Hello my name is Tori. I think that global warming is a terrible thing, that will cause the fall of Earth as we know it. After I read Step 1 about the greenhouse effect, this is the information I gathered. When the radiation reaches the atmosphere, the radiation goes in and out different ways. Some of the radiation is refelected from Earth. The rest of the radiation is absorbed by Earth. Heat is radiated outward and absorbed by greenhouse grasses. Greenhouse grasses keep Earth warm enough to sustain life. Some human activities, like burning fossil fuels intensify the warming by releasing additon greenhouse gasses into Earth's air. These include carbon dioxie (53%), methane (17%), nitrous oxide (12%), and lastly the "other" gasses (18%). That is what I learned from step 1.

In step 2 we were to create online pictures to show global warming, greenhouse effect, greenhouse gases, and climate change. We had the option to be alone or with a partner my partner was Kaitlyn. On my 1st picture I represented global warming. It shows how the suns rays are heating earth up. My 1st picture also shows how the exhaust from a car or semi-truck goes into the atmosphere. Mr.Heat represents the heat from the Earth getting trapped in the atmospheres gases. My 2nd picture represents the greenhouseeffect. This picture shows the suns rays heating Earth. This causes he carbon to refelct and leave Earth. In my 3rd picture I showed climate change. In this picture iI showed how when the season changes so does the climate. First the tree starts off in the spring/summer stage. Then the tree changes to the autumn or fall stage. Then finally to the winter stage. In my 4th picture I showed the greenhouse gas(es). This picture represents how factories and other fossil fuel burners effect ou atmosphere. It shows how ALCOA's smoke rises up into the air and into Earth's atmosphere. When this happens the smoke or fossil fuels tend to just stay there and don't really move. I hope now you get the jist of what we did in step 2. HI tori. It's Holly, I love you work. Check out my page at Z1-H.H. In step 3 we were told to write 3 causes of global warming. My 1st cause was, carbon dioxide from burning fossil fuels. My 2nd cause was, deforistation especially from tropical trees that are used for wood. Lastly in cause #3, the increase of chemicals and fertilizers on and in cropland.

Is global warming real? In step 4 we were instructed to read one of National Geographics articles on global warming. 1 of the thngs the article talked about was how in the last century Earth's average temperature has increased by 1 whole degree! Sadly, in the artic/polar regions it is increaseing 2x the ammount as Earth as a whole. It may not seem like a lot, but if that happens every century for 600 years, then Earth's average temperature would be 7 degrees higher than it was in 1911! Another shocking thing the National Geographic article talked about was how, the tiny bubles in gas are little pices o history frozen in time. Also some scientists have taken sendiments from mud which has dated back from 1 million years ago. Some of the wood from old trees can tell us a lot to. It can tell us the conditions on Earth 1 hundred to even 1 thousand years ago. So scientists can find out the previous living conditions and temperatures just by looking at something as simple as gas bubbles. The answer yes, global warming is a very real and terrible thing in todays societ
