Hi my name is Kaitlin and after reading Step 1 this is what I have learned.


 * __Step 1 The Greenhouse Effect__**

1. The suns radiation reaches our atmosphere some of it is sent back into space but the rest is absorbed by the earth which cause the earth to warm up.

2. The earths heat is pushed outward and sucked up by the greenhouse gases in the atmosphere this keeps the heat from going out into space which keeps earths temputure warm enough to support life.

3. When humans do things like burning fossil fuels that release more greenhouse gases which makes the warming effect increase.

__**Step 2 Poster of Terms**__ For this step we had to make virtual poster define the words global warming, climate change, and greenhouse gases we had a chose we could work alone or with a partner my partner was Tori we created these posters useing paint.



__**Step 3 Global Warming Research**__ In step 3 we had to record 3 causes of global warming so here are my 3 causes which I learned about after reading the National Gepgraphic artical __Causes of Global Warming__

1. The fossil fuels that is released from cars going into the atmosphere. 2. Methane released from landfills and animal waste. 3. Forests that would normally suck up fossil fuels being cut down.

__**Is Global Warming Real Reflection**__ After reading the artical on National Geographic I believe that global warming is very much real and humans are mostly to blame there is too much evidence of it for it not to be real like our polar caps melting, sea levels rising, precipatition ( rain and snowfall) increasing, etc. One thing in the artical that really stood out to me is that globally temputers are already up more then 1 degree and even more in the polar areas. At first I thought no big deal it's only 1 degree plus a little more in the polar caps but then I got to thinking and relized that over time it will be come 2 degrees then 3,4,5 and so one that seemingly little change isn't so little it can melt the polar caps which will cause sea levels to rise causing floods and other unnatural weather patterns.

Yesterday we had a disscusion on the effects of global warming, is it real, and it is a natural cause or are humans to blame. Most children thought that humans were to blame while a few others thought that global warming was just a natural cause.
 * __Is Global Warming Real Group Disscusion__**

__**Additonal Facts**__ If trees are cut down many animals can lose their habitats and will have to move to another ecosystem and then the predators that relied on the animals that lived in the trees for food will no longer have a food source.
