Global Warming Causes&Effects

Natural cause Greenhouse gas

Man-made causes Pollution

Population

Agriculture

Effects on weather Increase in precipitations Heating of the polar region

Extreme weather More areas will be affected by drought Increase in tropical cyclone activity Rise of sea level

Increased freshwater flow Floods Increase in global ocean evaporation

Local climate change Rise of temperature Change in ocean currents or in weather system Change of the hydrological cycle

Glacier retreat and disappearance Rise of sea level Less water availability for human consumption Reductions in glacier extent and thickness

Oceans Increase in ocean acidification Changes in ocean circulation Heating of the ocean surface
