Background Paragraph: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth’s temperature, known as global warming or global climate change. 
Story: One year,due to extreme use of fossil fuels, an astronomical amount of carbon dioxide is released into the atmosphere due to burning fossil fuels. Many places become much hotter than usual. Another study is done and it is found that the Earths temperature has increased by 4 degrees on average.
Given that even more carbon dioxide is added to the atmosphere, will the temperature increase or decrease?
