When does global CO2 go down each year?
during June, July, and August
during April, May and June
From June to November
From November to May
Where is Mauna Loa?
Near a city in Hawaii
In a remote location away from cities
Near an industrial complex
What is the significance of Mauna Loa's location? (two reasons)
It is not impacted by a single source of carbon dioxide
It is impacted by global carbon dioxide changes
It can measure the changes based on commuting cars in Honohulu
In can measure the impact of a large factory in Hawaii
What did Keeling's data show?
It showed the variation of carbon dioxide was irregular
It proved the amount of carbon dioxide was increasing in a slow speed
It showed there were seasonal variations of carbon dioxide
What is the cause of seasonal variation of carbon dioxide in Keeling's study?
Human use more coal in winter rather than summer
Plants grow in spring and die back in autumn
Ocean absorb more carbon dioxide in summer
Global average temperature increased rapidly after 1980. What human activity that was considered as the largest relevance to this trend?
The Renaissance
Famicom was released in Japan by Nintendo
Industrial Revolution
The concentration of carbon dioxide dissolved in the ocean is
Increasing
Decreasing
Not changing
Becoming acidic
What scientist is responsible for measuring CO2 in the atmosphere and showing that CO2 is increasing every year?
Albert Einstein
Anthony Davis
Charles Keeling
Steven Jobs
The Keeling Curve "curves" upward. Why?
Because we are in a cooling cycle
Because earth is getting older
Because there is all graphs go upward
Because there is more CO2 in the air each year
How did Charles Keeling get his evidence?
He drilled in the ice of Antartica
He captured air in a glass bubble on top of a volcano
He took samples of soil from volcanoes
He visited other universities around the world
Why do scientists think that the big increase in CO2 in our atmosphere is caused by humans?
Because humans breath out CO2
Because the big increase started at the same time the industrial revolution started - about 250 years ago.
Because that's when volcanoes started putting CO2 into the atmosphere
Because that's when humans started cutting down the rainforest
Why is higher levels of CO2 in the atmosphere bad?
Because higher levels of CO2 also mean less oxygen for humans to breath.
Because higher levels of CO2 mean more plants and forests will die.
Because higher levels of CO2 mean more heat will be trapped in our atmosphere.
Because higher levels of CO2 mean more radiation will be reflected into space and the earth will get cooler
Why are greenhouse gasses bad?
They trap heat from radiation
They reflect heat from the sun
They make it hard for humans to breath
They cause cancer
What does this graph tell us?
This graph tells us that the earth is in a cooling trend
This graph tells us that the CO2 in the atmosphere is falling right now
This graphs shows us that when the CO2 levels go up, the earth's temperature goes up.
This graph shows us the Keeling Curve
What does this graph tell us?
This graph tells us that CO2 has been blue for about 800,000 years
This graph tells us that we have only had CO2 in the atmosphere for 800,000 years
This graph tells us that humans are responsible for climate change
This graph shows that about every 100,000 years we have a cycle of higher and lower CO2 levels in the atmosphere
Which of these gasses in our atmosphere is NOT a greenhouse gas?
Oxygen
carbon dioxide (CO2)
methane
nitrous oxide
According to this graph, what is the most common greenhouse gas?
Flourinated Gases
Nitrous Oxide
Methane
Carbon Dioxide
Which of these statements is TRUE?
All greenhouse gases are bad
Humans are responsible for all greenhouse gases (humans make all greenhouse gases).
If humans stopped putting greenhouse gases into the atmosphere, then our climate would stay the same forever
Trees and plants take CO2 out of the atmosphere
