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

1. What are the main causes of climate change?
Ans. The main causes of climate change include the burning of fossil fuels such as coal, oil, and natural gas, which releases greenhouse gases like carbon dioxide and methane into the atmosphere. Deforestation, industrial processes, and agricultural practices also contribute significantly by reducing the Earth's capacity to absorb CO2 and by emitting other greenhouse gases.
2. How does climate change affect weather patterns?
Ans. Climate change leads to more extreme and unpredictable weather patterns. This includes increased frequency and intensity of storms, droughts, heatwaves, and heavy rainfall. As global temperatures rise, the atmosphere can hold more moisture, which can lead to heavier precipitation events, while other regions may experience prolonged dry spells.
3. What are the potential impacts of climate change on ecosystems?
Ans. Climate change can disrupt ecosystems by altering habitats, leading to shifts in species distributions, and affecting food webs. Some species may become endangered or extinct as they struggle to adapt to changing conditions. Additionally, coral reefs and other sensitive ecosystems are particularly vulnerable to temperature increases and ocean acidification.
4. What actions can individuals take to combat climate change?
Ans. Individuals can combat climate change by reducing their carbon footprint through various actions such as using energy-efficient appliances, minimizing car travel, using public transportation, recycling, and supporting renewable energy sources. Additionally, adopting a plant-based diet and reducing waste can contribute to lower greenhouse gas emissions.
5. How do international agreements address climate change?
Ans. International agreements, such as the Paris Agreement, aim to unite countries in the fight against climate change by setting targets for reducing greenhouse gas emissions. These agreements encourage nations to develop strategies for mitigation and adaptation, promote sustainable development, and provide mechanisms for financial and technical support to developing nations.
