  • How can we stop some sunlight from reaching earth?
    Spray fine mists (aerosols) into space, to reflect sunlight away. (they behave like volcanic gases)
  • Factors that influence climate change, name two
    changes in earth's movement in space, changes in sunspots, volcanic eruption, us
  • What is a greenhouse gas?
    they trap heat around the earth.
  • What are fossil fuels?
    coal, oil, gas
  • What can help people to adapt to changing climates
    Build new homes able to keep out floods, breed new crops that need less water, pay countries to protect rainforest, make the roofs of all buildings white.
  • Define emissions
    waste gases that go into the air, for example from car exhausts.
  • How can we reduce the amount of carbon dioxide thats produced?
    More solar/wind farms, tax air travel/private jets, turn off street lights at 00:00, ban the use of gas for cooking/heating homes, solar panels, electricty 6hr
  • How can we reduce the amount of methane thats produced?
    Double the price of meat, find new farming techniques, more modern up to date facilities.
  • Name at least three impacts of climate change related to weather.
    floods, drought, heatwaves, wildfires, crop yields (less), pests
  • The two main greenhouse gases are...
    carbon dioxide (CO2) and methane (CH4)
  • Complete the sentence; We'd be dead without greenhouse gases, because...
    all the heat would escape from earth and we'd freeze.
  • How can we find ways to remove carbon dioxide from the air? Provide one idea.
    Capture the CO2 from power stations and store it underground. Plant more forests.
  • What country has the highest carbon dioxide emissions per person?
    Qatar
  • Define ice age
    when earths average temperature was low and glaciers spread.
