CAUSES OF CLIMATE CHANGE: NATURAL OR MAN-MADE
Climate change is caused by a change in the total amount of energy that is kept within the Earth’s atmosphere. This change in energy is then spread out around the globe mainly by ocean currents as well as wind and weather patterns to affect the climates of different regions or the whole planet. Climate change also describes as a change in the average conditions such as temperature and rainfall in a region over a long period of time.
The Earth’s climate has never been completely static and in the past, the planet’s climate has changed due to natural causes. Natural process are volcanic eruptions, variations in Earth’s orbit or changes in the sun’s intensity. However, humans’ activities can also cause changes to the climate for example by creating greenhouse gas emissions or cutting down forests. Global warming and the climate changes seen today are being caused by the increase of carbon dioxide (CO2) and other greenhouse gas emissions by humans. Human activities like the burning of fossil fuels, industrial production, means of transportation, etc. increase greenhouse gas levels. This traps more heat in our atmosphere, which drives global warming and climate change.
CLIMATE CHANGE THREATS TO LIVELIHOOD
The Indian economy is largely agrarian, with around 65 percent of the population dependent for their livelihoods on agriculture and allied sectors that generate 15 percent Gross Value Added (GVA) (GoI, 2017a). It may be noted that Indian agriculture is the home of small and marginal farmers (80%). Therefore, the future of sustainable agriculture growth and food security in India depends on the performance of small and marginal farmers.
