Global Temperature
LATEST MEASUREMENT:
LATEST ANNUAL AVERAGE ANOMALY:
2018
An example of a temperature anomaly is how much warmer or colder than the long-term average a unit of time something is (like how much warmer than average the most recent year was globally).
0.8 °C
This graph illustrates the change in global surface temperature relative to 1951-1980 average temperatures. Eighteen of the 19 warmest years all have occurred since 2001, with the exception of 1998. The year 2016 ranks as the warmest on record. (Source: NASA/GISS). This research is broadly consistent with similar constructions prepared by the Climatic Research Unit and the National Oceanic and Atmospheric Administration.
The time series below shows the five-year average variation of global surface temperatures. Dark blue indicates areas cooler than average. Dark red indicates areas warmer than average.
