The Greenhouse Effect

The Greenhouse effect is the Process in which sunlight emitted from the sun to our planet through our atmosphere. That sunlight then interacts with the planets greenhouse gasses, gasses in the atmosphere which absorbs and emits thermal radiation. These gasses include Carbon Dioxide (CO2), water vapor, and methane. What happens next is the thermal radiation gets trapped within these greenhouse gasses and the planet overall temperature beings to rise. and we get natural occurrences such as these:   

Pictured is what happens to glaciers as the planets temperature goes up.

10 Signs of Global Warming 
http://cpo.noaa.gov/warmingworld/global_sea_level.html 

1. Air Temperaure Over Land Rises 

2. Rise in air Temperature over Oceans

3. Arctic Sea Ice is Reducing

4. Glaciers Are Melting

5. Global Sea Level Rises

6. Increasing Humidity

7.Temperature of the Oceans Rise

                (damages Coral reefs habitats and marine ecosystems)

8.Rise in the Temperature of Lower Atmosphere

9. Snow is Melting Earlier

                     (changing when and how much water is available for nature and people)

10.Warmer Ocean Surfaces increase the destructive potential of tropical cyclones and hurricanes.
