How has our climate changed? Climatic conditions are now monitored right across the world. The widespread use of scientific weather instruments over the last century means we can now reliably measure where, and how large, recent changes in climate have been. There's a wide range of evidence that indicates our climate is warming: Increasing temperatures. We know from global temperature records that the Earth has warmed by about 0.75°C in the last century. There are three centres that calculate global-average temperature each month. • Met [Meteorological] Office, in collaboration with the Climatic Research Unit (CRU) at the University of East Anglia (UK) • Goddard Institute for Space Studies (GISS), which is part of NASA (USA) • National Climatic Data Center (NCDC), which is part of the National Oceanic and Atmospheric Administration (NOAA) (USA) These work independently and use different methods in the way they collect and process data to calculate the global-average temperature. Despite this, the results of each are similar from month to month and year to year, and there is definite agreement on temperature trends from decade to decade (Figure 1). Most importantly, they all agree global-average temperature has increased over the past century and this warming has been particularly rapid since the 1970s.
