Q

How can soil carbon storage be improved?

A

Irrigation- controlled amounts of water going to the plants
Not many grazing animals e.g sheep
Adding manures/fertilisers
Revegetation- adding more plants to the grasslands so it takes in more carbon

Q

How can decreasing deforestation help the amount of carbon in the atmosphere?

A

It can be reduced to steady the rates and therefore help with the reduction of atmospheric co2 concerntrations

Q

What have they done with trees in croplands?

A

They grow crops which take in co2 and burn the crop in order to create energy. It’s a carbon neutral solution.

Q

How does reforesting help co2?

A

Adding more trees and forests so it can increase the carbon density above and below the ground.

Q

How can reducing tillage help co2 storage?

A

No ploughing protects the soil and doesn’t aggregate it to break up and release carbon

Q

How does mulching help croplands take in carbon?

A

Mulching is adding bark to the ground or the remainder of plants you do t use e.g roots
This stores carbon in the soil instead of the atmosphere

Q

Who and how much co2 was produced in 2013?

A

Improved aviation practices produces 705million tonnes of co2

17
Q

By 2020 how much more will the global emissions be?

A

70% higher than in 2005

18
Q

In what year did the foundation of the IPCC occur?

19
Q

In 1988 what are the key points from the IPCC?

A

The IPCC set up a monitor and analyse climate change science and advise the UN

20
Q

What does IPCC stand for?

A

Intergovernmental panel on climate change

21
Q

What happened in 1992?

A

The UNFCCC treaty

22
Q

What are the key points in the UNFCCC treaty?

A

A general agreement to stabilise the amount of human induced greenhouse- gas levels in the atmosphere in order to prevent climate change.

23
Q

What happened in 1997?

A

The Kyoto protocol

24
Q

What is the Kyoto protocol?

A

Commits parties by setting internationally binding emissions reduction targets

25
When was the Cancun, Mexico agreement?
2010
26
What are the key points about cancun mexico agreement?
Set if significant decisions made to deal address long-term challenge of climate change
27
When was the Doha conference ? And what was it about?
2012 and the conference included discussions on how to set targets for protocols e.g Kyoto
28
When was the Paris conference and what happened?
2015 and 195 countries agreed to climate change reduction targets enforced by 2020. Aims were to reduce emissions and low global temperature by 1.5'c above pre-industrial levels.
29
What happened in 2016?
The Marrakech conference, they demonstrated that the implementation of the Paris agreement is underway.
30
According to who does 90% of anthropogenic carbon release comes from the combustion of hydrocarbons?
The IPCC
31
By what percentage do scientists estimate the carbon capture can cut emissions by?
90%
32
Name and locate the worlds first commercial carbon capture coal-fire power plant
Saskatchewan
33
How can carbon capture be used to reduce the amount of co2 entering the atmosphere through combustion?
Using technology to capture co2 from industry and put it underground
34
Why do environmentalists have concerns about carbon capture?
They're making it viable because they're making oil and extracting it. One day oil will run out and they won't be able to afford it
35
How can countries use photosynthesis to reduce their carbon emissions?
Planting more trees to act as a carbon sink
36
What does FSC stand for?
Forestry stewardship council
