Vital to the existence of life What is a Greenhouse? Glass building used to collect heat to grow plants The Natural Greenhouse Effect The gases in the atmosphere trap heat close to the surface of the Earth Warms the planet This porridge is too cold. Mars Has a much thinner atmosphere. Therefore, little heat is trapped. Frozen planet.

Glass building used to collect heat to grow plants The Natural Greenhouse Effect The gases in the atmosphere trap heat close to the surface of the Earth Warms the planet This porridge is too hot. Venus Has a very thick atmosphere. Therefore, much heat is trapped. Hottest planet in solar system.

Vital to the existence of life What is a Greenhouse? Glass building used to collect heat to grow plants The Natural Greenhouse Effect The gases in the atmosphere trap heat close to the surface of the Earth Warms the planet Problem: Out of balance This porridge is just right. Earth Has a life giving atmosphere that traps just enough heat.

Consequences of a Warming Planet
Melting of glaciers and ice caps Rising sea levels
16
Consequences of a Warming Planet
Melting of glaciers and ice caps Rising sea levels More severe weather and storms Droughts Reduction of crop production

Consequences of a Warming Planet
Melting of glaciers and ice caps Rising sea levels More severe weather and storms Droughts Reduction of crop production Spread of disease Coral Bleaching
18
The Science Since the Industrial Revolution, the rate of CO2 in the atmosphere has greatly increased Correlation between CO2 increase and temperature increase Computer models suggest a continual warming of Earth
19
Take Action Global cooperation needed
Paris Agreement: Nations have pledged to reduce their greenhouse gas emission Reduce fossil fuel usage Better fuel efficiency Carpool Bike/Walk Adjust heat/air conditioner Alternative energy Reforestation Promotion of organic farming

Review Quiz How is the greenhouse effect beneficial?
Name 3 greenhouse gases. Name examples of fossil fuels. Which greenhouse gas is mainly released from the burning of fossil fuels? Fertilizers add which greenhouse gas to the environment? Cattle and farm animals add which greenhouse gas to the environment? Which greenhouse gas is absorbed and removed from the atmosphere as a result of photosynthetic life? Why are organic foods a way to lessen the effects of climate change?
