What is the gas that scientists focus on that comes from things like burning fossil fuels, driving cars, and breathing?
Carbon dioxide

What is the difference between postive and negative feedback loops? Be specific
Positive increases change = bad
negative decreases change = good
100
What is the difference between climate and weather?
Weather - day to day
Climate - trend over at least 30 years
Triple points if you attempt to moon walk for 5 seconds

What two things does a climograph tell us?
Temperature and precipitation per month.
Triple points if you can beat someone in a race (I choose)

The Atompshere + Why?
Sink = Carbon goes into the atmosphere after most human activities
200
Places on this location on Earth are usually warmer because they get direct sunlight year round.
Equator

Ice reflects sunlight energy, and ocean water absorbs sunlight energy. As the average temperature of the planet increases, more ice melts. This increases the amount of solar energy absorbed by the planet, which increases the average surface temperature further.
Postive - Makes it hotter/more gas
Double points if you can beat a person of my choosing in tic tac toe

What is climate change?
A change in patterns of temperatures and weather patterns over a long period of time.

What month is summer shown in this graph?
June - August
Double points if you can think of a rhyme about climate change

Plants: Why?
sink = absorb carbon to make oxygen
double points if you can show me a picture of one of your animals

Describe what is happening to rates of precipitation and hurricanes because of climate change.
Increased/More Power!

The ocean absorbs CO2 from the atmosphere via diffusion. As concentrations of CO2 in the atmosphere rise, the rate at which CO2 diffuses in to the ocean increases, removing CO2 from the atmosphere at a faster rate. As atmospheric CO2 decreases, global temperatures cool.

How do you tell between summer, winter, spring, and fall on a climograph?
Summer = high temperature
Winter = low temp
Spring = temps rising
Fall = temps decreasing

Animals and humans : Why?
Source: breathing and dying and human activities

What is happening to the amount of energy being reflected vs absorbed on Earth? Why?
More is being absorbed by open water, ice is melting
400
Increasing surface temperatures increase the rate of evaporation. As the rate of evaporation increases, the rate of rainfall increases as well. When it rains, greenhouse gases such as CO2 are removed from the atmosphere, causing it to cool.

Human population is increased - requiring more houses. What can we do?

What trends do you notice in this graph?
No seasons, lots of rain, high temps year round

The ocean: Why?
Sink = the ocean diffuses carbon to feed sea plants and to build shells for creatures

What is the gas that comes from cow farts? This gas is worse than CO2
Methane
500
Increasing surface temperatures cause semi-frozen soil called permafrost to thaw. The warmer it gets, the more it thaws. This permafrost often contains methane molecules locked up within its ice in a form known as Methane Clathrates. As the permafrost thaws, these molecules of methane escape to the atmosphere, where they act as a powerful greenhouse gas, warming the atmosphere and melting more permafrost.

If there is enough activism, the amazon rain forest could quadrouple in size. Why might this be negtaive? (think of tree leaves and bark) What could we do?
More energy absorbed

When is summer on this graph?
No summer !

Rocks and sediment: Why?
Sink : only weathering and erosion can make carbon release from rocks.
