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.

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.
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).
Global temperature anomaly data come from NOAA's Global Surface Temperature Analysis (NOAAGlobalTemp), which uses comprehensive data collections of increased global coverage over land (Global Historical Climatology Network-Monthly) and ocean (Extended Reconstructed Sea Surface Temperature) surfaces. These datasets have data from 1850 to the ...
How much have temperatures risen in countries across the world? Our World in Data is free and accessible for everyone. Help us do this work by making a donation. The temperature of the air measured 2 meters above the ground, encompassing land, sea, and in-land water surfaces.
Yearly surface temperature from 1880–2023 compared to the 20th-century average (1901-2000). Blue bars indicate cooler-than-average years; red bars show warmer-than-average years. NOAA Climate.gov graph, based on data from the National Centers for Environmental Information.
The temperature record of the last 2,000 years is reconstructed using data from climate proxy records in conjunction with the modern instrumental temperature record which only covers the last 170 years at a global scale.
