The Met Office Hadley Centre monitors a broad range of climate variables and indices. These are used worldwide for climate monitoring and climate modelling and in studies of the causes of climate change.
Our work features prominently in many influential reports such as the Intergovernmental Panel on Climate Change reports and the Stern review and also in prominent scientific papers.
The Met Office Hadley Centre makes the vast majority of its data sets freely available (for academic and personal use only). Commercial use is forbidden under the terms and conditions and commercial organisations should first contact the Met Office Customer Centre.
Further information and data are available from www.metoffice.gov.uk/hadobs.
The red bars show the global annual average near-surface temperature anomalies from 1850 to 2007 for land areas only (top), ocean areas only (middle) and combined land and ocean (bottom). The error bars show the 95% uncertainty range on the annual averages. The thick blue line shows the annual values after smoothing with a 21-point binomial filter. The thin blue lines show the 95% uncertainty on the smoothed curve. Data are from the HadCRUT3 data set. |
Key productsClimate indicators Climate indicators - A selection of charts constructed from the data sets on a quarterly basis. UK specific data sets HadCET - Central England Temperature - the longest continuous temperature record in the world (from 1659). HadUKP - National and regional precipitation series. UKCIP gridded data sets Global data sets HadCRUT3 - Combined land and ocean analysis of surface temperature. HadISST - Sea surface temperature and sea ice analyses. HadSLP2 - Sea level pressure analyses. HadEX - Changes in indices of climate extremes for temperature and precipitation. HadAT - Changes in temperatures in the upper air. Climate change goes on. Average global temperatures are now some 0.75 °C warmer than they were 100 years ago and since the mid-1970s average global temperatures have increased at a rate of more than 0.15 °C per decade. Yet over the last 10 years temperatures have risen more slowly, causing some to claim that global warming has stopped. Here we explain why this is not the case and explains that observed changes are entirely consistent with our understanding of natural fluctuations of the climate within a trend of continuing long-term warming. The evidence is very clear that global temperatures are rising and that humans are largely responsible.
