Global warming & Climate change

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

  Global warming refers to temperature rise; climate change refers to weather pattern effects
• What is the atmosphere described as in the video?

  It acts like an insulating blanket or greenhouse
• Why is the atmosphere essential for life?

  It regulates temperature and protects life
• How does the temperature on the moon compare to Earth?

  The moon varies from +100 to -200 degrees
• What happens to the sun's heat energy when it reaches Earth?

  Some is absorbed, most is re-emitted or reflected
• What do gas particles in the atmosphere do with absorbed energy?

  They re-emit it in random directions
• What is the greenhouse effect?

  It's the process of gases trapping heat energy
• How has the strength of the greenhouse effect changed over time?

  It has grown and shrunk repeatedly
• What human activities contribute to global warming?

  Releasing carbon dioxide and methane
• How much has the Earth warmed in the past 100 years?

  Almost one degree Celsius
• What does climate describe?

  Long-term weather patterns
• What are some consequences of global warming?

  More common and severe weather events
• What causes sea level rise due to global warming?

  Melting ice and expanding ocean water
• How does melting ice contribute to sea level rise?

  It flows into the ocean, increasing volume
• What is a general impact of climate change on wildlife?

  Species may not survive changing conditions
• How are some species responding to climate change?

  They are migrating towards cooler poles
• What is likely to happen to biodiversity in the coming decades?

  Biodiversity is likely to fall dramatically
• What are the main processes involved in the greenhouse effect?

  • Sun's heat energy reaches Earth
  • Some energy is absorbed by the ground
  • Most energy is re-emitted or reflected
  • Gas particles absorb and re-emit energy
  • Heat energy stays close to Earth longer
• What are the consequences of global warming on weather patterns and sea levels?

  • Increased frequency and severity of weather events
  • Sea level rise due to melting ice and thermal expansion
  • Seasonal flooding and submersion of coastal areas
• How does climate change affect wildlife and biodiversity?

  • Species may not survive changing conditions
  • Some species adapt or migrate to better environments
  • Biodiversity is likely to fall dramatically
