Consequence of global warming:

• Higher levels of carbon dioxide

• Burning fossil fuels

• Rising sea levels

• Using our cars

Causes of global warming:

• Burning coal which releases carbon dioxide

• Burning oil which releases carbon dioxide

• Warmer weather

• Rising sea levels

Consequences of acid rain:

• Lowers pH of rivers

• Lowers pH of soils

• Corrosion of limestone buildings

• Using fossil fuels
