Ilmastonmuutoksella tarkoitetaan sit\u00e4, ett\u00e4 normaaleissa ilmasto-olosuhteissa tapahtuu suuria muutoksia pitk\u00e4n ajanjakson aikana. Maapallon ilmasto n\u00e4ytt\u00e4\u00e4 muuttuvan eritt\u00e4in nopeasti, mit\u00e4 ei ole tapahtunut viimeisen j\u00e4\u00e4kauden p\u00e4\u00e4ttymisen j\u00e4lkeen, 10 000 vuotta sitten. Tutkijat eiv\u00e4t ole varmoja siit\u00e4, kuinka paljon ilmasto on tarkalleen ottaen muuttunut tai miksi n\u00e4in tapahtuu, mutta he uskovat, ett\u00e4 ainakin osa muutoksista johtuu ihmisen toiminnasta.<\/p>\n<\/div>\n

Tutkijat uskovat, ett\u00e4 maailma on l\u00e4mpenem\u00e4ss\u00e4, mik\u00e4 n\u00e4kyy napaj\u00e4\u00e4tik\u00f6iden sulamisena ja merenpinnan nousuna. He katsovat, ett\u00e4 syyn\u00e4 on osittain \u2018kasvihuonekaasujen\u2019 lis\u00e4\u00e4ntyminen \u2013 tehtaista, autoista ja lentokoneista ilmakeh\u00e4\u00e4n p\u00e4\u00e4sevien kaasujen m\u00e4\u00e4r\u00e4 on kasvanut. Maa-ilmasto l\u00e4mpenemist\u00e4 pahentavat my\u00f6s metsien hakkuut sek\u00e4 \u00f6ljyn ja kivihiilen polttaminen. Otsonikerros, joka suojaa meit\u00e4 auringon haitallisilta UV-s\u00e4teilt\u00e4, on ohentunut huomattavasti viime vuosina ja joissakin paikoissa se on tuhoutunut kokonaan. T\u00e4m\u00e4 on tapahtunut k\u00e4ytt\u00e4miemme aerosolien m\u00e4\u00e4r\u00e4n seurauksena.<\/p>\n

Kaikkia n\u00e4it\u00e4 aiheita tutkitaan nyt avaruudesta k\u00e4sin satelliittien avulla. T\u00e4m\u00e4n ansiosta voimme oppia lis\u00e4\u00e4 maapallon ilmastosta ja seurata mahdollisia muutoksia.<\/p>","protected":false},"excerpt":{"rendered":"
