Shirin Carbon na Duniya

The **Global Carbon Project** ( **GCP** ) kungiya ce da ke neman kididdige hayaki mai gurbata yanayi a duniya da musabbabinsa.  An kafa shi a cikin 2001, ayyukansa sun haɗa da kasafin kuɗi na duniya don manyan iskar gas guda uku - carbon dioxide ( CO  ), methane (  ), da kuma nitrous oxide (  ) -da kuma ƙarin ƙoƙarce-ƙoƙarce a cikin birane, yanki, tarawa, da gurɓataccen iska.

Babban manufar kungiyar ita ce fahimtar sake zagayowar carbon. Aikin ya haɗu da masana hayaki, masana kimiyya na ƙasa, da masana tattalin arziki don magance matsalar karuwar iskar gas. A cikin 2020, aikin ya fitar da sabon kasafin kudin Methane na Duniya  da kuma kasafin kudin Nitrous Oxide na Duniya na farko,  iskar gas guda biyu da suka fi rinjaye don dumama bayan carbon dioxide.

The Global Carbon Project yana aiki tare da kungiyoyi da yawa don tattara, nazarin, da kuma buga bayanai game da hayakin gas a cikin hanyar budewa da bayyane, yana samar da bayanan da ke kan shafin yanar gizon da kuma ta hanyar wallafe-wallafen. An kafa shi ne a matsayin haɗin gwiwa tsakanin Shirin Geosphere-Biosphere na Duniya, Shirin Yanayi na Duniya, Shirye-shiryen Dimensions na Dan Adam na Duniya da Diversitas, a ƙarƙashin laima na Haɗin gwiwar Kimiyya na Tsarin Duniya. Ayyuka masu yawa a cikin wannan haɗin gwiwa daga baya sun zama wani ɓangare na Future Earth a cikin 2014.

Shugaban yanzu na Global Carbon Project shine Rob Jackson na Jami'ar Stanford. Shugabannin da suka gabata sun hada da Naki Nakicenovic na Cibiyar Nazarin Tsarin Mulki ta Duniya (IIASA), Corinne Le Quéré na Jami'ar Gabashin Anglia, da Philippe Ciais na Cibiyar Pierre Simon Laplace (LSCE). Babban darakta shi ne Josep Canadell na Kungiyar Binciken Kimiyya da Masana'antu ta Commonwealth (CSIRO) ta Australia.

Ga mafi kwanan nan Global Carbon Budget da aka fitar a watan Disamba na shekara ta 2, GCP ya samar da burbushin CO2 a cikin 2 don tashi da kashi 2.7% (rashin 1.8% zuwa 3.7%) zuwa rikodin tan biliyan 37.1 (Gt) CO2,  kamar yadda manufofi da karfin kasuwa a halin yanzu ba su isa su shawo kan ci gaban amfani da makamashin burbushin burbushin halittu ba. An saita maida hankali ga CO2 na yanayi don ƙaruwa da 2.3 ppm [range 2.0 zuwa 2.6 ppm] don isa 407 ppm a matsakaici a cikin 2018, 45% sama da matakan masana'antu. Karin amfani da iskar gas da mai a duniya shine ainihin abubuwan da ke haifar da karuwar yawan CO2 a yau. Amfani da kwal a duniya zai iya ƙaruwa a cikin 2018 amma har yanzu ya kasance ƙasa da tarihinsa a cikin 2013. A cikin shekaru goma da suka gabata, an kawar da kwal ta hanyar iskar gas, iska, da hasken rana a wasu ƙasashe.

Ga misalai na sadarwa ta baya daga GCP, a ƙarshen 2 masu bincike daga aikin sun tabbatar da cewa hayakin carbon dioxide ya karu sosai zuwa kashi 3.2% a kowace shekara daga 2000. A lokacin, shugaban kungiyar Dokta Mike Raupach ya bayyana cewa "Wannan alama ce mai matukar damuwa.

## Kudin Kasuwancin Duniya
GCP ce ta kafa shi a shekara ta 2005 da Kasafin Kudin Carbon na Duniya littafi ne na shekara-shekara na tushen sake zagayowar carbon da sinks a matakin duniya. A cikin 2013 wallafe-wallafen shekara-shekara na Kasafin Carbon na Duniya ya zama wallafe-wallo na bayanai masu rai a mujallar Bayanan Kimiyya ta Duniya. Kowace shekara ana sake fasalin bayanai tare da duk wani canji a cikin bincike, sakamakon da kuma fassarar zamani game da halayyar sake zagayowar carbon na duniya.

Ma'auni na asali da bayanan da aka yi amfani da su don kammala kasafin kudin carbon na duniya ana samar da su ne ta hanyar kungiyoyi da kungiyoyin bincike da yawa a duniya.

## Atlas na Carbon na Duniya
GCP ce ta kafa shi a cikin 2013 Global Carbon Atlas kayan aiki ne don ganin bayanan da suka shafi sake zagayowar carbon na duniya.

Global Carbon Atlas dandamali ne don bincikawa da kuma ganin bayanan da suka fi dacewa akan kwararar carbon wanda ya haifar da ayyukan ɗan adam da matakai na halitta. Tasirin ɗan adam akan sake zagayowar carbon shine mafi mahimmancin dalilin canjin yanayi.

Wannan aikace-aikacen yanar gizo yana ba da damar yada mafi kyawun bayanai game da sake zagayowar carbon na duniya ga masu sauraro da yawa, daga yara masu makaranta da kuma mutane ga masu tsara manufofi da masana kimiyya. Ya ƙunshi abubuwa uku: 1) Bayyanawa, 2) fitarwa da 3) Bincike. Sashe na fadakarwa an yi niyya ne ga jama'a da waɗanda ke aiki a ilimi. Sashe na fitarwa kayan aiki ne na gani don sassan sake zagayowar carbon na duniya waɗanda ke da alaƙa da fitarwa kuma an yi niyya da farko ga masu tsara manufofi. Sashe na bincike an yi niyya ne da farko ga masu bincike kuma yana aiki ne a matsayin ajiyar bayanai da kayan aikin gani don bayanan kimiyya da aka yi amfani da su don bincika kasafin kuɗin carbon na duniya.

Dukkanin abubuwan da ke cikin Global Carbon Atlas ana sabunta su a kowace shekara, kwanan nan a watan Disamba na 2018, bisa ga bayanan da aka buga a cikin Kudin Carbon na Duniya.
