1. Fill in the definition here:
The total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2).

2. Provide some examples (from the same website):

Amount of CO2 emitted by burning one liter of gasoline: 
This activity add 2.3 kg of CO2 to your  personal footprint.

Driving a car for 6 km: 
This activity add 1 kg of CO2 to your  personal footprint.

Creating 5 plastic bags: 
This activity add 1 kg of CO2 to your  personal footprint.

Producing a cheeseburger: 
This activity add 3 kg of CO2 to your  personal footprint.


3. Quiz results: 

What is your carbon footprint weight? 
My carbon footprint is 94%. 

What is the target weight impact? 
9.9 Tonnes. 

What percentage was in stuff, travel, food, home?
Stuff 31%, Travel 14%, Food 16%, Home 39%. 

4. When was the last time the Earth warmed up so fast? 
To see changes that happen at a speed and size anywhere near what we're experiencing today, we have to go back millions of years to what's called the paleocene-eocene thermal maximum which happened about 55 million years ago.

5. What is the name of the current extinction event? 
We are already in the middle of what scientists have termed the sixth extinction. Another name for this massive die-off is the anthropocene extinction.

6. What will probably happen by 2050? 
Due to climate change and pollution, over half of the world's coral reefs, the nurseries of the sea, have already been lost in the past 30 years. If these trends continue, 90% could be gone by 2050.

7. About what proportion of mammal species could disappear by 2100? 
It's estimated that by the end of the century, between 30% to 50% of all species on Earth could be extinct if we continue on our current pathway.

8. Which type of plant would probably grow faster with more CO2, weeds or crops?
Warmer conditions with higher carbon dioxide levels cause weeds to grow faster, up to three times faster than crops. Not only that, but many weeds and pests are also limited by cold.

9. How many dollars has climate change cost us in wheat and maize losses per year since 1980? 
Since 1980 it's estimated, climate change has already cost us 5 billon dollars a year on average in wheat and maize losses.
