Hver gang vi \u00e5nder ud, udleder vi kuldioxid til atmosf\u00e6ren. Kuldioxid er et eksempel p\u00e5 en drivhusgas \u2013 en gas, der holder p\u00e5 varmen.<\/p>\n<\/div>\n

I l\u00f8bet af de sidste 100 \u00e5r er m\u00e6ngden af kuldioxid i atmosf\u00e6ren steget st\u00f8t. St\u00f8rstedelen af denne stigning skyldes menneskelige aktiviteter, s\u00e5som forbr\u00e6nding af olie og kul eller rydning af skove.<\/p>\n

Skove fjerner store m\u00e6ngder kuldioxid fra luften. Dette lagrede kulstof frigives imidlertid til atmosf\u00e6ren, n\u00e5r tr\u00e6erne f\u00e6ldes eller br\u00e6ndes.<\/p>\n

Satellitdata viser, at verden ser ud til at blive varmere. De fleste forskere mener, at der er en sammenh\u00e6ng mellem den globale opvarmning og stigningen i drivhusgasser. Dette kaldes almindeligvis for \u201cdrivhuseffekten\u201d.<\/p>\n

Satellitter som f.eks. ESA\u2019s Envisat hj\u00e6lper os med at f\u00e5 mere viden om de globale klimaforandringer og med at forudsige, hvad der vil ske i fremtiden.<\/p>\n

Nogle instrumenter ombord p\u00e5 Envisat udarbejder daglige globale kort over drivhusgasser s\u00e5som metan (en gas, der ofte anvendes i komfurer og varmesystemer). Andre viser \u00e6ndringer i temperatur, sne, is, s\u00f8er og skovd\u00e6kke.<\/p>\n

S\u00e5danne oplysninger er af afg\u00f8rende betydning for h\u00e5ndh\u00e6velsen af internationale aftaler om at reducere udledningen af drivhusgasser.<\/p>","protected":false},"excerpt":{"rendered":"
