1. Greenhouse gases from human activities are changing the climate.  Name two significant greenhouse gases.
2. The global average temperature rise since 1850 is 0.8°C.  If emissions dropped to zero now, the predicted further temperature rise is 0.3 to 1.0°C. (making total rise 1.1 to 1.8°C.).  What have scientists from the UK and other countries decided is the maximum global average temperature rise we should permit or we risk a very serious catastrophe?
3. What are 4 of the forecast catastrophic effects if we exceed this maximum global average temperature rise?
4. The present world population is 6.7 billion. What is the forecast world population in 2050?

   • Electricity use
   • Home heating.
7. List 3 ways you could insulate your house to reduce emissions from heating by up to 30% altogether.

   • Gas
   • Electricity
   • Coal

12. Emissions per person associated with a typical British diet, 38% animal-based, 2400kcal/day are 2 tons per year. What do you think are the emissions per person per year for lacto-vegetarians (meat in typical diet replaced with dairy)?

    • The same
    • More
13. And what about emissions per year for a vegan? (0% animal-based).  Try and guess which of these is about right.
    • 1 ton
    • 1.5 tons
