Climate Change: Its impact on Food and Nutrition security, Mitigation strategies for coming decades.
Climate change refers to long-term fluctuations in temperature and weather patterns. Variations in the solar cycle are generally responsible for such fluctuations. But, since the 1800s human activities such as burning of fossil fuels and coal have been the drivers for such changes. When fossil fuels are burned, it causes combustion which increases the heat and light leading to rise in the temperature of the earth, also known as Greenhouse effect.
