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
Why would a scientist choose Hawaii to study the atmosphere?
It is easy to get scientists to live in Hawaii
Since it is near the equator, it has warm days and nights
The air is fresh since it is not near any large cities and pollution
Great surfing
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
How did scientists gather information about the atmosphere in the time of the dinosaurs?
They drilled in ice in Antarctica and studied the gas in the trapped bubbles
They used glass bubbles to gather air samples
They visited schools all over the world
They studied fossils
How long has the earth been going through cycles of high-levels of CO2 and low-levels of CO2?
Ever since Charles Keeling has been measuring the atmosphere
Ever since the Industrial Revolution - about 250 years ago.
Ever since the last ice age - about 10,000 years ago
Ever since the earth has had an atmosphere - over 4 billion years ago
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 do scientists think that the Industrial Revolution was bad for our atmosphere?
Because when machines were invented, they created a lot of smoke and heat
Because when machines were invented, they used fossil fuels
Because when machines were invented, we stopped using natural energy from horses and cows
Because when machines were invented, they used the energy from fossil fuels and made greenhouse gasses that trapped heat
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
