Q: - Carbon dioxide from the burning fossil fuels enter the atmosphere - The make-up of the atmosphere changes - Some energy from the sun cannot escape back through the changed atmosphere - The earth begins to heat because of the extra trapped energy - Human beings cut down trees - Human beings do not re-plant the trees - Trees cannot help take the extra carbon dioxide from the atmosphere - The extra trapped energy starts to change the earth's short term weather - Eventually the long-term climate patterns start to change - What might be the first step of the process?
A: Human beings burn fossil fuels (oil, gas, etc.)

Q: - The plants and floor absorb the the sunlight - The absorbed sunlight is converted to heat - The heat cannot escape the glass - The heat is trapped in the greenhouse - The hot air rises - The colder air at the top is pushed to the bottom - The colder air is then warmed by the floor and the plants. What might be the first step of the process?
A:
Sunlight passes through the glass into the greenhouse
