5:37 Effects of Greenhouse Gases on Climate Change
Spec 4.9.2.3
Previous Global Climate Change Next The Carbon Footprint & its Reduction
  • Increase in average global temperature is a major cause of climate change.
  • Earth's surface temperature has increased by around 0.5 degrees in the last 30 years.
  • Increase in greenhouse gases in the atmosphere is believed to cause the greenhouse effect.
  • Greenhouse effect traps heat from the sun, increasing mean global temperature.
  • Small temperature changes can have a huge impact on climate.
  • Global climate change causes sea levels to rise due to melting polar ice caps and glaciers.
  • Rising sea levels increase the risk of flooding and coastal erosion.
  • More frequent and severe storms may occur due to changing temperatures affecting air currents.
  • Patterns of rainfall will change, with more rainfall in some areas and less in others.
  • Changes in rainfall can lead to flooding, droughts, and water shortages.
  • Climate change affects food production, causing crop failures and food shortages.
  • Global climate change affects ecosystems, altering animal and plant behaviors.
  • Plants may flower earlier, risking frost damage and disrupting animal feeding cycles.
  • Birds may lay eggs earlier, risking young dying due to lack of food.
  • Certain animals may come out of hibernation earlier, facing food shortages.
  • Ecosystems can be affected by animals migrating to cooler regions due to climate change.
