Global Warming and Carbon Cycle

What is green house effect?

• Atmosphere trapping little heat and causing the temperature of the Earth to cool down

• Atmosphere trapping too much heat and causing the temperature of the Earth to cool down

• Atmosphere trapping little heat and causing the temperature of the Earth to warm up

• Atmosphere trapping to much heat and causing the temperature of the Earth to warm up
