3. Definition Climate change refers to the change in the average weather conditions. It lasts for an extended period of time.

4. Causes of Climate Change

5. Climate change is caused by Natural Factors Volcanic Eruption Solar Activity Orbital Changes Ocean Current Anthropogenic Factors/ Human Causes Deforestation Coal Mining Burning of Fossil Fuels Industrialization High Population Green House Gases

6. NATURAL CAUSES

7. Volcanic Eruption

8. Volcanic Eruption Volcanoes release the greenhouse gas carbon dioxide, contributing to warming of the atmosphere. But the effect is very small. Emissions from volcanoes since 1750 are thought to be at least 100 times smaller than those from fossil fuel burning.

9. Ocean Currents

10. Ocean Currents Ocean currents act like a conveyor belt, transporting warm water and precipitation from the equator towards the poles and cold water from the poles back to the tropics.

11. Orbital Changes

12. Orbital Changes Earth’s orbit around the sun is due to the gravitational attraction between the earth and the sun. It follows an elliptical path. Currently the earth is closest to the sun in the Northern Hemisphere. However the earth’s tilt of its rotational axis causes bigger changes in incoming sunlight and so it has a bigger effect on the seasons.

13. Solar Variations

14. Solar Variations It has been suggested that changes in the solar output might affect our climate both directly, by changing the rate of solar heating of the Earth and Atmosphere and indirectly by changing the cloud forming process.

15. Human Causes

16. Coal Mining

17. Coal Mining The EIA (Environmental Impact Assessment) estimated that coal mining was responsible for the 10% of the total methane production. Since methane is one of the greenhouse gases it may lead to global warming.

18. Burning of Fossil Fuels

19. how does fossil fuels influence climate? When  fossil fuels are  burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and  climate  change.

20. Use of Plastic Products

21. How do plastics influence climate change? Sunlight and heat cause the  plastics  to release powerful greenhouse gases, leading to an alarming feedback loop. As our  climate  changes, the planet gets hotter, the  plastics   break down into more methane and ethylene , increasing the rate of  climate  change, and so perpetuating the cycle.

22. Industries

23. Deforestation

24. How does deforestation influence climate change? Burning or cutting down trees reverses the effects of carbon sequestration and releases greenhouse gases (including carbon dioxide ) into the atmosphere.

39. Climate Change in india Majuli , the largest riverine island in the Brahmaputra River. Majuli has a very high poverty rate at around 21.47% (according to Jorhat District administration). Climate change has resulted in continuous shifts in rainfall pattern as well as an increase in temperatures of the island. It has also lost visibly large tracts of land due to erosion over the last century. The already low income of island's population is further declining due to lower farm productivity caused by frequent floods, erosion, and siltation. The loss of livelihood due to climate induced events has resulted in forced migration to neighbouring urban centres such as Jorhat .

41. Climate Change in india As climate change becomes more palpable, some parts of India will be more affected. Comparing the average temperature in 2009-18 to the that in 1950-80 reveals that some pockets have already become much hotter. In parts of Rajasthan, Gujarat, Tamil Nadu, Kerala and the North-East, average temperature over the last decade has risen by nearly 1° C compared to the historical average in the 1950-80 period.

42. Climate Change in india A region’s vulnerability to temperature changes depends on several factors such as access to infrastructure (electricity, roads and water connections) and dependence on agriculture. According to the World Bank, central districts in India are the most vulnerable to climate change because they lack the infrastructure and are largely agrarian. Within this region, the districts in Maharasthra’s Vidarbha region are particularly susceptible to climate change damage.

55. Indian Youth Climate Network (IYCN) India has one of the largest youth populations in the world, about two-thirds of its population is under the age of 35. For meaningful long-term change to take place, conversations on climate change must include youth voices. That is why the EDF (Environmental Defense Fund) worked with talented young leaders to set up the  Indian Youth Climate Network (IYCN)  which is India's largest youth network on climate change and has local chapters across the country.
