Climatic Apocalypse! Yay!

                Today in Human Geography we started our environmental geography PowerPoint. This PowerPoint is about climate change and global warming. First there was a slide talking about the video we were going to watch. There weren’t any real notes to take on this slide. Once the video started, we got a great 10 second look at a Viagra commercial before Mr. Schick turned the projector off. Once the commercial was over, we began the video. I have heard about the greenhouse effect before, but never really heard proof behind it. Before watching the video I thought that climate change was based more off of the earth’s axis changing, but I’ve changed my perspective a little bit after hearing about the 1.4-1.2 degree increase in overall world temperature in the time presented. The video first explained how global warming worked, where greenhouse gases trap and release certain amounts of radiation from the sun on the Earth’s surface. Human machines are producing greenhouse gases, upsetting the atmospheric balance. This causes more radiation to be trapped in Earth’s atmosphere, which in turn causes the temperature to rise.
