Siberia, N Canada, Alaska
Warmer temperatire
Expansion of forest inot the North and dieback in the South

Question 2

Answer 2

Caribbean, Indian, Red Sea
Warmer oceans
Increase in coral bleaching

Question 3

Answer 3

Amazon
Warmer and drier
Savannisation

Question 4

What will happen to tundra regions?

Answer 4

N Canada and N Siberia
Warmer temperature
Encroachment of boreal forest & positive feedback loops

Question 5

What will happen to arid grasslands?

Answer 5

Sub saharan africa
Less reliable monsoon season
Hotter and drier

Question 6

What are atmospheric tipping points?

Answer 6

A critical threshold when global or regional climate changes from one state to another. The tipping point may not be reversible

Question 7

What is happening to the Atlantic Meridional overturnign Circulation (Gulf Stream & Labrador current)?

Answer 7

Labrador current slows down due to melting ice which is less dense
Warm current slows down because of more cold water at the surface

Question 8

What is the result of the Gulf Stream slowing down?

Answer 8

UK will get 4C-5C colder
Global disruption to rainfall patterns
Reduction in food supply

Question 9

7 examples of climate change mitigation

Answer 9

1. Less red meat in the diet
2. Afforestation
3. Transition to renewables
4. Recycling
5. Public tranport
6. Drain the paddy fields more frequently
7. Reduce deforestation
8. Carbon capture & storage

Question 10

4 examples of adaptation for climate change

Answer 10

1. Develop vaccines
2. Better storm and flood defences
3. Drought resistant crops
4. Better management of urban heat islands

Question 11

Why are precipitation levels in rainfroests decreasing?

Answer 11

Higher temperatures and deforestation therefore less evapotranspiration

Question 12

What is the tipping point for savannisation in rainforests? (without climate change)

Answer 12

40% reduction in rainforest

Question 13

What is the tipping point for savannisation in rainforests? (with climate change)

Answer 13

20-25% reduction in rainforest

Question 14

What percentage is rainforest reduction currently at?

Answer 14

17% (40 years until complete savannisation)

Question 15

What are the local impacts on loss of rainforest?

Answer 15

Decreasing biodiversity
Local weather = decrease in rainfall = less food production

Question 16

What are the global impacts on loss of rainforest?

Answer 16

Hadley cell = changes to global atmospheric circulation

Question 17

What needs to happen in order to stay under 2*C warming?

Answer 17

Half emissions by 2030
Net zero by 2050

Question 18

What percentage of UK emissions come from heat and electricty?

Answer 18

25%

Question 19

Which renewable energy resource is the cheapest form of electricty in 60 countries?

Answer 19

Solar

Question 20

How much carbon does the average UK person emit each year?

Answer 20

13 tonnes

Question 21

How many trees does the UK aim to plant each year?

Answer 21

20,000 (currently at 10,000 tho)

Question 22

What percentage of carbon sequestration does carbon capture and storage account for?

Answer 22

0.1%

Question 23

What percentage of carbon sequestration will carbon capture and storage account for by 2030?

Answer 23

5-6%

Question 24

What percenatge of UK homes need insulation improvement?

Answer 24

65%

Question 25

What percentage of domestic emissions come from heating?

Answer 25

23%

Question 26

Did you know…

Answer 26

UK has the highest energy bills in Europe
