Worked Solution & Example Answer:The cartoon represents global warming - Junior Cycle Science - Question c - 2019
Step 1
How can human activity give rise to global warming?
Answer
Human activities contribute to global warming primarily through the release of greenhouse gases. These include carbon dioxide (CO₂) from burning fossil fuels, methane (CH₄) from agriculture and deforestation, and nitrous oxide (N₂O) from various industrial processes. The accumulation of these gases in the atmosphere enhances the greenhouse effect, trapping heat and leading to an increase in global temperatures.
Step 2
Give one effect of global warming.
Answer
One significant effect of global warming is sea level rise. As temperatures increase, polar ice sheets and glaciers are melting, contributing to rising sea levels. This can lead to coastal flooding, loss of habitat for plants, animals, and even humans, and increased salinity in estuaries, adversely affecting freshwater resources.
