Preliminary calculations* show that surface temperatures<\/a>** averaged over the globe in 2004 were the fourth highest (and the past decade was the warmest) since measurements began in 1861. (Actually, there are measurements at some sites before 1861, but this date is generally chosen as the first time when there is a dense enough network of data available to make a global average meaningful). 2004 was slightly cooler than 2003, 2002 and 1998, with the average world temperature exceeding the 30 year average (1961-1990) by 0.44\u00b0 C. 1998 remains the warmest year, when surface temperatures averaged +0.54\u00b0C above the same 30-year mean. October 2004 was the warmest October on record. Sea-ice extent in the Arctic remains well below the long-term average. In September 2004, it was about 13% less than the 1973-2003 average. Satellite information suggests a general decline in Arctic sea-ice extent of about 8% over the last two and half decades.

Des calculs pr\u00e9liminaires* montrent que les temp\u00e9ratures de surface<\/a>** moyenn\u00e9es sur le globe en 2004 placent cette ann\u00e9e comme la quatri\u00e8me plus chaude (et la derni\u00e8re d\u00e9cennie \u00e9tait la plus chaude) depuis que ces mesures ont commenc\u00e9 en 1861 (en r\u00e9alit\u00e9, il existe des mesures avant 1861 pour quelques stations m\u00e9t\u00e9os, mais il est g\u00e9n\u00e9ralement consid\u00e9r\u00e9 qu’a partir de cette date, il y a un r\u00e9seau de donn\u00e9es disponibles suffisamment dense pour calculer une moyenne globale significative). L’ann\u00e9e 2004 \u00e9tait l\u00e9g\u00e8rement plus froide que 2003, 2002 et 1998, avec une temp\u00e9rature moyenne globale exc\u00e9dant la moyenne des 30 ann\u00e9es de r\u00e9f\u00e9rence (1961-1990) par 0.44\u00b0 C. 1998 reste l’ann\u00e9e la plus chaude, avec des temp\u00e9ratures de surface qui d\u00e9passaient en moyenne de +0.54\u00b0C le m\u00eame intervalle de r\u00e9f\u00e9rence de 30 ans. Octobre 2004 \u00e9tait le mois d’octobre le plus chaud jamais enregistr\u00e9. L’extension de la glace de mer en Arctique est rest\u00e9e bien au-dessous de la moyenne \u00e0 long terme. En septembre 2004, celle-ci \u00e9tait environ 13% de moins que la moyenne sur 1973-2003. Des informations satellitaires sugg\u00e8rent une baisse g\u00e9n\u00e9rale de l’extension de la glace de mer arctique d’environ 8% au cours des 25 derni\u00e8res ann\u00e9es.

_______________
\n*Following established practice, WMO\u2019s global temperature analyses are based on two different datasets. One is the combined dataset maintained by the Hadley Centre of the Met Office, UK, and the Climatic Research Unit, University of East Anglia, UK and the other one is maintained by the USA Department of Commerce\u2019s National Oceanic and Atmospheric Administration (NOAA). Results from these two datasets are comparable: both indicate that 2004 is likely to be the fourth warmest year globally. <\/small>

\n* Suivant la pratique \u00e9tablie, les analyses globales de temp\u00e9rature par WMO sont bas\u00e9es sur deux ensembles de donn\u00e9es diff\u00e9rents. L’un est la combinaison des donn\u00e9es conserv\u00e9es par le Centre Hadley du Met Office (UK) et par l’Unit\u00e9 de Recherches Climatiques de l’Universit\u00e9 d’East Anglia (UK), l’autre est conserv\u00e9 par l’Administration Nationale Oc\u00e9an- Atmosph\u00e8re (NOAA) du D\u00e9partement du Commerce des Etats-Unis. Les r\u00e9sultats de ces deux ensembles de donn\u00e9es sont comparables : tous les deux indiquent que 2004 est susceptible d’\u00eatre la quatri\u00e8me ann\u00e9e la plus chaude globalement.<\/p>\n
