Varje g\u00e5ng vi andas ut sl\u00e4pper vi ut koldioxid i atmosf\u00e4ren. Koldioxid \u00e4r ett exempel p\u00e5 en v\u00e4xthusgas \u2013 en gas som h\u00e5ller kvar v\u00e4rme.<\/p>\n<\/div>\n

Under de senaste 100 \u00e5ren har koldioxidhalten i atmosf\u00e4ren \u00f6kat stadigt. Denna \u00f6kning beror till st\u00f6rsta delen p\u00e5 m\u00e4nsklig verksamhet, s\u00e5som f\u00f6rbr\u00e4nning av olja och kol eller avverkning av skog.<\/p>\n

Skogar tar upp stora m\u00e4ngder koldioxid fr\u00e5n luften. Det lagrade kolet sl\u00e4pps dock ut i atmosf\u00e4ren n\u00e4r tr\u00e4den avverkas eller br\u00e4nns.<\/p>\n

Satellitdata visar att v\u00e4rlden verkar bli varmare. De flesta forskare anser att det finns ett samband mellan den globala uppv\u00e4rmningen och \u00f6kningen av v\u00e4xthusgaser. Detta kallas vanligtvis f\u00f6r \u201cv\u00e4xthuseffekten\u201d.<\/p>\n

Satelliter som ESA:s Envisat hj\u00e4lper oss att l\u00e4ra oss mer om de globala klimatf\u00f6r\u00e4ndringarna och att f\u00f6ruts\u00e4ga vad som kommer att h\u00e4nda i framtiden.<\/p>\n

Vissa instrument ombord p\u00e5 Envisat tar fram dagliga globala kartor \u00f6ver v\u00e4xthusgaser som metan (en gas som ofta anv\u00e4nds i spisar och v\u00e4rmesystem). Andra visar f\u00f6r\u00e4ndringar i temperatur, sn\u00f6, is, sj\u00f6ar och skogst\u00e4ckning.<\/p>\n
