Global Warming & Climate Change #91

• What are the two terms often associated with environmental issues discussed in the video?

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

  Global warming refers to temperature increase
• What role does the atmosphere play for life on Earth?

  It acts as an insulating blanket
• What is the temperature range on the moon due to lack of atmosphere?

  100 degrees to -200 degrees
• How does the atmosphere regulate Earth's temperature?

  By absorbing and re-emitting heat energy
• What happens to the sun's heat energy when it reaches Earth?

  Some is absorbed, most is reflected
• What is the process called when heat energy is absorbed and re-emitted by gas particles?

  Greenhouse effect
• Which gases are considered 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 is the current trend in global temperatures over the past century?

  Almost a whole degree warmer
• What does the term climate refer to?

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

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

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

  It causes ice to melt and water to expand
• What impact does climate change have on wild organisms?

  Species may not survive changing conditions
• What are some adaptations species might make due to climate change?

  Adaptation or migration to better regions
• What is likely to happen to biodiversity in the coming decades?

  Biodiversity is likely to fall dramatically
• What is the significance of species moving towards the poles?

  It indicates adaptation to cooler temperatures
• What is the role of greenhouse gases in Earth's temperature regulation?

  They trap heat energy in the atmosphere
