FAQs on Introduction to Climate Video Lecture - Social Studies (SST) Class 9

1. What is climate change?
Ans. Climate change refers to long-term changes in temperature, precipitation, wind patterns, and other aspects of the Earth's climate system. It is primarily caused by human activities, such as the burning of fossil fuels and deforestation, which release greenhouse gases into the atmosphere and contribute to global warming.
2. How does climate change affect the environment?
Ans. Climate change has several negative impacts on the environment. It can lead to rising sea levels, resulting in loss of coastal habitats and increased flooding. It also disrupts ecosystems, causing changes in species distribution and loss of biodiversity. Additionally, climate change can contribute to more frequent and severe weather events, such as hurricanes, droughts, and heatwaves.
3. What are the main causes of climate change?
Ans. The main causes of climate change are human activities that release greenhouse gases into the atmosphere. These activities include burning fossil fuels for energy, deforestation, industrial processes, and agricultural practices. The greenhouse gases, such as carbon dioxide and methane, trap heat in the Earth's atmosphere and lead to an increase in global temperatures.
4. How do scientists study climate change?
Ans. Scientists study climate change through various methods and techniques. They collect data from weather stations, satellites, and ocean buoys to monitor changes in temperature, precipitation, and other climate variables. They also analyze ice cores and tree rings to understand past climate patterns. Climate models, which simulate the Earth's climate system, are used to project future climate scenarios based on different greenhouse gas emission scenarios.
5. What can individuals do to combat climate change?
Ans. Individuals can contribute to combating climate change by making sustainable choices in their daily lives. This includes reducing energy consumption by using energy-efficient appliances, practicing eco-friendly transportation methods such as cycling or using public transport, and minimizing waste generation. Supporting renewable energy sources, planting trees, and advocating for climate-friendly policies are also effective ways to make a positive impact on the environment.
