FORCES THAT AFFECT CLIMATE AND HOW CLIMATE IS RECORDED
When the ice and air bubbles and the dust are trapped it changes the temperature, humidity, atmospheric circulation, volcanice activity, extent of sea ice and pollution by human activity. When u look at the tree rings, you can see the different types of layers. Each rings tells us the growth of the tree during certain time. The Thick rings indicates the rapid growth during warm and wet years. The Thin rings tells us that it was slow growth which means it was a cold weather and dry years.

Tree-Ring Section. When you look at this tree, you can right away notice that there is a thick ring. As you go towards the core, there are different sizes of the rings. This tree lived from 1441-1931. The thick ring (during warm weather) was the time when it was 1880s to early 1900s. This record shows that during that time global warming was taking place.
THE ATMOSPHERE

The graph shows of how much of the carbon dioxide is actually needed and also the record of how much we have. As it goes from past to present, it shows bigger difference in the carbon dioxide that we actually expected and observed. I think what caused this to change is the human activities.
