FAQs on Fundamentals of Physical Geography: World Climate & Climate Change Video Lecture - NCERT Video Summary: Class 6 to Class 12 (English) - UPSC
|1. What is the impact of climate change on the world?
Ans. Climate change has various impacts on the world, including rising global temperatures, melting glaciers and polar ice, sea-level rise, extreme weather events such as hurricanes and droughts, and the disruption of ecosystems and biodiversity.
|2. How does climate change affect human health?
Ans. Climate change affects human health in several ways. It can lead to an increase in heat-related illnesses, respiratory problems due to poor air quality, the spread of infectious diseases, and malnutrition due to changes in agricultural productivity. Additionally, it can also have negative impacts on mental health and well-being.
|3. What are the main causes of climate change?
Ans. The main causes of climate change are primarily attributed to human activities such as the burning of fossil fuels (coal, oil, and natural gas), deforestation, industrial processes, and agricultural practices. These activities release greenhouse gases into the atmosphere, which trap heat and contribute to global warming.
|4. How does climate change impact biodiversity?
Ans. Climate change poses a significant threat to biodiversity. It can lead to habitat loss, species extinction, altered migration patterns, disruption of ecosystems, and changes in the timing of biological events such as flowering and hibernation. These impacts can have far-reaching consequences for the balance and functioning of ecosystems.
|5. What are the measures to mitigate climate change?
Ans. Mitigating climate change requires a combination of efforts at individual, national, and international levels. Some measures include transitioning to renewable sources of energy, improving energy efficiency, reducing deforestation and promoting afforestation, adopting sustainable agricultural practices, promoting green transportation, and implementing policies to reduce greenhouse gas emissions. International cooperation and agreements, such as the Paris Agreement, are also crucial in tackling climate change effectively.
