What is the abbreviation for 'parts per million' used to measure the concentration of carbon dioxide in the atmosphere?
ppm
CO2
mm
pm
What is the predicted range of global temperature increase by 2100 if humans continue to release carbon dioxide?
0.5oC (0.9oF) to 1.2oC (2.2 oF)
1.2oC (2.2 oF) to 4oC (7.2 oF)
4oC (7.2 oF) to 7oC (12.6 oF)
7oC (12.6 oF) to 10oC (18 oF)
What is the main reason why carbon dioxide is a particularly important greenhouse gas?
It is released at a high rate as we burn fuels
It is the most abundant gas in the atmosphere
It has a short lifespan in the atmosphere
It is easily removed through natural processes
What is the concentration of water vapor in Earth's atmosphere?
78.084%
20.946%
1-4%
0.0412%
What do scientists, activists, and policymakers use predictions of global temperature increase and sea level rise for?
To identify possible solutions
To deny the existence of climate change
To promote the use of fossil fuels
To increase greenhouse gas emissions
Imagine you're a tiny particle in a mixture. You look around and see that you're surrounded by other small particles, all different but well-mixed together. What would you call this type of mixture?
Pure substance
Mixture
Solution
Water vapor
Can you guess the percentage of nitrogen that fills up our Earth's atmosphere? It's more than you think!

Imagine you're a superhero fighting against climate change! Which villainous gas would you be battling against, released in large quantities when we burn fuels like gasoline and coal?
Nitrogen
Oxygen
Carbon dioxide
Methane
Imagine you're a carbon dioxide molecule floating in the atmosphere. How long could you hang out there before other chemical reactions whisk you away?
Just a few minutes - you're a busy molecule!
A few hours - you've got some time to chill!
Hundreds or even thousands of years - you're in for the long haul!
Indefinitely - you're the ultimate free spirit!
Imagine you have a magic wand and you stopped all carbon dioxide emissions tomorrow! How long do you think it would take for CO2 levels to return to pre-industrial times, before we started burning all those fossil fuels?
Just a few years, like a short vacation
A few decades, like watching a tree grow
Hundreds of years, like the age of a giant tortoise
Thousands of years, like the time it took to build the pyramids
