperatures have risen more quickly since the late 1970s (0.32 to 0.51°F per decade since 1979).

Since the 1850's, the average global temperature has increased by 1.9°F. Since the late 1970's, average temperatures have exceeded the last century's average every year. Changes in global temperatures over the past century provide one important line of evidence for the effects of increasing greenhouse gas emissions.

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 ).
