Managing Climate Change Flashcards
How can climate change be managed? (4)
- Alternative energy production
- Carbon capture
- Planting trees
- International agreements
The burning of fossil fuels contribute to how much percent of human produced CO2 emissions?
87%
Name alternative energy sources. (3)
- Hydro-electricity
- Nuclear power
- Solar, wind and tides
Which fossil fuel is the most polluting?
Coal
What is carbon capture and storage (CCS)
Technology which captures up to 90% of CO2 coming from the use of fossil fuels.
What are the disadvantages of Carbon capture and storage?(2)
- Difficult to store carbon
- Expensive technology
How and where is carbon stored once captured?
- carbon gas is compressed into a liquid and transported by a pipeline
- injected into the ground to be stored in suitable geological resevoirs (eg depleted oil and gas fields)
Why is planting trees good?
- Trees act as carbon sinks
- Release moisture into the air
- moisture forms clouds reducing incoming solar radiation
Advanatges of plantation forests
- Absorbs CO2 at a faster rate than natural forests.
- Lasts up to 50 years
Why are international agreements important to solve climate change? (3)
- Educates countries about the problem and consequences of climate change.
- Communities can share solutions and help other countries achieve them
- legally bind countries to reduce their emissions
When did the Kyoto Protocol agreement happen?
2005
When did the Copenhagen accord take place?
2009
When did the Paris Agreement happen?
2015
What was agreed in the Kyoto protocol?
-Over 170 countries agreed to reduce carbon emissions by 5.2%
What happened in the Copenhagen Accord?
- Planned to reduce emissions of developing countries with financial support
- However not legally binding
