Causes
What is the most common greenhouse gas?
Carbon dioxide
Is reducing emissions alone enough to stop climate change? Yes or no?
No
What created the Great Pacific Garbage Patch?
Littering and dumping trash in the ocean
What global event “started” climate change? The Industrial Revolution, World War II, The Paris Agreement, and COVID-19
The Industrial Revolution
Which is relatively “better”, CO2 or natural gas?
Natural Gas
List 2 of the top 3 carbon dioxide emitters in California
Transportation, industrial (factories), and electricity
What is the difference between renewable and non-renewable energy?
Renewable energy is more sustainable and can be replenished during the human lifetime
List 2 effects of climate change in the Arctic.
Melting ice caps, dying polar bears, decreased biodiversity, etc
What is the least expensive: nuclear, solar, or coal?
Least to most = Solar, nuclear, coal
What holds more CO2, the atmosphere or the ocean?
The ocean
What do greenhouse gases do?
Trap heat, maintain Earth’s temperature, and too much heats the Earth
What is one way nature can take carbon from the atmosphere?
Photosynthesis, and absorbing carbon into soil
Which traps more heat in the atmosphere: methane or CO2?
Methane
What two years have been the hottest to date?
2023 & 2024 (this year too but its not over yet)
What is a “carbon footprint”
The amount of carbon a person or group emits
What role do humans play in the carbon cycle?
We extract and release more carbon than can be absorbed
What is the best way to slow down climate change?
Stop emissions of greenhouse gases
List 1 effect of coal mining that is not CO2
Toxic coal ash/environments destroyed/ contaminates water

Which of the following was NOT an attempted climate change solution? Artificial volcanoes, putting reflective marbles in the Arctic, creating an artificial ozone layer, feeding garlic to livestock, putting diamonds in space
Creating an artificial ozone layer
What is ocean acidification (in terms of CO2)
More CO2 = higher acidity; the ocean is a carbon sink
What does California get most of its energy from?
Natural Gas
What are fossil fuels, and where do they come from?
Fossil fuels once were carbon-based life forms (plants and animals) that were exposed to heat and pressure for millions of years!
