Kubva kuvandudzwa kweindasitiri shanduko uye kuwanikwa kwemotokari mota, CO2 chisi pamwe nevamwe ivo vakawedzera zvinoshamisa iyo greenhouse mhedzisiro. Gore rega rega mweya unobuda wange uchikwira zvakanyanya uye kusvika padanho rekudarika muganho wakatemerwa nenzanga yesainzi inonzi "isingadzoreke" pamhedzisiro yeshanduko yemamiriro ekunze uye kudziya kwepasi.
Ndeipi mhedzisiro yekuburitswa kweEC2 papasi uye hutano hwevanhu? Vakakwanisa here kudzikisa chisi nemitemo yazvino? Mune ino chinyorwa tichabata nezvimwe zvezvisingazivikanwe izvi kuti iwe uzive panorama yepasirese zvakanaka. Iwe unoda kuziva zvakawanda nezvazvo? Verenga pamusoro kuti uwane.
Yakawedzera greenhouse mhedzisiro
Kune avo vasingazvirangariri zvakanaka, iyo greenhouse mhedzisiro inoitika mudenga uye inoitika kuburikidza nekuita kwemamwe magasi anonzi magreenhouse gases. Pakati pemamwe magasi pane CO2. Kusvika zvino, ndiyo gasi rinoburitsa zvakanyanya pasi rose uye, kunyangwe isina mukana wakakura wekuchengetedza kupisa, kusangana kwayo kwakanyanya zvekuti ndiyo inonyanya kukonzera kudziya kwepasi.
CO2 chisi chinobva kune ese marudzi emoto. Kubva pamoto mune mashanga ari kutsva kusvika kune injini yedhiziri yemota. Maindasitiri, kutakura, kurima, nezvimwe. Iwo ndiwo manyuko makuru eEC2 choutsi mupasi. Nekuda kweizvozvo, tembiricha yepakati yepasi rose iri kuwedzera uye ichikonzera kusaenzana kwakakomba muzvinhu zvipenyu.
Nyora CO2 chisi muna 2017
Kunyangwe paine chokwadi chekuti matekinoroji ari mumunda wesimba rinowedzerwazve ari kukonzera budiriro mumunda we greenhouse gasi inoburitsa, Spain haisi munzira kwayo. Mugore rapfuura 2017, CO2 chisi chakawedzera ne4,46% ichienzaniswa na2016. Kuwedzera uku kunomiririra chinyorwa muhutsi kubva munyika yedu kubvira Kyoto Protocol yatanga kushanda muna 2005.
Izvi zvinokonzerwa nekuti Spain inowedzera kushandiswa kwemafuta pane kusimudzira simba rinowedzerwazve. Mushure mekushandurwa kwemutemo nehurumende yeRajoy, mari dzekubatsirana idzo dzaive nesimba rinowedzerwazve dzakabviswa. Izvi zvakatungamira mukudyara kwekutanga mumhando iyi yeprojekti ichiwedzera zvakanyanya, zvekuti kuzvipira kusimba rinowedzerwazve kwakadzikira.
Kuwedzera kwemweya we greenhouse mumhepo ndicho chikonzero chekuchinja kwemamiriro ekunze. Marasha anoshandiswa pakugadzira magetsi akakura ne21% yegore ra2017. Kune chikamu chayo, gasi rechisikirwo rakawedzerawo mashandisirwo aro mumiti yemubatanidzwa yakasanganiswa ne31,8%. Isu hatisi kutaura nezve mashoma madiki, asi, kuwedzera kwacho kwakakura uye izvi zvinotungamira mukuwedzera kweEC2 emissions mudenga.
Masekete anokonzera choutsi
Nezvikamu, kushandiswa kwesimba rakagadzirwa nefossil fueli kwakakonzera 76,1% yemweya, ichiteverwa nemaindasitiri maitiro (samende, makemikari uye metallurgia maindasitiri) zvakakonzera 9,6% yemagasi, kurima uye zvipfuyo (10,1%) uye marara manejimendi (4,2 %).
Izvi zvinomiririra kuwedzera kwakanyanya kana tichifunga makore maviri ezasi anofungidzirwa neEU. Nekuremekedza emissions muna 1990 yakakura ne18% uye zvine chekuita neya2005 ne22,8%. Chinangwa cheSpain ndechekuderedza gasi rinokanganisa kupisa ne40% na2030 kana ichienzaniswa nemweya waive nawo muna1990.
Kuwedzera kwekubuda kwemhepo kuri kukonzeresa kudzoreredza hupfumi mushure medambudziko uye nekutsamira kwakanyanya pamafuta emafuta. Iko kuwedzera kwese mukuburitsa kunogona kuoneka sechikonzero chekutanga danho redhisabhoni. Inoitwa mushure mekushandurwa kwemhando yekugadzira uye zvishoma nezvishoma, sezvakakurudzirwa neChibvumirano cheParis.
Iwe unofanirwa kufunga kuti kubvisa CO2 kubva kune rimwe gore kuenda kune rinotevera chinhu chisingaite. Kukanganwa zvisaririra zvemoto kuita nzvimbo yesimba rinowedzerwazve chinhu chinotora makore nemakore ekugadzirisa nemaindasitiri, tekinoroji uye vagari.
Ingo chinja kuchinjika
Mafuta emafuta akasimba masimba ane magumo uye ipfupi. Nechikonzero ichi, zvinofungidzirwa kuti chinhu chakanakisa muSpain kuvhara magineti emagetsi anoshanda emagetsi muSpain sezvavanosvitsa makore makumi mana ekuberekwa (magetsi emagetsi enyukireya akagadzirirwa kuve nehupenyu hunoshanda hwemakore makumi mana).
Uye ndezvekuti kana chiitiko chikafungidzirwa umo kugona kwekushanda kwakanyimwa, panosvika gore ra2025 marasha haazopinda grid yemagetsi. 92% yemarasha anopiswa munyika yedu anotengeswa kunze kwenyika.
Kuti udzikise CO2 chisi kubva mukutakura, Hurumende inofanirwa kuita kuzvipira kwakakosha kumotokari yemagetsi. Kufamba chikamu chakakosha kwazvo kurwisa uye icho chinofanirwa kunge chisiri kusvibisa.
Chimwe chiitiko chekutarisa kushanda kwesimba uye kudiwa manejimendi muindasitiri nezvivakwa Nenzira iyi, zvipingaidzo kuzvishandira muSpain zvinofanirwa kudzivirirwa uye simba rakagadziriswazve rinowedzerwa.
CO2 kukuvara kune zvipenyu uye hutano
CO2 emissions ine mhedzisiro yakawanda kune zvese nharaunda nevanhu. Nekuwedzera kwakateedzana kwetembiricha yepasi rose nekuda kwekuchengetedza kupisa ne CO2 iyo polar cap iri kunyungudika uye kukwira kwemwero wegungwa. Uye zvakare, apo CO2 inopinda mugungwa, inoisimbisa, ichideredza zvakanyanya vanhu.
Panyaya yehutano, kusvibiswa kwemhepo kunokonzera zviuru zvekufa nguva isati yakwana pagore kubva pamwoyo uye nezvirwere zvekufema. Iwo mazhinji acho anoitika mumaguta makuru uko kusvibiswa kwemhepo kubva kune yakawandisa traffic traffic kwakanyanya.
Sezvauri kuona, CO2 emissions iri kuramba ichikura kunyangwe Chibvumirano cheParis chiri kutangwa.
