Climate change and the long term effects that come with it is something that most people agree is an issue that needs to be combated.  The global temperature increase is mainly caused by human activities, which produce gasses that trap heat in our atmosphere.  These greenhouse gasses have increased from human activity, and, as seen by my graphs below, are still increasing, furthering climate change.  When most people think of a greenhouse gas, they think of carbon dioxide being emitted into the atmosphere.  As seen below, between 1990 and 2015, the net emissions of carbon dioxide increased by 51% globally.  This is a real issue, as three-fourths of total global emissions come from carbon dioxide, so it is a major contributor to global warming.  Carbon dioxide was not the only greenhouse gas that has increased globally; as seen below, methane increased as well.  Methane was actually the gas in the data set that increased the least, only 17%, but as you can see from the graph, even the gas that increased the least still consistently increased in recent years.  Other gasses that are not pictured in the graphs but increased include nitrous oxide and fluorinated gasses.  No matter how you look at it, the way these greenhouse gasses have consistently increased globally is a sign we need to make real changes to combat this issue before it gets even more out of hand.
