Climate change

• What is happening to the concentration of greenhouse gases in the atmosphere?

  It is increasing
• What is one of the problems caused by methane?

  Methane is causing environmental problems
• What has caused the concentration of methane to rise?

  Increased human activity
• How is methane produced in the environment?

  It is produced in the digestive processes of livestock
• What is the relationship between livestock farming and methane production?

  More livestock farming leads to more methane production
• What is the current presence of methane in the atmosphere?

  It is present in tiny amounts
• What issue arises from the increasing concentration of methane?

  It is an issue as a super effective greenhouse gas
• What scientific consensus exists regarding methane emissions?

  They are caused by human activity
• How does human activity affect the average temperature of the Earth?

  It causes an increase in average temperature
• What is the term for the effect of increased greenhouse gases on climate?

  Global warming
• What type of climate change does global warming represent?

  It is a type of climate change
• What are some consequences of global warming?

  It causes changing rainfall patterns
• What severe weather event can global warming potentially cause?

  Severe flooding
• What is a significant environmental issue related to polar ice caps?

  Melting of polar ice caps
• Why is global warming considered a big problem?

  It could affect the whole world
• What is the accuracy of historical data compared to current records?

  Historical data is much less accurate
• What can current global temperature and carbon dioxide levels be worked out from?

  Measurements taken all over the world
• What is the accuracy of historical data collection methods?

  They were less accurate
• What is a method to estimate past climate data?

  Analyze fossils and tree rings

  Past levels of atmospheric carbon dioxide
• What is the issue with global temperature and carbon dioxide levels?

  There are no records of them.
• What is a problem with certain measurements?

  They are less precise than current measurements.
• What is another issue with these measurements?

  They represent less of global levels.
• What are some ways to reduce carbon dioxide emissions?

  1. Cut down on greenhouse gas emissions
  2. Limit personal use of fossil fuels

  To create financial incentives for reduced CO₂ emissions.
• What is the goal of the UK government's plans?

  To encourage public and industry energy efficiency.
• What should we give the climate?

  Some privacy as it is changing.
• What is not all about climate change?

  It is not all depressing news.
