Satellitobservationer af Jorden har vist, at m\u00e6ngden af metan og kuldioxid i vores atmosf\u00e6re er stigende.<\/p>\n<\/div>\n

Metan og kuldioxid er \u201cdrivhusgasser\u201d, som menes at bidrage til den globale opvarmning. De fungerer som et t\u00e6ppe omkring vores planet, hvor de holder p\u00e5 varmen og f\u00e5r de globale temperaturer til at stige. Dette medf\u00f8rer, at havniveauet stiger, hvilket p\u00e5virker mennesker, planter og dyr.<\/p>\n

Forskere har brugt ESA\u2019s Envisat- og Japans GoSat-satellitter til at overv\u00e5ge niveauerne af disse drivhusgasser. De fandt ud af, at m\u00e6ngden af metan i vores atmosf\u00e6re var forholdsvis konstant indtil 2007, men siden da er den steget med ca. 0,3% hvert \u00e5r. De globale kuldioxidniveauer er steget med omkring 0,5% hvert \u00e5r. Det lyder m\u00e5ske ikke af meget, men det er bekymrende tal, is\u00e6r da lande over hele verden har fors\u00f8gt at reducere udledningen af metan og kuldioxid.<\/p>\n

Forskerne er ikke helt sikre p\u00e5, hvor den ekstra metan stammer fra, men den kommer sandsynligvis fra en r\u00e6kke forskellige kilder, s\u00e5som store rismarker og landbrug med mange f\u00e5r og k\u00f8er. Den ekstra m\u00e6ngde kuldioxid er sandsynligvis en bivirkning af, at mennesker forbr\u00e6nder fossile br\u00e6ndstoffer som kul, olie og gas. Dette producerer energi til at skabe elektricitet og drive vores biler, men frigiver ogs\u00e5 kuldioxid til atmosf\u00e6ren.<\/p>\n

Det er vigtigt at overv\u00e5ge situationen, da det uden n\u00f8jagtige data vil v\u00e6re sv\u00e6rt at reducere m\u00e6ngden af drivhusgasser. For at bidrage til denne opgave vil en kommende ESA-satellit ved navn Sentinel-5P hver eneste dag scanne Jorden for metan, hvilket vil give et mere fuldst\u00e6ndigt billede og bidrage til bek\u00e6mpelsen af de globale klimaforandringer.<\/p>\n
