The meta-analysis evaluated 60 studies from countries around the globe; some of these studies even went back hundreds of years to the ancient Mayan civilization and Cambodia's Khmer civilization. After reanalyzing these selected studies, the researchers discovered patterns of human belligerence: "for each 1 standard deviation (1σ) change in climate toward warmer temperatures or more extreme rainfall," aggression and violence in interpersonal groups rises 4 percent, and aggression rises 14 percent between people of different social groups (intergroup violence.).
Why does temperature change make us so bellicose?
What does this all mean for the world's future?
If the temperature continues to rise due to the emission of greenhouse gases, then we should expect to see a rise in the acts of violence in the years to come. Whether in the form of wars, rapes, homicides, political instability, or the unceasing noise of irritable people blowing their horns in the street, acts of aggression and hostility will become even more common. The researchers of this study estimated that an increase of 2 degrees Celsius can increase group conflicts by more than 50 percent, and personal crimes can increase by 15 percent.
However, this study does NOT guarantee that any of the predictions put forth will happen. Like most science ideas, it is merely a hypothesis that needs way more evidence and accord within the science community before it is truly accepted. Nevertheless, it is better to be safe then sorry, so I am hoping that this study allows people to look at global warming from a different perspective. I understand that some people, especially those that live inland, might think that rising sea levels will not affect them, so hopefully this study will allow them to view global warming from a new angle, and give them the personal motive to live greener lives.
What are your thoughts about this study? Do you think that there really is a correlation between global warming and an increase in acts of violence? Some people believe that this study makes sweeping conclusions, and that there is not enough solid evidence; do you agree? Please share your thoughts below. I am very curious to see what you have to say about this very interesting- and controversial-topic.

Having said that, I do think global warming (or climate change) will lead to more violence and aggression. As you pointed out, many people will be displaced and we'll probably also be fighting over dwindling resources. Yes, we should worry -- and not just those of us living near the coast!
