Detailed explanation-1: -Acetylene doesn’t trap the heat that enters the Atmosphere like other Green House gases such as Methane, Carbon dioxide, Sulphur etc. hence, it doesn’t contribute to Global Warming. Q. Which of the following contribute to global warming?

Detailed explanation-2: -Transportation, Industry, Agriculture, and Land Use and Forestry are four global emission sectors that roughly correspond to the U.S. sectors.

Detailed explanation-3: -Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions. As greenhouse gas emissions blanket the Earth, they trap the sun’s heat.

Detailed explanation-4: -Combustion of fuels, use of aerosol sprays, dust from volcanic eruptions, pollution, smog, etc. result in the greenhouse effect. On the other hand, the use of solar-powered jeepneys does not cause the greenhouse effect because they do not release any harmful gases or particles into the atmosphere.
