Climate change

• What are the two human activities that increase greenhouse gases?

  Burning fossil fuels and deforestation
• What are the four potential effects of global climate change?

  Rising temperatures, sea level rise, severe weather, and disease distribution changes
• Why are models of climate change not always accepted by everyone?

  Because climate change is complex and difficult to model
• What are the three main greenhouse gases mentioned?

  Water vapour, carbon dioxide, and methane
• How does burning fossil fuels contribute to carbon dioxide levels?

  It releases carbon dioxide into the atmosphere
• What happens to carbon dioxide levels when rainforests are destroyed?

  Carbon dioxide levels increase due to deforestation
• How does agriculture contribute to methane emissions?

  Methane is released from flooded rice fields and cattle
• What is the relationship between greenhouse gas levels and atmospheric temperature?

  Higher greenhouse gas levels lead to increased temperatures
• What is the effect of rising temperatures on polar ice sheets?

  It leads to melting and increased sea levels
• How can climate change affect the distribution of animals?

  It may change the habitats and ranges of species
• What is peer review in the context of climate change research?

  It allows scientists to evaluate and validate evidence
• What issues arise from simplified media stories about climate change?

  They can lead to misunderstandings and bias
• What uncertainty exists regarding climate change predictions?

  We cannot predict temperature increases with certainty
• Where can students find more questions on climate change?

  In the revision workbook linked in the video
• What is the impact of increased sea levels on low-lying areas?

  It could lead to more flooding
• How does climate change potentially affect insect-borne diseases?

  It may change their distribution and prevalence
• How does the process of peer review contribute to scientific understanding of climate change?

  It helps detect false claims and biases
• What is the role of speculation in climate change discussions?

  It can lead to misunderstandings based on incomplete evidence
• Why is it important for scientists to communicate climate change ideas to the public?

  To ensure accurate understanding and awareness
