What is climate?
Short-term current weather around the world
All of the weather in Earth's past
Long-term average weather over a particular region
What is the main driver of temperature on Earth?
The moon
Wind patterns
The sun
How does solar insolation vary across the Earth?
It is the same everywhere
It hits different parts at different angles
It only affects the equator
Which of these has a high albedo and reflects energy back out into space?
Oceans, rivers, & lakes
Snow & glaciers
Forests & grassland
What role do greenhouse gases play in the atmosphere?
They block sunlight and cool down the Earth
They trap heat and regulate temperature
They have no effect on temperature
What happens when the balance of greenhouse gases is disrupted?
Earth becomes colder
Climate change occurs
Oxygen levels increase
A greenhouse gas is any molecules that absorbs outgoing long-wave radiation from the Earth.
True
False
Earth has never experienced changes in temperature and carbon dioxide levels before.
True
False
Which gas is primarily emitted from landfills and cattle?
Nitrous oxide
Carbon dioxide
Methane
What is the main source of nitrous oxide emissions?
Deforestation
Cow farts
Agricultural fertilizer
How much has the global average temperature increased since the 1800s?
FYI: 1 degree Celsius = 33.8 degrees Fahrenheit
1 degree Celsius
2 degrees Celsius
3 degrees Celsius
Which of the following is a result of climate change affecting habitats?
Organisms must move or die
Increased biodiversity
More stable weather patterns
Why are phytoplankton important?
They are the basis of the marine food web, provide oxygen, and remove carbon dioxide
They bring nutrient-rich water to the surface through upwelling
They are the only organism that can convert nitrous oxide back to oxygen
Who is disproportionately affected by climate change?
Low-income communities and communities of color
Wealthy urban communities
Rural agricultural communities
Which of the following is used to respond to the impacts of climate change?
Sequestration
Adaptation
Mitigation
What is mitigation?
A strategy scientists use to talk about climate change
Solutions to reduce greenhouse gas emissions
Responding to the effects of climate change
What do the layers in an ice core represent?
The age of the glacier
Seasons
Different types of ice
What information can scientists gather from the ice core samples?
Climate history
Geological formations
Ocean current changes
How are carbon dioxide levels measured in the ice?
By tapping into bubbles trapped in the ice
By weighing the ice core
By examining the color of the ice
Why is knowing Earth's climate past important?
To determine ice core drilling locations
To prepare for Earth's climate future
To minimize human impact on climate
