This table provides links to the data files containing the climate changes for five variables. Each link is to a data file containing a particular variable for each of the 289 countries and territories.

The first two rows provide information on the observed climate from 1961-90, taken from the TYN CY 1.1 data-set. Both the mean and the interannual standard deviation from 1961-90 are provided. (If you intend to use the standard deviation information, please see the warnings in the TYN CY 1.1 documentation.)

The other 16 rows contain the changes in climate (relative to 1961-90) at the end of the 21st century ('the 2080s', 2071-2100) from 16 scenarios. Each scenario should be treated as equally likely, unless there are specific grounds to treat some as more likely than others. The 16 scenarios represent all possible combinations of four SRES emissions scenarios and four climate models (GCMs).

Please bear in mind that the 1961-90 information is based on observations, and the changes for 2071-2100 are based on models. Therefore it is entirely possible that by combining the two you will produce physically impossible values (e.g. negative precipitation). In such cases, the simplest remedy is to limit the acceptable range of values to the range of the physically possible. So if, for example, you obtain a precipitation total of -10mm in the 2080s, alter this total to 0mm.

The way these files are viewed is browser-dependent. The best way of manipulating the data is to save the file (as a text file) without opening it, and then open the saved text file in a spreadsheet.
