What is the Greenhouse Effect?
100
If you weigh 100 pounds, how much of you is carbon?
What is 18 pounds.
100
Is the climate of the whole Earth really changing?
What is Yes! Earth has been getting warmer—and fast.
100
So what if Earth gets a tiny bit warmer?
What is using lots of NASA satellites and special instruments, scientists see some alarming changes. These changes are happening fast—much faster than these kinds of changes have happened in Earth's long past.

What parts of the world will be under water as sea level rises, inch by inch, foot by foot?
What is Miami, New Orleans, California
100
How is Earth a greenhouse?
What is Earth's atmosphere does the same thing as the greenhouse. Gases in the atmosphere such as carbon dioxide do what the roof of a greenhouse does.
200
Why are they called fossil fuels?
What is Because the fuel in your gas tank comes from the chemical remains of prehistoric plants and animals! All living things on Earth contain carbon.
200
What is climate?
What is "Climate" describes conditions over the long term and over an entire region.
200
What changes have scientists seen?
What is Global air temperatures near Earth's surface rose almost one and one-half degrees Fahrenheit in the last century. Eleven of the last 12 years have been the warmest on record. Earth has warmed twice as fast in the last 50 years as in the 50 years before that.
200
How many feet would be under water if the glaciers melted completely?
What is If it melted completely, sea level would rise by 16 to 23 feet (5 to 7 meters).
200
Is it warm in here, or is it just me?
What is Too much carbon dioxide and other greenhouse gases in the air are making the greenhouse effect stronger.
300
Is carbon in the air good, bad, or just ugly??
What is Here's the big, important thing about CO2: It's a greenhouse gas. That means CO2 in the atmosphere works to trap heat close to Earth. It helps Earth to hold on to some of the energy it gets from the Sun so the energy doesn't all leak back out into space.
300
Compare and contrast weather and climate
What is weather is current conditions at a particular time and place.. Climate is the average weather conditions conditions
300
Why is Earth getting warmer?
What is Here's one clue: As the temperature goes up, the amount of carbon dioxide, or CO2, in the air goes up. And as the carbon dioxide goes up, the temperature goes up even more.
300
How much has the greenhouse gas carbon dioxide increased in the air just in the last few years?
What is roughly 20 parts per million
300
Why can't we just plant more trees?
What is instead of planting more forests, some people are cutting them down and burning them to make more farm land to feed the growing human population.
400
What if there were no greenhouse effect?
What is If it weren't for this greenhouse effect, Earth's oceans would be frozen solid. Earth would not be the beautiful blue and green planet of life that it is.
400
Does what we do matter?
What is Everything that happens here affects something over there.Nothing changes in one place without changing something in another place.
400
How do we know what Earth was like long ago?
What is A big part of the answer is ice cores.Other scientists study cores of sediment from the bottom of the ocean or lakes. Or they study tree rings and layers of rocks to give them clues about climate change throughout history.
400
How much has temperature risen around the world in just a little over 100 years?
What is around 4-5 degrees
400
How is Carbon interacting with the oceans?
What is the increased carbon dioxide in the ocean changes the water, making it more acidic. Ocean creatures don't like acidic water. The bleached out, unhealthy coral in this picture is just one example of what acidic water can do.
500
Explain the relationship between temperatures and carbon in the atmosphere.
What is whenever the amount of CO2 in the atmosphere has gone up, the temperature of Earth has also gone up.
500
What are 3 things humans can do to help the climate?
What is drive electric cars, use more renewable energy, and use less water.
500
Doesn't rising sea level just bring us closer to the beach?
What is Sea level has risen 6.7 inches in the last 100 years. In the last 10 years, it has risen twice as fast as in the previous 90 years. If Greenland's ice sheet were to melt completely, sea level all over the world would rise by 16-23 feet (5 to 7 meters).
500
How much Arctic sea ice has melted just since satellites started observing around 30 years ago?
What is about 1/3
500
How are clouds apart of global warming?
What is As the ocean warms up, more water evaporates into the air. So does more water vapor then mean more warming? And does more warming mean more water vapor? And ‘round and ‘round we go?
