1.3 How Humans Affect The Climate Flashcards
How does livestock enhance the green house effect?
Cattle fartes and rice farming release methane.
How does energy production enhance the greenhouse effect?
Factories use fossil fuels to generate energy which releases CO2.
How does transport enhance the greenhouse effect?
Most land vehicles realease nitrous oxide which is worse than carbon dioxide.
How does energy production enhance the greenhouse effect?
Most industry produces halocarbons and when industrial waste decays it releases methane.
What evidence is there for the human enhancement of climate change?
> Arctic Sea Ice
Gloabal Average Temperature
Sea Level Change
How do we use arctic sea ice as evidence for human enhancement of climate change?
If the amount of arctic sea ice decreases over time we can tell that the global average temperature has gone up, also if the amount of Arctic sea ice has gone down we can say that sea level has risen.
How do we use sea-level change as evidence for human enhancement of climate change?
If the sea level has risen then we can tell that the amount of Arctic sea ice has gone down which tells us that the global average temperature has gone up.
How do we use global average temperature as evidence for human enhancement of climate change?
If the global average temperature has steadily gone up over a long period of time we can tell that climate change is playing a role.
Why are predictions of the future climate uncertain?
Human decisions, if people decide to make sure the climate doesn’t worsen then we will do what it takes to accomplish that.
