Climate Change Flashcards
What are 2 pieces of evidence that support the start of the Anthropocene
There must be evidence of long term changes to the earth as a global, system ( big changes occurring all over the planet at the same time)
There must be marker of this event that can be identified and dated from digging down into rocks, ocean floor sediment or glacia, ice
What is the greenhouse effect
The greenhouse effect is a process that occurs when gases in earths atmosphere trap the suns heat.
How do you find the percentage increase
Final-initial x100
—————
Initial
What percent does carbon dioxide make up of the emissions
75
Where does carbon emissions come from
Burning fossil fuels to generate electricity
Burning fossil fuels to power transport
Deforsetion
What percent of fluroro gases make up the emissions
2%
What percent does Methane make up of the earths emissions
17
Where does fluror-gases come from
Manmade gases used in aerosol cans and in refrigerators
Where does methane come from
Agriculture (cattle and rice)
Melting permafrost
How much percent of nitrous oxide is made up of greenhouse gas
6%
Where does nitrous oxide come from
Agriculture
Burning fossil fuels
What is the strength of carbon dioxide
1
What is the strength of flurgo gases
Aprox 10,000
What is the strength of methane
30
What is the strength of nitrous oxide
600
What controuises produce the most carbon
China, USA, India
Name three factors that are likely to increase carbon emissions
Large population,
Developed
Lost of fossil feud recourses
List information that demonstrates that earths natural atmosphere is changing
More glaciers are melting into the ocean, and the global sea level is rising, melting in the attic tundra realises large amounts of methane
What is a positive feedback loop and give an example of how it can make climate change worse
A positive feedback accelerates a temperature rise, an example of a positive feedback loop is the melting in the attic tundra releasing large amounts of methane causing more warming to the earth
What is a carbon footprint
A carbon footprint is the amount of carbon related by a individual
How can we reduce our carbon footprimt
Low carbon travel, insulating homes, low energy appliances
What can the government do to help climate change
Producing products and food locally. Providing services to people affected by climate change. Reducing the use of energy in buildings. Local solutions for sustainable energy access and transformation.
