Summary

Expanded record of instrumental temperatures showing recent global warming

This figure shows the last 25 years of globally averaged instrumental surface temperature measurements according to data collected by the Hadley Centre of the UK Meteorological Office and the Climatic Research Unit of the University of East Anglia. Data set TaveGL2v was used. The most recent documentation for this data set is Jones, P.D. and Moberg, A. (2003).

Shown across the bottom are a history of fluctuations in the El Niño–Southern Oscillation and the period of disturbance after the stratosphere-piercing eruption of Mount Pinatubo on June 15, 1991. The volcanic period is defined as the period of satellite-discernible volcanic ash in the upper atmosphere (Luo et al. 2002). The El Niño and La Niña periods are defined here as times when the five-month average of the Nino-3 Index deviated from its mean (over these 25 years) by more than 0.5 °C. Many of the interannual variations in temperature relative to the trend can be explained by the release (during El Niño) or uptake (during La Niña) of thermal energy by the oceans. The eruption of Mount Pinatubo, one of the largest of the century, may have depressed global temperature as a result of expelled ash and sulfates.

This figure was prepared by Robert A. Rohde from publicly available data and is incorporated into the Global Warming Art project.

If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Short Instrumental Temperature Record.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
