=The Greenhouse Effect (Step 1)= []

The Greenhouse Effect starts with the sun. When the suns radiation reaches the atmosphere some passes through and is absorbed by Earth. Which causes the surface to warm up.
===When heat is ratiated outward and absorbed by "the Greenhouse Gases" in the atmosphere it becomes a process that prevents heat from vanishing into space plus it keeps the Earth hot enough to help support life.=== ===Somtimes sertant human activities intensify the warming effect by realeasing Greenhouse gases into the atmosphere. Gases include carbon dioxcide (53%), methane (17%), and nitrous oxcide (12%) and the others (18%)===

= = =Global Warming Research (Step 3)= =Some things that cause global warming are carbon dioxcide (CO2), methane released from landfills and agritculture, nitrous oxcide from fertilizers, gases used for refrigeration/other industrial proccers, loss of for forests, but mostly the combustion of fossil fuels in veicles and other industrial products, factoris and electricity usage.= []

=Is Global Warming Real (Step 4)= ===I think Global Warming is real because in the the article I read it talked about how over the last century the Earths tempature has risen about 1 degree Fehrenheit. Though it is hard to tell the exact tempatures of the years past we still can get information, information from trees. Trees help us tell how hot it was hundreds of years ago from their rings. The older a tree is the more rings it has, the warmer and more moist it is the thicker the rings are and that is how we can tell how hot the Earth was hundreds of years ago. Also scientists can figure out the climate from earlier years by checking the bottom of lakes and oceans. That way works when pollen creatures and particles fall to the bottom of lakes and oceans and form sediments. Sediments preserve bits and peices of particles which contain info of the tempature when they fell.===

I'd like to thank Ben Wilson (Z8-B.W.) for giving me some tremendous and helpful ideas.
