Lesson 7

• Climate change


  A change in the usual atmospheric conditions found in a place such as amount of rain or temperature
• Global warming


  Caused by natural causes like volcanic eruptions, changes in the sun, and Earth's orbital changes
• Global warming


  Caused by man-made causes like burning of fossil fuels, pollution from transportation, industrial processes, and agriculture, and deforestation
• Enhanced greenhouse effect


  Caused by man-made causes of global warming, resulting in global warming
• Global warming and climate change


  Result in drought which reduces crop productivity, changes in ecosystems, melting of ice caps which rises the sea level, unpredictable weather patterns across the globe resulting in frequent and stronger typhoons, and frequent landslides and floods
• Climate change increases our vulnerability to different hazards and disasters
• We cannot deny the fact that the existence of humans has brought this planet into its demise
