The greenshouse effect is when Earth's atmosphere traps radiation because of certain gases which would cause temperature to rise up. The top three gases are H2O which is water, CH4 is methane, and CO2 is carbon dioxide. These three gases are greenhouse gases because H2O causes water vapor to absorb heat radiated from Earth's surface. Methane is a greenshouse effect because it absorbs the sun's heat which warms the Earth's atmosphere. Now, Carbon Dioxide is a gase that enters the atmosphere by burning fossils, solid waste, and wood products. Carbon Dioxide is removed from the atmosphere by being absorbed by plants. These gases are apart of greenhouse effect because they all take apart of the atmosphere which makes up the greenhouse effect. When these gases are hit my infrared light they all act in alike ways such as Carbon Dioxide, when hit it absorbs energy from raidition and the energy from the photons causes CO2 to vibrate, which happens to CH4 and H2O also. The greenhouse effect works when solar energy is absorbed by Earth's surface then goes back to atmosphere as heat. From there on, greenhouse gases absorb the heat sent to the atmosphere.
FeeDback of Melting sea ice becoming warmeR ocean water
Sea ice has a very bright surface which when the sunlight hits the surface it reflects back into space. When the sea ice starts to melt because of warming temperatures, there is fewer bright surfaces to reflect light back into space and more enters is absorbed at the surface which causes higher temperatures. This cycles goes to a slight stop in winter but the cycle begins again in spring. Any small increase in temperature can cause more warmer temperatures which causes the polar region to be the most sensitive to climate change. When the temperature starts to go higher and the sea ice starts to melt which causes the warming. The melting of sea ice can effect the atmosphere because the less light being reflected to space the less energy there'll be and the gases will not be able to abort anything. It can also effect the climate by having species being extinct and having high levels of water which would cause damage to mountains and land. I think this cycle is a negative cycle because of all the consequences it has. "In turn, the oceans release more moisture, which appears to influence atmospheric circulation and cause melting in Arctic permafrost. This, in turn, further increases global warming." (http://www.livescience.com/47508-arctic-sea-ice-melt.html) This example shows that the higher the temperature the more sea ice will melt which will cause global warming. Since the 1970s there has been loss in sea ice of about 1 million and till this day scientists are still trying to figure out why. The loss of sea ice is also 33.3 % per decade of 1981 to 2010.
