F\u00f6r att kunna f\u00f6ruts\u00e4ga hur mycket koldioxid som tillf\u00f6rs atmosf\u00e4ren \u00e4r det viktigt att ta reda p\u00e5 var den sl\u00e4pps ut och var den tas upp.<\/p>\n<p>Vi m\u00e4nniskor f\u00f6rbr\u00e4nner kol, anv\u00e4nder gas och olja, har m\u00e5nga bilar och f\u00f6rbrukar stora m\u00e4ngder energi f\u00f6r att v\u00e4rma upp v\u00e5ra hem. Allt detta leder till att koldioxid sl\u00e4pps ut i jordens atmosf\u00e4r. I takt med att de globala temperaturerna stiger ser vi f\u00f6r\u00e4ndringar i jordens klimat. Dessa omfattar sm\u00e4ltande glaci\u00e4rer, stigande havsniv\u00e5er och extremv\u00e4der \u2013 allt detta \u00e4r d\u00e5liga nyheter.<\/p>\n<p>En av de mindre k\u00e4nda effekterna av de stigande temperaturerna \u00e4r att sn\u00f6n som t\u00e4cker de vidstr\u00e4ckta skogarna i Kanada, Ryssland, Skandinavien och USA sm\u00e4lter tidigare p\u00e5 \u00e5ret. Detta blottl\u00e4gger m\u00e5nga tr\u00e4d, som tar upp koldioxid fr\u00e5n luften.
