What Changes Climate Natural causes: Volcanic eruptions Earth’s tilt Continental drift Greenhouse gases

Human causes Increase in green house gases: Carbon dioxide: deforestation, land clearing, agriculture and other activities Methane: domesticated animals (cud-chewing process) Rice and paddy fields (flooded during sowing and maturity periods)

Effects Increase in temperature Rise in sea level Precipitation

Effects on Human health Human health- heat stroke Diseases like malaria and dengue Deaths and injuries due to calamities like: droughts, storms and flooding (water- borne diseases)

Effects on Water Resources Some areas heavy rainfall and some will see low rainfall. Repercussions- drought, rivers drying up, flooding, water-borne diseases Agriculture: decline in crop productivity due to increased temperatures and drought This may lead to food shortage with further social implications.

What can we do? Reduce vehicle use Use fuel efficient vehicles Increase use of solar energy Decrease deforestation and plant forest Reduce your carbon footprint

Individual actions Turn off your appliances when not in use Switch to energy efficient CFL bulbs Buy products made locally and with less packaging Use as little paper as possible (use both sides of paper) Use public transport/ car pool service/ ride a cycle/ walk
