- Global temperature anomalies by month
There are three centres that calculate global-average temperature each month. These work independently and use different methods in the way they collect and process data to calculate the...
Historical and spatial comparisons of local, county, state, regional, national, and global meteorological data to determine trends and patterns
20 gru 2023 · 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.
This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group, derived from raw gridded climatologies from the Climatic Research Unit.

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.
16 lis 2023 · The GISS Surface Temperature Analysis version 4 (GISTEMP v4) is an estimate of global surface temperature change. Graphs and tables are updated around the middle of every month using current data files from NOAA GHCN v4 (meteorological stations) and ERSST v5 (ocean areas), combined as described in our publications Hansen et al. (2010) and ...
