Step 4 Part 1: I think global warming is real because with Earth's temature getting higher Earth's ice is melting, which means the oceans are rising. Earths tempature has gotten 1 degree warmer over the past century and even warmer in some parts of the arctic. Also persipatation has increased globely. So I think all of thoughs examples are proof of globel warming. Trees can tell what the climate was along time ago because the rings in the tree gets thinker when itswetter and hot the year was. So I think the rings in the trees from along time ago probably are alot thinner than the more recen ring in a trees since earths average tempature is rising.=====

Step 4 Part 2: I still think globel warming is real because the group I was in all agreed Globel warmig is real because Earth's average tempature is going up, how the rings in trees can ttill you what the climate was back then, how globel warming effects animals, the rising of Earth's ocean, and freshwater amounts going down while salt water amounts go up. I think thoughs all are legite reasons that global warming is real. Plus why would scientist make up something fake when all these things that are happening to the world world are caused by mainly the rising of earth's tempature.
