Greenhouse Effect

By: Emma Hennessey & Nicole Turner

The Greenhouse Effect is the trapping of the sun's warmth in a planet's lower atmosphere because of the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation coming from the planet's surface. Here is a visual representation to show the greenhouse effect.




Greenhouse Gases in the Atmosphere

Greenhouse gases trap heat onto the earth, creating increased temperatures in many locations. Carbon Dioxide, Methane, Nitrous Oxide, and other gases help trap the heat onto the Earth.


Greenhouse Effect

Positives:

-Natural warming of the lower atmosphere

-Needed to keep plants warm

Negatives:

-Too much of the Greenhouse Effect will heat the planet more, resulting in…

-Global temperatures increasing

-Polar Ice Caps melting

-Sea level to rise

-Coastal cities flooding



What would happen if the amount of Ozone/Oxygen/Carbon Dioxide increased or decreased drastically


Carbon Dioxide:

If the amount of Carbon Dioxide was increased dramatically, everything would get really hot and may become too dangerous to live on. If Carbon Dioxide was decreased, everything on Earth will be freezing and hard to live on.


Ozone:If the amount of Ozone was increased dramatically, it would block too much UV radiation, making it unhealthy and dangerous for us to live on. If the amount of Ozone was decreased, there will be so much UV radiation from the sun, that life would only continue in the oceans where sea water blocks UV rays.


Oxygen:If the amount of Oxygen was increased dramatically, there would be a dangerous chance of things bursting into flame. If it was decreased, then nothing would be able to survive with the atmosphere, because they would have nothing to breathe in.

Global Warming

Global Warming is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. Global warming is mostly caused by having too much Co2 in the atmosphere. My opinion about global warming is that i hope the number of Co2 doesn't get too high so that we can’t live on Earth.


Polar Bears and Global Warming

Polar Bears are one of the several animals strongly affected by Global Warming. Due to the global warming, the polar bear loses its sea ice habitat, making it harder to survive in the climate and area. Global Warming decreases the population of polar bears, moves the sea ice platforms further apart and makes swimming more dangerous for them. It is also more difficult for them to hunt and find food with bad global warming.
