The blue line represents global surface temperature reconstructed over the last 2,000 years using proxy data from tree rings, corals, and ice cores. [1] The red line shows direct surface temperature measurements since 1880. [2] Global surface temperature (GST) is the average temperature of Earth's surface.
According to IPCC Sixth Assessment Report, in the last 170 years, humans have caused the global temperature to increase to the highest level in the last 2,000 years. The current multi-century period is the warmest in the past 100,000 years. [3] The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890.
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.

The graph includes yearly average global temperature both for data from Met Stations and for combined Land-Ocean temperature, with 10 year moving averages overlayed. Licensing This figure was produced by Leland McInnes using gnuplot and Inkscape and is licensed under the GFDL .
English: This bar graph shows changes in global mean temperature between the 1880s and 2000s. Temperature changes are averaged over each decade. From the public-domain source: "While year-to-year changes in temperature often reflect natural climatic variations such as El Niño/La Niña events, changes in average temperature from decade to decade reveal a long-term warming.
While this is the first calendar year on record to top the 1.5 degrees Celsius warming threshold, it's not the first time the planet has passed that mark, including the 12-month global average ...
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.
The global average temperature from June 2023 to May 2024 was 1.63 degrees Celsius above the pre-industrial average, a worrying trend that could signify that the world is moving closer to the ...
