Ikharbon diokside iphula ixesha elitsha lonke

Ukukhutshwa kweCarbon dioxide

Ngexesha le-2016 uxinzelelo lwekhabhon dayoksayidi okanye i-CO2 kwiatmosfera yaphula irekhodi elitsha lembali. Kwakunjalo ukuba Umhlaba wawungayazi imeko efanayo phakathi kweminyaka emi-3 ne-5 yezigidi eyadlulayo. Ngelo xesha, iqondo lobushushu lehlabathi laliphakathi kwe-2 kunye ne-3ºC ephezulu kwaye inqanaba lolwandle lalizi-10 ukuya kwi-20 yeemitha ukuphakama kunanamhlanje.

Yintoni unobangela woku kunyuka kwenqanaba le-CO2? Siza kukuxelela.

Ukusukela kwiNguquko yoShishino (1750), Ubuntu bube neenguqu ezininzi ezivumeleyo ukuba zikhule kwaye ziphile ubomi obutofotofo. Ngokwenza njalo, yaqala ukusebenzisa umhlaba ngamandla, ukugawulwa kwamahlathi kunye nokuxhaphaza i-fuels for energy energy. Zonke, Nangona ekuqaleni sasikholelwa ekubeni ayizukubanesiphumo esibi kwiplanethi, kancinci kancinci siyaqonda ukuba besingalunganga.

Ngokutsho kweFinland Petteri Taalas, uNobhala Jikelele weWorld Meteorological Organisation (WMO), “ukuba asinciphisi ngokukhawuleza ukukhutshwa kwegesi yendalo, ikakhulu i-CO2, Siza kujongana nokunyuka okuyingozi kwamaqondo obushushu kwinkulungwane eseleyo, ngaphezulu ngaphezulu kwethagethi ebekwe kwisivumelwano seParis kwimozulu.

Uxinzelelo lweCarbon dioxide

Kwaye kunjalo, amanqanaba awenzi kodwa ayonyuka. Ukuba ngo-2015 uxinzelelo lwekhabhon diokside ibingama-400,00 iinxalenye ngesigidi (ppm) Ngo-2016 yafikelela kuma-403,3ppm, emele i-145% yento eyayiyiyo kumaxesha angaphambi kokushishina (ngaphambi kwe-1750).

Ukufumanisa ukuba ingxinano ye-CO2 kwiatmosfera yahluka njani, abaphandi bathatha iisampulu ze-ice cores ezindala kwaye bazihlalutye. Ke, baye bakwazi ukufumanisa ukuba, ngaphandle kokuba kuthathwe amanyathelo angqingqwa okuthintela oko, ilizwe esaziyo ukuba lahlukile kakhulu kwisizukulwana esizayo.

Ngolwazi oluthe kratya, unokucofa esi sixhobo.
