Greenhouse effect
The warming of the planet through greenhouse gasses.
Greenhouse gasses
Gasses that catch light and heat and trap it in the atmosphere.
Positive feedback loop
When A makes B, which makes more of A.
Negative feedback loop
When A makes B, which lowers the count of A.
What greenhouse gases do
They trap heat and trap the light reflecting off the earth.
Why the greenhouse effect is important
It is important because we add to much co2 when we burn fossil fuels which then adds to the atmosphere, warming the planet.
How humans have affected the greenhouse effect
We burn co2 in factories or at home to fuel our daily lives, which contribute to the high co2 levels.
What ice cores tell us about the patterns of CO2 and temperature for the past 800,000 years
They can fluctuate and we are reaching record highs.
