Climate changes affects of society Glaciers and the atmosphere
Location • The whole world will be confronted with issues with climate at some point.
Risks • Changing temperatures • Unhealthy air to breathe • Change in sea levels • Change in storm seasons • Less fresh water • Less diversity in life
Prevention • Even though there are many different views on the causes of climate change there are many sources proving its occurrence. • Possible sources: • Humans (emissions from cars and burning organics) • Increased volcanism • Over population • Solar Activity
Humans • Many make a correlation to the over population of humans and the increased emissions into the atmosphere.
Volcanism • When a volcano erupts it send gasses into the atmosphere.
Predictions • If the worlds climates continue at the same rate as now: • Massing flooding in coastal cities. • Increase in hurricanes and other storms • Some areas will become colder most on average more extreme weather. • Irreversible damage. • Animals habitats will change. • Crop failures.
Major past events • Evidence suggests other events caused by tilting of the earth had changed. • Plate tectonics may have affected currents. • No ice caps and temperature was 6-8 degrees higher.
