Kubva 2015, chikamu chesimba rezuva nemhepo musimba repasi rose chakawedzera zvakapetwa kaviri, maererano nekufunga tank Ember. Parizvino, inotora chikamu che10% chesimba rose rinogadzirwa, richisvika padanho rezvidyarwa zvemagetsi enyukireya.
Mamwe masosi emagetsi ari kutsiva marasha zvishoma nezvishoma, ayo kugadzirwa kwakadonha nerekodhi 2020% muhafu yekutanga ya8,3 zvichienzaniswa nenguva imwe chete muna 2019. Mhepo uye simba rezuva rakaita makumi matatu muzana ekuderera uku, sekureva kwaEmber, ukuwo kudzikira kwakawanda kwakakonzerwa nedenda re coronavirus kuderedza kudiwa kwemagetsi.
Tsvagiridzo yaEmber inobata nyika makumi mana nesere, inoverengera makumi masere netatu muzana ekugadzirwa kwemagetsi epasi rose. Panyaya yehuwandu hwemagetsi anogadzirwa nemhepo uye zuva, UK neEU zvino vari kutungamirira. Aya mamwe masimba emagetsi parizvino ane 48% yekushandiswa kwesimba muGermany, 83% muUK uye 42% muEU.
Izvi zvakakwirira zvikuru zvichienzaniswa neatatu makuru epasi anosvibisa kabhoni: China, US neIndia. MuChina neIndia, simba remhepo uye rezuva rinopa chikamu chegumi chemagetsi ose. Uyezve, China inotora inopfuura hafu yesimba rose remarasha pasi rose.

Sekureva kweReuters, pakupera kwa2020, chikamu chesimba rinowanikwazve uye simba renyukireya muchimiro cheUS magetsi indasitiri inotarisirwa kudarika chikamu chemarasha.
Izvi zvose zvinokurudzira, asi pachine rwendo rurefu rwekuzadzisa chinangwa chechibvumirano chemamiriro ekunze cheParis 2015 chekudzivirira kuti pasi risadziye zvinodarika 1,5 degrees celsius pamusoro pemvura isati yatanga maindasitiri. Kuzadzisa chinangwa ichi, kushandiswa kwemarasha kunofanirwa kudzikiswa ne13% pagore mumakore gumi anotevera, uye kubuda kwecarbon dioxide kunofanirwa kunge kwabviswa ne10.
"Nyaya yekuti kugadzirwa kwemarasha kwakangodonha 8% panguva yedenda repasi rose inoratidza kuti tichiri kure sei kubva pakuzadzisa chinangwa," akadaro Dave Jones, muongorori mukuru kuEmber. "Tine mhinduro, inoshanda, asi hazvisi kuitika nekukurumidza."
