The Green House affect- 1.It starts with the sun: Surface water is warmed up by sun's radiation reaching our atmospere, some is reflected back into space and some passes through our atmosphere and is absorbed by the Earth. 2.Greenhouse Effect: Heat from the Earth is radiated outward, it is absorbed by "greenhouse gases" in the atmosphere. This process keeps heat from disapearing into space and keeps Earth warm enough to support life. 3.Greenhouse gases: Some human activities (such as burning fossil fuels) intensify the burning effect by releasing greenhouse gases into the atmosphere. These gases are methane, carbon dioxide, and nitrous oxide, they have heat trapping cappacities.

Vocabulary- Carbon dioxide: A colorless, odorless gas. (A.K.A CO2.) This gas is produced by burning carbon and organic compounds. Also produced by the process of respiration and is absorbed by plants during photosynthesis. Methane: A colorless, odorless gas. (A.K.A. CH4.) Methane is the main constituent of natural gas. It is the simplest member of the alkane series. Deforestation: The state of being clear of trees.

3 Reasons Global Warming Reflection- The gas most responsible for global warming is carbon dioxide, but all the different greenhouse gases have very different heat-trapping abilities. Carbon dioxide adds the most heat to the atmosphere compared to the other greenhouse gases due to its high volume concentration. For 3.5 million years the Earth's climate has fluctuated. Temperature has risen 1.2-1.4 degrees farenheit through the last century. Scientist believe the change in temperature is due to human activity (such as burning fossil fuels). This process is called Global Warming. Since industrial revolution began, factories, powerplants, and cars have been burning fossil fuels. These fossil fuels are oil and coal. Oil and coal have been releasing huge ammounts of carbon dioxide and other gases into the atmosphere. These gases released are called Greenhouse Gases.Greenhouse gases trap heat near the Earth through a process called the Greenhouse Effect. Evidence for global warming has been by having very warm years. 1998 so far has been the warmest year in history. 2005 ended up coming in second place, for warmest year due to global warming. Arctic sea ice is also shrinking, it has declined by 10 percent already. Developing new communities, and countries has been increasing global warming also. Scientists predict increases in global warming for the future.

"Is Global Warming Real Reflection"- All over the world, the Earth is showing signs that it is warming up. Other than using thermometers, scientists are using the environment, to see fluctuations in the environment. Trees are able to tell us about the evironment hundreds, to thousands of years ago. They are able to do this by showing us their rings on the inside of them. How has the energy from the sun changed from the past, to the present? Global Warming Climate Impacts: Fresh Water Resources- -Decreased snowpack -Water shortages -Changes in precipitation -Drought -Receding glaciers Ecosystems- -Species extinction -Species losses -Reductions in sea ice -Loss of biodiversity Food and Forests- -Increasing yields -Reduced growing seasons -Changing yields -Changing forests Costal Areas- -Rising sea levels -Severe storms -Flooding -Populations at risk Industry and Society- -Reduced tourism -Unsustainable development Health- -Heat waves -Changing range of disease -Increased disease Effects of Global Warming- -Sea level rise became faster over the last century. -Precipitation has increased across the globe. -Ice is melting worldwide, especially at Earth's poles.

What We Should Do To Reduce Global Warming: We should use more solar energy. Solar energy would help reduce global warming if we use it for powerplants, factories, and cars. Instead of burning fossil fuels and releasing greenhouse gases into the air, we could being reducing global warming. If we start off small with maybe one powerplant, factory, and a little bit more solar powered cars, it could probably still make a big difference. If this works out, more factories, powerplants, and cars would be using solar power energy. This would be a great way to put a stop to global warming.
