Progress report: Today I finished all 5 of my posterst. The 2 I did at home would not show up as a picture.

11/3 Some factories let of gases that are harmful for the environment. Carbon Dioxide is the gas that the greenhouse gases are mostly made up of. Another gas is Methane and is released up into the atmosphere by coal mining, landfills, and natural gases. Deforestation

11/4 I do think that Global Warming is real because as it said on that first link that the earths temperature has risen. If also says that some ways to find out temperatures from the past are though trees and things buried under lakes and oceans. You can tell warm years apart from cold years on tree rings by how fat the rings are on the tree. I also think that it is real because on the second link (the one with the map) it shows that the sea level has risen. It might have risen because the glaciers are melting and falling into the sea causing the level to rise. Also on the map off of the coast of Brazil or so there has been flooding also and indication that the sea levels could be rising. 3rd link. It says that some penguins breeding pairs decreased a lot!!! This could be a sign of global warming because they might be dead because their homes are melting. Some animals have been moving upward where the climate is not as hot. If this continues theses are some things that might happen. The sea level could rise more than 7 inches.

I think that global warming is real and some thing that my classmate said that was lots and lots of beetles have been eating the woods up in Alaska and that would cause deforestation also. With deforestation would come less plants to breath in Carbon Dioxide and then all of the extra gas would go up into the atmosphere and warm up the earth.
