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.

The current annual GMST is about 15 °C (59 °F), [6] though monthly temperatures can vary almost 2 °C (4 °F) above or below this figure. [7] The data clearly shows a rising trend in global average surface temperatures (i.e. global warming) and this is due to emissions of greenhouse gases from human activities.
Warming stripes. Not to be confused with Time temperature indicator. An early (2018) warming stripes graphic published by their originator, climatologist Ed Hawkins. [ 1 ] The progression from blue (cooler) to red (warmer) stripes portrays annual increases of global average temperature since 1850 (left side of graphic) until the date of the ...
Including April, the world's average temperature was the highest on record for a 12-month period - 1.61 degrees Celsius above the average in the 1850-1900 pre-industrial period.
The initial version of Global Historical Climatology Network was developed in the summer of 1992. [3] This first version, known as Version 1 was a collaboration between research stations and data sets alike to the World Weather Records program and the World Monthly Surface Station Climatology from the National Center for Atmospheric Research.

English: Video showing most recent ~140 years of global warming in the perspective of the last ~2000 years. Method: I simplified the two source SVG images (below) in Inkscape, exported to big PNG files, and used Photoshop Elements to generate 59 frame-by-frame PNG images for Shotcut to generate the continuous transition this webm video.
Polar and alpine climates has every month of the year with an average temperature below 10 °C (50 °F). [8] [10] ET = Tundra climate; average temperature of warmest month between 0 °C (32 °F) and 10 °C (50 °F). [8] [10] EF = Ice cap climate; eternal winter, with all 12 months of the year with average temperatures below 0 °C (32 °F). [8] [10]
The warmest day on record for the entire planet was 22 July 2024 when the highest global average temperature was recorded at 17.16 °C (62.89 °F). [20] The previous record was 17.09 °C (62.76 °F) set the day before on 21 July 2024. [20] The month of July 2023 was the hottest month on record globally. [21]
