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.
19 lis 2024 · This chart shows Schmidt’s expectation for how much monthly temperatures from January 2023 to August 2024 would differ from NASA’s 1951-1980 baseline (also known as an anomaly).The expectation (represented as the dashed line in the chart) was based on an equation that calculates global average temperature based on the most recent 20-year rate of warming (about 0.25°C per decade) and NOAA ...
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.
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.
A graph and an animated time series showing the change in global surface temperature relative to 1951-1980 average temperatures. The year 2023 is the warmest on record.
18 sty 2024 · In July, August, and September, global temperatures were more than 1.0°C (1.8°F) above the long-term average—the first time in NOAA's record any month has breached that threshold. Map of global average surface temperature in 2023 compared to the 1991-2020 average.
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.
