A city has reduced its annual CO₂ emissions from 2 million tonnes to 1.5 million tonnes over 5 years. What is the percentage decrease in emissions?
A factory emits 1000 kg of methane (CH₄) and 10000 kg of carbon dioxide (CO₂) per year. If the global warming potential (GWP) of methane is 25 times that of CO₂, what is the total CO₂-equivalent emission from the factory per year?
Describe how ocean acidification is related to the greenhouse effect.
Describe the process by which greenhouse gases trap heat in the atmosphere.
Describe the role of methane in the greenhouse effect compared to carbon dioxide.
Describe two ways in which individuals can reduce their contribution to global warming.
Explain how deforestation contributes to the greenhouse effect.
Explain the difference between the natural greenhouse effect and the enhanced greenhouse effect.
Explain the term 'radiative forcing' in the context of climate change.
Explain why CFCs, despite being present in low concentrations, are considered potent greenhouse gases.
Explain why polar regions are more affected by global warming than the equator.
