100
What has happened to global temperatures over the past century? 
They have increased
100
What was the approximate carbon concentration in 1900 
265 PPM
100
What are the four spheres of earth?
Atmosphere, hydrosphere, biosphere, geosphere
100
If carbon emissions continue rising, what will happen to global temperatures?
They will continue increasing
100
What is one way humans can reduce carbon emissions?
Use renewable energy sources, like wind and solar
200
What was the approximate global temperature in 1900?
58.3°C
200
How much carbon dioxide levels increase from 1960 to 2020?
98 PPM > 316 PPM to 414 PPM
200
What happens to the biosphere when carbon levels rise?
Plant struggle to grow, affecting food availability for humans and animals
200
How do rising temperatures affect extreme weather?
More frequent and intense storms, heat waves, and droughts
200
How does composting help manage carbon level levels?
Adds carbon to soil, improving plant growth, and decreasing CO2 in atmosphere
300
What pattern do temperature in carbon emissions follow?
Both increase overtime in a direct relationship
300
What is the relationship between carbon dioxide and temperature?
As carbon dioxide increases, temperature also increases
300
How does carbon move between the atmosphere and hydrosphere?
CO2 dissolves into ocean water and can return to the air
300
What could happen to polar ice if global temperatures keep rising?
Ice will melt causing sea levels to rise
300
What is regenerative agriculture, and how does it help?
Farming techniques that restore soil health, grabbing more carbon
400
What does historical temperature tell us about climate change?
It shows a steady increase, indicating global warming
400
What is an abnormal trend in carbon emissions based on historical data?
Sharp increase in recent decades, breaking past natural fluctuations
400
Why is carbon in the geosphere important?
Help store, carbon and soil and rocks, preventing too much CO2 in the air
400
How do changes in the carbon cycle affect agriculture?
Poor soil, quality, unpredictable, weather, and food shortages
400
How do trees help combat carbon emissions?
They absorb CO2 from air during photosynthesis
500
How do ice core samples help scientist understand past temperatures?
Contain trapped air bubbles showing past CO2 levels and temperature trends
500
Why do carbon dioxide levels naturally fluctuate throughout the year?
Seasonal plant growth absorbs CO2 in summer, while decay releases it in winter
500
What happens if too much carbon is released into the hydrosphere
Ocean acidification > harming marine life
500
How does climate change impact global water availability?
More evaporation, changing rainfall patterns, and increased droughts
500
What are some government policies that could reduce carbon emissions?
Renewable energy incentives and pollution laws
600
Why are more icebergs expected to form as global temperatures increase?
Increased CO2 increases temperature, leading to glacial, melting, producing more icebergs
600
What is the relationship between population growth, energy use, and carbon dioxide levels?
Population and energy consumption increase, CO2 emissions rise
600
What happens to ocean levels when glaciers and ice sheets melt?
Sea levels rise, causing coastal erosion and flooding
600
What future impacts on climate are predicted if CO2 levels continue to rise?
Rising sea levels, stronger, storms, extreme weather, and biodiversity loss
600
Name three ways, humans can reduce their carbon footprint
Use solar power, drive electric cars, plant more trees
700
Based on the data, when were carbon dioxide levels stable, and when did they start to spike?
Stable from 1850 to 1970, unstable from 1970 to 2010
700
What fossil fuel activities increase carbon dioxide emissions
Burning coal, oil, natural gas, for electric electricity, transportation, and industry
700
How does the loss of wetlands impact the water cycle?
Less humidity, rainfall, and further loss of wetlands
700
How can melting permafrost accelerate climate change?
It releases, methane, a gas stronger than CO2, which causes more warming
700
What is carbon sequestration, and how does it help the climate?
Storing CO2 underground or in plants, keeps it out of atmosphere
800
How does the loss of ice contribute to rising temperatures?
Less ice means less sunlight reflected, causing earth’s surface to absorb more heat
800
How do human activities create feedback loops that worsen climate change?
Rising CO2 melts ice, which absorbs more heat, leading to more warming and ice loss
800
How do dams affect earth’s systems?
Increase ground water recharge, but decrease sediment transport, causing coastal erosion
800
What are some unexpected consequences of rising temperatures?
Changes in ocean currents, disrupted agriculture, new disease patterns
800
Why is reducing deforestation important for climate stability?
Trees absorb CO2, preventing excess greenhouse gases from warming the planet
