Global Warming and Climate Change

• What are the two terms discussed in the video?

  Global warming and climate change
• What is the main difference between global warming and climate change?

  Global warming refers to temperature increase; climate change refers to its effects
• What is the atmosphere described as in the video?

  Protective layer of gases around Earth
• How does the atmosphere help regulate Earth's temperature?

  Acts like an insulating blanket or greenhouse
• What temperature extremes does the moon experience due to lack of atmosphere?

  From +100 degrees to -200 degrees
• What happens to the sun's heat energy when it reaches Earth's surface?

  Some is absorbed, most is re-emitted or reflected
• What occurs to the energy absorbed by gas particles in the atmosphere?

  It is re-emitted in random directions
• What is the process called where heat energy stays close to Earth due to gas particles?

  Greenhouse effect
• What gases are included in the group known as greenhouse gases?

  Carbon dioxide, methane, and water vapor
• How has the strength of the greenhouse effect changed over Earth's history?

  It has grown and shrunk repeatedly
• What human activities contribute to the current increase in greenhouse gases?

  Releasing carbon dioxide and methane
• How much has the Earth's temperature increased in the past 100 years?

  Almost one degree
• What does the term climate refer to?

  Long-term weather patterns
• What are some consequences of global warming mentioned in the video?

  More common and severe weather events
• What are the two reasons for sea level rise due to global warming?

  Melting ice and expanding warm water
• What impact does sea level rise have on coastal areas?

  Seasonal flooding and submersion of land
• How does climate change affect wild organisms?

  Changes in temperature and rainfall patterns
• What is likely to happen to biodiversity in the coming decades?

  It is likely to fall dramatically
• What happens to species that cannot adapt to climate change?

  They may not survive or migrate fast enough
• What are the key processes involved in the greenhouse effect?

  • Sun's heat energy reaches Earth
  • Some energy is absorbed, most is re-emitted
  • Gas particles absorb and re-emit energy
  • Heat energy stays close to Earth
• What are the main consequences of global warming and climate change?

  • Increased frequency and severity of weather events
  • Sea level rise due to melting ice and water expansion
  • Impact on wild organisms and biodiversity
• What adaptations might species undergo due to climate change?

  • Migration to cooler regions
  • Adaptation to new environmental conditions
  • Potential decline in species unable to adapt
