Ucwaningo olwenziwa yiSpanish National Research Council (CSIC) lukhombisa ukuthi amahlathi aseYurophu alahlekelwe kakhulu amandla awo okumunca ikhabhoni eminyakeni yamuva nje. Ucwaningo lukhomba izici ezimbalwa ezibangela lokhu kwehla futhi ludinga ushintsho olubalulekile ekuphathweni kwamahlathi.
Amahlathi adlala indima ebalulekile ekulweni nokushintsha kwesimo sezulu ngokugcina i-CO2 emkhathini. Bahlanganisa cishe amaphesenti angu-40 wendawo ye-European Union futhi bamunca cishe amaphesenti angu-1990 okukhishwa kwabantu phakathi kuka-2022 no-457. Kodwa-ke, ucwaningo lubonisa ukuthi ukumuncwa kwekhabhoni kwehle kusuka kumathani ayizigidi ezingama-2 e-CO2010 elingana minyaka yonke phakathi kuka-2014 no-332 kuya kumathani ayizigidi ezingama-2020 phakathi kuka-2022 no-2030 cishe nokuncipha kwengxenye yesithathu. Lokhu kubeka engcupheni imigomo yesimo sezulu ye-EU, okuhloswe ngayo ukumunca amathani ayizigidi ezingama-310 e-CO2 elingana no-2050 futhi kuzuzwe ukungathathi hlangothi kwesimo sezulu ngo-XNUMX.
Ukwehla kungenxa yezizathu eziningana. Ukugawulwa kwemithi okuqinisiwe, okuqhutshwa ukwanda kwesidingo sokhuni, kungenye yezimbangela eziyinhloko. Ngaphezu kwalokho, iziphazamiso zemvelo ezivame kakhulu ezifana nemililo, iziphepho, nokuhlasela kwezinambuzane ngokuvamile kuholela ekugawulweni kwemithi ngaphambi kwesikhathi. Ngaphezu kwalokho, ukwanda kwamahlathi kuye kwehle kakhulu, futhi ukutshalwa kabusha kwamahlathi akuvamile. Ukuguga kwamahlathi nakho kunciphisa ukukhula futhi ngaleyo ndlela nekhono labo lokuthatha ikhabhoni. Ukushisa okudlulele kanye nesomiso kunciphisa i-photosynthesis futhi kwenza izihlahla zibe buthaka, okuthi ngokuhamba kwesikhathi kubhebhethekise ukufa kwehlathi kanye nokulahlekelwa kokuthathwa kwekhabhoni.
Ucwaningo luphakamisa amamodeli okuphatha asekelwe kwisayensi ahlanganisa amahlathi obudala obuhlukahlukene namazinga okuvikela ukuze kuthuthukiswe ukuhlukahluka kwemvelo nokugcinwa kwekhabhoni. Ukutshalwa kabusha kwamahlathi kumele kuqondiswe ezindaweni ezinesimo sezulu esivumayo, abacwaningi babhala, njengoba ukuntuleka kwamanzi kusongela ikusasa lezindawo ezintsha zehlathi. Lezi zenzakalo ziqokomisa ukuphuthuma kokushintsha ukuphathwa kwamahlathi aseYurophu ukuze kuvikelwe indima yawo njengezitolo ezigcina ikhabhoni.
