FAQs on Climate - Chapter 4 Geography NCERT class 11 Video Lecture - Humanities/Arts

1. What is the main cause of climate change?
Ans. The main cause of climate change is the increasing concentration of greenhouse gases in the Earth's atmosphere. These gases, such as carbon dioxide and methane, trap heat from the sun and prevent it from escaping back into space, leading to a rise in global temperatures.
2. How does climate change affect weather patterns?
Ans. Climate change can disrupt weather patterns by altering the distribution and intensity of rainfall, increasing the frequency and severity of extreme weather events such as hurricanes and droughts. It can also lead to shifts in wind patterns and ocean currents, impacting regional climates.
3. What are the impacts of climate change on ecosystems?
Ans. Climate change can have significant impacts on ecosystems. Rising temperatures can disrupt natural habitats, leading to the loss of biodiversity. It can also cause changes in species' migration patterns, affect food availability, and increase the risk of species extinction. Additionally, melting glaciers and rising sea levels can threaten coastal ecosystems.
4. How does climate change affect human health?
Ans. Climate change can have various impacts on human health. Heatwaves and extreme temperatures can increase the risk of heat-related illnesses and deaths. Changes in rainfall patterns can lead to water scarcity and the spread of waterborne diseases. Climate change can also exacerbate air pollution and increase the prevalence of respiratory diseases.
5. What are some strategies to mitigate climate change?
Ans. There are several strategies to mitigate climate change. These include reducing greenhouse gas emissions by transitioning to renewable energy sources, improving energy efficiency, and promoting sustainable transportation. Other measures include conserving forests, adopting sustainable agricultural practices, and enhancing climate resilience through adaptation strategies. International cooperation and policy measures are also crucial for effective climate change mitigation.
