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
• What is one way methane is released in agriculture?

  Through growing rice in flooded paddy fields
• How does cattle contribute to methane emissions?

  Cattle release methane when they pass wind
• What is one consequence of rising temperatures on polar ice sheets?

  They will melt, leading to increased sea levels
• How can increased sea levels affect low-lying areas?

  They could lead to more flooding
• What severe weather events could climate change lead to?

  More storms in the UK
• How might climate change affect animal distribution?

  It could change the distribution of insects
• What is peer review in the context of climate change research?

  It allows scientists to evaluate each other's evidence
• What is a problem with media stories about climate change?

  They can be simplified or biased
• What uncertainty exists regarding climate change?

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

  In the revision workbook linked in the video
• What is the greenhouse effect?

  It is the warming of Earth's surface due to greenhouse gases
• How does water vapor contribute to climate change?

  It varies with temperature but is a greenhouse gas
• What is the impact of human activities on greenhouse gas levels?

  They increase levels of carbon dioxide and methane
• What are the effects of deforestation on carbon dioxide levels?

  It increases carbon dioxide levels in the atmosphere
• How does agriculture relate to methane emissions?

  Agriculture practices release methane into the atmosphere
• What are the implications of climate change on human health?

  It may change the distribution of diseases
• Why is scientific communication important regarding climate change?

  To clarify complex ideas to the public
• How does speculation affect media coverage of climate change?

  It can lead to misleading information being shared
• What challenges exist in modeling climate change accurately?

  Climate change is complex and difficult to model
