<prompt> Hlalosa hore na ke hobaneng ha carbon dioxide e tlatsetsa haholo phetohong ea boemo ba leholimo.nan  <response>: Instruction in English: Explain why carbon dioxide is a major contributor to climate change. . Response in English: Carbon dioxide CO2 is a major contributor to climate change because it is a greenhouse gas, meaning that it traps heat in the Earths atmosphere leading to a warming effect. When energy from the sun reaches Earth, some of it is reflected back towards space, but most of it is absorbed by the Earths surface. This absorbed energy then radiates back into the atmosphere as heat, and greenhouse gases such as CO2 trap this heat instead of allowing it to be released into space. The higher the concentration of CO2 in the atmosphere, the greater the amount of heat it can trap, leading to higher temperatures on Earth. Since the Industrial Revolution, human activities such as the burning of fossil fuels and deforestation have led to an increase in the concentration of CO2 in the atmosphere, from around 280 parts per million ppm to around 415 ppm today. This increase in CO2 concentration is the main reason why the Earths average temperature has risen by around 1 degree Celsius since the 19th century. In summary, carbon dioxide is a major contributor to climate change because it traps heat in the Earths atmosphere leading to a warming effect, and the concentration of CO2 in the atmosphere has been increasing due to human activities. . Response in Sesotho: Carbon dioxide CO2 ke seabo se seholo phetohong ea tlelaemete hobane ke khase e futhumatsang lefatše, ho bolelang hore e tšoara mocheso sepakapakeng sa Lefatše ho isa phellong ea ho futhumala. Ha matla a tsoang letsatsing a fihla Lefatšeng, a mang a eona a khutlela sebakeng, empa boholo ba oona a monngoa ke bokaholimo ba Lefatše. Joale matla ana a monyang a khutlela sepakapakeng e le mocheso, me likhase tse futhumatsang lefatše tse kang CO2 li tšoara mocheso ona ho e-na le ho o lumella hore o lokolloe sebakeng. Ha boemo ba CO2 bo le holimo sepakapakeng, ke moo mocheso oo o ka khonang ho o tšoara, o lebisang ho mocheso o phahameng oa Lefatše. Ho tloha ka Phetohelo ea Liindasteri, mesebetsi ea batho e kang ho chesoa ha mafura le ho senngoa ha meru ho entse hore ho be le keketseho ea CO2 sepakapakeng, ho tloha likarolong tse ka bang 280 ho milione ppm ho ea ho 415 ppm kajeno. Keketseho ena ea CO2 ke lona lebaka le ka sehloohong le entseng hore mocheso oa Lefatše o nyolohe ka hoo e ka bang 1 degree Celsius ho tloha lekholong la bo19 la lilemo. Ka bokhutsoane, carbon dioxide e na le seabo se seholo phetohong ea tlelaemete hobane e tsoara mocheso sepakapakeng sa Lefatse ho isa phellong ea ho futhumala, me khatello ea CO2 sepakapakeng e ntse e eketseha ka lebaka la mesebetsi ea batho.
