Uusi Communications Earth & Environment<\/em> -lehdess\u00e4 julkaistu kansainv\u00e4linen tutkimus osoittaa, ett\u00e4 Kiinan pienhiukkas- eli aerosolip\u00e4\u00e4st\u00f6jen voimakas v\u00e4heneminen on t\u00e4rkein yksitt\u00e4inen syy ilmaston l\u00e4mpenemisen kiihtymiselle vuoden 2010 j\u00e4lkeen. Aerosolit ovat aiemmin viilent\u00e4neet ilmastoa, mutta nyt niiden v\u00e4heneminen on tehnyt kasvihuonekaasujen l\u00e4mmitt\u00e4v\u00e4n vaikutuksen selvemmin n\u00e4kyv\u00e4ksi. Ilmatieteen laitos osallistui tutkimukseen kattavilla ilmastosimulaatioilla. Tulosten mukaan pelk\u00e4st\u00e4\u00e4n Kiinan aerosolip\u00e4\u00e4st\u00f6jen v\u00e4heneminen on nostanut maapallon keskil\u00e4mp\u00f6tilaa noin 0,07\u202f\u00b0C vuodesta 2010. L\u00e4mmitt\u00e4v\u00e4 vaikutus n\u00e4kyy koko pohjoisella pallonpuoliskolla.<\/p>\n\n\n\n

Vaikka ilmanlaadun parantaminen pelastaa ihmishenki\u00e4, tutkimus korostaa tarvetta nopeisiin kasvihuonekaasup\u00e4\u00e4st\u00f6jen v\u00e4hennyksiin. Tutkimus on osa Ilmatieteen laitoksen pitk\u00e4aikaista kansainv\u00e4list\u00e4 yhteisty\u00f6t\u00e4 aerosolien ilmastovaikutusten tutkimuksessa sek\u00e4 osa ACCC-lippulaivahanketta (Atmosphere and Climate Competence Center).
