(Gain attention) President Barack Obama once said “There’s one issue that will define the contours of this century more dramatically than any other, and that is the urgent threat of a changing climate.”
(Reveal Topic) This statement by President Obama on climate change conveys how important the fight against climate change is.
(Establish Credibility) I became interested in this topic after getting into a disagreement regarding climate change with my grandfather and how he doesn’t “buy into that liberal bullshit,” so I set out on a mission to prove him wrong by conducting research with the goal of fully understanding the climate change debate.

Both of these pieces of information show a slight temperature increase, which may not sound significant, but if the temperature continues rising at the rate that it currently is, then a temperature increase will have consequences such as a rise in sea level, change in rainfall patterns and ecosystems and more dangerous and frequent extreme weather
Another aspect proving climate change’s existence is the increase in ocean acidification.
Increased carbon dioxide in the air is causing rapid ocean acidification to occur.
Ocean acidification is when carbon dioxide is absorbed by seawater and reduces the seawater’s pH level and since the industrial revolution, the acidity of surface ocean waters has increased by 30%.
Ocean acidification is dangerous because in more acidic waters, calcium carbonate is more difficult to absorb.
This affects coral reefs and is leading to shrinking of the reefs and may eventually lead to the total destruction of reefs.
The calcium carbonate dilemma also affects snails, clams, and urchins who utilize calcium carbonate to form their
