SUMMARY:The Measurement of Global Temperature
DESCRIPTION:Global temperature is measured by five different groups across the world (two in USA, one each in the UK, Russia and Japan). Of these, three (the two in the US and the one in the UK) update their databases every month. All five produce essentially the same global temperature average, giving a warming of about 0.8°C since about 1900. Comparisons with many earlier studies (from the 1960s back to the 1880s) are also in excellent agreement.\n\nThe global temperature record is composed of 'weather' station data from land areas and marine data from the far greater area of the oceans. The two 'independent' components of the global temperature record are totally independent, but it should be intuitively realised that the two components should agree on inter-annual and multi-decadal timescales. In this talk Professor Jones will show that they do.
